Microsoft has issued a warning regarding a new malicious campaign that uses WhatsApp messages to spread harmful Visual Basic Script (VBS) files to Windows users.
The campaign, which started in late February 2026, utilizes these scripts to initiate a complex infection chain, ultimately establishing persistence and allowing remote access to the compromised systems.
The exact social engineering tactics used by the threat actors to deceive users into executing the malicious VBS files are currently unknown.
However, it is clear that the attackers are exploiting the trust that people have in WhatsApp messages to gain an initial foothold on the target systems, highlighting the need for users to be cautious when interacting with messages from unknown sources.
This type of attack underscores the importance of maintaining robust cybersecurity practices, including being vigilant when receiving unexpected files or links, even from trusted sources.
Microsoft’s warning serves as a reminder for users to remain alert and take necessary precautions to protect themselves from such threats, including keeping their systems and software up to date with the latest security patches and being aware of potential security vulnerabilities like CVEs.
