Threat Metric

The Threat Meter is a malware assessment that SpywareRemove.com's research team is able to give every identifiable malware threat. Our Threat Meter includes several criteria based off of specific malware threats to value their severity, reach and volume. The Threat Meter is able to give you a numerical breakdown of each threat's initial Threat Level, Detection Count, Volume Count, Trend Path and Percentage Impact. The overall ranking of each threat in the Threat Meter is a basic breakdown of how all threats are ranked within our own extensive malware database. The scoring for each specific malware threat can be easily compared to other emerging threats to draw a contrast in its particular severity. The Threat Meter is a useful tool in the endeavor of seeking a solution to remove a threat or pursue additional analytical research for all types of computer users.

The following fields listed on the Threat Meter containing a specific value, are explained in detail below:

Threat Level: The threat level scale goes from 1 to 10 where 10 is the highest level of severity and 1 is the lowest level of severity. Each specific level is relative to the threat's consistent assessed behaviors collected from SpyHunter's risk assessment model.

Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.

Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.

Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.

% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.

Threat Level:	2/10
Infected PCs:	80

First Seen:	September 29, 2024
OS(es) Affected:	Windows

The ShiOne Ransomware is a Trojan that locks your media using an asymmetric combination of the AES and RSA keys. This secure encryption method prevents you from opening data, such as documents, until you decrypt each file with an appropriate decryption application. Users with valuable files should keep backups of them as protection against this attack and use fully-updated anti-malware programs for removing the ShiOne Ransomware as quickly as possible.

Trojans Taking Care to Lock Your Files Up Tightly

Creative coding practices aren't necessary, and sometimes even detrimental, to building a threatening program that accomplishes all its intended attacks without any unexpected glitches. The ShiOne Ransomware is an illustration of how a potent Trojan can be very derivative of other works, like the RaaS DataKeeper Ransomware or creations of the My Little Ransomware builder, such as Honor Ransomware. By copying one of the most well-known data-locking techniques among file-locking threats, the ShiOne Ransomware guarantees that the files that it attacks will remain unusable indefinitely.

The first versions of the ShiOne Ransomware that malware experts found appeared no further than on the last month of 2017. The Windows-compatible, C#-based Trojan uses traditional file-locking behavior that it may bundle with ransoming attempts, such as pop-ups or text messages asking for Bitcoins for unlocking your data. The ShiOne Ransomware does still appear to be circulating as of March of the new year.

During its installation, the ShiOne Ransomware modifies the Registry by inserting a mutex for preventing multiple instances of the software. The ShiOne Ransomware also uses a hidden Command Prompt for collecting some system and networking information before loading its most signature feature: data encryption. The ShiOne Ransomware enumerates all the files on the local drives, filters out inappropriate ones based on their locations and formats, and locks the remainder with an AES and RSA combination of algorithms.

A thirty-two character 'salting' feature results in a unique form of encryption for each file that the ShiOne Ransomware attacks. This addition, along with other characteristics of its very conventional file-locking routine, keeps users from decrypting and unlocking their media by themselves. Malware experts also warn that, without bugs or database leaks related to the ShiOne Ransomware campaign, the development of free decryption software is improbable.

Don't be the One to Reward the ShiOne Ransomware's File-Ransoming Misdeeds

The ShiOne Ransomware is a strong candidate for a file-locking Trojan profiting from its attacks by selling the decryption solution for recovering the blocked files to any victims. Some of the related symptoms of such ransoming attempts and corresponding the ShiOne Ransomware infections that malware experts outline include:

Ransom notes, as text files or Web pages, may appear on your desktop or in the same folders as any encrypted content.
The ShiOne Ransomware may launch pop-ups including instructions for paying the ransom, as well as ransoming-themed UI, such as a Bitcoin wallet interface.
The ShiOne Ransomware may change your Windows desktop's wallpaper to a warning image.
Any backups not under additional protection can suffer from being deleted by the ShiOne Ransomware for ensuring that you can't recover your locked files via the old copies.

Securing your backups by appropriate protocols, such as password protection or detachable device management, can protect your file recovery options from a ShiOne Ransomware infection. Malware experts also recommend allowing your anti-malware software to defend against the most common infection vectors, like e-mail attachments that may carry this threat. Since its encryption isn't reversible necessarily, the deletion of the ShiOne Ransomware with such tools should be proactive.

The ShiOne Ransomware is a file-locking threat with little going for it that's not available to other Trojans. However, this attitude is as much a strength as it is a weakness, and shows the average PC user that a damaging, data-sabotaging action isn't as hard to cause as it is to cure.
