Ransomware: A Growing Menace could be extracting fraudulent payments from as many as 3 percent of victims, a Symantec report has calculated. The company identified at least 16 distinct families circulating among mostly Russian-based criminal groups, each with its own development cycle. In a single month 2.9 of 68,000 people infected by the malware it controlled were paying up to $33,600 (APS21,000) in just one day. Some groups must be earning millions from ransom scams which explains the alarming growth of the problem.”]
