What is GetCrypt ransomware? And how does it execute its attack?

GetCrypt ransomware is a new file-encrypting virus that can leave files inaccessible. It was first discovered by an exploit kit researcher, nao_sec. According to security experts, it is being installed through malvertising campaign that redirects users to the RIG exploit kit which has malicious scripts that will try to exploit any found vulnerabilities on the computer. If successful, it will download and install GetCrypt ransomware. It was found that it checks if the Windows language in the computer is in Ukrainian, Belarusian, Russian or Kazakh. If the computer is using any of the aforementioned languages, GetCrypt ransomware will terminate and won’t encrypt the files in the computer. However, if it isn’t running any of these languages, it will infiltrate the system. After it gets installed, GetCrypt ransomware will start to execute its attack by encrypting all the files in the affected computer except for the ones that are located under the following locations:

  • :\$Recycle.Bin
  • :\ProgramData
  • :\Users\All Users
  • :\Program Files
  • :\Local Settings
  • :\Windows
  • :\Boot
  • :\System Volume Information
  • :\Recovery
  • :\AppData

Based on the analysis done on GetCrypt ransomware, it utilizes both the Salsa20 and RSA 4096 encryption algorithms and when it encrypts files, it appends a 4-character extension and while encrypting files, it also creates a ransom note named “# decrypt my files #.txt” in each folder where there are encrypted files. This ransom note contains the following message:
“Attention! Your computer has been attacked by virus-encoder!
All your files are now encrypted using cryptographycalli strong aslgorithm.
Without the original key recovery is impossible.
It is in your interest to respond as soon as possible to ensure the restoration of your files.
P.S only in case you do not recive a response from the first email address within 48 hours, please use this alternative email address: [email protected]

  1. Open your browser
  2. Write to our mail: [email protected]
  3. Attach the encrypted_key.bin from %appdata% to your message”

Moreover, GetCrypt ransomware also changes the desktop wallpaper of the infected computer and will try to encrypt files on network shares. During the encryption process, it utilizes the “WNetEnumResourceW” function to enumerate a list of available network shares. And if it isn’t able to connect to the network share, it will use an embedded list of usernames and passwords to brute-force the credentials for the network shares and mount them using the “WNetAddConnection2W” function.
If you happen to be one of the victims of GetCrypt ransomware, there is a free decryptor made by Emisoft you can download to recover the encrypted files. You can get it here.
