Zusy Facebook Trojan – How Did I Get It
Facebook malware has seen as a rapidly growing threat by malware researchers. The virus has also been reported to cause massive infections on user systems via infected computers. Such infected computers may get an executable file slipped onto their computer via a malicious .ZIP file pretending to be an archive of an image or several images. In it, malware researchers report discovering a .jar partial file, and as soon as this file is opened, it activates a malicious script. This malicious script then connects to the cyber-criminals’ malicious server and downloads Zusy Facebook Trojan onto it.
