Cysic Exploit Wallet Moves $744,000 to Tornado Cash After Bounty Offer

A wallet linked to Cysic’s bridge exploit moved about $744,000 in Ether (ETH) and BNB to Tornado Cash on Friday, after Cysic Foundation offered a 10% recovery bounty.

The address transferred 300 ETH and 30.4 BNB to Tornado Cash. Tornado Cash pools funds from multiple addresses, which can make later tracing more difficult.

A vulnerability in Cysic’s bridge enabled the minting of 10 million Cysic (CYS) tokens on BNB Smart Chain on Saturday. Cysic suspended the bridge and blacklisted the receiving address, freezing about 2.8 million of the newly minted tokens.

On Thursday, Cysic Foundation offered the attacker a 10% bounty for returning 275.872 ETH, valued at about $665,000 and representing roughly 90% of the Ether proceeds identified in the incident. The foundation said its mainnet and assets already held in users’ wallets were unaffected.
