Security researchers discovered that sending a specially crafted, 2,000-character message could force the recipient's WhatsApp application to crash completely. The worst part was that the app would crash each time the victim tried to reopen the conversation, forcing them to delete the entire chat history to restore functionality. For a short, frightening period, any WhatsApp group could be instantly and permanently disrupted by a malicious actor armed with this exploit. The vulnerability successfully crashed all versions of WhatsApp, including 2.11.431 and 2.11.432 , across almost all Android devices. The vulnerability became known in the tech press as the "text of death," a reminder that as apps become more integrated into our social fabric, their flaws can have immediate and disruptive consequences.

You usually need root access or a physical backup file from Google Drive.
