Another Bridge Hack: 10 Million Tokens Minted Without a Single Deposit
Published
An attacker minted 10 million unauthorised CYS on BNB Smart Chain through Cysic’s bridge on Saturday, and Cysic later blacklisted the receiving address and suspended the bridge. One report says the mainnet and user-wallet assets were not touched, while another says preliminary findings pointed to a breached database and a flaw in how the bridge processed mint messages.
What this rests on
What it means
Each sentence links inside to the piece that supports it.
Users and holders who track Cysic’s bridge activity would notice that the bridge was suspended and that one receiving address was blacklisted, with about 2.8 million CYS frozen there at 13:47:52 UTC. Anyone watching the chain would also see that the unauthorised minting happened on BNB Smart Chain on Saturday, while Cysic said its mainnet and wallet-held assets were not touched.
