Travelex was forced to take its websites offline after discovering the cyber-attack on New Year’s Eve. It later emerged that the ransomware gang responsible, Sodinokibi, had demanded £4.6m and was threatening to release customers’ personal data - including dates of birth and payment card information - into the public domain unless the company paid up. —The Guardian

Travelex are just the most recent high profile victims but Ransomeware is a growing trend and everyone is vulnerable.
All it takes is someone clicking a link in a spam email or activating macros in a malicious document without having proper security software in place.
In a few seconds, all your data will be encrypted and you'll have just a few days to pay a ransom in bitcoin to get it back. And there's no guarantee you will.
Ransomware creators and other cyber criminals involved in the malware economy are remorseless. They’ve automated their attacks to the point of targeting anyone and everyone.
