> The wallet sold 7.2 million CYS before the blacklist took effect. About 306.6 ETH worth roughly $727,000 reached Ethereum.

Ten million Cysic tokens (CYS) were minted through Cysic’s bridge on BNB Smart Chain, and the recipient wallet sold 7.2 million before being blacklisted 76 minutes later.

The mint was recorded at 8:31:38 a.m. ET (12:31:38 UTC) on Oct. 17. The blacklist took effect at 9:47:52 a.m. ET (13:47:52 UTC), 76 minutes and 14 seconds afterward. About 2.8 million CYS remained in the wallet.

The wallet exchanged 5.65 million CYS for 588,315 USDT between 8:36 and 8:41 a.m. ET, then traded another 1.55 million for about 220 BNB between 8:57 and 8:59 a.m. ET. Roughly 306.6 Ether (ETH) reached Ethereum, valued at about $727,000 using an Oct. 18 price near $2,372.

The Cysic Foundation said unauthorized access to a database supporting bridge services and a flaw in message processing enabled the mint. It said the incident did not affect its mainnet or assets already held in user wallets. The bridge remains suspended during a security review, and transfers, swaps and the final loss figure remain under review.
