WhatsApp is a very secure application usually. Most faults that are detected are not both the application and the people who use them: scams through fraudulent messages, theft of data using third-party applications, etcetera.
However, on this occasion, a failure of the application has been discovered that could expose the private data of a user, among which the Chats of the APP would include.
The discovered failure would allow to exploit the sending of images to block the phone and, in some cases, modify such an image to be able to access the phone's memory.
The modifications are made with an AFL Fuzzer, which changes the files to be able to hide additional information on them and thus send malicious code that violates whatsapp safety and devices from which it is executed.
The ruling was notified to whatsapp on November 10 and the company has resolved it in the latest updates of the APP. Therefore, it is recommended to update all users as soon as possible to be protected from this ruling.Updated Date: 05 September 2021, 04:01
