BNB קייט-באזירט דעפי פּראָטאָקאָל אַנקר לייַדן הויפּט עקספּלאָיט - דעפי ביטקאָין נייַעס

Decentralized Web3 infrastructure provider Ankr has become the latest victim of a hacking attack targeting the defi space. The perpetrators who hit the platform were able to mint and steal a massive amount of tokens in a multimillion-dollar exploit.

Defi Protocol Ankr Hit by Unlimited Mint Bug Exploit Worth Millions

Ankr, a decentralized finance (defi) protocol based on Binance’s BNB Chain, has been exploited by a hacker who apparently used an unlimited minting bug. On-chain analysts broke the news on social media and the attack, which occurred on Dec. 1, was confirmed by Ankr.

On Friday, the Web3 infrastructure provider admitted on Twitter that its aBNB token had been exploited and announced it’s working with exchanges to suspend trading. In a follow-up tweet, it also insisted that all underlying assets on Ankr Staking are safe and infrastructure services unaffected.

אונדזער aBNB סימען איז עקספּלויטאַד, און מיר זענען דערווייַל ארבעטן מיט יקסטשיינדזשיז צו מיד אָפּשטעלן טריידינג.

Initial reports by blockchain security company Peckshield revealed the unknown attacker had been able to mint and dispose of approximately 10 trillion aBNB. It also found that some of the stolen funds had been transferred to the Tornado Cash mixer. A portion was bridged through Celer and Debridgegate to ethereum.

On-chain analysis firm Lookonchain said the exploiter minted 20 trillion tokens and dumped them on Pancakeswap, obtaining at least $5 million in the stablecoin USDC. The price of the Ankr reward-bearing staked BNB (aBNBc) has since collapsed from over $300 to a little over $1.50, at the time of writing.

Peckshield explained that a smart contract for the aBNBc token had an unlimited mint bug which the hacker took advantage of. Another report suggested the attacker had managed to gain access to the Ankr deployer key.

Binance Freezes $3 Million Worth Of Moved Funds

BNB קייט באשטעטיקט it was aware of the attack and has blacklisted the exploiter. Binance founder and CEO Changpeng Zhao tweeted that a developer private key was hacked and the hacker used it to update the smart contract. The exchange has frozen about $3 million of funds moved to its platform.

מעגלעך כאַקס אויף אַנקר און היי. ערשט אַנאַליסיס איז אַז די דעוועלאָפּער פּריוואַט שליסל איז כאַקט, און דער העקער דערהייַנטיקט די קלוג קאָנטראַקט צו אַ מער בייזע קאָנטראַקט. Binance פּאָזד ווידדראָאַלז עטלעכע שעה צוריק. אויך פראָזע וועגן $ 3m אַז כאַקערז מאַך צו אונדזער CEX.

דערווייַל, די BNB Chain-based destablecoin hay, that CZ referred to in his tweet, has lost its $1 peg, also as a result of an apparent exploit which was באשטעטיקט by the team of Helio Protocol. The token is currently trading at a little over $0.65.

The attacks come in a year of numerous security עקספּלויץ targeting defi and crypto platforms. According to blockchain forensics firm Chainalysis, the resulting losses in 2022 amount to $3 billion. In early October, BNB Chain was temporarily pauseed following a hack that cost close to $600 million.
