XwormRAT Hackers Leverage Code Injection for Sophisticated Malware Deployment

A sophisticated new distribution method for XwormRAT malware that leverages steganography techniques to hide malicious code within legitimate files.

This discovery highlights the evolving tactics of cybercriminals who are increasingly using advanced obfuscation methods to bypass security detection systems and deceive unsuspecting users.

The latest XwormRAT campaign represents a significant evolution in malware distribution methodology, utilizing steganography to embed malicious code within seemingly innocent image files.

ASEC’s email honeypot system detected this new variant being distributed through phishing emails, where attackers embed malicious scripts directly into legitimate code structures.

The malware initiates its attack chain through VBScript and JavaScript, making detection particularly challenging for both security systems and end users.

The attack sequence begins when victims execute the initial script, which contains an embedded PowerShell component designed to download additional malware from external command-and-control servers.

During execution, the script employs the Replace() function ...
