- Datper Malware - APT Group Uses Datper Malware To Launch Cyber Attack on Asia Country

An advanced persistent threat () actor known by several different names such as Tick, Redbaldknight and Bronze Butler carried out a number of 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.

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.

With the recent campaign, the hacker group uses Datper malware written in Delphi, capable of executing shell commands on the victim machine to retrieve hostnames and drive information.

The attackers used compromised Korean laundry website for C2 communication, once the malware is dropped it gathers victim machine, including system information and keyboard layout.

At the time of our investigation the C2 servers are not active, so no other details available, “it is possible the malware samples are being delivered using web-based attacks, such as drive-by downloads or watering hole attacks,” researchers said.

“We confirmed that the actor periodically changed their C2 infrastructure and appears to have a history of identifying and penetrating vulnerable websites located in these countries.”

The same infrastructure found shared between the malware families Datper, xxmm backdoor, and Emdivi. Also, researchers found that the same IP used by Datper and Emdivi malware families.
