Virus software that blackmails users by encrypting their hard drives or locking them out of the computer. It then demands payment to restore it. A favorite ploy is an FBI message claiming the user has child pornography on the computer, and a fine must be paid or else risk arrest. After paying the blackmail on any of these ransomware attacks, very often via Bitcoin, the user's machine may or may not be restored. Also known as a "cryptovirus" or "cryptotrojan."In 2013, the creators of CryptoLocker collected millions in ransom by infecting Windows PCs until its distribution was halted a year later by the FBI and Interpol. CryptoLocker was the inspiration for other ransomware variants (gotta love that entrepreneurial spirit!). See Petya.Mobile Phones TooIn 2014, using the same FBI scare tactic, thousands of Android users found their phones locked with demands for payment. See scareware and wares.Even CitiesIn 2019, two Florida cities paid their attackers more than $1 million to remove ransomware. Cybercrooks are increasingly asking for hundreds of thousands of dollars when they have breached a large organization or government entity. If there is any bright side to this, more organizations both public and private, are developing or improving their backup and recovery programs. See disaster recovery and cybercrime.Ransomware ProtectionAs a result of this delightful phenomenon, numerous firms such as Trend Micro, Symantic, Malwarebytes and Avast Software have added ransomware protection in their lines of security products.
