The Olympus DAO cryptocurrency project has become another victim of a hacker attack – the attacker withdrew 30,000 OHM tokens, but returned the stolen funds a few hours later.
So far, the motive for the return is not clear – perhaps the project has encountered a “white hacker”, or the attacker has changed his mind about the funds received. The hack happened on Friday morning, after which the developers stated:
“The hacker was able to withdraw approximately 30,000 OHM (about $300,000) from the OHM contract in the Bond protocol. The vulnerability was not discovered during three audits or during our internal code reviews. There have also been no reported vulnerabilities on the Immunefi platform. We have closed all markets affected by the vulnerability and all other funds are safe.”
However, a few hours later, the Olympus team reported that all the stolen funds were returned and work was underway with the Bond Protocol to resume operation.
As PeckShield specialists emphasized, the vulnerability was found in the contracts of the Bond Protocol itself, so the Olympus DAO team is not responsible for the hack. A hacker exploited a vulnerability in the BondFixedExpiryTeller smart contract.
Note that if a hacker reported a vulnerability on the Immunefi platform, he could claim a reward of up to $3.3 million.
A few days ago, the Moola Market DeFi protocol was hacked. Hackers managed to withdraw assets worth $9 million.
