![]() #cybersecurity #respectdata Click to TweetĬrypto’s central appeal has traditionally been that it is unregulated, untethered from fiat currency systems and largely beyond the reach of world governments. The attackers were then able to generate BNB directly to wallets under their control. The Binance #crypto hack manipulated the Binance Smart Chain Token Hub bridge to pass forged proof messages. And the Qubit Finance bridge lost $80 million earlier in the year that involved yet another code vulnerability that allowed for the injection of malicious data. Nomad Bridge lost about $200 million in August when hackers came across a misconfiguration in its smart contract code allowing for “double dipping” on existing approved transactions. The breach of the Wormhole Bridge, in which attackers took about $320 million, also involved a flaw in code that allowed forgeries to be used to access the system. Other bridges have not fared so well, also losing substantial amounts of money. The Poly Network breach of August 2021 was roughly as big, but the hacker was convinced to return the funds under the auspices of a “bug bounty” demonstration. The biggest of these attacks was on Ronin Bridge, believed to be conducted by North Korea’s state-sponsored hackers and making use of social engineering (via an elaborate fake job offer) to gain access to an engineer’s account. The Binance crypto hack makes a bad year for decentralized finance worse, as multiple bridges have been hit for tens to hundreds of millions of dollars. Binance CEO Changpeng Zhao has assured platform users that their funds “are safe” and that more updates would be coming as the situation develops.Ĭhain of major crypto hacks prompting changes, increasing desire for regulations This prevents the thieves from moving them further, but recovery is very difficult without direct access to the wallet. The bulk of the stolen funds, totaling about $430 million, was trapped in the attacker’s wallets when Binance halted trading temporarily on Thursday. The attackers have thus far been able to exfiltrate about $110 million in coins to other blockchains. The attackers manipulated the BSC Token Hub bridge, which connected the BNB Smart Chain and BNB Beacon Chain to facilitate token exchange, to pass forged proof messages by exploiting a previously unknown vulnerability involving the use of previous known good legitimate proofs. ![]() ![]() Like some of the other crypto hacks this year that have ended up totaling hundreds of millions of dollars in damages, the Binance strike targeted a decentralized bridge. Crypto hack hits Binance for $566 Million, temporarily halts trading The crypto hack was reportedly sophisticated, making use of a forgery of the “proof of authority” system the Binance Smart Chain (or BNB Chain) uses for authentication of transactions. The attack led to a temporary shutdown of trading on October 6.
