NMoreira Ransomware

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 NMoreira Ransomware is a Trojan that encrypts your files and transfers the key to decoding them to a server. As with almost any file-encryption Trojan's attack, the NMoreira Ransomware blocks your data to collect ransom payments, although paying and recovering the lost data don't have a one to one correlation necessarily. PC users in Portuguese-speaking regions especially should follow the usual standards in securing their data and deleting the NMoreira Ransomware on sight with their anti-malware protection.

The Threat of 'Maktub' Strikes Back in Unanticipated Ways

Although superficial details like e-mail addresses, extensions, and the formats of messages can help identify the origins of a Trojan, they also can be misleading about its ancestry. As an example, malware experts recommend looking at the NMoreira Ransomware, a Trojan that adds the 'maktub' extension to the content it damages but has no relationship with the Maktub Ransomware. Instead, the NMoreira Ransomware's closest relative most likely is the AiraCrop Ransomware.

The NMoreira Ransomware uses Portuguese messages to communicate with any victims, a fact that's implicative of the Trojan targeting not just Portugal, but South American nations like Brazil. It uses an asymmetric, AES-based encryption function to encode content on the infected PC, such as spreadsheets, documents and music. As noted previously, the '.maktub' extension that the NMoreira Ransomware also adds to their names has no bearing on the Trojan's history and most likely is a superficial coincidence of branding.

With your content blocked, the NMoreira Ransomware demands ransom payments by creating text messages asking for additional e-mail contact. Victims can find these instructions on their desktops or in the same directories as any enciphered content, but malware researchers strongly discourage paying the fee.

When not to Pay for the Key to Your Belongings

Free decryption services for the NMoreira Ransomware infections have yet to appear, but may be possible, with further research by the cyber security industry. Until that time, PC owners can preserve their files by keeping their backups on password-secured servers or external devices. While malware experts can confirm that Portuguese-speaking nations are at high risk, they have yet to confirm the infection vectors this campaign is exploiting. Past campaigns of file-encrypting Trojans are notable for preferring spam e-mails.

Decryption isn't a service standard anti-malware products provide. However, removing the NMoreira Ransomware through the assistance of your anti-malware tools can stop the further infliction of harm on your saved work or close related security holes, such as unsafe network activity. Updating your anti-malware applications promptly also is a habit that malware experts emphasize to catch recently-detected threats of all kinds.

Whether it's part of a growing family or just a lone outsider, the NMoreira Ransomware stands as proof of the profit con artists find in taking someone else's files and changing them for the worse.
