Nuclear Pack pushing CryptoFortress via CVE-2013-2551 - FR - 2015-03-04

I thought i was facing Teerac.A (aka TorrentLocker) which was showing that design :

Clicking on the "Buy Decryption software" :

The sample I got today is showing a close identity :  CryptoFortress

Clicking on the "Buy decryption software"

Samples :  Torrent Locker and a fresh CryptoFortress
