Bitcoin Address Poisoning Attacks: A Growing Threat to Cryptocurrency Holders
Experts warn of elegant social engineering scams targeting Bitcoin users, leading to notable financial losses.
Understanding Address Poisoning
A new wave of Bitcoin scams is targeting users thru a method known as address poisoning. This social engineering exploit manipulates transaction histories to deceive victims into sending funds to malicious addresses. Jameson Lopp, chief security officer at Casa, a Bitcoin custody company, first raised concerns about this emerging threat.
The core of the attack involves generating Bitcoin addresses that mimic the first and last characters of addresses found in a victim’s past transactions. This similarity can easily trick users who aren’t meticulously checking the full address before sending cryptocurrency.
Lopp’s Analysis of Blockchain Data
Lopp conducted an in-depth analysis of the Bitcoin blockchain to understand the prevalence and evolution of these attacks. His findings reveal a concerning trend:
the first such transactions did not appear until block 797570, July 7, 2023, which had 36 such transactions. Then, all was quiet until block 819455, December 12, 2023, after which we can find regular bursts of these transactions up until block 881172, January 28, 2025, then there was a 2-month break before they started up again.

Lopp further emphasized the scale of the problem,stating that over these 18 months,just shy of 48,000 transactions were sent that match this profile of potential address poisoning.

Additionally, he advocates for improvements in wallet interfaces to ensure complete address visibility, making it easier for users to identify potential scams.
