What's the worst the ransomware world can throw at users?

Four years ago ransomware was a type of malware that had been kicking around for a decade to little effect.  By 2016, suddenly, it is everywhere, supplanting all other forms of malware as the number one menace.  Two things changed its status – the rise of Bitcoins (untraceable payment) and the example of FBI scareware which started to decline around 2012 but proved the principle that digital extortion can be profitable.

According to Symantec, 16 families were discovered in the decade to 2014, most spread on a very small scale such as Cryzip, the first small-scale ransomware to affect the UK. In 2015, by spectacular contrast, 27 families were recorded in that year alone. This year it is expected to hit up to 60.

Ransomware is difficult to stop even for Windows computers running antivirus although that is improving. The only defence is backup but even that can come under attack from ransomware if it is reachable from the infected PC. Longer term, ransomware will inevitably fade but extortion malware could move to the next tactic of threatening people with exposure for non-existent crimes such as downloading child abuse images. With more SMEs being affected than ever before, this threat has a way to run yet.
