An advanced persistent threat (APT) actor group known by several different names such as Tick, Redbaldknight and Bronze Butler carried out a number of cyber attacks targeting East Asia.
The APT group used custom tools and compromised websites for C2 servers, the hacker group primarily targets South Korea and Japan.
Security researchers from Cisco Talos observed the APT group recurring patterns in the actor’s use of infrastructure, from overlaps in hijacked command and control (C2) domains to differing campaign C2s resolving to the same IP.
