Researchers detail security flaw that allowed hackers to crash WhatsApp and permanently delete contents of group chats - and urge users to update the app to protect against attacks.
WhatsApp has fixed a security flaw that could have allowed cyber attackers to repeatedly crash the messaging application for all members of group chat, which could only be fixed by forcing the complete uninstall and reinstall of the app.
But even once the application is restored, users aren't able to return to the group, causing the loss of all of the messages and media exchanged in the chat.
The vulnerability in the chat application used by over 1.5 billion people has been
uncovered by cybersecurity researchers at Check Point who worked with Facebook-owned WhatsApp to ensure it can't be exploited by malicious attackers.
