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.

Based on the same template as BKDR_VERNOT.A, BKDR_VERNOT.B is a backdoor Trojan that, like its close relative, uses a benign company's online data storage-based services to obfuscate the C&C server attacks, allowing BKDR_VERNOT.B to steal information and receive attack instructions with a minimal chance of being detected. In terms of the attacks that BKDR_VERNOT.B may launch against your PC, BKDR_VERNOT.B is as dangerous as any other backdoor Trojan, and SpywareRemove.com malware researchers heavily encourage using a trustworthy anti-malware application to delete BKDR_VERNOT.B before any sensitive information can be stolen.

When Blogging Goes Bad with a Hand from BKDR_VERNOT.B

Using a modified version of the same strategy that BKDR_VERNOT.A employed with Evernote, BKDR_VERNOT.B doesn't contact a malicious URL directly to use as a Command & Control server. Instead, BKDR_VERNOT.B contacts a Japanese blogging service, from which BKDR_VERNOT.B can upload stolen data (such as passwords or your system information), receive configuration instructions or process Web addresses from which BKDR_VERNOT.B can download and install other PC threats. Because the 'C&C server' that BKDR_VERNOT.B uses actually is a benign text-based service, some security programs may be unable to detect BKDR_VERNOT.B's attacks. SpywareRemove.com malware researchers also warn that BKDR_VERNOT.B will attempt to conceal itself from any direct observation by injecting itself into the memory process of another program.

The Vernot family's exploitation of unusual C&C server mechanics is innovative, but BKDR_VERNOT.B's major attacks still are in keeping with standard backdoor Trojan behaviors. SpywareRemove.com malware experts warn that BKDR_VERNOT.B is likely to be involved in part of or all of the following activities:

Downloading and installing other kinds of malicious software without your permission. Police Ransomware Trojans, specialized forms of spyware and rogue anti-malware products all are examples of BKDR_VERNOT.B's potential payloads.
Changing your computer's security settings in ways that reduce your safety both online and offline. Many of these changes may take place in the system Registry and may not display in other parts of your operating system's interface.
Renaming files arbitrarily.

The bulk of BKDR_VERNOT.B's functionality appears to be focused on downloading, unpacking, installing and launching a variety of malicious files. BKDR_VERNOT.B's logs, like everything else related to its behavior, are stored in its faux 'draft' blog entry.

Why You'd Better Not Let BKDR_VERNOT.B Get Away with Its Blogging Misdeeds

Due to the breadth of its overall backdoor functionality, BKDR_VERNOT.B can be complicit in highly-invasive attacks that steal confidential information or install high-level PC threats, and SpywareRemove.com malware researchers recommend removing BKDR_VERNOT.B as quickly as BKDR_VERNOT.B can be detected by any decent anti-malware application.

Since BKDR_VERNOT.B does take steps to reduce the chances of its being detected easily, SpywareRemove.com malware researchers also encourage updating your anti-malware software before you try to scan your PC for any possible BKDR_VERNOT.B infection. Keep in mind that since BKDR_VERNOT.B largely is dedicated to installing other PC threats, your system scans should be thorough and capable of detecting other PC threats that BKDR_VERNOT.B has a high chance of installing. BKDR_VERNOT.B's payloads may or may not show symptoms that will allow you to detect them once they're installed.
