History And Development Of TeslaCrypt Ransomware The Virus

TeslaCrypt is an encryption program for files that targets all Windows versions including Windows Vista, Windows XP and Windows 7. The program was released in the first time around the February's end. Once it infects your computer, TeslaCrypt will search for data files and encrypt them using AES encryption such that you won't be capable of opening them.



As soon as all the data files on your computer are infected, an application will be displayed that provides information on how to retrieve your files. There is a link within the instructions that will connect you to the TOR Decryption Services website. This site will provide information about the current ransom amount, the number of files are encrypted, and how to pay the ransom so your files can be released. The ransom amount typically starts at $500. It is payable in Bitcoins. Each customer will have a unique Bitcoin address.



Once TeslaCrypt is installed on your computer, it generates an executable that is randomly labeled within the %AppData% folder. webarchive is launched and begins to look through your computer's drive letters for files that need to be encrypted. When it discovers a supported data file the file is encrypted and attaches a new extension to the file's name. The name is determined by the version that has affected your computer. The program is now using different extensions for files to encrypt encrypted files, with the release of new versions of TeslaCrypt. Currently, TeslaCrypt uses the following extensions: .ccc, .abc, .aaa, .zzz, .xyz, .exx, .ezz and .ecc. There is a possibility that you could make use of the TeslaDecoder tool to decrypt your encrypted files for free of charge. It depends on which version of TeslaCrypt is infected.



You should note that TeslaCrypt will scan all of the drive letters on your computer to locate files to encode. It can scan network shares, DropBox mappings and removable drives. It only targets network shares ' data files when the network share is marked as a drive letter on your computer. If you haven't mapped the network share as a drive letter, the ransomware won't be able to encode the files on the network share. After scanning your computer, the ransomware will delete all Shadow Volume Copies. This prevents you from restoring the affected files. The version of the ransomware is indicated by the application's title, which appears after encryption.



How does your computer get infected with TeslaCrypt



TeslaCrypt is a computer virus that can be infected when a user visits an unhacked website running an exploit kit and whose computer has outdated programs. To spread this malware hackers hack websites. They install a specific software program known as an exploit kit. This tool exploits weaknesses in the programs on your computer. Acrobat Reader and Java are only a few of the programs with weaknesses. After the exploit kit has successfully exploited the vulnerabilities on your computer, it automatically installs and launches TeslaCrypt.



It is important to ensure that Windows and all other programs are up to date. This will help you avoid potential weaknesses that could result in infection of your computer with TeslaCrypt.



This ransom ware was the first to target data files used by PC video games in a proactive manner. It targets game files from games such as Steam, World of Tanks and League of Legends. Diablo, Fallout 3, Skyrim, Dragon Age, Call of Duty, RPG Maker and many more. It has, however, not been established whether the game's targets result in more revenue for developers of this malware.



Versions of TeslaCrypt and the file extensions associated with it.



TeslaCrypt is constantly updated to incorporate new file extensions and encryption methods. The first version encrypts files which have the extension.ecc. The encrypted files, in this instance, are not paired with the data files. TeslaDecoder can also be used to retrieve the original encryption key. If the decryption keys were zeroed out, and the key was found to be partial in key.dat it is possible. It is also possible to find the Tesla request sent directly to the server, along with the keys for decryption.



Another version is available with encrypted file extensions.ecc or.ezz. If the decryption key was not zeroed out, one is unable to retrieve the original key. The encrypted files cannot be paired with the data files. The Tesla request can be transmitted to the server using the encryption key.



For the versions with an extension file name .ezz and .exx the original decryption key cannot be recovered without the author's private key in the event that the decryption key was zeroed out. Files encrypted with the extension .exx are linked to data files. The encryption key can also be got from the Tesla request to the server.



Versions with encrypted files with extensions.ccc.,.abc..aaa..zzz, and.xyz do not make use of data files. The decryption key cannot be stored on your computer. It is only decrypted if the victim captures the key while it was being transmitted to a server. You can retrieve the encryption key by contact Tesla. It is not possible to do this for versions prior to TeslaCrypt v2.1.0.



The release of TeslaCrypt 4.0



Recently, the developers released TeslaCrypt 4.0 sometime in March 2016. A brief analysis indicates that the latest version has fixed a flaw that previously corrupted files bigger than 4GB. It also comes with new ransom notes, and does not require encryption of files. It is difficult for users to learn about TeslaCryot or what happened to their files since there is no extension. With the new version, victims will need to follow the path outlined in the ransom notes. There are little established ways to decrypt files without extension without a decryption key or Tesla's private key. The files could be decrypted in the event that the victim captured the key as it was being sent to the server during encryption.
