The WhatsApp Web application had a nice promotion and a relatively short virtual existence, before it has experienced a malware-related trouble. It seems that the invaluable vCard feature can be a source of great trouble for millions of users of this extremely popular app.

Why? Well, the hackers have found a way to install both malware and ransomware in a tiny vCard file. To make the things even worse for WhatsApp users these malicious visitors do not have to ask your permission, when it comes to installation in your device.

The good news is that WhatsApp team was prompt in its response, and you can rest assured that this security flaw is already being fixed. On the other side, our hats off to the busy little bees, who have located and identified this cyber-trouble. We sure hope, they will get something in return.

From what we know, WhatsApp has not been involved in bug bounty reward systems, so far. Yet, its new owner Facebook is always interested for security improvements, and notably very generous in this field. Therefore, the Check Point team could get a reward for its efforts. Right?
