AirDAO announced the theft the following day, and stated that they were working to track and freeze stolen funds. They also offered the attacker a 10% "bounty" if they chose to return the stolen assets.
AirDAO exploited via social engineering attack
An attacker used social engineering techniques to gain access to the AirDAO project's liquidity pool. They then were able to drain 126.5 ETH (~$551,540) and 41.6 million AMB (notionally priced at around $500,000, but not very liquid). The thief then transferred the stolen tokens through various exchanges.
