According to court documents, North Korea used stolen or borrowed identities to infiltrate the networks of U.S. companies and collect funds to donate to North Korea's weapons program in violation of U.S. and United Nations sanctions. It has sent thousands of skilled IT workers around the world. The scheme involved more than 300 U.S. companies, including many well-known Fortune 500 companies, using accounts on U.S. payment platforms and online job sites, proxy computers located in the U.S., and U.S. individuals and entities, some of which were fraudulent.

Prosecutors allege the scheme began in early 2020 when a group of overseas IT workers began performing services remotely for U.S. companies. To get the jobs, the workers stole the identities of Americans and applied for remote jobs in the United States. Once they obtained jobs in the United States, they were able to gain access to the internal systems of American companies, sometimes through employment agencies. Not only did they steal data and money, they were paid millions of dollars for their work and falsely reported that information to the IRS.

The indictment describes them as “one of the most prominent media and entertainment companies in the world,” all of which were Fortune 500 companies. Prosecutors allege that the overseas IT employees also leaked (a fancy technical term for stealing) data from at least two U.S. companies, including a multinational restaurant chain and an American clothing brand. .
(Overseas IT workers also attempted to gain employment and access to information at two different U.S. government agencies on three other occasions, but these efforts were generally unsuccessful.)
The FBI also executed a search warrant on a US-based “laptop farm.”Laptop farms are residences that host the laptops of IT workers overseas, so the IT workers appear to be operating in the United States
Chapman's residence was among those searched in October 2023 based on a warrant issued in the District of Arizona. She is accused of setting up a laptop farm at her home to support the scheme. Prosecutors also allege that she took and forged her own payroll checks and deposited overseas IT workers' salaries from U.S. companies directly into U.S. financial accounts.
“Using stolen identities of U.S. citizens is a crime in itself, but using that identity to procure jobs for foreigners with ties to North Korea at hundreds of U.S. companies is a national crime. “This would jeopardize the national security of the country.” Guy Ficco, Director of IRS-CI; “For more than 100 years, IRS Criminal Investigation special agents have been tracking that money, and their financial expertise has once again thwarted criminals in their tracks.”

Chapman is currently being represented by a federal public defender, according to court documents.
John Doze remains at large. The U.S. Department of State has announced a reward of up to $5 million for information related to Chapman's co-conspirators. The Department of Justice encourages anyone with information regarding Jiho Han, Haoran Xu, Chunji Jin, Zhonghua, related individuals or entities, or their revenue generating or money laundering activities to contact the Justice Bounty Office through the Tor-based tip reporting channel: he5dybnt7sr6cm32xt77pazmtm65flqy6irivtflruqfc5ep7eiodiad.onion (requires Tor Browser).
“The charges in this case should serve as a wake-up call to American companies and government agencies that employ remote IT workers,” said Assistant Attorney General Nicole M. Argentieri, head of the Justice Department's Criminal Division. These crimes benefited the North Korean government, provided a source of income, and in some cases had confidential information stolen by co-conspirators. The Criminal Division remains steadfast in its commitment to prosecuting complex criminal schemes such as this one. ”
Oleksandr Didenko

Didenko, in conjunction with his co-conspirators, facilitated the operation of his US-based farm of at least three laptops and at one time hosted approximately 79 computers.
Prosecutors allege Didenko admitted in the messages that he believed he was supporting North Korean IT workers. Additionally, in November 2023, a US cybersecurity firm discovered documents on an online storage platform related to North Korean IT workers' attempts to obtain employment as remote workers. According to court documents, the company assessed with “high confidence” that the documents may have come from a spy group with ties to North Korea. “Some of the documents we discovered contained information that pointed more definitively to North Korea,” the company said. Many of the passwords associated with these documents were created in Korean, typed on U.S. keyboards, and some passwords include words used only in North Korea. Additionally, Korean keyboard language settings were discovered on the computers used by the attackers behind these campaigns. ”
The document included guides and tips on securing employment, how to write a cover letter, creating a resume, sample resumes for alleged IT employees, interview scripts, and more. Several of the documents relate to online job listings seeking employees secured by North Korean IT workers, including a U.S. job posting that was later tied to a computer found at Chapman's residence through business records. (Prosecutors say Didenko and Chapman's activities are related).
One of Didenko's overseas IT worker customers also requested that a laptop be sent from one of Didenko's U.S. laptop farms to Chapman's laptop farm, and that one of Didenko's overseas IT worker customers was also asked to send a laptop from one of Didenko's U.S. laptop farms to Chapman's laptop farm. shows that these cells are interconnected. Search warrants were executed in the Southern District of California, the Eastern District of Tennessee, and the Eastern District of Virginia on four U.S. residences associated with laptop farms managed by Didenko.
