Ankr, a multi-chain Web3 infrastructure and Ethereum/BNB Chain-based decentralized finance (DeFi) protocol, has been compromised in an ongoing attack.
Ankr’s BNB Reward Bearing Certificate token (aBNBc) has token exploited by an unknown attacker.
The reasons for the exploit are still under investigation. However, it has been speculated that Ankr suffered a governance key compromise.
Our aBNB token has been exploited, and we are currently working with exchanges to immediately halt trading.

Trillions in Wrapped BNB
The attacker managed to mint over 50 Trillion $aBNBc (the equivalent of BNB on Ankr) and immediately dumped them on PancakeSwap, wiping out all liquidity from the DEX pool and making around $5 million in the process.
