How North Korean IT Workers Exploit Companies

North Korean IT workers have managed to secure employment in companies worldwide by impersonating legitimate remote workers. The FBI highlighted how these individuals copy company code repositories, such as GitHub, to personal accounts. Although copying code is not unusual for software developers, the scale of this activity poses a significant risk of intellectual property theft.

These workers also collect sensitive company credentials and session cookies to access networks from unauthorized devices. This creates opportunities for further compromises, such as installing malware or exfiltrating more data.

The FBI revealed that North Korean IT workers often log in from multiple IP addresses in short timeframes, raising red flags for unusual network activity. To mitigate risks, companies are urged to restrict user privileges, disable local administrator accounts, and monitor network traffic for suspicious behavior.

Strengthening Remote Hiring Practices

To address the issue, the FBI recommends that businesses improve their hiring and onboarding processes. Suggestions include verifying applicant identities, cross-checking resumes for duplicate information, and conducting in-person interviews whenever possible.

North Korean workers often use advanced techniques, such as AI-generated faces or face-swapping technology, to fake their identities during video interviews. Hiring managers should be cautious of these tactics and ask specific questions about applicants’ educational or geographical backgrounds.

The FBI also suggests partnering with third-party staffing firms that conduct thorough vetting and auditing of candidates. Reviewing payment platforms and monitoring changes in applicant contact information can also help detect suspicious activity.

The Growing Threat of North Korean IT Workers

North Korean IT workers, often referred to as “IT warriors,” have targeted hundreds of companies in the United States and abroad. They use U.S.-based laptop farms to mask their locations and gain access to enterprise networks.

In recent operations, law enforcement dismantled laptop farms in Nashville and Arizona that were linked to North Korean workers. These setups allow them to maintain the appearance of being U.S.-based employees, making it harder for companies to detect their true origins.

After being discovered and terminated, these workers use insider knowledge to extort their former employers. They threaten to leak sensitive information unless their demands are met, often causing significant financial and reputational damage.

Global Impact and Countermeasures

North Korea has generated significant revenue through illegal IT schemes, which support the country’s regime. The U.S. State Department has announced financial rewards for information that can disrupt these operations. Meanwhile, South Korea and Japan have also issued warnings about North Korean tactics targeting private companies.

In addition to IT-related schemes, North Korean state-sponsored hacking groups have been linked to cryptocurrency thefts totaling over $659 million in 2024 alone. These attacks highlight the country’s reliance on cybercrime to fund its activities.

In response, the Justice Department recently indicted two North Korean nationals and three facilitators involved in fraudulent remote IT work schemes. These schemes allowed North Korean workers to infiltrate at least 64 U.S. companies between 2018 and 2024.

Conclusion

The FBI’s warning underscores the growing threat posed by North Korean IT workers. By exploiting remote work vulnerabilities, these individuals have successfully infiltrated companies, stolen data, and demanded ransoms. Businesses must strengthen their hiring and cybersecurity practices to protect themselves from these sophisticated schemes. The collaboration between governments and organizations worldwide is essential to counter this threat effectively.
