Malware that hijacks clipboard monitoring over 2.3 million bitcoin addresses

Bleeping Computer today revealed that they discovered a type of “clipboard hijacker” malware that monitors over 2.3 million bitcoin addresses.

A clipboard hijacker malware works by tricking users by switching the bitcoin address from their clipboard to another address that the attacker control. Since bitcoin addresses are long and hard to remember, this method works easily for hackers since users simply copy paste addresses from one application to another when sending cryptocoins.

The malware reportedly comes as a part of the All-Radio 4.27 Portable malware affecting Windows computers and monitors the Windows clipboard for a bitcoin address. Unless the user double-checks the address after pasting it, the bitcoin will go to the attackers’ address.

“While we have covered cryptocurrency clipboard hijackers in the past and they are not new, most of the previous samples monitored for 400-600 thousand cryptocurrency addresses,” their report on the malware read. They also posted a video showing how the malware works: 

Bitcoin users are advised to always double-check the address before making a transaction and to have a trusted antivirus program installed on their device.
