I kinda find it sadistically hilarious how they also target RPG Maker files as part of the encryption process...
oh well, hopefully everyone here is smart enough to avoid shady downloads, or at least use a good antivirus or heck...
read the comments before downloading.
EDIT:
Seems the TeslaCrypt encryption was based on the previous CryptoLocker ransomware (the desktop wallpaper looks almost the same)
and therefore has its own vulnerabilities, eventually CL got a "fix"
http://krebsonsecurity.com/2014/08/new-site-recovers-files-locked-by-cryptolocker-ransomware/apparently, a company in the Netherlands managed to find most if not all of the keys used to encrypt the files CL was using
and it let you recover them without ever having to pay ransomware owners a cent.
hopefully IF TeslaCrypt was loosely altered from CL, its more likely for them to keep some of those keys, but that's jus wishful thinking.
