Coverage Added for US-CERT (AA22-108A) – TraderTraitor

On April 18th, Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), and the U.S. Treasury Department (Treasury) issued a joint advisory highlighting the cyber threat associated with a North Korean APT group involved in cryptocurrency thefts since 2020. Additional details about this threat and the associated tactics, techniques, and procedures (TTPs) are available in US-CERT Alert (AA22-108A) TraderTraitor: North Korean State-Sponsored APT Targets Blockchain Companies.

Stealing Cryptocurrency to Fund the North Korean Regime

The North Korean APT group responsible for these attacks is the Lazarus group (also known as APT 38, BlueNoroff, and Stardust Chollima). As of April 2022, the U.S. government observed this APT group targeting a variety of organizations in the blockchain technology and cryptocurrency industry, including cryptocurrency exchanges, decentralized finance (DeFi) protocols, play-to-earn cryptocurrency video games, cryptocurrency trading companies, venture capital funds investing in cryptocurrency, and individual holders of substantial amounts of cryptocurrency or valuable non-fungible tokens (NFTs).  

Attacks involving malware-laced cryptocurrency applications referred to as TraderTraitor involves the social engineering of victims using a variety of communication platforms to encourage individuals to download trojanized cryptocurrency applications on Windows or macOS operating systems. The cyber actors then use the applications to gain access to the victim’s computer, propagate malware across the victim’s network environment, and steal private keys or exploit other security gaps. These activities enable additional follow-on activities that initiate fraudulent blockchain transactions.

These actors will likely continue exploiting the vulnerabilities of cryptocurrency technology firms, gaming companies, and exchanges to generate and launder funds to support the North Korean regime. Last year, the FBI, CISA, and US Department of Treasury also shared information on malicious and fake crypto-trading applications injected with AppleJeus malware used by Lazarus to steal cryptocurrency from individuals and companies worldwide.
