WhatsApp has understood to have fixed a bug in its Android and iOS mobile app that allowed the hackers to let the app crash during incoming video calls.
Facebook-owned WhatsApp, which has over 1.5 billion users, fixed the vulnerability this week. It is yet to be known how many users were affected.
The company is yet to issue a statement on this.
Natalie Silvanovich, a security researcher with Google’s Project Zero security research team, discovered the bug in WhatsApp video call. “This issue can occur when a WhatsApp user accepts a call from a malicious peer,” she said.
Memory corruption bug was found in WhatsApp’s video conferencing implementation.
In the biggest-ever security breach after Cambridge Analytica scandal, Facebook last month admitted that hackers broke into nearly 50 million users’ accounts by stealing their access tokens or digital keys. Facebook security team discovered the security issue on September 25 which was later fixed.
In the Cambridge Analytica scandal, data of nearly 87 million people was breached upon.
