The FBI is right--"Ransomware is on the Rise". Since the Helpdesk's first encounter with ransomware ("CryptoLocker") in November 2013, we've seen more and more variants of this sort of malicious software as criminals dodge and weave around the obstacles put in their way.
If you're not familiar with ransomware--particularly how to spot it and avoid becoming a victim--we highly recommend taking a look at the FBI's recent article in addition to the United States Computer Emergency Readiness Team's (US-CERT) alert, both linked below.
Please don't hesitate to get in touch with the Helpdesk if you have any questions.
