Microsoft has issued a warning regarding a new campaign that distributes malicious Visual Basic Script (VBS) files via WhatsApp messages, marking a concerning development in the realm of cybersecurity threats.

This campaign, which began in late February 2026, utilizes these scripts to initiate a multi-stage infection chain, ultimately aiming to establish persistence and enable remote access to compromised systems.

The specifics of the lures used by threat actors to trick users into executing these malicious scripts are currently unknown, adding an element of unpredictability to this threat.

The use of WhatsApp as a delivery mechanism highlights the evolving nature of cyber threats, where attackers are increasingly leveraging popular communication platforms to spread malware.

Microsoft’s warning underscores the importance of vigilance and robust security measures, especially in the face of such sophisticated and socially engineered attacks.

As users, being aware of the potential risks associated with clicking on links or downloading files from unknown sources, even when they appear to come from trusted platforms like WhatsApp, is crucial in mitigating these threats.
