2.3M Bitcoin addresses targeted by malware

Avatar By Le Williams | 1 year ago

A new malware attack involving Bitcoin users’ Windows clipboard has been discovered actively monitoring 2.3 million targets, a Cointelegraph source reports.

The malware, known as “clipboard hijackers,” surreptitiously gains control of the user’s device memory, operating in the background to ensure users do not notice the malware’s presence.

The malware replaces copied Bitcoin address from the Windows Clipboard feature with the address of the attacker, in which the user later unknowingly pastes and transmits Bitcoins to the ‘hijacker’.

“Unless a user double-checks the pasted address, they will have no idea that this swap took place,” Bleeping Computer notes, adding an explanatory video about how the malware works.

Bitcoin users face a variety of vulnerabilities when using hardware to transact, regardless whether this is an Android smartphone, Windows PC or other devices.

The list of threats continues to grow, even incorporating emails, while other malicious entities swap out destination addresses in different ways.

Bleeping Computers adds, “Attackers recognize that users are copying and pasting the addresses and have created malware to take advantage of this.”

Experts suggest users should keeping up-to-date antivirus software running as a main defense against the problem, along with double-checking the destination Bitcoin address of a transaction if this has been entered using a copy-paste function.
