WhatsApp Web also has its risks and here we tell you what to do to keep your data and conversations safe
As we well know, in order to use WhatsApp Web on any computer, it is necessary to scan a QR code with our smartphone, which consists of an image that, when scanned, generates a URL and others that are decrypted by the device that it. The use of QR codes is generally safe, but some “traps” have also been developed so that apps that use this technology as a registration method can be targeted by cyber criminals.
This cyber attack is called QRLjacking and uses social engineering techniques to access all contacts, files and conversations of the victim’s account through tools that capture and store the image of the QR code generated by WhatsApp and generate a new QR code targeting the victim, posing risks to their data.
Beware of your information on WhatsApp Web
When the victim scans the fake code, his session is stored on the criminal’s computer and can use it whenever he wants without the victim being notified by his smartphone. To make sure this isn’t us happens, we give you a few simple steps: To keep your information and conversations safe when using WhatsApp Web, follow these steps:
The first thing to keep in mind is that the QR codes that WhatsApp asks to scan are exclusively and exclusive to login, so if after that another code appears on an ad offering benefits or promotions, or even a validation process, then immediately be suspicious. Any app or company that uses QR codes as a means of authentication will notify its users through their official channels.
Keep in mind that QRLjacking can occur when the cyber criminal is connected to the same network as its victims, so if you are connecting to public or open networks for any reason, avoid sharing sensitive information.
It is also important to be vigilant while browsing the Internet because even when we connect to secure networks, whether they are at home or at work, we should not lower our guard due to the security vulnerabilities that attackers exploit, we avoid risks .
Keep in mind that these types of attacks are usually unresponsive when the victim falls, that is, if using WhatsApp Web scans a QR code that does not provide any action, chances are that this is a cyber attack. To be able to reverse this situation, the most convenient is to access the “WhatsApp Web” option in the app from the smartphone and close all initiated sessions. This will close all active sessions so that attackers immediately lose access.
