TrueCrypter Ransomware – Distribution Ways

TrueCrypter ransomware is distributed in several ways. One of the most effective ways, as for almost every ransomware nowadays, remains spam emails. These emails distribute the malware as attachments. Malicious code can be inside the body of the emails instead. Opening such emails could be more than enough to infect a computer with the ransomware.

Social media sites and file-sharing services are the other distribution ways that may pose a risk. Malware-related files could be hidden around them. Preventing infection is doable by not downloading, opening or clicking anything suspicious.

TrueCrypter Ransomware – Closer Look

TrueCrypter a new ransomware, and it shouldn’t be confused with the encrypting program TrueCrypt.

The ransomware connects to remote locations and then shutdowns processes of Windows. This is a list of these processes:

  • antilogger
  • netmon
  • taskmgr
  • wireshark
  • charles
  • fiddler
  • reflector
  • sbiectrl

TrueCrypter creates two files in the %AppData%\Microsoft\TrueCrypter\ directory. One of them is an executable file by the name of TrueCrypter.exe. The other is a .xml file of the same name.

You can see a picture of the executable down here:

After the creation of the files, the ransomware makes entries in the Windows Registry. Those entries are made to ensure the malware will launch with every boot of Windows.

The registry entries are the following:

→HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\”TrueCrypter” = “%AppData%\Microsoft\TrueCrypter\TrueCrypter.exe”

and the following three afterward,

→HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\”EnableLUA” = “0”

→HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\”PromptOnSecureDesktop” = “0”

→HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\”ConsentPromptBehaviorAdmin” = “0”

Besides the initially created files, a warning message appears on your Desktop, and it reads:

If you see this text, probably your computer got encrypted by TrueCrypter. This means all your important files (documents, images, etc.) are now unaccessible and you will lose them forever unless you pay a sum of money to get your decryption key.

The decryption key uses the RSA-2048 algorithm, impossible to crack. Your files will be lost forever without paying.
If you don’t care about your files, just uninstall this software.
If you lost the application because your antivirus deleted it, or you need help, you can contact us on our email:

(You only have 72 hours before your private key will be destroyed, hurry up if you want to save your files!)

You can complete the payment in two ways including in BitCoins or with an Amazon Gift card. There are details in both the executable and instructions files. The payment amounts to around 100 dollars in BitCoins or 115 dollars if the Amazon method is used.

Paying, no matter what method you use, is NOT advised. Not only your files may remain locked, but you could also give inspiration to the cyber crooks to create more nasty ransomware. If they receive enough money, they also might make a new variant of the current ransomware that is tougher.

The TrueCrypter ransomware locks files with nearly sixty different extensions. RSA-2048 algorithm is implemented as the encryption process. The extensions that the ransomware can lock are:

→.docm, .docx, .dotm, .dotx, .gzip, .html, .index, .java, .jfif, .jpeg, .json, .litcofee, .pages, .php3, .php4, .php5, .7zip, .aspx, .bash, .bookmarks, .class, .config, .csproj, .phps, .phpt, .phtml, .potm, .potx, .ppam, .ppsm, .ppsx, .pptm, .pptx, .prproj, .psm1, .resx, .scpt, .shtml, .sitx, .sldm, .sldx, .splus, .sqlite, .sqlite3, .swift, .tar.gz, .thmx, .tiff, .vcxproj, .xcodeproj, .xhtm, .xhtml, .xlsx, .zipx

The extensions list might be incomplete as this ransomware still perseveres. After file encryption, all files will have the extension .enc – an extension used by the Cryptohasyou Ransomware too.

The TrueCrypter ransomware shuts down so many key processes in Windows, such as the Task Manager, so Shadow Volume Copies might be erased from the operating system as well.
