As evidenced by the name itself, there was apparently not much security preventing a hoard of roaming strangers from breaking into the Nomad DeFi token bridge, allowing hundreds of unknown hackers and some users to walk away with more than $190 million in cryptocurrency, leaving behind Shame. Low in the project portfolio.
Late Monday, users began noticing tokens being mined from Nomad accounts.In multi-million dollar increments. Crypto security firm CertiK confirmed in a Tuesday analysis that the bridge protocol, which allows users to send tokens between separate block chains, was compromised thanks to a routine upgrade that allowed bad actors to bypass verification messages. Queen Telegraph It reported that the first transaction, likely the initial hacker, was able to remove about $2.3 million in crypto from the bridge.
Apparently, this hack allowed other users to exploit the bridge, essentially turning it into a free Black Friday for everyone. CertiK’s analysis also stated that the vulnerability was in the token bridge initialization process, which was introduced in the flawed upgrade, allowing users to copy and paste the hackers’ original transaction number and replace it with a personal number. In just four hours, the researchers said, other hackers, bots, and even members of the community drained the protocol in a “frenzied crowd.”
The crypto developer who goes to Foobar wrote on Twitter that this attack was “the first decentralized mass looting of a 9-digit bridge in history.” There are hundreds of addresses that show that they received tokens from the bridge during the exploit.
Some users have already reverted to the protocol, hanging their heads in disgrace and offering to return the stolen money. Some claimed it was an “accident,” while others said they were trying to protect their friends’ property, according to footage posted by Foobar. Devilama It shows that the current value of the blockchain is just under $16,000.
Others who said that they blew up the funds claimed to be “white hackers” trying to keep cryptocurrency safe and Waiting for money back, although Gizmodo has been unable to verify any of these white-hacking claims, nor how much money these well-meaning actors have attempted to save. A Bedouin representative told Cointelegraph that they are grateful to “several” white hackers who protected the funds.
For her part, Nomad wrote on Twitter It was “working around the clock to remedy the situation”. The developers said they contacted law enforcement as they worked to “identify the accounts involved and track and recover funds.” This apparent error in the software is not a good look when in the past the company venerated its belief in “Security first, the future through the chains. “
Of course, Nomad was the darling of crypto investors just a few months ago, Winning $22 million in the first round Led by crypto investor Polychain Capital.
This isn’t the only bridge that has been breached this year. It was the Ronin Bridge, which was used by the developers of the play-for-profit game Axie Infinity Hacked for nearly $625 million earlier this year. The hackers reportedly managed to exploit the network by contacting a developer on LinkedIn and, after several rounds of interviews, offered him a fake PDF job offer containing malware, allowing access to his computer. Despite efforts to re-encrypt the Bridge restorationthey still have to fully restore the previous users confidence in their systems.
