The biggest online threat to businesses and consumers today is ransomware, a category of malware that can encrypt your computer files until you pay a ransom to unlock them. With this practical book, you’ll learn how easily ransomware infects your system and what steps you can take to stop the attack before it sets foot in the network.

Security experts Allan Liska and Timothy Gallo explain how the success of these attacks has spawned not only several variants of ransomware, but also a litany of ever-changing ways they’re delivered to targets. You’ll learn pragmatic methods for responding quickly to a ransomware attack, as well as how to protect yourself from becoming infected in the first place.

Examine the organizations behind ransomware and the victims they target
Learn how wannabe hackers use Ransomware as a Service (RaaS) to launch campaigns
