Phishing Attacks Can Now Dodge Microsoft 365’s Multi-Factor Authentication – Disposable mail news

Of late a phishing attack was found to be stealing confidential user data that was stored on the cloud.
As per sources, this is the work of a new phishing campaign that dodges the Office 365 Multi-Factor Authentication (MFA) to acquire the target’s cloud-stored data and uses it as bait to extract a ransom in Bitcoin.

Per reports, researchers discovered that the campaign influences the “OAuth2 framework and OpenID Connect (OIDC) protocol”. It employs a malicious “SharePoint” link to fool the targets into giving permission to “rogue” applications.

MFAs are used as a plan B in cases where the users’ passwords have been discovered. This phishing attack is different because it tries to fool its targets into helping the mal-actors dodge the MFA by giving permissions.

This campaign is not just about gaining ransoms via exploiting the stolen data it is that and the additional threat of having sensitive and personal information at large for others to exploit as well. Extortion and blackmail are among the first things that the data could be misused for.

Sources mentioned that via obtaining basic emails and information from the target’s device, the attacker could easily design “hyper-realistic Reply-Chain phishing emails.”

The phishing campaign employs a commonplace invite for a SharePoint file, which happens to be providing information regarding a “salary bonus”, which is good enough for perfunctory readers to get trapped, mention reports.

The link when clicked on redirects the target to an authentic login page of Microsoft Office 365. But if looked on closely, the URL looks fishy and created without much attention to detail, thus say the security experts.

Reportedly, access to Office 365 is acquired by getting a token from the Microsoft Identity Platform and then through Microsoft Graph authorizations. OIDC is used to check on the user granting the access if authentication comes through then the OAuth2 grants access for the application. During the process, the credentials aren’t revealed to the application.

The URL contains “key parameters” that explain how targets could be tricked into granting permissions to rogue applications on their account. Key parameters signify the kind of access that is being demanded by the Microsoft Identity Platform. In the above-mentioned attack, the request included the ID token and authentication code, mentioned sources.

If the target signs in on the SharePoint link that was delivered via the email they’ll be providing the above-mentioned permissions. If the target doesn’t do so, it will be the job of the domain administrators to handle any dubious activities.

This phishing campaign is just an example of how these attack mechanisms have evolved over the years, to such an extent that they could now try to extort sensitive data out of people seemingly by tricking them into providing permissions without an inkling of an idea of what is actually up.

The lifespan of Phishing Attacks Recorded a Tremendous Growth in H2 2019 – Disposable mail news

Phishing attacks recorded a remarkable surge in H2 2019, the growth has been alarming with the number of phishing websites blockages soaring by 230 percent per year. Earlier, phishers would terminate the fraudulent campaign once their webpages were blocked, however, now they are immediately mobilizing the phishing attack onto other brands. It serves as the main reason as to why the number grew so rampantly.

As the lifespan of phishing attacks increased tremendously, attackers became specific about their target pool and have increasingly targeted online services and cloud storage providers, the primary reason being the huge chunks of sensitive data stored in them that can be downloaded by the attackers to later threaten the victims for a ransom.

Turning towards a diligent attacking method, phishers have improved upon the ways they choose their campaigns and targets – preferring quantity over quality. Client software, e-commerce, online streaming, and delivery services were some online services that contributed to 29.3 percent of the phishers’ targets, cloud storages amounted to 25.4 percent while financial organizations made for a total of 17.6 percent, as per the statistics for the last year.

While spotting and preventing the distribution of threats online, a total of 8,506 phishing web resources were blocked by Group-IB’s Computer Emergency Response Team (CERT-GIB).

While providing insights on the matter to Help Net Security, Yaroslav Kargalev, CERT-GIB deputy head said, “Several years ago, creators of phishing pages were likely to have some technical background, they created phishing pages, putting much effort into the launch of their campaigns, preventing them from being detected and relentlessly supporting their sustainability….”

“This industry has changed its face — those pioneers no longer create phishing pages, they create tools for operators of web phishing campaigns who do not necessarily have any programming skills, and last year became the culmination of this trend. Since this new generation of phishers is not that experienced in maintaining the web resources viable, the phishing community’s focus has shifted toward the number of scam resources,” he added.

Banking Trojans and cryptocurrency projects have seen a steep decline in their preference amongst cybercriminals. As the functionality of backdoors has continued to expand, spyware and backdoors have stolen the show to reach the number one spot in the popularity rankings with a whopping 35 percent share.

Hackers Exploit Ad Networks to Launch Phishing Attacks against Android Users – Disposable mail news


The hackers are exploiting mobile ad networks that take the android users to malicious websites. After this, hackers can either steal personal user information or attack the victim’s Android device with spams.

The Google play store has more than 400 apps that come with ads as a means to generate money for app developers. But recently, the hackers are exploiting these ad networks with the help of an SDK (Software Development Kit). The SDKs help app developers earn money, and the hackers are inserting code to attack the ad network.

According to the research done by Wandera, which is a mobile security firm, the hackers send domain and URLs to the users via the ads. The distribution systems are called Startapp, that allows the hackers to swamp the android device with spams and malicious websites. Startapp isn’t responsible for any of the malicious content distributed. However, it is funded by a few agencies that distribute its malicious content. Startapp hasn’t responded to the questions of its involvement in this cyberattack. “Our researchers wanted to explore a service that wasn’t associated with a single well-known advertiser, such as Google or Facebook, so they took a closer look at the framework from StartApp, which would presumably provide app developers with ads from a wider variety of advertising networks,” says Wandera’ research report.

It also says that more than 90% of the distributed through the Startapp framework originate from a single ad provider.  Wandera, however, didn’t identify the provider’s name, but Cyberscoop has identified it as “AdSalsa.” AdSalsa is a digital marketing firm that operates from Spain and is responsible for ads that direct users to these malicious websites.

“We help app publishers and developers turn their apps into successful businesses by using advanced data insights to identify relevant campaigns across direct and programmatic channels for each publisher’s unique users. Over 400,000 apps have already integrated our lightweight, easy to incorporate advertising SDK. When combined with our mediation options, you can begin earning revenue from your apps in minutes,” says StartApp on its website.  Experts at Wandera found 700 apps on Google play store using StartApp’s SDK feature. Google, however, has removed 47% of these SDKs, according to Wandera.

The exploitation of this advertising, which has now become malvertising, is creating problems for the app developers to secure their apps.

Coronovirus Themed Phishing Attacks Continue to Rise – Disposable mail news

New data by researchers has demonstrated that cybercriminals are preying on people’s concerns regarding the COVID-19 pandemic and carrying out sophisticated phishing, malware and email attacks. The sudden upsurge in the related attacks imply that attackers were quick to adapt to the new global health crisis environment and exploit it in their favor.

As per Barracuda Networks, an American IT security company, the number of email attacks associated with the new Coronavirus has seen a steady surge since January, the type of attack has recorded a 667% spike by the end of February. As per the data, January recorded a total of 137 attacks only, while in the month of February the number spiked to a whopping 1,188 and between March 1st to 23rd, there were as many as 9,116 email attacks in the regard.

Another notable kind of attack is the one where victims are receiving malicious emails with the promises of offering financial relief during the COVID-19 pandemic, researchers warned. Users are being tricked into believing that they will be receiving payments from global institutions, businesses and governments working with a common objective of providing economic aid to common people during the ongoing pandemic, as soon as the user clicks on the links or proceed to download files, the attacker gets illicit access to his credentials, card data, and other sensitive information.

One such campaign is found to be specifically attacking U.S. healthcare, IT sector and higher-education organizations, the emails sent in relation to this campaign contain a message titled “General Payroll!”

“The Trump administration is considering sending most American adults a check for $1,000 as part of the efforts to stimulate the economy and help workers whose jobs have been disrupted by business closures because of the pandemic,” it says.

“All staff/faculty & employee include students are expected to verify their email account for new payroll directory and adjustment for the month of March benefit payment.” The message further reads.

Users receiving the email are asked to access a malicious link that will direct them to a phishing page in order to verify their email account, they will be required to enter their usernames, email addresses, and passwords linked with their employee benefits. By doing so, the user will provide his personal data to the page controlled by the attackers.

“The ongoing shift to coronavirus-themed messages and campaigns is truly social engineering at scale, and these recent payment-related lures underscore that threat actors are paying attention to new developments,” researchers told.

Betting and Gambling Websites under Cyberattack from Chinese Hackers – Disposable mail news


Since last year’s summers, Chinese hackers have been targeting South Asian companies that own online gambling and betting websites.
The gambling companies in South Asia have confirmed the hacks, whereas rumors of cyberattacks on betting websites have also emerged from Europe, and the Middle East, however, the rumors are yet to confirm, says the reports of cybersecurity group Trend Micro and Talent-Jump.
Cybersecurity experts claim that no money was stolen in these hacks against the gambling websites. However, hackers have stolen source codes and databases. The motive of the attack was not a cybercrime, but rather espionage intended attack to gain intelligence.

According to the experts, a group named ‘DRBControl‘ is responsible for the cyberattack.
According to the reports of Trend Micro, the hacking techniques used in this particular cyberattack incident is similar to methods done by Emissary Panda and Winnti. All of these hacking groups are from China that has launched cyberattack campaigns in the benefits of the Chinese state.
As of now, it is not confirmed whether DRBControl is launching these cyberattacks in the interests of the Chinese government. According to the cybersecurity group FireEye, not all the attacks have been state-sponsored, as a side business, hackers have been launching these attacks for profits and money.

How did the attacks happen?


The techniques used by DRBControl is not very uncommon or unique. Rather, the attacking techniques used to target victims and steal their data were pretty simple. The hackers send phishing emails that contain backdoor entries malware, and if the user is lured into opening these mails, the system gets infected with backdoor Trojans.
However, these backdoor Trojans are not the same as the others.

This kind of Trojan relies on Dropbox file service for hosting and sharing to be used as C&C (control-and-command), to store stolen data and 2nd level payloads. Hence the name, DropBox Control.
The Chinese hackers usually use the backdoor Trojans to install other hacking malware and tools so that they can roam through the network and trace the path to the source codes and databases to steal the user data.

A nonprofit organization committed towards competitive athletes with intellectual inabilities, The Special Olympics of New York as of late at the Christmas holidays had their email server hacked which was later utilized to dispatch a phishing campaign against past donors.

Promptly as the issue surfaced a notification was sent by the nonprofit to reveal the security episode to the people influenced, asking the donors to dismiss the last message received and clarifying that the hack just affected the “communications system” that stores just contact information and no financial information.

The phishing messages conveyed by the attackers were ‘camouflaged’ as an alert of an approaching donation transaction that would consequently debit $1, 942, 49 from the target’s account within two hours.

Utilizing such a brief span outline enabled the phishers to initiate a ‘sense of urgency’ intended to make the Special Olympics NY donors click on one of the two installed hyperlinks, links that would, as far as anyone knows, divert them to a PDF rendition of the transaction statement.

The phishing email used a Constant Contact tracking URL that redirected to the attackers’ landing page. This page has since been brought down, however, it was in all likelihood used to steal the donors’ credit card subtleties.

“Please review and confirm that all is correct if you have any questions, please find my office ext number in the statement and call me back,” the phishing emails said. “It is not a mistake, I verified all twice. Thank you, have a great weekend.”

Shockingly so, this isn’t the first, historically speaking, episode where such a ‘mishappening’ was recorded, as the Tokyo 2020 Summer Olympics staff additionally gave an admonition cautioning of a phishing campaign that conveyed emails intended to look like they had originated from the Tokyo Organizing Committee of the Olympic and Paralympic Games (Tokyo 2020).

And additionally said that the malignant emails probably diverted the beneficiaries to landing phishing sites or tainted the victim’s PCs with malware whenever opened.
