A compromised device belonging to a North Korean IT worker has exposed the strategies utilized by a group responsible for the $680,000 hack of the cryptocurrency fan-token marketplace, Favrr. According to blockchain investigator ZachXBT, the inquiry began when an anonymous source gained access to the worker’s computer. This access revealed various screenshots, exports from Google Drive, and Chrome profiles, providing insight into how the operatives devised and executed their schemes.

Through wallet activity analysis and matching digital signatures, ZachXBT confirmed that the source material linked them to the June 2025 exploit of Favrr. One wallet address, “0x78e1a,” was identified as having a direct connection to the stolen funds involved in this incident.

The compromised device indicated that the small team, consisting of six members, deployed at least 31 fake identities to secure blockchain development jobs. They gathered government-issued IDs and phone numbers and even procured LinkedIn and Upwork accounts to further conceal their identities.

An interview script retrieved from the device suggested they exaggerated their agricultural backgrounds, claiming experience with notable blockchain firms such as Polygon Labs, OpenSea, and Chainlink. Google tools played a pivotal role in their structured workflow. The group utilized drive spreadsheets to manage budgets and timelines, employing Google Translate to communicate effectively between Korean and English.

Further information extracted from the device revealed a spreadsheet detailing their expenses related to renting computers and covering VPN subscriptions for their operations. They also employed remote access software like AnyDesk, enabling them to control client systems without revealing their actual locations. VPN logs traced their activities across multiple regions, successfully concealing North Korean IP addresses.

Additional discoveries indicated the group's quest for methods to deploy tokens across various blockchains, exploration of AI companies in Europe, and the mapping of new targets within the crypto industry.

ZachXBT noted a recurrent pattern highlighted in several cybersecurity reports, illustrating North Korean IT workers securing legitimate remote jobs to infiltrate the cryptocurrency sector. By masquerading as freelance developers, they gain access to crucial code repositories, backend structures, and wallet systems.

Among the items found on the device were interview notes and preparatory materials, likely intended to remain on-screen or close by during conversations with prospective employers.
