Euler (EUL) Finance exploiter sent 100 Ethereum (ETH) — worth $170,468 — to the Ronin Bridge exploiter on March 17.
On-chain analyst Lookonchain questioned whether the transaction showed that the two hackers were the same person or if the transfer was intentional.
The Ronin Bridge exploit was linked to the infamous North Korean hacker group Lazarus — circulating speculations of whether the group was also behind Euler Finance’s exploit.
Meanwhile, the transaction does not provide conclusive evidence about the relationship between both parties. The Euler Finance attacker had tried to obfuscate his transactions through sanctioned mixing protocol Tornado Cash. The attacker also sent 100 ETH to one of the victims of the exploit.
The Lazarus group was responsible for the $625 million Ronin bridge exploit in March 2022, according to the Federal Bureau of Investigation (FBI). The US Department of the Treasury added the hacker group to its Office of Foreign Assets Control (OFAC) sanctions list.
The FBI has also held Lazarus Group and APT38 as responsible for the $100 million exploit of the Horizon bridge. Although the North Korean government has denied sponsoring Lazarus and APT38, law enforcement agencies have linked several crypto attacks to North Korean hackers.
Euler Labs CEO said exploited codes were audited
The Euler Labs CEO Michael Bentley said the DeFi protocol has always been a security-minded project, adding that its smart contracts — including the vulnerable lines of code — were audited.
Bentley was responding to a victim who tweeted that the protocol had had ten different audits from six firms between 2021 and 2022.
In a March 17 Twitter thread, Bentley said this was the most challenging period of his life as he had to sacrifice time with his newborn son. For this, he said he would never forgive the attacker.
The CEO reiterated the project’s commitment to finding the attacker, urging anyone with information that could lead to his arrest to come forward.
Bentley concluded that:
“Everyone associated with Euler is working tirelessly to achieve the best possible outcomes as quickly as possible.”
