A whale accidentally transferred and lost 1,155 BTC ($71 million) due to a tragic copy-paste error.
1. The hacker meticulously followed the whale’s blockchain activities and retrieved an address that is similar to the one generated by the whale.
2. The hacker then transferred 0 ETH to the whale’s wallet address, creating a transaction history that included the phishing address.
3. In the transaction history, the whale discovered an address with the identical numbers before and after their target address and accidentally copied and pasted the phishing address.
