Binance has announced a pause across the entire Binance Smart Chain (BSC or BNB Chain) following what appears to be one of the largest exploits in DeFi history.
An attacker has reportedly hacked another BNB chain user for 2 million BNB, worth $600 million.
Another DeFi Catastrophe
According to BNB Chain onTwitter, the ātemporaryā pause is due to āirregular activity,ā and a āpotential exploit.ā
āAll systems are now contained, and we are immediately investigating the potential vulnerability,ā said the team. It also claimed that āall funds are safe.ā
However, Twitter user and DeFi developer āfoobarā had something else to say about the situation. Heclaimedan attacker had stolen 2 million BNB from āsomebodyā on the chain ā worth roughly $600 million.
āThe attacker is spewing funds across liquidity pools and utilizing every bridge they can to get to safer chains,ā he added.
The user included a screenshot from a block explorer showing the suspect held $532 million in crypto, spread across various EVM-compatible chains and L2s. These include $421 million still on the BNB chain (79%) and another $53 million (10%) on Ethereum.
BNB chain data backs this up, showing exactly 1,020,094 BNB parked at the sameaddress, worth $288 million. The addressās cumulative holdings amount to $421 million, matching foobarās screenshot.
The explorer also includes a notice that the address has already been flagged as being part of the āBSC bridge hack,āreportedby the Web 3 cybersecurity group Ancilia. Furthermore, Tether ā the issuer of the worldās largest stablecoin ā has alreadyblacklistedthe account.
Can the Culprit Be Stopped?
BNB Chain has sinceconfirmedthat roughly $70 million to $80 million worth of assets were whisked off the chain before being paused. However, another $7 million of those escaped funds have already been frozen, thanks to āthe communityā and Binanceās āinternal and external security partners.ā
āWe are humbled by the speed and collaboration from the community to freeze funds,ā it added.
BNB Chain thanked over a dozen specific organizations for collaborating with its efforts, including CertiK, Ankr, and Coinbase Cloud.
Binanceās official Twitterannouncedthat all deposits and withdrawals for BNB at the exchange have been paused, due to āmaintenanceā on the BNB Chain.
Since blockchains are transparent ledgers, itās often possible for experts to identify, track down, and seize funds from thieves moving large funds. Last month, Chainalysis successfullyhelped authorities seize $30 million of stolen goods from the $600 million Axie Infinity hack.
