A new ransomware string has been detected by malware researchers, identifying itself as Spectre ransomware. The virus changes the names of the important files on the computers it infects to random and ads the .spectre file extension to them as a suffix. Then it drops a HowToDecryptIMPORTANT!.txt note file in which the cyber-criminals demand the sum of approximately 200$ to be paid in order to get back the encrypted files.

Spectre Ransomware – Distribution Methods

The .spectre file virus is a type of malware you do not want on your computer. It is by far the wors type – file encryption ransomware. However, many may have already fallen victims to this virus. In case you are one of them, bear in mind that there are several methods by which the Spectre virus may have infected your computer system. These methods are generally summed up by two spammed objects – malicious web links and malicious files. You may have seen such links on e-mail spam messages directed towards your computer system. These e-mail spam messages usually contain a false statement that the web link or e-mail attachment on them is a legitimate type of file. This attachment or link is usually portrayed as an invoice or other document. It may even be a compromised Microsoft Word document that has malicious macros in them and infects your computer when you click on the “Enable Editing” button. After this is done, here is what happens to your computer:

Other methods by which you could become a victim of the Spectre ransomware are via malicious files uploaded as fake setups, patches, updates, key generators, license activators and other software uploaded on shady sites you should not have trust.

Analysis of the .spectre Virus

When an infection by .spectre file virus has happened, the virus establishes connection to the following domain and host:

→ /a0142503.xsph{.}ru/systemlog.exe
141.8.195.157:80

From this host, Spectre ransomware’s loader script downloads the following types of files:

  • systemlog.exe – main executable which encrypts files.
  • HowToDecryptIMPORTANT!.txt

In addition to this, the ransomware virus also automatically may open it’s ransom note. It asks the victim of the virus to visit a Tor-based web page:

IMPORTANT INFORMATION!
All your files are encrypted by encryption algorithm AES-256, you can’t decrypt your files without a key.
If you want to decrypt your files you should pay 200$.
To decrypt your files go to a0142503.xspn{.}ru/login.php
your ID: {23412414}

When the web page is visited, the user sees the main ransom note screen of the ransomware virus, which is the following:

It advertises the so-called SPECTRE DECRYPTOR which decrypts the encrypted files. However, security experts strongly advise against paying the cyber-criminals behind this ransomware for 2 main reasons:

  • You may not get your files back.
  • You support them to further spread and develop their malware and infect more users.

Spectre Ransomware – The Encryption Process

The Spectre virus encrypts via the Advanced Encryption Standard algorithm with 256 bit of strength. This is by far the strongest stable AES cipher which is classified as a Suite.B algorithm for data security (one of the strongest). If properly implemented, there is little chance that it can be decrypted. The Spectre virus aims at the following file types

→ .avi, .bmp, .doc, .docx, .gif, .jpeg, .jpg, .mpeg, .pdf, .png, .ppt, .pptx, .rar, .rtf, .tiff, .txt, .wav, .wmv, .xls, .xlsx, .zip

If the virus detects those files on your computer, which are basically documents, media files, archives, text files, videos and others, it encrypts them by replacing data in the files. This makes the files seem corrupt and no program can open them. The virus does not stop there. Spectre ransomware also changes the names of the files themselves to custom names that consist of random letters, numbers and symbols.

The files assume the following appearance after they have been encrypted by Spectre:

Before actually removing this virus from your computer, we advise you to do a backup of your files.

After doing so, it is important to remove all files associated objects which Spectre ransomware has created on your computer. To do this, you can either manually look for the files by following the instructions below, or you can automatically remove Spectre ransomware.

After removing Spectre ransomware, it is recommended to focus on restoring your encrypted files with other methods, at least until a decrypter is released by researchers. We have suggested several tools with which you can recover your data. They are in no way 100 percent guarantee of you recovering all your files, but with their aid you may restore at least some of the files.
