A recent report revealed that WhatsApp discovered an advanced security flaw threatening iPhone and MacBook devices, according to Reuters.

Donsha Sirbhiel, head of the security lab at Amnesty International, explained that the flaw was exploited in cyberattacks targeting members of civil groups in various regions worldwide.

Meta confirmed that the flaw was fixed through an immediate app update. It noted that fewer than 200 users were affected by this security vulnerability. The company added that a secondary flaw allowed hackers to control Apple devices, with possible extension to other Meta apps and potentially Android devices.

Sirbhiel stated the attack began at the end of May and lasted for more than 90 days. He pointed out that the flaw is of the “Zero Click” type, meaning it does not require any user interaction to compromise the device.

Investigations have not yet identified the responsible party, according to Meta spokesperson Margarita Franklin, who confirmed the attack was limited in scope and the main perpetrator remains unknown.

This incident follows a history of security attacks on WhatsApp, including the major 2019 Pegasus spyware attack by NSO Group, and another attack targeting Italian activists earlier this year.
