Zhao said the hackers took around $100 million worth of crypto. BNB Chain later said in a blog post that a sum of 2 million of the cryptocurrency BNB – worth around $570 million – was removed by the hacker.
The Binance representative said in emailed remarks that the majority of the BNB stayed in the hacker’s digital wallet address, while about $100 million worth was “unrecovered”.
Blockchain bridges have progressively turned into the objective of burglaries, which have long tormented the crypto area.
BNB Chain upholds the BNB cryptocurrency, previously known as Binance Coin, which is the world’s fifth-biggest token with a market worth of some $46 billion, according to CoinGecko information.
Some $2 billion worth of cryptocurrency has been taken in 13 different bridge hacks, mostly this year, crypto examination firm Chainalysis said in August.

BNB Chain suspended its blockchain for a few hours before resuming at around 0630 GMT, it said in a tweet.
It said in its blog post that BNB Chain was “able to prevent the incident from spreading” by reaching the blockchain’s “validators,” – entities or people who verify blockchain transactions. BNB Chain said there are 44 validators across different time zones, without giving further subtleties.
BNB Chain said it would present a new “governance mechanism” to counter future hacks, as well as to extend the number of validators.
