Hackers have stolen at least $100 million in tokens from Binance, the world’s crypto exchange, in what appears to be another cross-chain bridge theft.
Binance said on Friday that coins worth between $100m to $110m had been taken in a hack that targeted BSC Token Hub, a bridge between two Binance systems.
The hack exploited a weakness that created extra BNB tokens on the network, Zhao said.
The incident caused the group to suspend the operation of the affected blockchain for about eight hours.
Binance founder Changpeng Zhao said: “The issue is contained now. Your funds are safe. We apologize for the inconvenience and will provide further updates accordingly.”
The news is a further blow to the sector, which has been hammered by a crisis that destroyed over half the value of bitcoin and other well-known coins over the past five months.
It comes at a time when digital assets are trying to recover from a credit crisis plus a surge in thefts. Cyber criminals have taken nearly $2 billion this year, up to the end of July, according to Chainalysis.
“Chainalysis estimates that $2 billion in cryptocurrency has been stolen across 13 separate cross-chain bridge hacks, the majority of which was stolen this year,” the group said in a report in early August.
“Attacks on bridges account for 69% of total funds stolen in 2022 so far,” it said, adding that “bridges are now a top target for North Korean-linked hackers, who – according to our estimates – have stolen approximately $1 billion worth of cryptocurrency so far this year, entirely from bridges and other DeFi protocols.”
