The new threat is reported to trigger a buffer overflow conditions leading to the execution of arbitrary code by the attacker. Also, the exploitation does not require any form of authentication from the victim end. It executes on downloading of a malicious crafted MP4 file on the receiver’s system, which can be sent by anyone who has access to a user’s mobile phone number being used for WhatsApp.

A RCE attack is usually used to run malware on the device, and the attack is used to steal information from the device, without the user knowing.
