Bitcoin Address Poisoning Attacks Lead to Significant Losses

According to Odaily, Casa's Chief Security Officer Jameson Lopp has issued a warning about Bitcoin address poisoning attacks. These attacks involve the use of fake addresses that closely resemble a user's historical addresses, tricking them into sending funds to the wrong destination. Lopp's analysis indicates that such attacks have been active since July 2023, with nearly 48,000 related transactions recorded to date. Data from Cyvers reveals that by March 2025, these attacks have resulted in losses exceeding $1.2 million. Lopp advises users to carefully verify the complete address before sending funds and urges wallet interfaces to improve by avoiding the concealment of the middle part of addresses.
