“This is the most extensive operation we have ever reported by a Chinese APT group,” the cyber researchers at Check Point told me, warning just how “targeted and sophisticated” this five-year campaign had been. Multiple overseas governments have been compromised by this threat group’s cyber weapons, and those government systems have been used to attack other countries.
The military espionage group’s tactics, described by Check Point as “very dangerous,” involved hijacking diplomatic communication channels to target specific computers in particular ministries. The malware-laced communications might be sent from an overseas embassy to ministries in its home country, or to government entities in its host country. “The group has introduced a new cyber weapon crafted to gather intelligence on a wide scale, but also to follow intelligence officers directives to look for a specific filename on a specific machine.”
