Ransomware is like like a nasty game of tag: you can try to avoid it but once you’re hit, you’re out. For all we know about doing defence right, following the best practices advocated by NIST and SANS, this particularly malevolent threat has been on an upward trajectory out of the gate since 2016, after trending through 2015. It’s gone way beyond just phishing for targets and locking down individual files. Current strains are evasive: like tag, they figure out what anti-virus and security is running on the target system that might detect it and stay hidden. They now go after websites. They lock down entire servers. And they don’t care who the victims are – not even hospitals.
If you’ve been reading along with me on Twitter, or happen to be up at 2:00 a.m. like I am, you know that ransomware is what keeps me up at night. Along with some other brilliant minds in our security community who are dedicated to tracking and shutting down this ever-growing threat. These guys really know what they’re doing. Countless hours of research, investigation and analysis have produced this paper: Ransomware: Past, Present, and Future. There are definitive pieces that give the lay of the land and map out the course ahead. That is what this piece does. Sincere appreciation for the efforts of @ @ @ @ (and others) who put this together. They understand just how widespread the risk is, and time is not a luxury we have. This is essential reading for anyone in tech, security, business, critical infrastructure. Essentially, anyone who needs to safeguard the data and networks their daily business relies on.

Right now, here is what I would advise anyone. Back you stuff up, frequently, and separately from the network. Check your patch management situation. Where are your exposures? How are you handling security awareness, especially around phishing? Do you monitor your systems regularly, so that you have a baseline to compare events against?
And finally, take the time now and please read this: Ransomware: Past, Present and Future by Talos. Because the more people who know about ransomware and where it’s headed, the better we can all work together to secure things.
