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:	9/10
Infected PCs:	45

Snifula is a banking Trojan that assembles account information related to various banks, particularly for regional, Japanese companies. Unlike some competing threats, Snifula includes functions for the theft of both actively-entered and previously-stored information, and also may disable some security features. Removing Snifula with anti-malware tools should be the priority of any PC user dealing with Snifula, after which malware experts also might suggest contacting all relevant banks for further advice on protecting your accounts.

Count Snifula Smells Your Bank Passwords

Snifula, also widely known by the name Ursnif, is spyware focusing on collecting information related to banking activities. Snifula's most widely-known campaigns focused on Japan, with an unusual emphasis on small, regional bank customers, rather than users of large chains. However, PCs outside of Japan also are at risk for being infected by Snifula, which implements a wide variety of generally-applicable attacks:

Snifula's components, including both files and Registry entries, are concealed via a threatening Windows driver.
Snifula may disable your default firewall service, SharedAccess (a Windows feature for sharing control of your PC remotely) or the Windows Security Center.
Snifula may inject its code into the processes of various Internet accessibility programs, including most Web browsers. These code injections let Snifula intercept data that may be transmitted by your PC, including login names and credit card numbers. The data then may be transferred to third parties remotely. Snifula also uses a second function specifically for gathering passwords.
While the above attack tends to be the one favored by most banking Trojans, Snifula also includes attacks meant to scan for saved data, such as information in the Protected Storage or Certificate Store. This attack allows Snifula to acquire information, even when the PC user doesn't type it.

Closing the Nose of a Browser-Sniffing Trojan

Although most browsers may be affected by different variants of the Trojan, some versions of Snifula Trojans specialize in targeting Firefox users. Whatever your choice in browser might be, Snifula displays minimal symptoms. Monitoring your network activity can provide some minor evidence of a potential Snifula installation. However, as noted in its stealth capabilities, you shouldn't expect to be able to identify Snifula's files, folders or other components visually.

You should respond to any potential installation of this banking Trojan by using updated, trusted brands of anti-malware tools to remove Snifula. Even if you uninstall Snifula immediately, malware researchers warn that you should assume that all stored passwords on your PC are potentially compromised and susceptible to enabling account hijackings (and similar hurtful actions). Changing your account passwords and related security data should be undertaken as soon as possible after Snifula's deletion.
