This analysis highlights the evolution of modern malware distribution techniques, blending sophisticated obfuscation with targeted delivery mechanisms to maximize infection success while minimizing detection. This loader operates through a meticulously crafted execution flow that begins with JScript, transitions to PowerShell, and culminates in the delivery of fileless malware. The researchers noted that this location-based payload delivery represents an evolution in targeted malware distribution techniques, allowing threat actors to customize attacks based on geographic considerations. Security professionals are advised to implement robust detection mechanisms focused on identifying suspicious PowerShell execution chains and fileless injection techniques. Cybersecurity researchers have uncovered a sophisticated multi-stage attack chain utilizing JScript to deliver dangerous malware payloads. This code fragment demonstrates how the malware uses PowerShell reflection to dynamically load malicious components while evading detection. Upon execution, the JScript loader creates a PowerShell command by ingeniously reassembling randomly ordered array elements into a coherent script.

The attack, which employs a complex obfuscation technique, ultimately delivers either XWorm or Rhadamanthys malware depending on the victim’s geographic location. Victims are targeted with an mshta.exe command that executes obfuscated JScript code, which in turn generates PowerShell commands. This technique allows attackers to bypass traditional security measures by leveraging legitimate Windows components to execute malicious code. With years of experience under his belt in Cyber Security, he is covering Cyber Security News, technology and other news. The malware implements thorough anti-forensic measures, including terminating competing processes and removing potential evidence files from various system directories. Non-US victims are infected with Rhadamanthys, a sophisticated C++ info-stealer that employs AI-powered image recognition to identify cryptocurrency wallet seed phrases.
