ShiOne – a cyber threat that encrypts important files on the targeted computer

Image of ShiOne ransomware

ShiOne is a ransomware virus that is designed to encrypt files on the targeted computer. The malicious program uses a combination of RSA and AES encryption[1] to make documents, images, multimedia, archives, databases, and other popular data inaccessible.

ShiOne ransomware is written in C# programming language and generates data encryption keys offline. It means that they are added in the ransomware’s code before distributing the virus. Malware can be spread via malicious spam email attachments, infected ads, bogus download, etc.

However, once ShiOne virus enters the system, it modifies Windows settings, created new Registry entries and might install numerous components that are responsible for keeping ransomware on the computer and data encryption.

ShiOne uses symmetric and asymmetric keys to encrypt files on the affected computer. Following the complicated encryption procedure,[2] malware drops a ransom note where victims are asked to pay the ransom in exchange for decryption software.

However, we want to discourage you from transferring the demanded sum of money. This action might only increase your loss. Ransomware-type cyber threats are created for swindling the money only. No one can ensure you that cyber criminals actually have working ShiOne decryptor and let you use it after receiving your payment.

Instead of risking to lose your money, you should remove ShiOne from the computer. Virus elimination is needed to protect your machine from further cyber attacks or privacy-related issues. Also, while malware resides on the system, your PC is sluggish, and some of the programs might not operate properly.

As soon as you learn about ransomware attack, you should scan the system with reputable anti-malware software, such as Reimage. However, automatic ShiOne removal won’t help to recover your files. For that, you will need to use data backups or third-party tools. You can find some suggestions below.

Ransomware distribution methods and how to avoid it

Crypto-viruses can be distributed using numerous methods. The most popular way to spread file-encrypting viruses is spam emails that contain the attached document. Nevertheless, the attachment looks like ordinary Word, PDF or ZIP file; it is obfuscated and includes malware downloader. Once you click it, malware executable is dropped on the PC.

However, there are many other crypto-malware distribution strategies. Security specialists from[3] tell that users should be careful with software downloads or updates installation. Freeware, shareware and update alerts in pop-ups often include malicious content. Users are advised not to install any cracked or illegal content.

Additionally, authors of ransomware virus might take advantage of these distribution methods too:

  • malware-laden ads that might be placed on legit and high-risk websites;
  • exploit kits that take advantage of outdated software or operating system vulnerabilities;
  • drive-by downloads that trick users into installing fake browser extensions or software.

Security experts remind that even the most secure antivirus program cannot protect you from ransomware if you do not watch your activities online. Additionally, you should create backups of the important files in case of the cyber attack.
