Over one six-month period last year, Dell researchers tracked another variant, CryptoWall, that infected some 625,000 machines and netted $1,101,900.Ĭrypto-ransomware is both effective, and surprisingly easy for hackers to control - it doesn't take complex skills or super-specialized knowledge to deploy. In the first six months after it emerged in September 2013, Cryptolocker ransomware infected more than 200,000 computers security researchers estimate. Those Maine cops weren't alone: Police departments from Massachusetts to Illinois have admitted in recent months to having been infected by crypto-ransomware and hundreds of thousands, if not millions, of private citizens have dealt with the same. In the past couple of years, it has it become widespread.
Ransomware is a decades-old technology that has enjoyed a resurgence among hackers because of its ease of use, its profitability, its recent confluence with cryptography, and its devious effectiveness.
