Crypto exchange Bitfinex is offering up to $400 million to anyone who can lead it to the hackers who stole over 120,000 Bitcoin (BTC) in August 2016.

According to the company’s post on Aug. 4, it is even willing to reward the hackers themselves. The people behind the 2016 attack breached the security systems of Bitfinex and managed to complete around 2072 unauthorized transactions. The company clarified that this is its “latest effort” to recover these stolen funds.

Bitfinex explained how the reward will work:

“Those who put Bitfinex in contact with the hacker will receive 5% of the total property recovered (or equivalent funds or assets at current market values), and the hackers will receive 25% of the total property recovered (or equivalent funds or assets at current market values). Any payments made to those connecting Bitfinex with the hackers and the hackers themselves will be classified as costs of recovery of the stolen property.”
