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:	46

Bebloh is a banking Trojan that reconfigures your PC to allow for the theft of information related to your bank accounts, along with the possibility of third parties using Bebloh for other, equally illicit purposes. Since Bebloh is a high-level threat with multiple avenues for attacking any Windows PC, you should remove Bebloh with dedicated anti-malware software while taking into account the potential for its installing additional threats. While not mandatory, malware researchers also would recommend your contacting your bank on any extra steps to take for preserving your account's safety.

Bebloh: Exploring Your Bank Account through Internet Explorer

Bebloh is a multifaceted threat that includes functions for downloading other threats and opening backdoor connections to multiple servers. However, these side functions are primarily support for Bebloh's central attacks, which focus on subverting your Web-browsing experience in ways that directly compromise your bank accounts or their funds. In this respect, Bebloh takes the unusual step of specializing in Internet Explorer, and may force your PC to launch IE whenever you try to launch a different browser (such as Opera or Chrome).

Similar to other, specialized financial Trojans like Cridex, Bebloh targets the websites of a relatively small range of banks. Nevertheless, this 'small' number is estimated to have an upper threshold of roughly one hundred different entities. Bebloh monitors your browser for keywords associated with these banks, and automatically records entered passwords, account names and other login data.

Besides giving third parties the means by which to abuse your bank accounts personally, Bebloh also may be used to transfer funds from those accounts. Bebloh's backdoor connection, which transfers commands from remote attackers automatically, provides instructions for this attack on a manual basis.

Exploring a Proper Resolution to Bebloh Attacks

Unlike some banking Trojans, which show symptoms within your browser, Bebloh doesn't inject additional HTML content that could allow perceptive victims to identify its attacks. However, you may identify Bebloh when attempts to launch other browsers redirect you to Internet Explorer. Changes to the Windows Internet Settings also may prevent you from using a proxy service. Finally, accompanying Registry modifications also are made during Bebloh's installation and will need to be removed when you remove Bebloh.

Deleting Bebloh with anything less than competent anti-malware software is discouraged, as malware experts rate the probability of Bebloh's being linked to other threats on the infected PC to be relatively high. Although Bebloh doesn't disable anti-malware tools automatically, Bebloh may be instructed to do so through its backdoor connection, or install other threats with additional, anti-security features. However you choose to uninstall Bebloh, care should be taken to secure any leaked passwords or other information associated with your bank accounts.

Bebloh most often targets German bank users and associated websites, such as those designated with the domain suffix '.de'.
