The attackers were able to siphon 769 million $WSM from the contract, which was notionally worth around $7 million. However, the token lacks liquidity to support swapping hundreds of millions of tokens without depressing the price, and the token price dropped around 35% in the wake of the attack as the thief began to cash out over several days.
Meanwhile, WSM announced that they would be issuing a new token to replace the stolen tokens, and "renew[ing] the liquidity pool"... somehow.
