According to Onchain Lens, wallets linked to the Drift Protocol exploit transferred 44,510 Ether (ETH) worth approximately $109 million to Tornado Cash over October 20-21. The transfers comprised 25,710 ETH on October 20 and 18,800 ETH on October 21, representing roughly 37% of the $295 million in losses from the April 1 attack on the Solana-based decentralized exchange.
Arkham-labeled attacker addresses reportedly retained approximately 56,569 ETH valued at $138 million following the deposits, leaving a substantial amount of stolen cryptocurrency outside the latest mixing activity.
