Recovering Ransomware-encrypted files from packet capture

This approach will likely be most useful for large enterprises that get attacked, since they're more likely to have a buffered packet capture of network traffic. This is still incredibly powerful given that most ransomware-prevention mechanisms are completely useless once the ransomware is already in your system.

I was pretty impressed that the blog post author thought of this. Pretty classic Eureka moment! I wonder if there's a way for regular people to do this with something like Packetbeat and tcpdump?
