North Korean fraudulent IT workers are using stolen identities, AI-generated or altered personas, and domestic laptop farms to obtain remote IT and engineering roles, then access corporate systems from abroad through KVM or remote management tooling. Once inside, they can use valid credentials and trusted devices to steal intellectual property, exfiltrate customer or source-code data, move laterally with living-off-the-land tools such as PowerShell, WMI, and RDP, and potentially pivot to extortion or ransomware when exposed. Corelight argues that identity and endpoint controls often miss this activity because it resembles legitimate employee behavior, while network detection can expose abnormal protocols, lateral movement, DNS tunneling, cloud or storage exfiltration, and suspicious data flows.
