A joint investigation by BCA LTD, NorthScan, and ANY.RUN has provided an unusually clear look into one of North Korea’s most persistent infiltration methods. Instead of relying on malware or exploit chains, the operators tied to Lazarus Group’s Famous Chollima division attempted to slip remote IT workers into Western companies under stolen or borrowed identities. The research teams managed to watch this activity play out live, using purpose-built sandbox environments that the operators believed were ordinary developer laptops.
How the Scheme Works
The operation began with a familiar introduction: a recruiter message offering a remote IT position. In this case, the recruiter used the alias “Aaron,” also known as “Blaze,” a persona previously linked to Chollima activity. Blaze’s pitch followed the same pattern seen in earlier cases, presenting a job-placement “business” that would place a U.S. developer in a remote role, while a North Korean operator actually performed the work.
The goal remained the same as in past incidents. Operators attempted to borrow or take over an identity, pass interviews with AI-generated answers, work remotely by controlling the victim’s laptop, and route the salary back to DPRK channels. Once Blaze requested everything from SSN and government ID to full-time remote access and uninterrupted laptop availability, the researchers shifted into a controlled environment.
The Fake Laptops That Exposed the Operation
BCA LTD’s Mauro Eldritch deployed ANY.RUN’s long-running virtual machines, configured to appear indistinguishable from real personal workstations. They carried typical developer tools, normal browser history, and realistic usage patterns, along with network routing that matched U.S. residential activity.
These systems gave the research teams full visibility. They could watch sessions in real time, record every action, throttle the network, force crashes, and capture system snapshots. The operators, convinced they were working on legitimate devices, proceeded normally.
What Investigators Saw Inside Famous Chollima’s Toolkit
The sessions revealed a streamlined toolset focused almost entirely on identity takeover and remote access. Once the operators synced their Chrome profiles, they began loading the tools they rely on across many of these campaigns.
The setup included AI-driven platforms such as Simplify Copilot, AiApply, and Final Round AI, which helped automate job applications and provide pre-written interview responses. Browser-based one-time passcode utilities such as OTP.ee and Authenticator.cc appeared as soon as they collected personal documents, giving them the ability to manage the victim’s two-factor authentication.
Google Remote Desktop, configured through PowerShell with a fixed PIN, became the primary access channel. To validate the environment, the operators ran simple reconnaissance utilities such as dxdiag, systeminfo, and whoami. All traffic consistently moved through Astrill VPN, matching patterns tied to earlier Lazarus infrastructure.
At one point, an operator even left a Notepad message requesting uploads of a government ID, SSN, and banking details. The intent behind the scheme was unmistakable: complete control of the identity and workstation of a U.S.-based employee without pushing malware or triggering traditional defenses.
Why This Matters for Employers
The activity highlights a growing risk for hiring teams. Remote recruitment provides attackers with a quiet avenue into corporate environments. Instead of breaching external services or exploiting software vulnerabilities, they gain access by passing job interviews and taking control of an employee’s laptop once hired.
This raises the stakes beyond a single compromised worker. A successful infiltrator could reach internal dashboards, sensitive operational systems, or even managerial accounts if the organization does not have strong identity and endpoint controls. The investigation shows that these schemes rely on social engineering, identity theft, and remote-access tooling rather than traditional malware delivery.
Building internal awareness and giving staff a place to report suspicious interactions can play a significant role in catching these schemes early. Companies that review unusual requests, identity inconsistencies, or access demands are in a stronger position to prevent such infiltration attempts before they escalate into operational consequences.
