Michael Barnhart is an investigator at DTEX Programs centered on North Korea.
They confirmed up on time, crushed deadlines, requested no questions.
It was a bit bizarre they by no means turned their digital camera on, however not a deal breaker.
Then they have been gone.
No discover. No forwarding particulars. Simply silence.
Throughout industries, a number of the highest-performing distant employees are vanishing and not using a hint. For a lot of firms, it’s not a burnout challenge—it’s a breach of belief. And in additional instances than you’d suppose, the foundation trigger traces again to the Democratic Folks’s Republic of Korea (DPRK).
On June 30, the FBI and Division of Justice introduced one of many largest crackdowns but on North Korea’s distant IT employee scheme, designed to covertly fund the regime. Almost 30 “laptop computer farms” throughout 16 U.S. states have been raided for his or her suspected position. The coordinated motion included three indictments, one arrest, the seizure of 29 monetary accounts, and the takedown of 21 web sites, a part of a sweeping effort to disrupt covert operations and cease sanctioned employees from infiltrating international firms beneath false identities.
The bust marks a uncommon and direct strike in opposition to one of many world’s most evasive cyber adversaries.
North Korea’s shadow IT workforce isn’t only a sanctions workaround. It’s a worldwide, for-profit operation embedding operatives inside main firms beneath false identities funneling cash, entry, and alternative again to the regime. And for those who suppose you’d spot it, you most likely received’t. These employees are quiet by design, expert by necessity, and skilled to use the blind spots in fashionable distant work.
The size of this infiltration is larger than many notice—and the indictments are unlikely to be the final. For now, each firm ought to be asking: May this be us?
Six crimson flags you employed a North Korean IT employee

In case you discover a hit, you may already be compromised. - Odd working hours for alleged U.S.-based employees
A distant dev claiming to be in Austin however pushing commits at 3 a.m. native time? That’s not hustle—that’s a time zone mismatch. DPRK operatives typically work from China or Russia and alter their hours to keep away from detection. Search for unusual bursts of late-week exercise or unnatural work cadences. - Use of distant entry instruments and anonymizers
IP-KVM switches. Mouse automation instruments. Anonymizing VPNs and distant desktop protocols. These aren’t simply IT oddities—they’re DPRK staples. In case you’re seeing distant entry patterns that don’t match declared person conduct, or tooling that simulates presence, examine. - Unusually low communication engagement
Digital camera at all times off. Silent in Slack. No questions, no friction. In lots of organizations, that’s seen as a plus. However low engagement, particularly from important roles, is a inform. DPRK operatives play invisible. That silence is usually the sign. DPRK operatives are skilled to remain invisible. In some instances, that quiet isn’t simply disengagement—it’s operational cowl. A number of pretend employees just lately vanished not as a result of they stop, however as a result of their units have been seized in worldwide stings. When somebody goes darkish, it might not be ghosting—regulation enforcement could be calling subsequent about your organization’s compromised programs. - Resume or referral patterns that really feel too familiar
Look nearer at your hiring pipeline. Reused resumes. Recycled phrasing. Overlapping profession timelines. These are indicators of templated personas.

When candidates begin to blur collectively, it’s time to dig deeper. - Discrepancy between interview and on-the-job efficiency
Crushed the interview. Fell flat on day one. It occurs, however when the particular person within the job doesn’t match the one that interviewed, that’s an issue. Voice changers, stand-ins, and deepfakes have all been used to slide by means of screenings. Even a fast follow-up can floor inconsistencies.
I employed a DPRK employee. Now what?
The first step: Don’t panic. Step two: Transfer quick.
When delicate buyer knowledge or mental property could have been uncovered, your response have to be fast, coordinated, and complete.
Right here’s what to do subsequent:
- Rapid containment and isolation
Droop all entry instantly—VPNs, cloud platforms, code repos, and e mail. Quarantine units and protect them for forensic evaluation; don’t wipe or reset something. Reset all associated credentials to stop additional entry. Quick motion right here issues. Each minute counts in stopping knowledge theft or sabotage. - Complete forensic investigation
Herald consultants skilled with insider threats and DPRK ways. Analyze logs from networks, cloud, endpoints, and code repositories to uncover uncommon entry or knowledge exfiltration. What did they contact? The place did the information circulate? Search for covert knowledge transfers or makes an attempt to cover exercise. - Assess the scope of publicity
Did they entry buyer knowledge, IP, supply code, or regulated content material? Consider compliance publicity beneath GDPR, HIPAA, or CCPA. Danger isn’t restricted to theft—suppose extortion, ransomware, or deeper compromise. - Coordinate cross-functional response
Herald authorized, PR, and HR. Authorized advises on disclosure; PR preps messaging; HR manages inner fallout. The sooner you coordinate, the extra management you keep. - Have interaction exterior authorities
Loop in regulation enforcement, together with the Web Crime Grievance Heart (IC3) and the Division of Protection Cyber Crime Heart (DC3). These aren’t simply company dangers; they’re geopolitical ones. Sharing intelligence strengthens your place and will assist stop future breaches.
Prevention past cyber and HR
Working identified IOCs is a begin—and a clear report is sweet information. However DPRK ops transfer quick. Prevention requires behavior-based visibility and tight cross-team alignment.
Pre-hire protecting measures:
- Conduct reside, on-camera interviews with IP/geolocation validation
- Independently confirm references and previous employment
- Use unscripted, technical Q&A to gauge actual experience
- Contain HR and authorized early in safety consciousness and hiring processes
Submit-hire protecting measures:
- Flag re-applications utilizing recycled knowledge or aliases
- Monitor for uncommon entry instances, distant software use, and VPN spikes

By fostering shut collaboration throughout inner and exterior safety, HR, threat, and authorized groups, organizations can construct a resilient insider threat program that detects and mitigates threats earlier than they escalate. Prevention is a crew effort, and conduct is the strongest sign.
North Korea—what’s subsequent
The newest and ongoing authorities actions have pushed the DPRK’s shadow workforce into the highlight. However publicity isn’t elimination. The playbook will evolve—new names, new instruments, new nations.
The fashionable insider received’t at all times look suspicious. They’ll look excellent. Till they disappear.
Understanding what to search for is the 1st step. Shutting it down for good is the mission forward.
