Remove Spora Ransomware and Restore Your Files (Update June 2017)

Remove Spora Ransomware and Restore Your Files

This article will help you to remove Spora ransomware efficiently. Follow the ransomware removal instructions provided at the end of the article.

Spora is the name of a ransomware virus, that is meant to primarily target Russian speakers as its payment page and ransom note are written in Russian. However, other users may become victims as well. Your files will become encrypted with a very strong mixture of the AES and RSA algorithms. Afterward, the Spora cryptovirus displays a ransom message with demands for payment. See all specific Spora Virus updates below.

Threat Summary

Short DescriptionThe ransomware encrypts files on your computer machine. Then it displays a ransom note in Russian, although the language can be changed to English.
SymptomsThe ransomware will encrypt your files with the help of RSA and AES encryption algorithms.

Spora Ransomware – Ways of Distribution

Spora ransomware could be distributed by different ways. The payload file that drops the file with the malicious script (which uses both JScript and VBScript scripting languages) for the ransomware which infects your computer device is the following:

  • Скан-копия _ 10 января 2017г. Составлено и подписано главным бухгалтером. Экспорт из 1С.a01e743_рdf.hta

The .hta file is contained inside a .zip file attached to an email which looks like the following:

The email is written in the Russian language and a rough translation in English reveals that the email is lying to the user, in order to get him to download the attachment. The translation in general states that some “application has been accepted and processed, and two bills are attached – one with a deposit, the other without and to pay attention to the correctness of dates and details”.

The .hta file has been processed through the VirusTotal service and you can preview the results in the screenshot below:

Spora ransomware might also be distributing that payload file on social media sites and file-sharing networks. Do not open files right after you have downloaded them, especially if they come from suspicious sources like emails and links. Instead, you should first scan them with a security tool, check their size and signatures for anything unusual. You should read the ransomware prevention tips topic in the forum section.

SPORA Virus – June 2017 Update

Spora ransomware is still being spread worldwide. New malware samples have been discovered by researchers that have been obfuscated scripts. For example, there is a sample that pretends to be a needed font for Google Chrome. Once that executable is launched, a computer becomes infected. What is different from before is that Spora now uses a new infection chain scheme along with a new thread execution that use the Explorer process in Windows. What is more, the virus now has many threads for self-deletion of its processes. All of the things mentioned above proves that Spora keeps growing and evolving.

SPORA Virus – May 2017 Update

Spora ransomware has continued to evolve, but not as much in it’s activity after it infects, but more in the methods it uses to infect. One of the methods used by the virus, as of late reports is via a pop-up that is displayed solely on Google Chrome. This pop-up leads to a compromised website. From this website, a malicious EITest injection occurs which causes the pop-up to occur. The website looks like the following as reported by

As soon as the site is opened, it immediately injects a malicious script, and it causes a forced download of a malicious .exe file, named “Chrome font.exe” after being clicked on. If opened, the executable runs an infection malware which is intermediary and causes the download of the malicious Spora ransomware files. This is a new and unique social engineering scheme, but it does not mean that the virus has stopped using the RIG 4.0 exploit kit version which was reported to be associated with the IP The latest version 4.0 of the exploit kit is used in many other ransomware viruses like HELP_HELP_HELP Cerber ransomware, CryptoShield ransomware and Locky .osiris virus. The exploit kit is still used and still causes infection on computer systems that are not properly secured.

Spora Ransomware – Technical Information

Spora ransomware is a sophisticated cryptovirus. What makes it so is its strong encryption which has a few layers and uses different encryption algorithms and techniques. Different malware researchers say that the cryptovirus is mainly targeting Russian users and its name is also Russian (“Spora – meaning Spore). The ransomware will encrypt files on your computer system without changing the names of the files.

When your files are being encrypted, the fake documents will display errors to simulate corrupted documents, so you don’t suspect that something is amiss:

Spora ransomware could make entries in the Windows Registry to achieve persistence. Those registry entries are usually designed in a way that will start the virus automatically with each launch of the Windows Operating System.

The ransom note will be dropped on your Desktop. Once you enter your ID, you will be redirected to one of several domains with a payment page. On those domains you can navigate through and see the payment details. The ransom note will have the name of your ID and use the extension .html. You can check out the ransom note in the screenshot below:

That ransom note reads the following:

All your work and personal files were encrypted
To restore data, obtaining guarantees and support,
follow the instructions in your account.


Personal Area

What happened?
1. Only we can restore your files.
Your files have been modified using RSA-1024 algorithm. Reverse recovery process is called decryption. This requires your unique key. Choose or “hack” it is impossible.
2. Do not turn to intermediaries!
All recovery keys are stored only in our country, respectfully, if you someone will offer to restore the information, in the best case, he first buys the key at us , and then you sell it at a premium .

The cybercriminals who are behind the Spora virus have put demands and detailed instructions on the payment page, which you can see below:

You should NOT in any circumstance pay the cyber crooks. Your files may not get recovered, despite the guarantee given on the payment page. Moreover, giving money to those criminals will probably just motivate them further to pursue a career in cybercrime.

Below you see the complete list with file extensions that the Spora ransomware seeks to encrypt:

→.xls, .doc, .xlsx, .docx, .rtf, .odt, .pdf, .psd, .dwg, .cdr, .cd, .mdb, .1cd, .dbf, .sqlite, .accdb, .jpg, .jpeg, .tiff, .zip, .rar, .7z, .backup

A .KEY file will be created with a sophisticated technique, using a couple of encryption algorithms:

  • Generates the AES and RSA keys
  • Encrypts the RSA key using the AES one
  • Encrypts the AES key using a public key embedded in the .exe file
  • Stores both keys inside the .KEY file

Then, every file will get encrypted by the following structure:

  • Generates an AES key
  • Encrypts the AES key using a generated RSA key
  • Encrypts a file by using the AES key
  • Stores everything to each file

That process is repeated quickly in succession to all files, which have extensions that the ransomware searches to encrypt. After the encryption process is finished the files’ names will remain intact with no extra extensions or other affixes being added to them.

The Spora cryptovirus is reported by researches to delete the Shadow Volume Copies from the Windows operating system, disable Startup Repair and modify the BootStatusPolicy by utilizing the following command in the Windows Command Prompt service:

→process call create “cmd.exe /c vssadmin.exe delete shadows /all /quiet & bcdedit.exe /set {default} recoveryenabled no & bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures”

Read on to see some ways with which you might potentially be able to restore some of your files.
