WhatsApp users are in danger if they have version v2.21.22.7

We always recommend updating applications to prevent malware from affecting our security. Right now, biosafety experts are warning users of WhatsApp that have the patch v2.21.22.7, because it has a bug that causes corruption of the internal memory of the smartphone.

The National Institute of Cybersecurity of Spain (INCIBE) alerted users to WhatsApp of a serious vulnerability detected in the aforementioned version, which is available both in the standard edition of the application and in WhatsApp Busines. If you do not update the app, you will be at risk of “Receive a malicious image that may cause device memory corruption (buffer overflow)”.

The fault is caused by Image Blurring Handler. What the hacker does is “Create and send a malicious image that, due to lack of verification of the blur code when it is received, can cause writing out of limits (overflow) of the buffer or corruption of the memory of the device”, which would affect the availability, confidentiality and integrity of the data and programs stored on the computer.

Whether or not you have this version, we recommend updating the WhatsApp ASAP to avoid being a victim of hackers.

If you have Android, open the Google Play Store, then touch the Menu icon> My apps and games. There you will see the UPDATE button next to WhatsApp Messenger.

In the case of ios, open the App Store, then tap Updates. There click on UPDATE next to WhatsApp Messenger.
