DPRK IT workers used fake IDs and purchased Upwork/LinkedIn accounts for developer jobs.

In recent years, North Korean IT workers have been leveraging fake identities and purchased accounts on platforms like Upwork and LinkedIn to secure developer jobs, raising concerns about cybersecurity and financial integrity. This practice, part of a broader strategy by North Korea to generate illicit revenue and engage in cyberespionage, has become increasingly sophisticated and widespread [1].

According to the US Treasury Department, thousands of highly skilled IT workers from North Korea are taking advantage of the demand for software developers to obtain freelance contracts from clients around the world, including in North America, Europe, and East Asia [1]. These workers often use stolen identities, posing as South Korean, Chinese, Japanese, or Eastern European citizens, and as US-based teleworkers. They operate through front companies in countries like China, Russia, Southeast Asia, and Africa, which act as intermediaries to secure jobs in Western companies [1].

The case of Christina Chapman, who was jailed in July 2025 for fraud, identity theft, and money laundering, highlights the extent of this problem. Chapman orchestrated a scheme that enabled North Korean IT workers to pose as US citizens and residents using stolen identities to obtain jobs at more than 300 US companies and two international firms [1]. This conspiracy generated over $17 million in illicit revenue over three years, demonstrating the financial impact of these scams.

The tactics employed by DPRK agents to evade detection have evolved, reducing reliance on traditional "laptop farms" and incorporating methods such as disabling secure access service edge tools and abusing privileged access from one organization to infiltrate another [1]. For example, the use of deepfake technologies and voice manipulation tools has been observed in job interviews, making it increasingly difficult to detect these fraudulent activities.

The threat is not limited to the United States; European businesses have also become targets. Google research indicates that North Korean IT worker scams are expanding into Europe, with suspected DPRK workers undertaking projects in areas such as web development, bot development, content management system (CMS) development, and blockchain technology [1]. This suggests a broad range of technical expertise among these workers.

To mitigate the risk, companies are urged to carry out tighter vetting of new hires and be vigilant about the authenticity of job applicants. Security awareness vendors and threat intelligence firms are also advising organizations to be cautious when hiring remote workers, especially those from high-risk countries. The evolving nature of these scams necessitates a proactive approach to cybersecurity and due diligence in hiring practices.
