Coinbase researchers announced that copycat attackers stole $88 million in last week’s Nomad hack.
Recently, one of the biggest hack attacks of this year was made on the Nomad Bridge. Nomad, a bridge that allows users to send and receive tokens between different blockchain networks, lost $190 million in this hack. Coinbase researchers, on the other hand, carried out a research by wondering about the origin of the attack on Nomad.
Coinbase: Most Nomad Attackers Were Copycats
According to researchers at crypto exchange Coinbase, more than 88 percent of the exploiters behind the Nomad hack were people who simply copied the main attacker’s code. Coinbase therefore describes those who stole around $88 million in tokens from the bridge as “impersonators”.
Stating that many of Nomad’s assets were stolen by copycats, researchers said:
“Many of the emulators used a variation of the original exploit, changing the targeted tokens, amounts, and recipient addresses. While the majority of tokens were claimed by only two of the actual attacker addresses, hundreds of people were able to claim some of the bridge’s assets.
According to Coinbase researchers, this also caused the original attackers to compete against hundreds of copycats.
Meanwhile, Nomad is currently working with security agencies and white hackers to recover some of the stolen funds, and even launched a bounty program last week. As of August 10, over $25 million in funds have been returned, but most are still missing.
