Cybersecurity researchers have offered a closer look at the RokRAT remote access trojan that’s employed by the North Korean state-sponsored actor known as ScarCruft.
“RokRAT is a sophisticated remote access trojan (RAT) that has been observed as a critical component within the attack chain, enabling the threat actors to gain unauthorized access, exfiltrate sensitive information, and potentially maintain persistent control over compromised systems,” ThreatMon said.
ScarCruft, active since at least 2012, is a cyber espionage group that operates on behalf of the North Korean government, exclusively focusing on targets in its southern counterpart.
The group is believed to be a subordinate element within North Korea’s Ministry of State Security (MSS). Attack chains mounted by the group have leaned heavily on social engineering to spear-phish victims and deliver payloads onto target networks.
Recent spear-phishing attacks, as evidenced by the AhnLab Security Emergency response Center (ASEC) and Check Point, have used LNK files to trigger multi-stage infection sequences that eventually result in the deployment of the RokRAT malware.
RokRAT allows the adversary to harvest system metadata, take screenshots, execute arbitrary commands received from a remote server, enumerate directories, and exfiltrate files of interest.
The development comes as ASEC disclosed a ScarCruft attack that leverages a Windows executable masquerading as a Hangul document to drop malware that is configured to contact an external URL every 60 minutes.
