Fake Invoice Leads to Backdoor.XWorm Discovery

Source: Malware Bytes

An email disguised as an invoice contained a Visual Basic Script attachment that could install Backdoor.XWorm, a sophisticated remote-access Trojan (RAT). Despite its age, the .vbs file is a reminder of how simple tactics can evolve into serious threats. Opening the attachment could have allowed attackers to steal personal data, record keystrokes, and even install ransomware without detection.

The presence of a .vbs attachment is a peculiar red flag in modern business communications where such files are rarely used anymore. Most companies block these types of files, making their appearance suspicious. This tactic demonstrates attackers’ growing innovation in bypassing security filters, using retro formats alongside advanced techniques to exploit unsuspecting users. Understanding these threats and maintaining vigilance can help organizations protect themselves from evolving cybersecurity risks.
