PeckShield: Hackers launder millions stolen from Horizon Harmony Protocol

Cybersecurity agency PeckShield said on Twitter that assets stolen last week from the Horizon Harmony Bridge have come into motion.

Security experts say that the hackers who stole $100 million in cryptocurrency sent three transactions from the address used in the hack, totaling about 30,000 ETH (about $36 million). The target was mixing service Tornado Cash, with $64 million worth of assets still in the hacker’s wallet.

Recall that on Thursday, during the hacking of the bridge of the first level of the Harmony’s Horizon blockchain, unknown people stole $ 100 million in Wrapped Ethereum (WETH), AAVE, SUSHI, DAI, Tether (USDT) and USD Coin (USDC), and then exchanged them for ethers. On Friday, experts began claiming that the cyberattack was made possible by an exploit of the Harmony protocol.

Harmony denied the experts’ opinion and in turn stated that it “found no evidence of any violations of our smart contract codes or vulnerabilities on the Horizon platform.” On Saturday, Harmony Protocol offered a $1 million reward for the return of the stolen money, warning that the company would otherwise go to law enforcement.

After the hack, Harmony assured its users that the theft did not affect its BTC bridge and that the company is working with national authorities and forensic experts to identify the culprit and return users’ money. In addition, Harmony has stepped up measures to protect projects from cyberattacks. Judging by the movement and laundering of assets, the hackers were not afraid of criminal prosecution by Harmony.
