• In this post, we describe our in-depth investigation into a threat actor to which we have assigned the identifier MUT-1244.
• MUT-1224 uses two initial access vectors to compromise their victims, both leveraging the same second-stage payload: a *phishing campaign targeting thousands of academic researchers and a large number of trojanized GitHub repositories, such as proof-of-concept code for exploiting known CVEs.
• Over 390,000 credentials, believed to be for WordPress accounts, have been exfiltrated to the threat actor through the malicious code in the trojanized "yawpp" GitHub project, masquerading as a WordPress credentials checker.
• Hundreds of victims of MUT-1244 were and are still being compromised. Victims are believed to be offensive actors—including pentesters and security researchers, as well as malicious threat actors— and had sensitive data such as SSH private keys and AWS access keys exfiltrated.
• We assess that MUT-1244 has overlap with a campaign tracked in previous research reported on the malicious npm package 0xengine/xmlrpc and the malicious GitHub repository hpc20235/yawpp.

Oasis Security's research team uncovered a critical vulnerability in Microsoft's Multi-Factor Authentication (MFA) implementation, allowing attackers to bypass it and gain unauthorized access to the user’s account, including Outlook emails, OneDrive files, Teams chats, Azure Cloud, and more. Microsoft has more than 400 million paid Office 365 seats, making the consequences of this vulnerability far-reaching.

The bypass was simple: it took around an hour to execute, required no user interaction and did not generate any notification or provide the account holder with any indication of trouble.

The team at CYFIRMA analyzed a malicious Android sample designed to target high-value assets in Southern Asia. This sample, attributed to an unknown threat actor, was generated using the Spynote Remote Administration Tool. While the specifics of the targeted asset remain confidential, it is likely that such a target would attract the interest of APT groups. However, we are restricted from disclosing further details about the actual target and its specific region. For a comprehensive analysis, please refer to the detailed report
