Lots and lots of little ransomware and in-dev variants released this week. Of particular note is the quick release of two Locky variants that used .sh*t and then a day later the .thor extension for encrypted files.
New variants of Locky are being released at a rapid rate lately. Yesterday, we had a new variant that appends the .SH*T extension to encrypted files and a new one was released that now uses the .THOR extension. This version is currently being distributed via SPAM and further details can be found in the article.
