28 days ago, a hacker uploaded a new Smart Contract and started a fishing operation to collect as many signatures as possible from NFT owners via phishing fake listing / migration offers to the new OpenSea contract.

The Wyvern Exchange contract's transaction popup contained a private deal signing with the attacker's address for 0 eth.

And before the old OpenSea contract expired, the hacker executed his atrocity.

The hacker's wallet contains 641 eth ($1.7M)
