Federal prosecutors said the crackdown targeted a network that used stolen identities of US citizens to get North Korean operatives hired by American companies as remote workers. The companies unknowingly shipped company computers to the operatives, who are alleged to have used them to access corporate networks and exfiltrate sensitive information.
The Justice Department said searches were conducted across dozens of suspected laptop farms in Texas, residences that CrowdStrike, which assisted the FBI in the investigation, described as "vital" to helping North Korean hackers overcome the physical, financial and legal challenges of operating outside the United States. At least 70 US-based companies were infiltrated, prosecutors said, in sectors including healthcare, cyber support, retail, communications and manufacturing across Ohio and 16 other states plus the District of Columbia. The affected companies were not named.
The hackers are believed to have generated around $3 million in funds through the scheme. In a separate public service announcement, the FBI warned that "thousands" of North Korean state-controlled IT workers are employed at Western companies, posing a significant national security and intellectual property theft insider threat.
"Increasingly, North Korean IT workers are turning to recruiting American facilitators to counter improved private sector detections and law enforcement actions," the Justice Department said. "These workers are hiring facilitators to complete a wider variety of tasks, and in some cases subcontracting entire jobs to third-party foreign nationals."
The announcement is the latest in a series of enforcement actions in recent years targeting the remote IT worker scheme, one of several revenue streams the North Korean regime pursues alongside hacks on cryptocurrency exchanges. Prosecutors said the operatives used realistic email addresses, spoofed LinkedIn profiles and extensive social media presences as cover.
