$1.3M DPRK IT worker exploit, $1M recovered

A project unknowingly hired DPRK IT workers who exploited it for $1.3M; rapid tracing recovered $1M and exposed the hiring network behind it.

Amount involved: $1,300,000
Recovered: $1,000,000

A crypto project discovered the hard way that several of its 'remote developers' were DPRK IT workers operating under false identities. Once embedded, the operators exploited their access to drain roughly $1.3 million from the project's treasury.

Table 1: The hiring network as a table: fake names, the payment addresses each used, claimed locations, GitHub accounts, and emails. Shared addresses across rows are what tied supposedly independent contractors together.

Because the theft was detected and traced quickly, most of the funds never escaped: $1 million was recovered. The investigation went further than the single incident, documenting how the same cluster of fake developer identities had cycled through multiple projects: shared payment addresses, recycled résumés, and overlapping GitHub activity connecting supposedly independent contractors.

Figure 1: The exploit proceeds leave the project, pass through intermediaries and Tornado Cash, and surface at exchange deposit addresses, fast enough to recover most of it.

The thread became a widely-cited reference for teams screening remote hires, and part of the broader body of work mapping how DPRK IT workers infiltrate the industry.
