Apple Canceling Some Apple Arcade Game Contracts to Focus on Hit Games That Will Draw Subscribers

Apple is shifting its Apple Arcade strategy and canceling contracts for some games while pursuing titles that it thinks will help it better retain subscribers, reports Bloomberg.

Apple earlier this year ended contracts with multiple game studios and let them know about its new approach to choosing games for the service. Some upcoming games Apple had planned to support didn’t have a high enough level of “engagement” as Apple is now looking for games that will “keep users hooked.”

In one call, Apple highlighted Grindstone as the type of game that it wants to see on the platform. Grindstone is a multi-level match-3 puzzle game.

So far, no ‌Apple Arcade‌ games have become major hits, and there’s no word on how well ‌Apple Arcade‌ is doing. Some developers have speculated that Apple’s strategy change indicates subscriber growth is weaker than expected, and Apple also recently began offering some people a second free trial month, which perhaps suggests that users aren’t remaining subscribers for a long enough period of time.

In a statement to Bloomberg, Apple said that its vision has always been to try to “grow and evolve the ‌Apple Arcade‌ catalog” and that it has always planned to make changes to the game lineup based on feedback from subscribers.

“‌Apple Arcade‌ has redefined what a gaming service can be, putting unlimited play at the fingertips of subscribers and their families across all their Apple devices,” Apple said in a statement. “We are proud to have launched the first-ever mobile game subscription service that now features more than 120 games, many of which are award-winning and widely celebrated for their artistry and gameplay. The vision has always been to grow and evolve the ‌Apple Arcade‌ catalog, and we can’t wait for our users to try the games developers are working on now.”

Apple unveiled ‌Apple Arcade‌ in September 2019, pricing it at $4.99 per month. ‌Apple Arcade‌ games are available to all members of a family at that price point, and contain no ads or in-app purchases.

Since ‌Apple Arcade‌ launched, Apple has added new games on a near-weekly basis, and there are now more than 120 titles available. Apple has funded work on many games that have been created for ‌Apple Arcade‌, spending between $1 million and $5 million on several titles so far.

Remote access at risk: Pandemic pulls more cyber‑crooks into the brute‑forcing game – 10 minute mail

Poorly secured remote access attracts mostly ransomware gangs, but can provide access to coin miners and backdoors too

The COVID-19 pandemic has radically changed the nature of everyday work, forcing employees to do large parts of their jobs via remote access. Cybercriminals – especially ransomware operators – are aware of the shift and attempt to exploit the new opportunities and increase their illicit earnings. ESET telemetry confirms this trend in an uptick in the number of unique clients who reported brute-force attack attempts blocked via ESET’s network attack detection technology.

Before the lockdown, most employees worked from the office and used infrastructure monitored and controlled by their IT department. But the coronavirus pandemic has brought a major shift to the status quo. Today, a huge proportion of “office” work occurs via home devices with workers accessing sensitive company systems through Windows’ Remote Desktop Protocol (RDP) – a proprietary solution created by Microsoft to allow connecting to the corporate network from remote computers.

Despite the increasing importance of RDP (as well as other remote access services), organizations often neglect its settings and protection. Employees use easy-to-guess passwords and with no additional layers of authentication or protection, there is little that can stop cybercriminals from compromising an organization’s systems.

That is probably also the reason why RDP has become such a popular attack vector in the past few years, especially among ransomware gangs. These cybercriminals typically brute-force their way into a poorly secured network, elevate their rights to admin level, disable or uninstall security solutions and then run ransomware to encrypt crucial company data.

The growing number of unique clients who have reported an RDP attack attempt is visible in data gathered by ESET telemetry (see Figure 1).

Figure 1. Trend of RDP attack attempts against unique clients (per day), detected by ESET technologies

Brute-force attack protection

To address the growing risks posed by increasing RDP use, ESET researchers have devised a new detection layer that is hidden under the hood of ESET Network Attack Protection and is designed to block incoming brute-force attacks from external IP addresses, covering RDP as well as SMB protocols.

Called ESET Brute-Force Attack Protection, this new layer detects groups of failed login attempts from external environments, which hint at an incoming brute-force attack, and then blocks further attempts. Subsequently, the biggest offenders among these IP addresses are added to a blacklist, which protects millions of devices from future attacks.

The new technology has proven to be effective against both random and targeted attacks. For it to work properly, the RDP option Network Level Authentication (NLA) on server must be enabled.

According to ESET telemetry, most of the blocked IPs in January–May 2020 were seen in the United States, China, Russia, Germany and France (see Figure 2).

Figure 2. Countries with the largest number of all blocked IP addresses (between Jan 1 and May 31, 2020).

Countries that had the largest proportion of targeted IPs were Russia, Germany, Japan, Brazil and Hungary (see Figure 3).

Figure 3. Countries with the most brute-force attacks reported by ESET telemetry (between Jan 1 and May 31, 2020).

How to configure remote access correctly

Yet, even with protective measures such as ESET Brute-Force Attack Protection, organizations need to keep their remote access properly configured:

  • Disable internet-facing RDP. If that is not possible, minimize the number of users allowed to connect directly to the organization’s servers over the internet.
  • Require strong and complex passwords for all accounts that can be logged into via RDP.
  • Use an additional layer of authentication (MFA/2FA).
  • Install a virtual private network (VPN) gateway to broker all RDP connections from outside your local network.
  • At the perimeter firewall, disallow external connections to local machines on port 3389 (TCP/UDP) or any other RDP port.
  • Protect your endpoint security software from tampering or uninstallation by password-protecting its settings.
  • Isolate any insecure or outdated computers that need to be accessed from the internet using RDP and replace them as soon as possible.
  • For a detailed description of how to set up your RDP connection correctly, please refer to this article by ESET Distinguished Researcher Aryeh Goretsky.
  • Most of these best practices apply to FTP, SMB, SSH, SQL, TeamViewer, VNC and other services as well.

Ransomware, coin miners and backdoors

Encryption of data and subsequent extortion is in no way the only scenario that could follow an RDP compromise. Frequently the attackers try to install coin-mining malware or create a backdoor, which can be used in case their unauthorized RDP access has been identified and closed.

Other common scenarios following an RDP compromise can include:

  • clearing of log files, thus removing the evidence of previous malicious activity,
  • downloading and running the attacker’s choice of tools and malware on the compromised system,
  • disabling of scheduled backups and shadow copies or completely erasing them, or
  • exfiltrating data from the server.

Black hats have been trying to exploit RDP for years, as documented by our blogpost from 2013. Steadily growing numbers of RDP attacks over the past few years have become the subject of numerous governmental advisories including the FBI, the UK’s NCSC and Australia’s ACSC.

This only demonstrates how crucial the security of remote access has become, potentially making or breaking a company’s future. And even if the damage to an organization’s reputation can be managed, there are financial losses, stalled operations and expensive recovery efforts that need to be accounted for. This doesn’t consider the additional costs of potential penalties that can be issued by authorities under data-protective legislation such as GDPR (EU), CCPA (California) or NDB (Australia).

Whether or not there’s a pandemic, businesses should manage the risks posed by wide usage of RDP or other similar services by reinforcing their passwords and by adding other protective layers, including multi-factor authentication and a security solution that defends against attacks based on RDP and similar protocols.

Apple Revives and Refreshes Game Center in iOS 14 and macOS Big Sur

Game Center, a feature for tracking game progress and connecting gamers together for multiplayer gameplay experiences, has long been a part of iOS.

Game Center achievements in Settings

The feature was added to iOS 4 in 2010 and was a key part of gaming for a few years, but Apple nixed the Game Center app in 2016 with the release of iOS 10. Game Center has stuck around since then, but as more of a behind the scenes feature.

Apple’s latest software releases revive Game Center, and there’s a redesigned Game Center dashboard available on iOS, tvOS, and macOS that games can take advantage of.

Users are able to view their achievements, leaderboards, and Game Center profiles directly within various games through a new in-game dashboard in ‌Apple Arcade‌ games and through the updated Game Center section in the Settings app.

Game Center now offers up recurring leaderboards for current game rankings along with leaderboards for daily, weekly, and monthly competitions, plus a feature that lets users see their friends’ game progress. Apple will also use Game Center in ‌Apple Arcade‌ to let users see what games are popular with their friends.

Gamaredon group grows its game – 10 minute mail

Active APT group adds cunning remote template injectors for Word and Excel documents; unique Outlook mass-mailing macro

ESET researchers have discovered several previously undocumented post-compromise tools used by the highly active Gamaredon threat group in various malicious campaigns. One tool, a VBA macro targeting Microsoft Outlook, uses the target’s email account to send spearphishing emails to contacts in the victim’s Microsoft Office address book. We also analyzed further Gamaredon tools that have the ability to inject malicious macros and remote templates into existing Office documents.

Tools linked to Gamaredon and discussed in this blogpost are detected as variants of MSIL/Pterodo, Win32/Pterodo or Win64/Pterodo by ESET’s products.

The Gamaredon group has been active since at least 2013. It has been responsible for a number of attacks, mostly against Ukrainian institutions, as evidenced in several reports from CERT-UA and from other official Ukrainian bodies over time.

In the last few months, there has been an increase in activity from this group, with constant waves of malicious emails hitting their targets’ mailboxes. The attachments to these emails are documents with malicious macros that, when executed, try to download a multitude of different malware variants.

Gamaredon has leveraged many different programming languages in the past few months, ranging from C# to VBScript, batch files and C/C++. The tools used by Gamaredon are very simple and are designed to gather sensitive information from compromised systems and to spread further.

Contrary to other APT groups, the Gamaredon group seems to make no effort in trying to stay under the radar. Even though their tools have the capacity to download and execute arbitrary binaries that could be far stealthier, it seems that this group’s main focus is to spread as far and fast as possible in their target’s network while trying to exfiltrate data. Could we be missing something?


Figure 1 illustrates a typical compromise chain in a Gamaredon campaign.

Figure 1. Typical Gamaredon compromise chain

While most of the recent publications have focused on the spearphishing emails together with the downloaders they contain, this blogpost focuses on the post-compromise tools deployed on these systems.

Outlook VBA module

The Gamaredon group uses a package that includes a custom Microsoft Outlook Visual Basic for Applications (VBA) project. Using Outlook macros to deliver malware is something we rarely see while investigating malicious campaigns.

This bundle of malicious code starts out with a VBScript that first kills the Outlook process if it is running, and then removes security around VBA macro execution in Outlook by changing registry values. It also saves to disk the malicious OTM file (Outlook VBA project) that contains a macro, the malicious email attachment and, in some cases, a list of recipients that the emails should be sent to.

Next, it relaunches Outlook with a special option, /altvba , which loads the Gamaredon VBA project. The malicious code is executed once the Application.Startup event is received. They have been using this module in three different ways to send malicious email to:

  • Everyone in the victim’s address book
  • Everyone within the same organization
  • A predefined list of targets

While abusing a compromised mailbox to send malicious emails without the victim’s consent is not a new technique, we believe this is the first publicly documented case of an attack group using an OTM file and Outlook macro to achieve it.

Figure 2. Outlook VBA script creating the malicious email

Based on the “send to all in contact list” behavior of this malicious VBA code, we believe that this module might have led some organizations to think they were targeted by Gamaredon when they were merely collateral damage. For example, recent samples uploaded to VirusTotal coming from regions that are not traditionally targeted by Gamaredon, such as Japan, could be explained by the actions of this module.

As seen in Figure 2, the VBA code builds the email body and attaches the malicious document to the email. We’ve seen both .docx and .lnk files being used as attachments. These are very similar to the content of the malicious attachments used in Gamaredon’s initial spearphishing campaigns. Figure 3 shows an email generated by this malicious component.

Figure 3. Email generated by the Outlook VBA module with a Word document attachment that contains a remote template

The email contains both English and Russian text. However, as illustrated in Figure 3, there is a problem with the Russian encoding. This was fixed in a later version of this module — another example of the Gamaredon group’s fast development pace and apparent lack of attention to detail.

Office macro injection module – CodeBuilder

We analyzed different variants of malicious modules used by the Gamaredon group to inject malicious macros or remote templates into documents already present on the compromised system. This is a very efficient way of moving laterally within an organization’s network as documents are routinely shared amongst colleagues. Also, as these macros are run when opening the documents, it is a good way to persist on a system as some of these documents are likely to be opened multiple times and at different times.

These macro injection modules also have the functionality to tamper with the Microsoft Office macro security settings. Thus, affected users have no idea that they are again compromising their workstations whenever they open the documents. We have seen this module implemented in two different languages: C# and VBScript.


This module was delivered, like many other tools, in a 7z self-extracting archive. Inside, there was a password-protected RAR archive containing a few files. Notably, there were two text files, one for Word and one for Excel, containing the VBA source code of the malicious macro to be inserted into the targeted documents, and the .NET assembly responsible for finding and compromising existing documents. As illustrated in Figure 4, the assembly name is CodeBuilder.

Figure 4. CodeBuilder functions in a version that is not obfuscated

This .NET module first reduces Office macro security settings for various document types by modifying the following registry values:


It iterates over all possible Office values for both Word and Excel values. It then scans for documents with valid Word or Excel file extensions on all drives connected to the system. For the drive containing the Windows installation, it scans only specific locations, namely the Desktop and Downloads folders. For the others, it scans the entire drive. The malware moves each located document into the AppData folder, inserts malicious Word or Excel macros into it using a Microsoft.Office.Interop object, and then moves the document back into its original folder. In the samples we analyzed, the injected macros were simple downloaders.

Batch file/VBScript

The VBScript version of this module is similar in behavior to the .NET one. The main difference is that instead of inserting a malicious macro into existing documents, it inserts references to a remote template into them.

Figure 5. VBScript using the Document.AttachedTemplate property to inject a reference to a remote template into existing documents

This VBScript module also comes packaged in a self-extracting archive, containing one batch file and two VBS files responsible for iterating through documents and adding the remote template references to them.

Module updates

Interestingly, some of the custom tools described in Palo Alto Networks’ 2017 blogpost on Gamaredon are still being updated and in use today. Some show significant similarities while others are rewrites in different coding languages. The most prevalent tools downloaded and installed on compromised machines can be broadly grouped into two different categories: downloaders and backdoors.


There are many variations of their downloaders, most of them written in either C# or VBScript. This section will cover only two of their most original variants; the others have not evolved that much and are very simple.

C# compiler module

This .NET executable, similar to many other tools used by the Gamaredon group, uses obfuscation techniques such as junk code insertion and string obfuscation. It contains in its body the base64-encoded source code of a downloader. It decodes that source code and compiles it directly on the system using the built-in Microsoft.CSharp.CSharpCodeProvider class. It places the resulting executable in an existing directory and creates a scheduled task that will launch it every 10 minutes. As can be seen in Figure 6, the decoded source code still has comments in it, illustrating the apparent sloppiness of Gamaredon’s operators.

Figure 6. Part of the C# downloader source code included in the C# compiler module

GitHub project module

As seen in Figure 7, this .NET executable uses a GitHub repository to obtain and execute a downloader. This repository is now gone, but we were able to download a copy of it while it was still available.

Figure 7. .NET module responsible for downloading and executing a payload stored on

The repository contained a single file — readme.txt — that was a base64-encoded .NET downloader executable. The role of the GitHub project module is to download this file, decode it and execute it.

Backdoors – file stealers

While some variations exist in functionalities, the main purpose of these modules is to enumerate all documents on a compromised system and upload them to the C&C server. These file stealers can also download and execute arbitrary code from the C&C server. As with many other tools used by the Gamaredon group, they come in four different coding languages: C/C++, C#, batch file and VBScript.


This variant is the successor of the USBStealer module described here. Although the latest versions are now quite different, examining samples of this module throughout its development clearly shows it originates from the same source code.

One sample that illustrates this shift well is a 64-bit DLL with internal name Harvesterx64.dll, compiled in June 2019. It still has most of the strings used in the older variants, but also exhibits two improvements that are still in the newer ones. First, it now resolves Windows APIs via name hashing and second, it uses a basic text file instead of a SQLite database to track which files were already uploaded to the C&C server.

The behavior of this module is quite straightforward: it scans the system for new Microsoft Office documents, both on local and removable drives, and uploads them to the C&C server. To know whether the document is new, the module keeps, in a text file, one MD5 hash per file uploaded to the server. These MD5 hashes are not based on the file content, but rather on a string composed of the file name, its size and its last modified time. The module’s strings are stored in its .data section, encrypted with a simple XOR key. It also has the ability to download and execute arbitrary code from its C&C server.


This is a reimplementation in C# of the C/C++ version. The major difference is that it also takes screenshots of the compromised computer every minute. As seen in Figure 8, the version we analyzed has five different threads with evocative names.

Figure 8. C# backdoor thread creation routine

Batch file/VBScript

This version comprises several scripts, written in both batch file form and VBScript. The ultimate goal is the same, though: scanning the system for sensitive documents. The main mechanism is a batch file that searches for Word documents (*.doc*) on the system and stores their names in a text file (see Figure 9).

Figure 9.Example inject.txt file containing the result of the backdoor’s document file scan

The package also contains encrypted script files named 1.log, 2.log, 3.log, 4.log and 5.log. Once decrypted, these scripts are obfuscated VBScript downloaders that are able to download and execute arbitrary code.

Network infrastructure

The Gamaredon group uses many different domains, both free and paid, for its C&C servers. Free domains are mostly DDNS from No-IP:,,, while paid domains are registered through the REG.RU registrar and include the .fun, .site, .space, .ru, .website and .xyz TLDs.

They are constantly changing the domains used by their tools, but mostly on a small number of ASNs. Careful analysis suggests they use separate domains for small groups of victims. Please check ESET’s GitHub account for an extensive list of domains used by the Gamaredon group.

Quality of execution

We were able to collect numerous different samples of malicious scripts, executables and documents used by the Gamaredon group throughout their campaigns. We noticed several mistakes in these, especially in scripts. It is of course impossible to know the exact reason behind these bugs or oversights, but the volume of samples the group produces and their rapid development could explain it. The fact that there were comments left in the source code included in some C# compiler module samples or that the Russian encoding was wrong in email generated by the Outlook VBA module shows that there is no stringent review or testing before releasing their many tools and using them in the wild.

However, while these errors might lower their tools’ overall effectiveness, this group’s rapid execution and adaptation also has some advantages. The volume and relentlessness of the attacks can create a state of constant dread in their targets. And although the code is very simple, some techniques, such as script obfuscation, make it hard to fully automate the analysis, making the analyst’s job tedious.

Their GitHub project allowed us a glimpse into the rapid development of their tools. The code that was committed there clearly showed the evolution of the C# downloader. The first versions showed no signs of obfuscation; then the developers added different string obfuscations and junk code to make the analysis harder.

In terms of persistence, several different techniques are used, but the most common ones are scheduled tasks, autorun registry keys and leveraging the Startup folder. Although these techniques are very simple and have been known for a long time, the Gamaredon group’s strategy of trying to install multiple scripts and executables on each system, and constantly updating them, significantly complicates the defender’s lives.


Despite the simplicity of most of their tools, the Gamaredon group also is capable of deploying some novelty, such as their Outlook VBA module. However, as it is far from stealthy, in the long run it is no match for a capable organization. The variety of tools Gamaredon has at its disposal can be very effective at fingerprinting a machine and understanding what sensitive data is available, then spreading throughout the network. Could this just be a way to deploy a much stealthier payload?

No “Game over” for the Winnti Group – 10 minute mail

The notorious APT group continues to play the video game industry with yet another backdoor

In February 2020, we discovered a new, modular backdoor, which we named PipeMon. Persisting as a Print Processor, it was used by the Winnti Group against several video gaming companies that are based in South Korea and Taiwan and develop MMO (Massively Multiplayer Online) games. Video games developed by these companies are available on popular gaming platforms and have thousands of simultaneous players.

In at least one case, the malware operators compromised a victim’s build system, which could have led to a supply-chain attack, allowing the attackers to trojanize game executables. In another case, the game servers were compromised, which could have allowed the attackers to, for example, manipulate in-game currencies for financial gain.

The Winnti Group, active since at least 2012, is responsible for high-profile supply-chain attacks against the software industry, leading to the distribution of trojanized software (such as CCleaner, ASUS LiveUpdate and multiple video games) that is then used to compromise more victims. Recently, ESET researchers also discovered a campaign of the Winnti Group targeting several Hong Kong universities with ShadowPad and Winnti malware.

About the “Winnti Group” naming:

We have chosen to keep the name “Winnti Group” since it’s the name first used to identify it, in 2013, by Kaspersky. Since Winnti is also a malware family, we always write “Winnti Group” when we refer to the malefactors behind the attacks. Since 2013, it has been demonstrated that Winnti is only one of the many malware families used by the Winnti Group.

Attribution to the Winnti Group

Multiple indicators led us to attribute this campaign to the Winnti Group. Some of the C&C domains used by PipeMon were used by Winnti malware in previous campaigns mentioned in our white paper on the Winnti Group arsenal. Besides, Winnti malware was also found in 2019 at some of the companies that were later compromised with PipeMon.

In addition to Winnti malware, a custom AceHash (a credential harvester) binary found at other victims of the Winnti Group, and signed with a well-known stolen certificate used by the group (Wemade IO), was also used during this campaign.

The certificate used to sign the PipeMon installer, modules and additional tools is linked to a video game company that was compromised in a supply-chain attack in late 2018 by the Winnti Group and was likely stolen at that time.

Interestingly, PipeMon modules are installed in %SYSTEM32%spoolprtprocsx64; this path was also used in the past to drop the second stage of the trojanized CCleaner.

Additionally, compromising a software developer’s build environment to subsequently compromise legitimate application is a known modus operandi of the Winnti Group.

Targeted companies

Companies targeted in this campaign are video game developers, producing MMO games and based in South Korea and Taiwan. In at least one case, the attackers were able to compromise the company’s build orchestration server, allowing them to take control of the automated build systems. This could have allowed the attackers to include arbitrary code of their choice in the video game executables.

ESET contacted the affected companies and provided the necessary information to remediate the compromise.

Technical analysis

Two different variants of PipeMon were found at the targeted companies. Only for the more recent variant were we able to identify the first stage which is responsible for installing and persisting PipeMon.

First stage

PipeMon’s first stage consists of a password-protected RARSFX executable embedded in the .rsrc section of its launcher. The launcher writes the RARSFX to setup0.exe in a directory named with a randomly generated, eight-character, ASCII string located in the directory returned by GetTempPath. Once written to disk, the RARSFX is executed with CreateProcess by providing the decryption password in an argument, as follows:

setup0.exe -p*|T/PMR{|T2^LWJ*

Note that the password is different with each sample.

The content of the RARSFX is then extracted into %TMP%RarSFX0 and consists of the following files:

  • CrLnc.dat – Encrypted payload
  • Duser.dll – Used for UAC bypass
  • osksupport.dll – Used for UAC bypass
  • PrintDialog.dll – Used for the malicious print processor initialization
  • PrintDialog.exe – Legitimate Windows executable used to load PrintDialog.dll
  • setup.dll – Installation DLL
  • setup.exe – Main executable

Note that in the event of a folder name collision, the number at the end of the RarSFX0 string is incremented until a collision is avoided. Further, not all these files are necessarily present in the archive, depending on the installer.

Once extracted, setup.exe is executed without arguments. Its sole purpose is to load setup.dll using LoadLibraryA. Once loaded, setup.dll checks whether an argument in the format –x:n (where n is an integer) was provided; the mode of operation will be different depending on the presence of n. Supported arguments and their corresponding behavior are shown in Table 1. setup.exe is executed without arguments by the RARSFX, and checks whether it’s running with elevated privileges. If not, it will attempt to obtain such privileges using token impersonation if the version of Windows is below Windows 7 build 7601; otherwise it will attempt different UAC bypass techniques, allowing installation of the payload loader into one of:

  • C:WindowsSystem32spoolprtprocsx64DEment.dll
  • C:WindowsSystem32spoolprtprocsx64EntAppsvc.dll
  • C:WindowsSystem32spoolprtprocsx64Interactive.dll

depending on the variant. Note that we weren’t able to retrieve samples related to Interactive.dll.

Table 1. setup.exe supported arguments and their corresponding behavior.

Command line argument value Behavior
-x:0 Load the payload loader.
-x:1 Attempt to enable SeLoadDriverPrivilege for the current process. If successful, attempt to install the payload loader; otherwise, restart setup.exe with the –x:2 argument using parent process spoofing.
-x:2 Attempt to enable SeLoadDriverPrivilege for the current process. If successful, attempt to install the payload loader.

This loader is stored encrypted within setup.dll, which will decrypt it before writing it to the aforementioned location.

Persistence using Windows Print Processors

The location where the malicious DLL is dropped was not chosen randomly. This is the path where Windows Print Processors are located and setup.dll registers the malicious DLL loader as an alternative Print Processor by setting one of the following registry values:

HKLMSYSTEMControlSet001ControlPrintEnvironmentsWindows x64Print ProcessorsPrintFiiterPipelineSvcDriver = “DEment.dll”


HKLMSYSTEMCurrentControlSetControlPrintEnvironmentsWindows x64Print Processorslltdsvc1Driver = “EntAppsvc.dll”

depending on the variant. Note the typo in PrintFiiterPipelineSvc (which has no impact on the Print Processor installation since any name can be used).

After having registered the Print Processor, PipeMon restarts the print spooler service (spoolsv.exe). As a result, the malicious print process is loaded when the spooler service starts. Note that the Print Spooler service starts at each PC startup, which ensures persistence across system resets.

This technique is really similar to the Print Monitor persistence technique (being used by DePriMon, for example) and, to our knowledge, has not been documented previously.

Additionally, the encrypted payload, CrLnc.dat, extracted from the RARSFX is written to the registry at the following location, depending on the installer:

  • HKLMSOFTWAREMicrosoftPrintComponentsDC20FD7E-4B1B-4B88-8172-61F0BED7D9E8
  • HKLMSOFTWAREMicrosoftPrintComponentsA66F35-4164-45FF-9CB4-69ACAA10E52D

This encrypted registry payload is then loaded, decrypted and executed by the previously registered Print Processor library. The whole PipeMon staging and persistence is shown in Figure 1.

Figure 1. PipeMon staging and persistence


We named this new implant PipeMon because it uses multiple named pipes for inter-module communication and according to its PDB path, the name of the Visual Studio project used by its developer is “Monitor”.

As mentioned previously, two different PipeMon variants were found. Considering the first variant, we couldn’t retrieve the installer; thus, we don’t know for sure the persistence technique that was used. But considering that this first variant of PipeMon was also located in the Print Processor directory, it’s likely that the same persistence mechanism was used.

Original variant

PipeMon is a modular backdoor where each module is a single DLL exporting a function called IntelLoader and is loaded using a reflective loading technique. Each module exhibits different functionalities that are shown in Table 2.

The loader, responsible for loading the main modules (ManagerMain and GuardClient) is Win32CmdDll.dll and is located in the Print Processors directory. The modules are stored encrypted on disk at the same location with inoffensive-looking names such as:

  • banner.bmp
  • certificate.cert
  • License.hwp
  • JSONDIU7c9djE
  • B0SDFUWEkNCj.logN

Note that .hwp is the extension used by Hangul Word Processor from Hangul Office, which is very popular in South Korea.

The modules are RC4 encrypted and the decryption key Com!123Qasdz is hardcoded into each module. Win32CmDll.dll decrypts and injects the ManagerMain and GuardClient modules. The ManagerMain module is responsible for decrypting and injecting the Communication module, while the GuardClient module will ensure that the Communication module is running and reload it if necessary. An overview of how PipeMon operates is shown in Figure 2.

Win32CmDll.dll first tries to inject the ManagerMain and GuardClient modules into a process with one of the following names: lsass.exe, wininit.exe or lsm.exe. If that fails, it tries to inject into one of the registered windows services processes, excluding processes named spoolsv.exe, ekrn.exe (ESET), avp.exe (Kaspersky) or dllhost.exe. As a last option, if everything else failed, it tries to use the processes taskhost.exe, taskhostw.exe or explorer.exe.

The process candidates for Communication module injection must be in the TCP connection table with either as the local address, or an ESTABLISHED connection and owning a LOCAL SERVICE token. These conditions are likely used to hide the Communication module into a process that is already communicating over the network so that the traffic from the Communication module would seem inconspicuous and possibly also whitelisted in the firewall. If no process meets the previous requirements, the ManagerMain module tries to inject the Communication module into explorer.exe. Processes belonging to the Windows Store Apps and processes named egui.exe (ESET) and avpui.exe (Kaspersky) are ignored from the selection.

Table 2. PipeMon module descriptions and their respective PDB paths

Module Name Description PDB Path
Win32CmdDll Decrypts and loads the ManagerMain and GuardClient modules. S:MonitorMonitor_RAWLauncherx64ReleaseWin32CmdDll.pdb
GuardClient Periodically checks whether the Communication module is running and loads it if not. S:MonitorMonitor_RAWClientx64ReleaseGuardClient.pdb
ManagerMain Loads Communication module when executed. Contains encrypted C&C domain which is passed to the Communication module via named pipe.
Can execute several commands based on the data received from the Communication module (mostly system information collecting, injecting payloads).
Communication Responsible for managing communication between the C&C server and individual modules via named pipes. S:MonitorMonitor_RAWClientx64ReleaseCommunication.pdb

Additional modules can be loaded on-demand using dedicated commands (see below), but unfortunately, we weren’t able to discover any of them. The names of these modules are an educated guess based on the named pipes used to communicate with them:

  • Screen
  • Route
  • CMD
  • InCmd
  • File

Inter-module communication

Inter-module communication is performed via named pipes, using two named pipes per communication channel between each individual module, one for sending and one for receiving. Table 3 lists the communication channels and their corresponding named pipes.

Table 3. PipeMon communication channel and their respective named pipes

Communication channel Named pipe
Communication, Screen \.pipeScreenPipeRead%CNC_DEFINED%
Communication, Route \.pipeRoutePipeWriite%B64_TIMESTAMP%
Communication, ManagerMain \.pipeMainPipeWrite%B64_TIMESTAMP%
GuardClient, ManagerMain \.pipeMainHeatPipeRead%B64_TIMESTAMP%
Communication, InCmd \.pipeInCmdPipeWrite%B64_TIMESTAMP%
Communication, File \.pipeFilePipeRead%B64_TIMESTAMP%
GuardClient, Communication \.pipeComHeatPipeRead%B64_TIMESTAMP%
Communication, CMD \.pipeCMDPipeRead

The %CNC_DEFINED% string is received from the C&C server and %B64_TIMESTAMP% variables are base64-encoded timestamps such as the ones shown in Table 4.

Table 4. Example timestamps used with named pipes

%BASE64_TIMESTAMP% Decoded timestamp
MjAxOTAyMjgxMDE1Mzc= 20190228101537
MjAxOTA1MjEyMzU2MjQ= 20190521235624
MjAxOTExMjExMjE2MjY= 20191121121626

Figure 2. PipeMon IPC scheme (original PipeMon variant)

C&C communication

The Communication module is responsible for managing communications between the C&C server and the other modules via named pipes, similar to the PortReuse backdoor documented in our white paper on the Winnti arsenal.

Its C&C address is hardcoded in the ManagerMain module and encrypted using RC4 with the hardcoded key Com!123Qasdz. It is sent to the Communication module through a named pipe.

A separate communication channel is created for each installed module. The communication protocol used is TLS over TCP. The communication is handled with the HP-Socket library. All the messages are RC4 encrypted using the hardcoded key. If the size of the message to be transferred is greater than or equal to 4KB, it is first compressed using zlib’s Deflate implementation.

Figure 3. C&C message and beacon formats

To initiate communication with the C&C server, a beacon message is first sent that contains the following information:

  • OS version
  • physical addresses of connected network adapters concatenated with %B64_TIMESTAMP%
  • victim’s local IP address
  • backdoor version/campaign ID; we’ve observed the following values
    • “”
    • “”
    • “”
  • Victim computer name

The information about the victim’s machine is collected by the ManagerMain module and sent to the Communication module via the named pipe. The backdoor version is hardcoded in the Communication module in cleartext.

The format of the beacon message is shown in Figure 3 and the supported commands are shown in Table 5.

Table 5. List of commands

Command type Command argument Description
0x02 0x03 Install the File module
0x03 0x03 Install the CMD module
0x03 0x0B Install the InCmd module

0x04 0x03 Install the Route module
0x05 * Send victim’s RDP information to the C&C server
0x06 0x05 Send OS, CPU, PC and time zone information to the C&C server
0x06 0x06 Send network information to the C&C server
0x06 0x07 Send disk drive information to the C&C server
0x07 * Send running processes information to the C&C server
0x09 * DLL injection

0x0C 0x16 Send name of “Route” pipe to the C&C server
0x0C 0x17 Send names of “File” pipes to the C&C server

* The argument supplied for this command type is ignored

Updated variant

As mentioned earlier, the attackers also use an updated version of PipeMon for which we were able to retrieve the first stage described above. While exhibiting an architecture highly similar to the original variant, its code was likely rewritten from scratch.

The RC4 code used to decrypt the modules and strings was replaced by a simple XOR with 0x75E8EEAF as the key and all the hardcoded strings were removed. The named pipes used for inter-module communication are now named using random values instead of explicit names and conform to the format \.pipe%rand%, where %rand% is a pseudorandomly generated string of 31 characters containing only mixed case alphabetic characters.

Here, only the main loader (i.e. the malicious DLL installed as a Print Processor) is stored as a file on disk; the modules are stored in the registry by the installer (from the CrLnc.dat file) and are described in Table 6.

Table 6. Updated modules

Module name Description
CoreLnc.dll Loaded by the malicious Print Processor. Responsible only for loading the Core.dll module embedded in its .data section.
Core.dll Loads the Net.dll module embedded in its .data section. Handles commands from the C&C server and communications between individual modules and the C&C server through named pipes.
Net.dll New Communication module. Handles the networking.

Module injection is not performed using the reflective loading technique with an export function anymore; custom loader shellcode is used instead and is injected along with the module to be loaded.

The C&C message format was changed as well, and is shown in Figure 4.

Figure 4. Previous (top) and updated (bottom) C&C message format

Interestingly, the backdoor’s configuration is encrypted and embedded in the loader DLL. The configuration contains:

  • Name of the registry value
  • Campaign identifier
  • C&C IP addresses or domain names
  • Timestamp (in FILETIME format) corresponding to the date from which to start using a second C&C domain marked with ‘#’ in the configuration.

An example of a configuration dump embedded in the loader DLL is shown in Figure 5. Configurations extracted from several loader DLLs are shown in Table 7.

Stolen code-signing certificate

PipeMon modules and installers are all signed with the same valid code-signing certificate that was likely stolen during a previous campaign of the Winnti Group. The certificate’s owner revoked it as soon as they were notified of the issue.

Figure 6. Code-signing certificate used to sign PipeMon first stage and modules before (top) and after (bottom) revocation.

We found on a sample sharing platform other tools signed with this certificate, such as HTRan, a connection bouncer, the WinEggDrop port scanner, Netcat, and Mimikatz which may have been used by the attackers as well.

Furthermore, a custom AceHash build signed with a Wemade IO stolen certificate already mentioned in our previous white paper and usually used by the Winnti Group was found on some machines compromised with PipeMon.


Once again, the Winnti Group has targeted video game developers in Asia with a new modular backdoor signed with a code-signing certificate likely stolen during a previous campaign and sharing some similarities with the PortReuse backdoor. This new implant shows that the Winnti Group is still actively developing new tools using multiple open source projects; they don’t rely solely on their flagship backdoors, ShadowPad and the Winnti malware.

We will continue to monitor new activities of the Winnti Group and will publish relevant information on our blog. For any inquiries, contact us at [email protected]. The IoCs are also available at our GitHub repository.

Ubisoft Sues Apple and Google Over Distribution of Alleged ‘Ripoff’ Game

Ubisoft Entertainment this week levied a lawsuit against Apple and Google, accusing them of selling a “ripoff” of its popular video game Tom Clancy’s Rainbow Six: Siege, reports Bloomberg.

Ubisoft filed a complaint in federal court in Los Angeles, claiming that the game “Area F2,” developed by Qookka Games, is a “near carbon copy” of Tom Clancy’s Rainbow Six: Siege, aiming to “piggyback” off its popularity. Ubisoft said that it has notified Apple and Google that Area F2 is infringing its copyrights, but both companies have refused to remove the game from the Google Play and Apple App stores.

As one of Ubisoft’s most valuable intellectual properties, Rainbow Six: Siege is played as a competitive e-sport, has 55 million registered players worldwide, and according to Ubisoft’s copyright infringement claim, is played by more than three million users every day. Ubisoft argues that the lawsuit can’t be “seriously disputed” and that “virtually every aspect of AF2” is copied from Rainbow Six: Siege, “from the operator selection screen to the final scoring screen, and everything in between.”

Ubisoft did not elaborate on why it is suing the app store operators for enabling distribution of the game rather than developer Qookka Games itself for the initial infringement. Qookka Games, owned by Alibaba’s Ejoy, is located in China, potentially making an international copyright claim more difficult. It remains unclear whether Ubisoft plans to file a separate lawsuit against the developer, in addition to app store operators.

Area F2 has over 75,000 reviews on the Google Play Store, and more than 2,000 on Apple’s App Store, and many reviews on both platforms directly note the similarities to Ubisoft’s title. Google and Apple have not yet responded to Bloomberg‘s requests for a comment.
