Summary
- An attacker drained $8.07 million from Coinsbuy across TRON and Ethereum in under an hour on Aug. 9, with blockchain researchers linking both chains into a single operation via cross-chain swapper Bridgers.
- Roughly 79% of stolen funds moved through instant exchange FixedFloat across 50 single-use addresses. ChangeNOW froze a six-figure sum, and approximately $542,000 in ETH has not moved.
- Coinsbuy refilled the drained wallets within 24 hours, suggesting private keys were not compromised, but the exchange has not explained how the withdrawal path was accessed.
