As Ransomware gets more automated, the ability to make money by hitting many small targets increases. People must begin thinking about their own personal files as potential targets of unwanted encryption.
Less than a week ago, Webroot Threat Blog discovered CoinVault, a new breed of ransomware. “This is the first encrypting ransomware that I’ve seen which actually gives you a free decrypt,” Moffitt wrote.
Victims infected with CoinVault are asked to pay 0.5 bitcoins, which is currently equal to about $188, for the decryption key. Every 24 hours that pass without the victim paying, the cost increases. Victims can select any one file to be decrypted for free. (Source)
