WhatsApp has fixed a dangerous flaw which would have allowed malicious hackers to take over the PCs of Whatsapp Web users, which of course include Windows Phone users.
The flaw, discovered by Checkpoint security researchers, would have allowed hackers to take over a PC by simply sending a specially crafted vCard. Hackers would simply need to know user’s phone number to launch the attack, which could have affected as many as 200 million WhatsApp Web users.
The contents of the malware included ransomware, bots, remote access tools (RATS) and other malicious code.
Fortunately WhatsApp has rolled out a fix for the issue, with versions of WhatsApp Web 0.1.4481 and over no longer vulnerable.
“Thankfully, WhatsApp responded quickly and responsibly to deploy an initial mitigation against exploitation of this issue in all web clients, pending an update of the WhatsApp client,” wrote Oded Vanunu, security research group manager at Check Point.
WhatsApp Web support came to Windows Phone in January 2015, significantly months before it arrived on iOS.
