He subsequently mapped many smaller month-to-month deposits from unrelated initiatives into the identical alternate pockets.
Two GitHub accounts, “devmad119” and “sujitb2114,” record wallets that intersect the stolen fund path.
Each accounts share indicators that ZachXBT related to North Korean IT employees, together with Korean language system settings, Astral VPN classes, and Asia-Russia time zones, regardless of résumés that declare US residency.
Favrr exploit follows the identical payroll path
A second incident surfaced on June 25, when the freelance providers token undertaking Favrr misplaced greater than $680,000 following its itemizing on a DEX. On-chain evaluation linked the exploit to the consolidation pockets 0x477, which obtained recurring funds from Favrr payroll addresses 0x1708 and 0x6412.
Gate.io deposit tackle 0xab7 obtained a part of the stolen Favrr tokens, and was beforehand funded by the suspected developer behind “sujitb2114”.
Favrr introduced that it will refund all preliminary decentralized providing contributors, cancel its MEXC itemizing, and provoke a radical audit of its codebase. The undertaking added that it’ll publish a brand new launch timeline “within the coming weeks” and suggested customers to keep away from buying and selling impostor tokens within the interim.

The investigator plans to launch combination knowledge on payroll flows to wallets tied to the identical North Korean cluster, contending that fundamental due diligence checks would have flagged the hires.
The stolen funds from the ChainSaw collections stay idle, whereas most Favrr proceeds have already handed via Gate.io and a number of other nested providers.
