What is Bitshifter ransomware? And how does this malware function?
Bitshifter ransomware is a newly developed file-encrypting threat which appears to be under development and created by independent group of con artists. Unlike other similar threats, Bitshifter is quite different since it attacks the virtual community with only a plain HTTP text command instead of its independent GUI.
