US Sanctions Target North Korean IT Network Exploiting Crypto Firms
In a significant move to curb cyber threats, US Treasury officials have imposed sanctions on a North Korea-backed IT workforce network. This network has been involved in targeting cryptocurrency companies along with other tech firms. With these sanctions, two individuals and four entities find themselves cut off from the US financial system, marking a decisive step in countering illicit operations.
Unveiling Covert Actions
As per the Office of Foreign Assets Control (OFAC), these sanctions specifically target Song Kum Hyok, a North Korean operator accused of stealing US citizens’ data to fabricate false identities. This maneuver aims to prevent the misuse of stolen identities and crypto theft that finances North Korea’s missile programs, shifting from overt hacking to clandestine operations.

Michael Faulkender, Deputy Secretary of the Treasury, emphasized the importance of these measures in dismantling networks that exploit fraudulent identities for illicit gains. The DPRK’s IT worker schemes are a crucial financial source for their weapons of mass destruction and ballistic missile programs.
The Network’s Modus Operandi
Song Kum Hyok allegedly supplied these fabricated identities to IT professionals who then applied to US-based companies. Another key figure is Gayk Asatryan, a Russian national who, in 2024, entered long-term agreements with North Korean trading firms to hire numerous North Korean developers. As a result, all US assets linked to these individuals and the four sanctioned Russian entities are frozen, effectively barring any American financial dealings with them.
Subterfuge and Crypto Funding
The North Korean IT workforce, primarily stationed in China and Russia, is reportedly in the thousands. These workers seek employment in wealthier nations through conventional and specialized recruitment platforms. The ultimate goal is to infiltrate target companies, thereby generating funds for ballistic missile research, a strategy that diffuses risk and complicates detection compared to singular large-scale attacks.
Shifting North Korean Strategies
Recent research from Google highlights the global reach of these deceptive operations. While dramatic hacks continue to capture media attention, state-affiliated groups increasingly rely on subterfuge. This involves data theft and masquerading as legitimate employees rather than directly breaching systems, a method that is subtler, more cost-effective, and can persist undetected for extended periods.
Escalating Crypto Losses
According to TRM Labs, a blockchain intelligence firm, North Korean-linked actors were responsible for approximately $1.6 billion of the $2.1 billion in crypto thefts across 75 incidents in the first six months of 2025. This significant portion indicates an evolving strategy where false-identity worker schemes are becoming a more prevalent source of revenue compared to major exchange breaches.
