Cryptolocker is one of the most notorious attacks we’ve seen in a while, one which definitely would ruin someone’s day, or in this case holiday spirit. As of December 16 6:53AM PST, Barracuda Real-Time Systems have intercepted and blocked a new version which has a 1 out of 54 detection rate according to VirusTotal.
Once downloaded and opened, Cryptolocker encrypts the data on the host computer, rendering all files to be unusable or opened until payment is made.
As always, any emails received should be treated with extreme caution. Users should always keep anti-virus up to date, and use best practices when opening suspicious emails from unknown senders.
