Palo Alto Networks Device 42, which is monitoring the activity beneath its constellation-themed moniker Playful Taurus, reported it observed the government domains trying to connect to malware infrastructure previously discovered as associated with the adversary.
Also known by the names APT15, KeChang, NICKEL, and Vixen Panda, the Chinese APT group has a record of cyber espionage campaigns aimed at government and diplomatic entities across North The us, South The usa, Africa, and the Center East at least considering the fact that 2010.
Slovak cybersecurity agency ESET, in June 2021, unpacked the intrusions mounted by hacking crew versus diplomatic entities and telecommunication corporations in Africa and the Center East utilizing a custom made implant identified as Turian.
Then in December 2021, Microsoft introduced the seizure of 42 domains operated by the team in its attacks targeting 29 nations, though pointing out its use of exploits from unpatched programs to compromise internet-going through web applications these as Microsoft Exchange and SharePoint.
