BitMEX Research discovered a carefully designed scam targeting Bitcoin users. Someone is using Bitcoin addresses from the 2010s to send transactions with OP_Return outputs, including the 1Feex... address that had approximately 80,000 BTC stolen from Mt.Gox. The OP_Return information in these transactions refers to a certain website, which claims: "This digital wallet appears to be lost or abandoned. Our clients have presumed ownership and are seeking confirmation if there is a real owner." The page then provides a form requesting personal details. [CoinWorld]
