Hidden Cobra, also known as Lazarus Group and Guardians of Peace, is a North Korean government-linked threat actor known for its malicious cyber activities. The group has primarily conducted cyberespionage but has also been involved in ransomware activity. The U.S. Government refers to this team's specific subset of activity as BeagleBoyz. Hidden Cobra has used various methods to infect systems, including websites appearing to host legitimate cryptocurrency trading platforms and phishing, social networking, and social engineering techniques. They have also deployed malware such as FALLCHILL and AppleJeus to compromise systems. The group's tactics, techniques, and procedures (TTPs) align with previous operations from 2017, which used defense contractors as lures. In October 2018, the US-CERT released a joint technical alert warning about an ATM cash-out scheme dubbed "FASTCash" being used by Hidden Cobra. By 2020, the group was using the domain mireene.com and its sub-domains for their operations. Indicators from these campaigns pointed to earlier activity from 2017 and 2019 that had been attributed to Hidden Cobra. In 2023, the group, also referred to as Sapphire Sleet, actively conducted espionage operations and destructive attacks in the United Arab Emirates region. Microsoft attributed attacks impacting over 100 devices in countries including Japan, Taiwan, Canada, and the U.S. to the Diamond Sleet (another alias for Hidden Cobra) group. Furthermore, the group continued its Operation Dream Job campaign with new intrusions leveraging trojanized Virtual Network Computing apps targeted at defense industry and nuclear engineers.
