Meta, the parent company of Facebook, Instagram, and WhatsApp, is fighting back against two cyber-espionage operations, one of them targeting military and government officials in the Middle East.

In recent months, Meta took down accounts, blocked the groups’ domain infrastructure from being shared on its services, and notified people it believes were targeted by the espionage operations, the company said in its recent quarterly threat report. Meta also shared information about the groups with security researchers and other internet companies, the company said.
