CZ sounds alarm as ‘SEAL’ team uncovers 60 fake IT workers linked to North Korea
North Korean IT worker impersonators are targeting crypto firms through job applications and recruiter ruses, according to a new SEAL (Security Alliance) repository naming 60 suspected impostors. Binance co-founder Changpeng “CZ” Zhao amplified the warning on X, detailing malware-laced interviews and insider bribery attempts. This report examines what’s known, how companies are responding, and how to reduce exposure. The North Korean IT worker impersonators list and recent law-enforcement actions underscore rising operational risk across exchanges and startups
SEAL’s list of North Korean IT worker impersonators
SEAL (Security Alliance) published a public “team” page cataloging at least 60 identities allegedly used by DPRK operatives. Each entry includes alias, purported roles (e.g., “smart contract engineer”), and notes on companies allegedly “hiring” them intended as a screening aid for HR and security teams.
What SEAL’s data includes
The repository provides names/aliases, emails, claimed locations/citizenships, and links to developer profiles where available. SEAL previously outlined the broader DPRK “open to work” phenomenon and urged intelligence sharing across Web3 firms.
Tactics used in interviews and outreach
CZ’s X thread describes recurring attack patterns:
posing as job candidates to gain a “foot in the door” (dev/security/finance roles),
posing as employers, then sending a fake Zoom “update” during interviews, and
delivering malicious “sample code” or links to support channels; in some cases, bribery of staff or vendors for data access.
North Korean IT worker impersonators in action
Independent research has documented DPRK actors impersonating recruiters (e.g., Palo Alto Networks’ “Contagious Interview”), using fake LinkedIn outreach and multi-OS malware. These patterns mirror CZ’s warnings and SEAL’s findings.
Coinbase response and broader enforcement backdrop
Coinbase CEO Brian Armstrong said all hires must now complete in-person U.S. orientation; employees with sensitive access must be U.S. citizens and fingerprinted. The move follows new waves of DPRK job-fraud attempts. Business Insider
U.S. authorities have intensified actions against DPRK “remote IT worker” schemes. In June 2025, DOJ announced arrests, indictments, and seizures tied to North Koreans who used stolen identities to secure jobs at 100+ U.S. companies, including theft of source code and crypto. Treasury and CISA maintain advisories and red-flag guidance for employers.
DPRK crypto thefts and the Bybit case
Chainalysis estimates $1.34 billion stolen across 47 incidents in 2024 by DPRK-linked actors—more than double 2023 by value. In 2025, the FBI attributed the $1.5 billion Bybit theft to DPRK activity (“TraderTraitor”), the largest crypto heist to date.
Why crypto firms remain high-value targets
Public blockchains offer liquid, borderless value; Web3 startups rely on distributed teams and contractors, increasing the attack surface for North Korean IT worker impersonators and other social-engineering vectors. U.S. government guidance emphasizes identity verification, network access controls, and sanctions compliance.
Context & Analysis
Analysis: SEAL’s public list offers practical screening signals, but attribution remains complex; HR teams should treat entries as leads for enhanced due diligence, not definitive proof. Combining SEAL intel with government red-flags and zero-trust controls can meaningfully reduce exposure without over-blocking legitimate global talent.
Conclusion
Recruiter-style and interview-based cyberattacks are expected to rise, especially targeting organizations with remote or hybrid teams. Threat actors, including North Korean IT worker impersonators, are exploiting job interviews as opportunities to gain initial access and establish network footholds. These tactics take advantage of virtual hiring processes where verification gaps often exist.
Organizations that implement stronger defenses are in a better position to reduce this risk. By operationalizing candidate screening, using sandboxed technical assessments, and enforcing strict access governance, companies can detect malicious actors early and prevent interview processes from being exploited as entry points into their systems.
