A new update to the CryptXXX Ransomware has made significant design changes to both the ransom notes and the TOR payment site. Previously, CryptXXX, like many other ransomware infections, copied the layout and design of CryptoWall. With this recent update, they have now created their own template and changed the name of their decryptor to UltraDeCrypter. Could this indicate a formal name for the ransomware as UltraCrypter? If any significant changes are discovered in the ransomware, we will be sure to update this post.
