Alert: VBS files in WhatsApp can take control of your PC

Published on June 25, 2026 | Translated from Spanish

A new malware campaign is using WhatsApp to distribute VBS files disguised as invoices or work documents. When opened on Windows, these scripts execute commands that allow attackers to take remote control of the computer. The recommendation for users is clear: do not open files with the VBS extension, even if they come from a known contact. Protecting your personal information depends on not executing these suspicious files.

How the attack with VBS scripts on Windows operates 🛡️

The attack mechanism is simple but effective. Cybercriminals send a file with the .vbs extension, which Windows executes via Windows Script Host. When opened, the script downloads and installs a payload that establishes a remote connection with the attacker, allowing them to steal data, install more malware, or spy on the user's activity. These files often have names like invoice_2025.vbs or urgent_document.vbs to deceive the victim. Prevention depends on distrusting any unexpected attached files.

The surprise gift you didn't ask for on WhatsApp 🎁

Because nothing says I love you like a VBS file disguised as an invoice. It's like a friend giving you a box that turns out to be a black hole for your PC. Opening it is like inviting a stranger into your home and handing them the keys to the secret closet. The irony is that the known contact who sent it to you was probably already a victim of the same trick. So you know: if you receive a strange file, better pretend you didn't see it and move on with your digital life.
