WhatsApp is the most used app when it comes to messaging services.

All texts, videos, photos as well as audio recordings come through this application, and there is no doubt that it can at times get pretty much inconveniencing to handle all of these messages on your phone.

So, why not read and respond to your WhatsApp messages from your PC, especially if you are the kind that spends loads of hours working on a PC? Well, if you do decide to move over to this WhatsApp Web client on your desktop, you will be joining 200 million other users of the web client. This client brings the WhatsApp messaging experience to the desktops, which means a larger screen and better typing via a real keyboard.

However, there is something you need to know before moving on to WhatsApp Web (for newbies). An Israeli-based security firm known as Check Point has discovered a bug in this web application that might just put you and your data at risk. This flaw allows hackers to distribute malware to your PC through this WhatsApp Web client and in the end; you might lose control of your system to a stranger.

How WhatsApp Web works

WhatsApp Web is a web-based version of the phone app that synchronizes your phone and PC in a bid to mirror all the messages sent via the app to your PC’s web browser. With this application, you can see all your messages on your PC, respond to them as well as do a bunch of other things, for instance, updating your WhatsApp status.

WhatsApp has over 900 million users and of these, about 200 million are already using WhatsApp Web. Just recently, iPhone users were added to the platform after WhatsApp initially claiming that Apple had some platform limitations that prevented the application from working on iOS devices.

In the security firm’s report, the company said that it had found a vulnerability that allows hackers to trick WhatsApp Web users into executing malicious code on their PCs. To do this, a hacker only needs the phone number associated with the victim’s WhatsApp account, and that’s it. The hacker will then send a message in theform of a vCard and it there is the malicious code.

Once an innocent user opens the message to reveal the contact in the vCard, the executable file within it will start distributing bots and other malware on your PC. According to Check Point, this flaw can grant hackers full control of your system. In some cases, victims may be forced to part with some cash via certain online means before they can regain access to their PCs or maybe get their data back.

Since the security, breach was confirmed to WhatsApp by Check Point, the Facebook-owned application has moved in swiftly with an update to the Web client, which is available free download right away. So, to ensure that you stay safe, upgrade to the latest WhatsApp Web now by simply clearing your browser’s cache and history, then follow it by logging into the app once again via the usual scanning of the QR code.
