Lazarus Group, also known as APT38, Dark Seoul, Hidden Cobra, and Zinc, has garnered a reputation as a highly-qualified and well-funded state-sponsored cluster of criminal hackers, wreaking havoc since 2009.
In the most recent campaign, Lazarus deployed novel MagicRAT malware after exploiting vulnerabilities in VMWare Horizon platforms, such as a high-profile Log4j flaw. The notorious APT aimed this series of attacks at a number of energy companies in the U.S., Japan, and Canada.

Cisco Talos released an overview of the new malicious campaign launched by North Korea’s Lazarus Group. Adversaries have introduced a new bespoke implant – a remote access trojan written in C++. The piece of malware, dubbed MagicRAT, performs system reconnaissance, allows to establish persistence by scheduled task creation, also enabling its operators to run arbitrary code and modify files. Additionally, the new RAT fetches additional payloads. According to the research data, threat actors use MagicRAT samples along with other custom-built RATs, such as TigerRAT. The studied examples were programmed with Qt Framework to complicate human analysis.
Based on observed attacks and news reports, we may derive that this North Korean nation-backed collective is expanding its reach with greater reliance upon different tools and techniques, regularly stirring up troubles for SOC professionals.
