Spora ransomware. How to delete? (Removal tutorial)
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.

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.
