Spora ransomware started spreading worldwide

At the beginning of 2017, malware researchers spotted a new file-encrypting virus – Spora ransomware. It started spreading in Russian-speaking countries such as Russia, Kazakhstan, Belarus, and others. It seems developers had tested the grounds and now started spreading this piece of malware worldwide.

Recently, ransomware started attacking computer users living in the Netherlands, Austria and Saudi Arabia.One of the main reasons why Spora virus is supposed to be a dangerous cyber threat is that it does not need the Internet connection for data encryption. After infiltration it scans the system looking for targeted file types and encrypts them using RSA algorithm.

During the encryption process, malware generates two keys – public and private. Malware uses the public key for data encryption, and the private key is necessary for decryption. It would be standard encryption strategy; however, developers decided to encrypt the private key with AES cipher. In the ransom note, left after the encryption, developers of the Spora malware offers victims to purchase the private key and restore damaged files.

Sadly, it may seem like the only option for those who does not have data backups. Additional data recovery methods may not be effective because ransomware deletes Shadow Volume Copies, disable Windows Startup Repair, and even changes BootStatusPolicy.

Following data encryption, Spora virus drops a .html and .KEY files in each folder that includes encrypted files. The HTML file is a ransom note, where hackers explain about data encryption and suggest visiting the payment website. Indeed, hackers worked harder and made an advanced payment website that offers several services. Usually, victims are just asked to transfer particular amount of money.

However, this time people can choose what services they want: Spora removal, data recovery, immunity for the ransomware attacks or a full package of the services. The prices and the size of the ransom may vary from victim to victim according to the importance and amount of the encrypted files.

When malware started spreading worldwide, the payment website was updated with new pages and functions. Now victims can find a 'Help' page, public communication window and the list of transactions. Hackers want victims to trust them, so they allow to test the decryption software and restore two files for free. However, we do not recommend trying this tool and paying the ransom. It may be just a trick to swindle more money from you.

That’s why we recommend you to remove Spora from the computer even if it means you lose your personal files. For virus elimination, you will need a reputable anti-malware software, such as Reimage, and our prepared instructions at the end of the article.

How can I get infected with ransomware?

Spora ransomware virus mainly spreads via malicious spam emails which include an obfuscated .docx file. When people open it, they receive and error message. Users may think that this Word file is simply damaged or corrupted after downloading.

However, it’s just a little performance. The malicious email includes the HTA file, and when users open it, they execute and extract JavaScript file. Once this ‘closed.js’ file is dropped and executed on the system, the data encryption process starts.

What to do after Spora ransomware attack?

Spora malware is a dangerous and complicated virus, so it must be treated properly. Therefore, trying to remove it manually is not recommended. Instead of malicious files, you can delete important system file. This complex cyber parasite can hide under various file names and file types, so it’s nearly impossible to remove Spora manually.

However, we do not mean that you should take your PC to the IT specialist. It’s enough to rely on professional malware removal tool, such as Reimage, Malwarebytes Anti Malware or Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus. Install one of these programs, update it and run a full system scan. However, automatic Spora removal may not be smooth. Malware can prevent you from accessing security tools. In this case, follow the instructions below.
