How hackers crash WhatsApp groups by just sending one message! Very dangerous hack/bug, in this blog post we are going to discuss this new bug. we will discuss everything about it just read this full blog post
How its worked previously!
To create a malicious message that would impact a WhatsApp the bad actor would need to be a member of the target group (WhatsApp allows up to 256 users per group From there, the bad actor would need to use their web browser's debugging tool to edit specific message parameters and send the edited text to the group.
This edited message would cause a crash loop for group members, denying users access to all WhatsApp functions until they reinstall WhatsApp and delete the group with the malicious message. Check Point Research disclosed its findings to the WhatsApp bug bounty program in August this year. WhatsApp acknowledged the findings and developed a fix to resolve the issue which users should manually apply on their devices.
"WhatsApp responded quickly and responsibly to deploy the mitigation against exploitation of this vulnerability," said Vanunu.
The Check Point Research team found the vulnerability by inspecting the communications between WhatsApp and WhatsApp Web, the web version of the app which mirrors all messages sent and received from the user's phone. This enabled researchers to see the parameters used for WhatsApp communications and manipulate them.
The new research builds on the 'FakesApp' flaws discovered by Check Point Research, which allowed group chat messages to be edited to spread fake news. WhatsApp has also released a new beta that brings in several tweaks, including a fix for a serious bug that caused the last version of WhatsApp beta for Android to crash for many users.
