Executive Snapshot

North Korea stole $2.02 billion in cryptocurrency in 2025, a 51% increase over last year, accounting for 59% of all global crypto theft. The Bybit hack alone netted $1.5 billion. But the method matters more than the number: DPRK operators are increasingly embedding themselves as employees inside crypto firms, using the hiring process as an attack vector. The enterprise security model treats insiders as trusted. North Korea treats the hiring pipeline as initial access.

Signal

Chainalysis reports DPRK-linked actors achieved 76% of all service-level compromises in 2025 through IT worker infiltration, impersonation of recruiters, and private key theft. Attackers use AI-generated video and voice changers in interviews. Once hired, they gain privileged access before executing large-scale theft. Binance reports detecting North Korean applicants daily.

Diagnostic Takeaway

Traditional insider threat programs assume employees have been vetted. DPRK inverts this assumption by weaponizing the vetting process itself. The attacker is not bypassing background checks. The attacker is passing them. Identity verification that relies on documents, video calls, and reference checks is insufficient against adversaries who treat job applications as persistence mechanisms.

Executive Verdict

Hiring is a privileged access ceremony. Any organization that cannot cryptographically bind a human identity to ongoing access has accepted nation-state insider risk by design. The replacement principle: identity must be continuous, not episodic. A background check at hire is not identity assurance at access. DPRK's 45-day laundering window is longer than most organizations' insider threat detection cycle. By the time anomalous behavior triggers review, the funds are already in Chinese-language mixing services and the employee has resigned.

Framework: Identity Failure Layer

• Element 1 (Identity Provenance Collapse): Background checks verify credentials, not biological identity. Adversaries pass verification because verification was never designed to detect them.

• Element 5 (Trust Delegation Without Presence): Hiring grants ongoing access based on a single episodic verification event. The human who passed the interview is assumed to be the human at the keyboard months later.

• Element 9 (Authorization Without Continuous Binding): Privileged access persists after the identity ceremony ends. The attacker inherits the trust of the role, not the scrutiny of the access.

Action

Audit your remote hiring pipeline for roles with privileged access to financial systems or cryptographic keys. Evaluate whether your identity verification can distinguish between a qualified candidate and a state-sponsored infiltrator using AI-generated deepfakes. If your answer is "we rely on video interviews and background checks," you have already accepted this risk.

Decision and corrective implications are addressed in this week's CISO Briefing.
