North Korea Recruits Foreign IT Workers to Infiltrate US Firms

North Korea has increasingly relied on cryptocurrency theft and covert overseas IT workers to generate revenue under international sanctions. The practice poses a particular threat to Web3 companies, whose distributed teams often give remote developers access to source code, multisignature wallets and other sensitive systems. A technically credible applicant using a fabricated identity can therefore become an entry point for espionage, theft or a broader supply-chain attack.

The chief executive of crypto media outlet Unchained recently conducted an undercover remote interview with a suspected North Korean operative posing as a job candidate. The applicant spoke fluently about multisignature wallets and defenses against reentrancy attacks, demonstrating knowledge relevant to blockchain development. But when asked to criticize North Korean leader Kim Jong Un, the candidate became visibly unsettled and abruptly disconnected, exposing a potential weakness in the identity-deception tactics used to penetrate crypto businesses.

North Korea has been accused of dispatching IT workers under stolen or fabricated identities to secure remote jobs abroad, remit salaries to sanctioned state agencies and gain legitimate access to source code and internal systems. The scheme turns recruitment into an insider-security risk, particularly for crypto companies. In a separate case, the U.S. Justice Department said in April 2026 that two American facilitators helped place workers at more than 100 U.S. companies using at least 80 stolen identities, generating more than $5 million for North Korea.

Researchers Mauro Eldritch of BCA LTD, Heiner García of NorthScan and ANY.RUN built a fictitious DeFi startup, Ballena Azul, and hired three people they assessed as suspected Famous Chollima operatives. The findings were presented at DEF CON 34 in Las Vegas in August 2026 and reported on Aug. 11. On their first day, all three profiled assigned virtual machines and checked the apparent location of their connections; investigators also observed AstrillVPN, 2fa.cn and AI job-interview tools. The controlled systems exposed operational behavior and infrastructure without granting access to a real company.

North Korea has long been accused of stealing digital assets to evade international sanctions and generate foreign currency. The Royal United Services Institute, a UK think tank known as RUSI, said Pyongyang is increasingly relying on established criminal networks and scam groups to process illicit proceeds, making the money trail harder to follow and raising sanctions-compliance risks for financial institutions worldwide.

North Korea stole at least $2.8 billion in cryptocurrency during 2024 and 2025, according to RUSI’s latest report. The assets were sold at a discount or blended with proceeds from scams before underground money brokers in Southeast Asia converted them into cash. RUSI said the laundering chain allows Pyongyang to turn stolen crypto into usable funds that can help finance its weapons programs.

North Korea’s central bank oversees currency issuance and state funds, while the Foreign Trade Bank handles foreign payments and currency transactions. The alleged ring included veterans of a military intelligence cyber-operations unit and IT specialists recruited from leading universities. Their suspected use of state-developed hacking expertise against two pillars of the country’s financial system marks an unusual insider breach and exposes vulnerabilities within an apparatus better known for conducting cyber theft abroad.

Daily NK reported on July 24 that North Korea’s security agency raided a Pyongyang safe house on the night of July 12, 2026, arresting alleged ringleaders and IT personnel. Investigators said the group diverted trade funds and foreign currency in small increments, sent them to overseas crypto wallets and used brokers in China to convert the assets into U.S. dollars and Chinese yuan. Authorities did not disclose the amount stolen or the number arrested, but reportedly seized computer equipment worth hundreds of thousands of dollars.

North Korea has long used state-backed hacking groups to target cryptocurrency exchanges and related services. Blockchain security firm CertiK said the country has “industrialized” such theft, turning it into a core channel for evading international sanctions and obtaining foreign currency. The proceeds have also been used to fund its nuclear weapons and missile programs.

CertiK’s latest report showed that North Korea-linked hacking groups stole about $2.06 billion in cryptocurrency in 2025, accounting for roughly 60% of global losses from crypto hacks that year. The report said North Korea has built systematic operations spanning attacks, asset transfers and money laundering, indicating that the activity has evolved from isolated crimes into a state-level revenue model.

North Korea has long deployed IT workers using stolen or false identities to apply for overseas remote jobs. U.S.-based accomplices receive company laptops on their behalf and install remote-access software, making the workers appear to be located in the United States. The scheme generates revenue for the sanctioned North Korean regime while giving its personnel access to corporate networks. Cryptocurrency companies are especially attractive targets because they hold readily transferable assets and operate critical infrastructure.

The U.S. Justice Department said on May 6, 2026, that Matthew Isaac Knoot and Erick Ntekereze Prince had each been sentenced to 18 months in prison. The two cases affected nearly 70 U.S. companies and generated more than $1.2 million for North Korea. Knoot was sentenced on May 1 and ordered to pay $15,100 in restitution and forfeit another $15,100. Prince was sentenced on May 6 and ordered to forfeit $89,000.

North Korea has long faced sweeping United Nations sanctions that restrict its legal exports and access to the financial system. It has consequently made cryptocurrency theft an important source of foreign currency to fund its nuclear weapons and ballistic missile programs. SVRN Chief Operating Officer Dave Schwed said Pyongyang targets exchanges, wallets and DeFi platforms rather than treating cryptocurrency merely as a payment tool.

CoinDesk reported on April 12, 2026, that North Korean hackers had recently spent six months infiltrating Drift, using false identities and long-term relationship-building to gain critical access. In the February 21, 2025, attack on Bybit, they moved $1.5 billion in about 30 minutes. The incident underscored both the difficulty of reversing on-chain transactions and the extremely short window for blocking stolen funds.

North Korea has long used overseas IT workers posing as job applicants to infiltrate crypto projects and gain salaries, system access and digital assets. The network uncovered by blockchain investigator ZachXBT involved about 140 people, indicating that the operation had developed into a sizable, sustainable source of foreign currency that could help North Korea evade international sanctions.

As of July 19, 2026, data released by ZachXBT showed that the team earned about $1 million a month from IT jobs and crypto scams. Members used simple passwords such as “123456” to manage payment and ranking platforms. Stolen crypto was converted into fiat currency and then transferred to Chinese bank accounts.

North Korean hackers have long used false identities to apply for remote IT jobs, gaining access to private keys, core code and internal systems after infiltrating blockchain and AI companies. Such attacks not only lead to cryptoasset theft but also increase the risks facing multinational companies in employee screening and supply-chain security.

A Chainalysis report found that North Korean hackers stole about $2.02 billion in cryptoassets in 2025, up 51% year on year and accounting for roughly 60% of the global total stolen. CertiK put the figure at $2.06 billion. In a recent case, an interviewer exposed a North Korean operative posing as a Japanese engineer by asking the applicant to criticize Kim Jong Un.

North Korea has long dispatched IT workers overseas to apply remotely for technology jobs using false identities, stolen data belonging to U.S. residents and “laptop farms,” then remit most of their salaries to Pyongyang. Such operations target blockchain and cryptocurrency companies and may also involve planting malware and stealing confidential information. The proceeds are alleged to fund North Korea’s nuclear weapons and ballistic missile programs.

On March 12, 2026, the U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) sanctioned six individuals and two entities, saying the network generated nearly $800 million for North Korea in 2024. A Vietnam-based operator converted about $2.5 million in cryptocurrency between mid-2023 and mid-2025. On April 15, the U.S. Justice Department separately announced that two accomplices had been sentenced to 92 and 108 months in prison for helping infiltrate more than 100 companies and generate over $5 million in revenue.
