A variant of Curve-Tor-Bitcoin (CTB) Locker ransomware  is being distributed in a spam campaign now offers victims additional time to pay the ransom, but also requires them to pay a whole lot more than previously, according to the latest research by Trend Micro. This is just the latest wave of this type of malware and users need to be vigilant.

The bad news is that, as its name implies, ransomware holds your system ransom. The first thing this package does is corrupt your files – all your files. Photos, videos, office documents; Local files, network files, shared files… Then a warning screen from the criminals alerts you, telling you that your files are “encrypted” and demanding that you pay a ransom via electronic fund transfer or your files will be lost forever.
