AI-Enhanced Social Engineering Targets HR Systems Through Fraudulent IT Worker Applications

North Korean threat actors are using generative AI to create convincing fake identities and job applications to infiltrate organizations as remote IT workers. The attackers exploit exposed OAuth-authenticated APIs in HR platforms like Workday to gather intelligence and submit fraudulent applications at scale. This sophisticated supply chain attack bypasses traditional technical defenses by targeting the human elements of recruitment and onboarding processes. Organizations must strengthen both their HR security controls and employee awareness programs to detect AI-generated deception during the hiring process.
