Malicious video files target WhatsApp users

WhatsApp has been hit by a security vulnerability that allows hackers to target victims using a specially-crafted MP4 file.

This new vulnerability comes days after an Israeli software Pegasus exploited WhatsApp’s video calling system to snoop on 1,400 selected users globally.
