You should be aware that TeslaCrypt will look through all drive letters on your computer to find files to encode. It can be used to encrypt network shares, DropBox mappings, and removable drives. However, it only targets the files on network shares if you have the network share assigned as a drive letter on your computer. If you haven't yet mapped the network share as a drive-letter, the ransomware will not secure the files on that network share. Once it is done scanning your PC, it will erase all Shadow Volume Copies. The ransomware does this to prevent you from restoring the affected files. The version of the ransomware is identified by the title of the application that appears after encryption.
How TeslaCrypt infects your computer
TeslaCrypt can infect computers when the user visits a hacked site that has an exploit kit and outdated programs. Hackers hack websites to distribute this malware. They install a special software program known as an exploit kit. This tool exploits weaknesses within the programs on your computer.

It has, however, not been ascertained whether games targets will result in increased revenue for developers of this malware.
Versions of TeslaCrypt, and the associated file extensions
TeslaCrypt is constantly updated to incorporate new encryption methods and file extensions. The first version encrypts files that have the extension .ecc. In this case the encrypted files aren't paired with data files. The TeslaDecoder can also be used to recover the original encryption key. It is possible if the key used to decrypt was zeroed out and partial key was found in key.dat. The decryption key could be found in the Tesla request that was sent to the server.
Another version is available with encrypted file extensions.ecc or.ezz. The original decryption key without having the private key of the authors of the ransomware if the decryption was zeroed out. The encrypted files can't be paired with the data files. The Tesla request can be sent to the server with the encryption key. minecraft
For the version that has an extension file name .ezz and .exx the original decryption key is not obtained without the authors' private key in the event that the decryption key was zeroed out. Files encrypted with the extension.exx are able to be linked with data files. The encryption key can also be got from the Tesla request to the server.
Versions that use encrypted files with extensions.ccc.,.abc..aaa..zzz, and.xyz do not utilize data files. The key to decrypt cannot be stored on your system. It is only decrypted if the victim captures the key as it is being sent to a server. You can retrieve the encryption key by contacting Tesla. It is not possible to do this for versions prior to TeslaCrypt v2.1.0.
TeslaCrypt 4.0 is now available
The authors released TeslaCrypt4.0 sometime in March 2016. The latest version addresses an issue that caused affected files larger than 4GB that were corrupted. It also has new ransom notes and doesn't utilize an extension to protect encrypted files. The absence of an extension makes it hard for users to find out about TeslaCryot and what has happened to their files. The ransom notes will be used to create pathways for victims. It is impossible to decrypt files with no extension without a purchased key or Tesla's personal key. The files can be decrypted if the victim captured the key as it was transmitted to the server during encryption.
