Svmuu News, "On-chain detective" ZachXBT disclosed on platform X that Russian over-the-counter (OTC) broker Aleksandr Khinkis is suspected of laundering over $4.7 million for ransomware groups through a single exchange account since July 2025, involving three ransom payments totaling 796 Bitcoin. The investigation reveals that the related funds were bridged from Bitcoin to Avalanche via a cross-chain path and transferred in 75 transactions to his exchange deposit address. Additionally, approximately $16.6 million is currently deposited in Aave but is being continuously withdrawn and cashed out in batches. ZachXBT pointed out that the suspect frequently operates in Southeast Asia and Australia, and his personal information has appeared multiple times in data breach incidents. Cross-jurisdictional activities may increase law enforcement difficulties, and he urged victims to report relevant addresses promptly to enhance freezing efficiency.
