How does CVE-2019-11931 can Compromise with WhatsApp Phone Security?
It has been seen that the smartphones having WhatsApp versions below 2.19.244 are the primary target of these bugs. A double-free bug-like CVE-2019-11932 uses one such loophole to trespass in a user’s phone.
Maximum reports came that the app bug has installed in the form of GIF in the phone. Once it’s installed the users have always found some way or the other their potential information has been compromised with third-party sources. That’s one of the reasons why the users are well informed to avoid replying or clicking unknown GIFs whenever it comes to android phones.
If you’re facing any such GIF video from unknown sources, straightaway deleting the video will always be a smart initiative from your side.
Maximum people get victimize to one such threat because the bug app follows an MPE4 video format. Most of the users click it often unknowingly that they’re downloading a malicious malware in their phones.
The Strategy of the Malware to Pawn the Information in a Smartphone
According to a recent technical write-up shown in Github, we can say that the malware usually gets triggers in two ways.
- First Way
It targets an android device first and then installs a malicious application in it. After that, it generates a GIF file that looks pretty similar to any common GIF video. So that the user can’t doubt it as malware. The moment a user shows interest in downloading the software, paranoid activities start on your smartphone!
Sometimes, it may steal confidential data installed in your phone. At times, it might randomly hunt down the file storage where personalized data and other vital information remain stored. At times it may even silently record the personalized data and pass it over the hackers.
- Second Way
The second strategy of the spyware is, it uses GIF payload in WhatsApp as an attachment through other channels. When the user opens the gallery view in the messaging and chatting application, the accuse GIF file gets parses two times. After it opens a remote shell pre-installed in-app. That leads to a successful RCE in smartphones and the phone becomes a breeding ground for multiple third-party sources.
So, by now it must be easy for the readers to evaluate the vulnerability of one such app if it ever gets install in a smartphone.
How to Avoid This Threat in Your Smartphones?
The first and foremost thing you need to do is check the current version of WhatsApp installed in the phone. According to security researchers, it has been said that since Facebook has taken WhatsApp now. The current WhatsApp version 2.19.244 has evaded such threats suitably.
If the current version of your WhatsApp is not 2.19.244, it’s time for you to update your WhatsApp version. Recently a senior spokesperson from WhatsApp retorted about the issue. The issue is much prone to affect the user who’s sending one such GIF. It has a high chance of affecting the sender’s device.
However, after using the new version of WhatsApp no report has been issued or claimed until now from the user’s side.
