The Lazarus subgroup TraderTraitor conducted targeted campaigns in 2026 against cryptocurrency-related and non-cryptocurrency entities, including a notable $292 million theft from KelpDAO via LayerZero. A smaller IT services provider in India was also compromised through social engineering involving fake job interview lures with weaponized Terraform projects. Malicious GitHub repositories with typosquatted domains delivered macOS backdoors FLATROOF and ROOFDECK during terraform init execution. These backdoors facilitated reconnaissance, credential theft, and cloud environment escalation. After public disclosure of the LayerZero attack, attackers deployed an updated ROOFDECK backdoor and removed earlier implants, continuing activity until June 2026 before abandoning the intrusion due to low value from the smaller target.
A Lazarus group cyberespionage campaign targeted a Spanish aerospace company by impersonating Meta recruiters on LinkedIn and sending trojanized coding challenges. The attack used spearphishing via LinkedIn Messaging to deliver malicious executables disguised as C++ programming tests. The campaign deployed multiple malware tools including LightlessCan, a new backdoor with enhanced stealth and command capabilities, NickelLoader downloader, and miniBlindingCan variant. DLL side-loading was used to load payloads, and the attack aimed to steal aerospace technology and know-how, aligning with North Korean strategic interests.
The Contagious Trader campaign is a sophisticated malware operation targeting cryptocurrency users, attributed to North Korea with high confidence. It involves malicious cryptocurrency trading bot projects on GitHub that exfiltrate sensitive data and private keys using various techniques, including malicious npm dependencies. The campaign demonstrates overlaps with known North Korean tactics, particularly those of FAMOUS CHOLLIMA, including the use of GitHub, npm, and Vercel infrastructure, Base64-encoded payload URLs, and anonymizing VPNs for npm package publishing. The operation represents a shift in tactics, expanding beyond the previous Contagious Interview campaign to target a broader range of cryptocurrency users.
The Contagious Interview campaign is a coordinated cyber espionage operation by North Korean threat actors, notably linked to the Lazarus group, targeting the cryptocurrency sector. These actors actively monitor cyber threat intelligence platforms such as Validin, VirusTotal, and Maltrail to identify exposed infrastructure and new targets. They prioritize rapid deployment of malicious infrastructure over stealth and use social engineering techniques, including the ClickFix method, to trick victims into executing malware. Between January and March 2025, over 230 victims were engaged, demonstrating the campaign's scale and sophistication. Although no known exploits for CVE-2023-42793 have been observed in the wild, the campaign poses a medium severity threat. European cryptocurrency organizations, especially in countries with significant crypto markets and financial sectors, are at risk. Mitigation requires targeted monitoring of threat intelligence platforms, enhanced user training against social engineering, and rapid incident response capabilities.
