The FBI, the Cybersecurity and Infrastructure Security Agency (CISA) and the Treasury Department on Monday warned of "malicious" cyber threats from North Korean state-sponsored actors seeking to exploit "vulnerabilities cryptocurrency technology firms, gaming companies, and exchanges" in the United States in an effort to "generate and launder funds" to support the North Korean regime.

In a joint advisory Monday, the agencies sought to "highlight the cyber threat associated with cryptocurrency thefts and tactics used by a North Korean state-sponsored advanced persistent threat group since at least 2020."

The advisory states that the group is "commonly tracked" by the cybersecurity industry as "Lazarus Group, APT38, BlueNoroff, and Stardust Chollima."

"The U.S. government has observed North Korean cyber actors 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 large amounts of cryptocurrency or valuable non-fungible tokens (NFTs)," the advisory states.

The agencies warned that the malicious cyber activity involves "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," the agencies warned.  "These activities enable additional follow-on activities that initiate fraudulent blockchain transactions."

According to the government, as of April 2022, North Korea’s Lazarus Group actors have "targeted various firms, entities, and exchanges in the blockchain and cryptocurrency industry using spearphishing campaigns and malware to steal cryptocurrency."

"These actors will likely continue exploiting vulnerabilities of cryptocurrency technology firms, gaming companies, and exchanges to generate and launder funds to support the North Korean regime," the agencies warned.

The advisory comes after the United States, last month, linked the Lazarus Group to a cryptocurrency heist of more than $620 million earlier this year.

The Treasury Department added the notorious Lazarus Group to its sanctions list last month and identified a series of prohibited transactions it was tied to. 

"Identification of the wallet will make clear to other [virtual crime] actors, that by transacting with it, they risk exposure to U.S. sanctions," the Treasury Department said in a statement to Fox News Digital. "This demonstrates Treasury’s commitment to use all available authorities to disrupt malicious cyber actors and block ill-gotten criminal proceeds."

This is not the first time the Lazarus Group is believed to have been involved in a major breach—the group was sanctioned by the Treasury Department in 2019 for its alleged involvement in the 2014 Sony Pictures hack, and claimed it was under the control of North Korea’s primary intelligence agency, the Reconnaissance General Bureau (RGB).

Meanwhile, a 2019 United Nations report found that North Korea had stolen a whopping $2 billion for its weapons of mass destruction programs by relying on "widespread and increasingly sophisticated" cyberattack schemes.
