Ransomware is one of the nastier and more insidious threats to emerge in the last decade, and the attackers using it have targeted consumers and businesses alike. Threats such as CryptoLocker, Locky, Cryptowall, and many others have been locking up users’ files and demanding hundreds or thousands of dollars in order to decrypt them. Security researchers and law enforcement have had some success in going after ransomware gangs, but they are highly distributed and amorphous and difficult to get a handle on. To find out where this mess came from, who’s behind it, and wha we can do about it, Dennis Fisher talked with Juan Andres Guerrero-Saade of Kaspersky Lab, Jessy Irwin, and Patrick Wardle of Synack for this special edition of the podcast.
