Forensic narrative

A user claimed on Twitter that he had mistakenly entered an NFT auction scam and was taken away by an art website worth 336,000 US dollars of Ethereum. However, the development of the story is somewhat unexpected, because the other party returned 100 ETH in full. In this scam, the victim reported that he inquired about the NFT auction on Monday from a certain population on Discord, and then he thought he was lucky enough to win the bid for the first NFT on the website and paid 100 ETH (about 336,000 US dollars) for this. ). However, according to a BBC report on Tuesday, a hacker exploited a security hole in the artist Banksy's website and set up a web page (banksy.co.uk/NFT) to sell so-called non-fungible tokens (NFT). In the end, although the hacker returned the money, the user still lost $5,000 in transaction fees. Attack method (per SlowMist): Phishing attack. Reported loss: $ 5,000.
