A cybersecurity expert discovered a vulnerability in Messenger.
Facebook announced, on Saturday, that it had fixed a “fatal error” in its “Messenger” application, after several espionage and hacking incidents were reported, according to ZDnet reports.
The source said that a cybersecurity expert discovered a security vulnerability that “hackers” used to spy on users using phones running the Android operating system.
The expert informed the company “Facebook” last month about this flaw, but it was not corrected until this week.
Natalie Silvanovic, a researcher in the “Project Zero” safety team, said in a tweet on her Twitter account that Facebook gave her a $ 60,000 reward after she helped report the bug.
To trap the victim, the intruder must initiate a voice call that includes invisible code (within the communication) designed specifically for hacking. Then he can listen to the victim’s voice even if he does not answer the call.
“This report is among the top three rewards we have for errors and loopholes,” Facebook said in a statement, reflecting its potentially significant impact.
In 2018, Silvanovic discovered a flaw in WhatsApp, allowing attackers to hack any phone after the user answers a video call.
