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.

Ranking:	11,688

The Dr Jimbo Ransomware is a file encrypting Trojan that may target dedicated servers, but also can impact personal-use computers. Its attacks continue with the standardized abuse of the encryption technology for blocking the machine's owner from any local files not required by the OS, with its con artists asking for Bitcoin ransoms to undo the Trojan's ill effects. Keeping a resilient system of backups and using anti-malware tools for uninstalling the Dr Jimbo Ransomware is, nonetheless, still a better response.

By and large, Trojans focusing on encryption as a ransom method tend to be found on machines intended for personal activities or the projects of a single worker. However, innovations in threats aren't only found in their code, but in their philosophy of deployment, including which systems are targeted preferentially. The Dr Jimbo Ransomware shows a possible new era for ransomware-styled threats: attacking network servers.

The Dr Jimbo Ransomware's payload includes encryption using an unidentified algorithm (most likely a combination of Rijndael and RSA) to modify targeted data formats, excluding essential program ones. The Dr Jimbo Ransomware also appends each file with a new '.encrypted' extension for visual identification. Last, some samples of the Dr Jimbo Ransomware drop individual ransom notes as text messages, while others may generate a new ransom note for every single piece of encrypted data.

These instructions simply ask for e-mail communications on settling on a final Bitcoin price for decrypting your content. However, some the Dr Jimbo Ransomware messages do include threats of a two-day time limit on the ransom process, after which your data will be unrecoverable supposedly. Perhaps most meaningfully of all, malware experts saw some samples of these notes addressing the reader as the operator of a server machine, providing significant clues on the campaign's most likely targets and infection vectors.

Compromises of business systems often start with e-mail spam or weak network login info. Using strong, rotating passwords and scanning unrecognized e-mail attachments are two of the security steps malware experts would rate as most useful for stopping common infection vectors in their tracks. Many e-mail messages intent on delivering threats to business entities will use disguises such as failed delivery invoices or messages specific to the organization's industry.

Although the Dr Jimbo Ransomware's messages do offer to decrypt a file freely as proof of the potential transaction, such 'free samples' do nothing to verify that the con artists will reciprocate any Bitcoin payments in turn. For dealing with most file encryptors, malware experts advise solutions not dependent on the largesse of threat authors. In particular, backups stored on non-compromised drives, including portable devices and cloud services, can make the point of decryption moot.

Even though the Dr Jimbo Ransomware's preferred targets are relatively unorthodox, dealing with it doesn't require any specialized tools beyond those used for most types of harmful file encryptors. Remove the Dr Jimbo Ransomware with your preferred anti-malware solution and restore all files from a backup to make the 'ransom' half of this Trojan's campaign a transaction with all the substance of vaporware.
