Bitrovo froze $3 million due to Ankr hack

Bitrovo’s CEO announced that the exchange has frozen nearly $3 million in assets acquired by hackers as a result of the Ankr exploit.

The DeFi Ankr protocol underwent a massive hack, during which the attacker was able to issue 20 trillion aBNBc tokens. The hacker then exchanged some of the funds for 5 million USDC using the decentralized exchange Uniswap, the Tornado Cash mixer, and various interconnect bridges.

Beosin, a company that investigates blockchain security, tweeted that the attack was likely caused by a private key compromise because the developer changed the address of the implementation contract before the attack. The attacker then called the mintApprovedTo function, which allowed anyone to mint tokens in unlimited quantities.

Bitrovo CEO Changpeng Zhao said the exchange was able to block about $3 million in hackers from hacking Ankr.

Responding on Twitter to comments from users that hackers could have seized assets worth five times the blocked amount, the head of Bitrovo said he was ready to bring in an independent auditor to verify it.

Earlier the cryptocurrency exchange Bitrovo announced the conclusion of a cooperation agreement with Mazars, which will be the auditor of the new Proof-of-Reserve (PoR) system.
