The Evolution and History of TeslaCrypt Ransomware Virus
TeslaCrypt is a file-encrypting ransomware program intended for all Windows versions including Windows Vista, Windows XP, Windows 7 and Windows 8. This ransomware program was first released towards the end February 2015. After it has infected your computer, TeslaCrypt will search for data files and then encrypt them with AES encryption so that you will no longer be capable of opening them.
As soon as all the data files on your computer have been affected, an application will be displayed that provides information on how to recover your files. There is a link in the instructions that connects you to the TOR Decryption Services website. This site will provide details about the current ransom amount and the number of files that have been encrypted, and the method you can use to pay to ensure that your files can be released. Ianblog.com The average ransom is $500. It is payable in Bitcoins. Each victim will have a unique Bitcoin address.
Once TeslaCrypt is installed on your computer, it creates an executable with a random label in the %AppData% folder. The executable is launched and starts to search your computer's drive letters for files to encrypt. When it detects a supported data file it encrypts it and adds an extension that is new to the name of the file. This name is determined by the version of the program that has affected your system. With the release of new variants of TeslaCrypt the program is using different file extensions for the encrypted files. At present, TeslaCrypt uses the following extensions: .ccc, .abc, .aaa, .zzz, .xyz, .exx, .ezz and .ecc. There is a possibility that you could utilize the TeslaDecoder tool to decrypt your encrypted files free of cost. It is, of course, dependent on the version of TeslaCrypt that is infecting your files.
It is important to note that TeslaCrypt will look through all drive letters on your computer to find files to encode. It can scan network shares, DropBox mappings and removable drives. It only targets network shares ' data files if the network share is mapped as a drive letters on your computer. If you don't map the network share as a drive letter, the ransomware won't secure the files on that network share. After scanning your computer, the ransomware will delete all Shadow Volume Copies. This is done to prevent you from restoring damaged files. The ransomware's version is indicated by the application's title, which appears after encryption.
How TeslaCrypt is able to infect your computer
TeslaCrypt is infected by computers when a user browses a hacked website that runs an exploit kit and whose computer has outdated programs. Hackers hack websites to distribute this malware. An exploit kit is a special software program that they install. This tool exploits vulnerabilities in the programs on your computer. Acrobat Reader and Java are only a few of the programs that are vulnerable. vulnerabilities. If the exploit tool is successful in exploiting the vulnerabilities on your computer, it automatically installs and starts TeslaCrypt without your knowledge.
You should, therefore, ensure that you Windows and other programs installed are up-to-date. It protects you from potential vulnerabilities that could lead to infection of your system with TeslaCrypt.
This ransomware was the first to target data files used by PC video games in a proactive manner. It targets game files from games like MineCraft, Steam, World of Tanks, League of Legends, Half-life 2. Diablo, Fallout 3 Skyrim, Dragon Age Dragon Age, Call of Duty and RPG Maker are just a few of the games it targets. It has, however, not been established whether the game's targets result in more revenues for the creators 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 include the extension.ecc. In this case the encrypted files aren't paired with data files. TeslaDecoder can also be used to retrieve the original encryption key. If the decryption keys were zeroed out, and a partial key was found in key.dat, it is possible. The key for decryption can be found in the Tesla request to the server.
There is a different version that comes with encrypted file extensions of .ecc and .ezz. One cannot recover the original encryption key without the ransomware's private key in the event that the encryption was eliminated. The encrypted files can't be coupled with the data files. The encryption key can be downloaded from the Tesla request sent to the server.
For the versions with an extension file names .ezz and .exx the original decryption key cannot be recovered without the authors' private key in the event that the decryption key was zeroed out. Files encrypted with the extension .exx are associated with data files. Decryption keys can also be obtained from the Tesla request to the server.
Versions that have encrypted files with extensions.ccc or.abc do not utilize data files. The key to decrypt cannot be stored on your computer. It is only decrypted if the victim captures the key while it is being transmitted to a server. Decryption keys can be obtained from Tesla request to the server. This is not possible for TeslaCrypt versions after v2.1.0.
Release of TeslaCrypt 4.0
Recently, the authors released TeslaCrypt 4.0 sometime in March 2016. A brief analysis indicates that the latest version has fixed a flaw that had previously caused corruption of files larger than 4GB. It also includes new ransom notes and doesn't utilize an extension to protect encrypted files. The absence of an extension makes it difficult for users to learn the details of TeslaCryot and what happened to their files. The ransom notes will be used to create routes for victims. It is not possible to decrypt files with no extension without a key purchased or Tesla's personal key. If the victim captures the key while it was being sent to an online server the files could be decrypted.
