A Pakistani hacking group has targeted Facebook users connected to the previous Afghan government, military, and law enforcement agencies in Kabul with attacks focused on cyberespionage, the social media company recently said.

The hacking group, known as SideCopy, ramped up a “well-resourced and persistent” cyberespionage operation targeting members of the former Afghan government between April and August, Facebook said in a blog post. The group’s attacks included links to malicious websites hosting malware, said Facebook, which recently changed its name to Meta.
