P2P coverage market provider Cover Protocol hacked but hacker returns stolen funds

Peer-to-peer coverage market provider Cover Protocol has been hacked, but in a twist on a traditional hacking story, the hacker has not only come forward but has also refunded the funds stolen.

Cover Protocol offers a service in which users can buy cover on anything related to cryptocurrency. Working on a P2P basis, users buy coverage that is staked against other users who essentially bet that the coverage will not need to be paid out.

The hack of Cover Protocol occurred today and involved the hacker exploiting a vulnerability in Cover Protocol’s liquidity mining and farming contract called BlackSmith. The hacker exploited the bug to mint at least $2 million in funds.

At this point, generally a company would panic, tick off a list of standard responses and write the lost funds off. But several hours after news of the hack was announced, a so-called “white hat” hacker called Grap.Finance claimed responsibility for the attack and said that he had returned all the stolen funds.

According to Coindesk, Grap.Finance returned about $4 million in funds stolen, including 1,400 Ethereum tokens, 1 million DAI tokens and 90 WBTC. The hacker is said to have minted 40 quintillion COVER tokens and sold more than $5 million of them this morning.

On Twitter, the hacker stated that it was up to Cover Protocol to take better care.

Despite the fact that funds have seemingly been returned  in a “white hat” hack, the damage to Cover Protocol’s reputation was real. Binance halted trading on COVER tokens while the price of the cryptocurrency also crashed, down 76% over the last 24-gours. COVER was trading at $878.48 as of 4:32 a.m. EST then dropped to a low of $48.95 as of 3:13 p.m. As of 9:35 p.m. is was trading at $210.75.

For Cover Protocol going forward, the company is floating the idea of issuing a new COVER token through a snapshot of existing balances before the hack took place. “The 4350 ETH that has been returned by the attacker will also be handled through a snapshot to the LP token holders. We are still investigating. Do NOT buy COVER,” the Cover Protocol team said on Twitter.
