Rush-ransomware-sensorstechforum-mainA virus, belonging to the HiddenTear project, named Rush has continued to infect user PCs, adding the .crashed file extension after it encrypts their files. The virus is almost identical with Sanction ransomware with differences being the name, encryption and file extensions used. Rush ransomware uses a strong AES cipher to encode files and demands a ransom payoff of 2 BTC after encoding the files. The ransomware drops a note explaining what happened. It also includes instructions on how to use anonymous networking to pay the ransom money. Security experts strongly advise against making any ransom payoff to the developers of this virus since this may not result in getting your files back and furthermore, you support the cyber-criminals.

Rush Ransomware – How It Spreads

This type of crypto virus is spread by different means. One of those is by utilizing expensive software to spread spam e-mails, containing a malicious attachment. If such file attachment is opened, the file will automatically activate scripts and drop Rush Ransomware on the infected PC. In some cases, malicious code may be directly written in the e-mail message itself.

Similar to other HiddenTear viruses, like Strictor or Sanction, Rush ransomware may spread in online places with file sharing capability. This group of sites includes file sharing websites, social networking sites and other online domains or programs which support file sharing.

Rush Ransomware – Detailed Information

This virus is put in the ransomware category by malware researchers. When it infects a given machine it may drop its files in different key Windows folders, for example:

  • %AppData%
  • %Roaming%
  • %Local%
  • %LocalRow%
  • %Windows%
  • %User’s Profile%

Rush ransomware is also the type of virus that may leave its executables under different names which can vary from completely random to names that are identical to legitimate Windows processes, for example, svchost.exe.

These executables may run when you start Windows. To do this, Rush ransomware may conduct modifications in the Windows Registry Editor. Such modifications may be done in the Run key:

HKLM/Software/Microsoft/Windows/CurrentVersion/Run/

As soon as its malicious encrypting module is ran, Rush ransomware may immediately begin to encrypt the following file types:

.adi, .adt, .altr, .arw, .asmx, .asp, .aspx, .csv, .doc, .docx, .dwf, .html, .jpg, .msg, .odt, .pdf, .php, .png, .ppt, .pptx, .psd, .qbb, .rpt, .sldprt, .sln, .sql, .txt, .xls, .xlsx, .xml

The encrypted files are appended the .crashed file extension, for example:

New Text Document.txt.crashed

After file encryption, Rush ransomware drops a ransom note, named DECRYPT_YOUR_FILES.HTML and it has the following:

“All your files have been encrypted with Rush Ransomware
Your unique GUID for decrypt ***
Send me some 2 BitCoin on address: {bitcoin address}
After confirming the payment, all your files can be decrypted.
If you do not make payment within five days, you will lose the ability to decrypt them, and all your files have been deleted
Make your Bitcoin Wallet on: https://www.coinbase.com/ or http://blockchain.info

After the payment, send the wallet from which paid and your unique ID to mail: [email protected]

The instructions point out to using bitcoin conversion websites in order to send and untraceable BitCoin payment to the cyber-crooks.

However, users are strongly advised to immediately remove this virus from their computer instead of complying with the cyber-criminals’ demands. Paying the ransom is no guarantee the files will be decrypted.
