OAuth Attacks Target Microsoft 365 & GitHub

OAuth Attacks Target Microsoft 365, GitHub: A Deep Dive into the Latest Threats

Ravi Jain
Ongoing cyberattacks are exploiting the OAuth protocol on platforms like Microsoft 365 and GitHub. Cybercriminals are using deceptive tactics with fake applications mimicking trusted brands such as Adobe, DocuSign, and even GitHub itself. These malicious apps trick users into granting broad permissions, enabling attackers to gain persistent access and potentially redirect victims to phishing sites or deploy further attacks, targeting sectors with sensitive data. Organizations are advised to implement strong security measures, including limiting app permissions, employing conditional access policies, regularly auditing applications, and educating users to recognize these evolving threats. ...

MalDoc in PDF: How Attackers Use Word Files in PDFs to Evade Security

Ravi Jain
Cyberattack method called MalDoc in PDF, where malicious Word files are concealed within seemingly harmless PDF documents to bypass security defenses. This technique exploits the dual nature of the file; when opened with a PDF reader, it appears benign, but opening it with Microsoft Word triggers embedded malicious macros that can compromise systems. Traditional security measures often fail to detect this threat because they primarily analyze the PDF structure and may overlook the embedded Word components. The document outlines how this attack works, its dangers, methods for detection using tools like OLEVBA and YARA rules, and preventative measures such as disabling automatic macros and strengthening email security. ...
