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. ...

Hackers Using Advanced MFA-Bypassing Techniques to Gain Access to User Accounts

Ravi Jain
How cybercriminals are employing sophisticated techniques to bypass multi-factor authentication (MFA), a security measure designed to prevent unauthorized account access. These methods exploit vulnerabilities in the authentication process itself, such as manipulating session tokens and utilizing transparent phishing, rather than directly targeting passwords or one-time codes. The consequences of successful MFA bypass include minimal forensic evidence and difficulty in detection, potentially leading to data theft. To defend against these evolving threats, the text recommends strategies like continuous MFA validation, the use of cryptographically signed tokens, and the adoption of phishing-resistant authentication method. ...
