Decentralized finance projects on the BNB Chain remain popular targets for hackers. During the Anrk protocol hack, attackers released 20 trillion aBNBc tokens.

The token name aBNBc stands forAnkr Reward Bearing Staked BNB - Users receive these tokens for staking BNB coins in the protocol. The hacker has already exchanged some of the funds received using the decentralized exchange Uniswap, the Tornado Cash mixer and various cross-chain bridges. He received about 5 million USDC.

So far there are few details about the hack.Apparently, the hacker either exploited a critical vulnerability in the Ankr smart contract or gained access to the private keys of the protocol administrators. Ankr developers said they are working with various platforms and exchanges to suspend trading with aBNB tokens.

Amid the hack, the rate of the aBNBc token fell to 99.5%. Another hacker took advantage of this. He exchanged 10 BNB for 183,384.92 aBNBc, then exchanged it for hBNB tokens and transferred it to the Helio protocol. Here he received a loan in BHAY0 stablecoins for $16 million and exchanged tokens for HAY0. As a result, he made a significant profit, and the rate of the HAY stablecoin fell to $0.2.

In early November, the Rubic bridge team lost $1.2 million in assets when a hacker gained access to administrator keys.
