Security researchers have discovered a keylogging Trojan that captures mouse clicks as well as key strokes. PWSteal-Bancos-Q targets customers of online banking and financial institutions primarily in Brazil. However Australian anti-virus firm PC Tools warns that variants could be created to affect additional online financial sites worldwide.
As well as capturing user keystrokes, PWSteal-Bancos-Q also takes snapshots of the users' mouse clicks and then sends the captured information via file transfer protocol (FTP) to the Trojan's author. The technique is designed to overcome the use of virtual keyboards by many online banking sites in an effort to avoid keylogger infections.
