What is File Spider ransomware?

File Spider ransomware targets victims from Balkans

File Spider virus ransom note

File Spider ransomware is a malicious program which aims to encrypt valuable information on the victimized computers to earn illegal profits[1]. After it reaches the system and encodes data, it demands to pay the ransom within 96 hours to receive a decryptor. According to the latest news, the ransomware targets people from the Balkans — Bosnia, Serbia, Croatia, etc.

However, security experts do not recommend following such orders. Criminals are not worth relying on because you might lose your money as well. Thus, after you have noticed .spider extension at the end of your filenames, you should focus on File Spider removal because it may have modified the system, opened a backdoor to other cyber threats and made your PC vulnerable.

File Spider ransomware is usually dropped on the system from the malicious MS Word document and executed using PowerShell. The virus on the system operates from two components. The one is an encryptor that arrives on the system as an enc.exe file. The second element is a decrypter and the main GUI that runs from dec.exe.

Following data encryption, ransomware shows a ransom demanding window called “File Spider [].” It includes a detailed explanation about data encryption and gives instructions what users have to do. The ransom note also provides a link to the video hosting site where the victims can find a video tutorial on how to decrypt the data.

The program has several sections that provide different information or guidelines:

  • Start Page;
  • Translate
  • Visit Website;
  • ID Code;
  • Decrypter;
  • Help.

In the Start Page, victims are threatened not to take any other action because File Spider malware is said to be capable of detecting them and deleting encrypted files as a punishment. However, it’s currently unknown if ransomware actually has this functionality. Though, elimination of the malware is still needed.

Nevertheless, cyber criminals try to be helpful and give even video tutorial how to access payment website; you should not follow their orders to avoid money loss.[2] Ransomware is used for swindling the money illegally. Thus, once they receive the payment; they might disappear and do not give the decryption key.

If you see this threatening window on your computer’s screen, you should reboot to Safe Mode with Networking and remove File Spider virus using reputable malware removal software, such as ReimageIntego.

Ransomware arrives as a decoy Office Word document

While crypto-malware can spread with the help of different techniques, this one particularly reaches the victim as a fraudulent email letter with the subject line Potrazivanje dugovanja, which means Debt Collection in English. The malicious letter holds Word document written in Bosnian language.

Once the inexperienced computer user opens the document it triggers the hidden macro code which launches PowerShell to download the payload of the ransomware from a free Java Script hosting site called At first, the payload is encoded with Base64.

To decode the malicious files, PowerShell script uses AlbertTI key in the XOR operation and saves the payloads inside the executables of the ransomware — enc.exe and dec.exe.

Therefore, malware researchers team from[3] warn that users have to be careful with downloads, updates, and ads because they might also be used for spreading the virus. Thus, you should not click or download any suspicious content online.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
