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:	8/10
Infected PCs:	7

Win.Trojan.Ircnite-27 is a Trojan that installs other threats and may also include (or install other Trojans that include) backdoor capabilities that let criminals control your PC through remote servers. By its base functions, Win.Trojan.Ircnite-27 hardly is a unique snowflake, but malware researchers were impressed after a look at Win.Trojan.Ircnite-27's delivery system: an exploit kit that manages to install Win.Trojan.Ircnite-27 without using an exploit or even downloading any files. Because of the risks posed in its basic functions, Win.Trojan.Ircnite-27 is categorized as a high-level PC threat, and anti-malware programs should be entrusted with removing Win.Trojan.Ircnite-27 – just as your browser's security features should be used to block the attacks that install Win.Trojan.Ircnite-27 so deftly.

Win.Trojan.Ircnite-27: the Payload of an Exploit Kit... Minus the Exploit

Win.Trojan.Ircnite-27 is a member of a family of backdoor Trojans known for using Internet Relay Chat to handle the communications between criminals and the compromised PCs, effectively allowing the infected computer to be controlled for a variety of criminal activities, potentially including DDoS attacks, spamming or stealing personal information. However, what brought Win.Trojan.Ircnite-27 to the eyes of malware researchers wasn't what Win.Trojan.Ircnite-27 could do, but how Win.Trojan.Ircnite-27 was installed.

The host website for Win.Trojan.Ircnite-27 utilizes an unoriginal (but, still, barely-used) form of exploit kit-based attack that accomplishes the same effect as a drive-by-download... without the download. Unlike other exploit kits, this unreliable Web page doesn't detect your software and then use appropriate vulnerabilities to download a file. Instead, this Web page writes Win.Trojan.Ircnite-27's EXE file directly to your hard drive by using VBScript. This attack circumvents download-blocking security features – and SpywareRemove.com malware experts also caution that most of the standard defenses against other exploit kits aren't necessarily effective against the attacks being used to install Win.Trojan.Ircnite-27.
At the time of this article's writing, the associated Web page still is open and distributes Win.Trojan.Ircnite-27 to any visitors unlucky enough to load the site.

The Last Step Before Getting Roped into a Night with Win.Trojan.Ircnite-27

If there's a saving grace to the effective distribution method behind Win.Trojan.Ircnite-27, it's that most affected Web browsers may prompt you to run an add-on script before allowing the attack to continue on its course. This generic 'script runtime' alert may inaccurately identify the software as being from Microsoft, making it entirely possible that a victim may trust the program by default even as it proceeds to deconstruct their PC's security. Cautious PC users who only install programs from trusted sites and disable all scripts on sites that are potentially compromised should be able to dodge this attack without a Win.Trojan.Ircnite-27 infection.

SpywareRemove.com malware analysts can confirm that Win.Trojan.Ircnite-27 is designed for Windows but has a broad range of compatibility with both old and new versions of that operating system. Windows versions from XP up to at least Windows 7 all are at risk of Win.Trojan.Ircnite-27 infections, which don't have any symptoms – other than, hopefully, the warnings of relevant anti-malware programs before you remove Win.Trojan.Ircnite-27.
