Instead of monolithic ransomware, or a single piece of software that did everything and was highly automated, today’s ransomware tends to be modular and often obtained from a malicious developer or acquired “as a service”. There’s an organized dark ecosystem for ransomware with component and service supply chains, not dissimilar to the structures and practices we see in the legitimate world. It’s expeditious to change and morph, which makes traditional fingerprinting for signatures less effective.
