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.

The RaRuCrypt Ransomware is a Trojan that locks your files using the WinRAR data-compressing application. Although its threat actors ask for a ransom to restore your media, their negotiating channel, currently, is defunct, due to Terms of Service violations. Anti-malware products can help block or uninstall the RaRuCrypt Ransomware to protect your files, and a variety of free options can help with restoring them.

The Ransom Attempt that's Getting Ahead of Itself

Threat actors without much in the way of state-level resources often resort to imperfect or inexpensive infrastructure for supporting their campaigns. While it's not always necessary to have a full-fledged botnet facilitating the attacks of, for instance, a file-locking Trojan like the RaRuCrypt Ransomware, the absence of such a network, sometimes, creates problems. The RaRuCrypt Ransomware's campaign already appears to have sabotaged its ability to profit via ransoms.

The RaRuCrypt Ransomware is a Russian program by Albert Mikhailovich (or 'Альберт Михайлович'), a new threat actor to the industry of file-locking Trojans. Similarly to the WinRarer Ransomware or the .7zipper File Extension' Ransomware, RaRuCrypt uses data-compressing freeware for locking the files of its victims. Its attacks target formats such as DOCs, JPGs, MP3s, and PDFs by placing each one into its own, individual RAR archive.

When it completes this file-locking attack, the RaRuCrypt Ransomware also generates a series of Notepad files in the same folders. The messages ask the users to pay 200 Russian rubles (equal to three and a half US dollars) for the unlocking password. However, the most diverging trait in the note is how its threat actors negotiate: via the VKontakte social media service. Malware experts note that the current profile that the Trojan promotes is already locked for Mikhailovich's breaking the website's ToS.

Digging Your Files out of Someone Else's Archives

The low-effort approach of the RaRuCrypt Ransomware's ransoming communications also encompasses the security, or lack thereof, of its encryption and file-blocking attack. Victims can run WinRAR and open their 'locked' files with the 'S?{DCO^C!{L@CR^+<7E}2' password, which is non-dynamic. Most file-locking Trojans use more secure cryptography, such as a combination of the AES and RSA algorithms for preventing this straightforward data recovery. The RaRuCrypt Ransomware is a 32-bit Windows program of under a megabyte, and malware experts aren't able to verify which infection methods Mikhailovich uses for distributing the Trojan. Typical cases of file-locking Trojan attacks, often, trace back to the user opening corrupted e-mail attachments, visiting a website hosting an exploit kit, downloading illicit programs, or using a network with a high-risk password (such as 'admin'). Anti-malware products provide features for protecting your PC against all but the last of these attacks and also can delete the RaRuCrypt Ransomware securely. Running a frugal Trojan campaign comes with different costs than financial ones. Despite its significant limitations, the RaRuCrypt Ransomware is a real danger to your files, and even the smallest patch could make known solutions to its attacks useless. Users should, accordingly, emphasize avoiding the infections and storing their media safely.
