Influenza A virus subtype H5N1 China-linked cyber espionage grouping known every minute Tick was observed using the Datper malware inward a recent campaign, Cisco Talos safety researchers reveal.
Also referred to every minute Redbaldknight together with Bronze Butler, Tick has been launching diverse cyber-attacks against entities inward Republic of Korea together with Nippon over the yesteryear twain of years. The drive Talos analyzed also used compromised websites located inward the 2 countries every minute command together with command (C&C) servers.
Although Tick has been using custom tools inward each campaign, the researchers observed a serial of recurring patterns inward the utilization of infrastructures, such every minute overlaps inward hijacked C&C domains or the utilization of the same IP.
Based on these infrastructure patterns, the experts discovered similarities betwixt the Datper, xxmm backdoor, together with Emdivi malware families that the threat thespian has used inward attacks.
Datper, the malware used inward the drive Talos analyzed, tin execute trounce commands on the victim machine, piece also obtaining hostnames together with drive information. The used infection vector, however, is unknown, Talos says.
The analyzed Datper variant used the compromised website of a legitimate Korean laundry service to host their C&C. Located at whitepia[.]co.kr, the site does non utilization SSL encryption or certificates, which rendered it vulnerable to attacks.
The safety researchers observed other compromised websites every minute good beingness used every minute C&C servers every minute operate of the attack. This led to the hypothesis that the malware could endure delivered via web-based assaults, such every minute drive-by downloads or watering hole attacks.
Talos also discovered hosts that were beingness used every minute C&C servers although they were non connected to compromised websites. This would propose that the hackers initially deployed the C&C infrastructure on legitimately obtained (and potentially purchased) hosts.
“The thespian behind this drive deployed together with managed their C&X infrastructure mainly inward Republic of Korea together with Japan. We confirmed that the thespian periodically changed their C&C infrastructure together with appears to convey a history of identifying together with penetrating vulnerable websites located inward these countries,” Talos says.
Once on the infected machine, Datper would practise a mutex object together with remember several pieces of data from the victim machine, including organisation data together with keyboard layout. Next, the malware attempts to lawsuit an HTTP GET asking to the C&C server (which was unavailable during the investigation).
Some of the compromised websites were also used every minute C&C domains for the xxmm backdoor, also known every minute Murim or Wrim, which was previously associated alongside the threat actor, together with which allows attackers to install additional malicious tools onto the infected machines. The 2 samples also utilization like GET asking URI paths.
