Microsoft has issued a warning about a new campaign that uses WhatsApp messages to distribute malicious Visual Basic Script (VBS) files, marking a new tactic in the ongoing battle against cyber threats.
According to the details, this campaign started in late February 2026 and involves the use of VBS scripts to initiate a multi-stage infection chain. This complex process enables the attackers to establish persistence and gain remote access to the compromised systems.
The exact method used by the threat actors to lure users into executing these malicious scripts is currently unknown, highlighting the need for increased vigilance among users. The use of social engineering tactics, such as fake messages or enticing links, is a common practice in such campaigns.
This VBS malware campaign underscores the importance of being cautious when interacting with messages or files received from unknown sources, especially those delivered through popular messaging platforms like WhatsApp. Users are advised to be on the lookout for suspicious activities and to keep their systems and software up to date to mitigate potential risks.
Microsoft’s warning serves as a reminder of the evolving nature of cyber threats and the need for continuous awareness and education. As new vulnerabilities like CVE-2023-21768 and others are discovered, and with the existence of threats such as the UAC bypass vulnerability, staying informed is key to protecting against these emerging threats.
For users and organizations looking to protect themselves from such threats, it is essential to implement robust security measures, including regular updates, the use of antivirus software, and educating users about the dangers of social engineering attacks and the importance of safe computing practices.
