File Spider ransomware targets victims from Balkans

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.

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 [ file-spider@protonmail.ch].” 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.
