Around $400,000 in ETH was stolen from around 9,000 wallets on the Abstract layer-2 network, which is built by the same company that makes the Pudgy Penguins NFTs. It appears that the affected wallets had all been used to play Cardex, a fantasy trading card game that had launched only a week prior.

Attackers compromised a private key belonging to the game's creators, which allowed them to drain wallets that still had an active session with the game.
