How artificial intelligence is taking on ransomware

Twice in the space of six weeks, the world has faced major attacks of ransomware -- malicious software that locks up photos and other files stored on your computer, then demands money to release them. It's clear that the world needs better defenses, and fortunately those are starting to emerge, if slowly and in patchwork fashion. When they arrive, we may have artificial intelligence to thank. Ransomware isn't necessarily trickier or more dangerous than other malware, but it can be much more aggravating, and at times devastating. Most infections don't get in your face about taking your digital stuff away from you the way ransomware does, nor do they shake you down for hundreds of dollars or more.
