Shadow ransomware. Decrypt & remove .shadow extension.

Shadow ransomware. Recently a new strain of the uncommon ransomware under the abbreviation BTCWare was released unto unsuspecting users of the web, uncovered by Michael Gillespie from ID-Ransomware. This new type of ransomware was observed to add new elements to encrypted files, through the extension .Shadow.

The strains under BTCWare specialize in infiltrating computers that were using weak passwords, by the use of Remote Desktop clients. As access is gained to the computer, ransomware is installed, followed by an encryption of the computers sensitive files.

The current outlook indicates no possible way to decrypt the files without purchasing a software. The hackers behind the BTCware ransomware have been reported by victims to have sent decryption keys to select victims, whose encryption software were outdated (Note: Newer versions of the encryption software have not yet been decrypted through this method).

The software used for encrypting files have stayed the same in the newer versions of the ransomware. The added updates, that we have found so far, include a new “ransom note” . In the note there can be found instructions for the victim to contact the address [email protected], to which payment is paid by the victim, in exchange for a decryption key to the locked files. In addition to the new note there is a new extension to the encryption data. In the newest versions of the ransomware a different type of encryption key was also used, namely the public RSA key (used for encrypting AES).

The ransom note is as follows:

All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail [email protected]
You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment we will send you the decryption tool that will decrypt all your files.
Free decryption as guarantee
Before paying you can send us up to 3 files for free decryption. The total size of files must be less than 1Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)

How to protect against ransomware is most frequently asked questions in the past year. Since ransomware has become the biggest threat among all viruses, people ask themselves if there’s a way to protect from such. It is already too late if you once suffered ransom attack and file has been locked. For some there is a solution but for others disappointment. Either way popularity of ransomware rises and new development are presented every day.

In general there are three types of ransomware reported as of this time.

  • Lockscreen ransomware – Rather than encrypting files, this type of ransomware will display full-screen message that prevents user from accessing the system. In order to restore access the ransomware will ask user to pay a fee.
  • Encryption ransomware – This type of ransomware will encrypt files. Encrypted files will be locked and user will no longer able to open them. The ransomware developer will ask user to pey in order to unlock, decrypt files.
  • MBR locker ransomware –  This ransomware will rewrite Master Boot Record and prevents user from accessing the system. After a reboot a message will ask users to pay a ransom to unlock PC.

What can we do against the battle with ransomware?

  • If you are already infected do not pay the ransom! Remove the virus and look for other solutions rather than paying. Paying the ransom may be your only option if you have really valuable data. However we do not recommend doing this because you will support the work of criminals. The risk of losing money and still stuck with encrypted files since there is no guarantee in any way that you will recover what one is lost.
  • Security researcher are always working on recovery solutions. Not all ransomware are professionally developed and being cracked, but some are so good developed that there is no current way to be beaten at the current date. One of the solutions is system restore.
  • Best solution is if you have a backup, wipe your hard drive and perform system restore. If not, backup your data frequently. Store backup data in any removable storage device or use any online backup services.
  • Protect your computer with antivirus, internet security, anti-malware software or new developed applications like anti-ransomware. Highly recommended is to keep it up to date and use the paid surveys. We do not recommend free applications.

Now that you have been infected you have a few options:

Many suggest that you simply pay and hope that you will get all off your data back. However in this case you risk losing money and still being stuck with crypted files. We do not recommend this way simply because you will support the work of hackers and the more money they get the stronger they will become.

The best option for you is if you have a backup, wipe your hard drive and perform system restore.

Use any type of anti malware software to remove Shadow ransomware.

NOTE: In this option the virus will be removed but the files will remain locked! You have to decrypt your files.

New research discovery shows how ransomware deletes files and substitute encrypted copy of them. It is not guaranteed, but it is a possibility that you may recover your files with data recovery software. Before trying to decrypt any files you can scan your computer for possible data loss.
