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:	2/10
Infected PCs:	85

Backdoor.Makadocs is a backdoor Trojan that compromises your PC in an attempt to allow criminals to gain control over it. Backdoor.Makadocs attacks appear to be focusing on the populous country of Brazil, with Backdoor.Makadocs being delivered by a Trojan dropper that's disguised as a seemingly beneficial RTF document.

How Backdoor.Makadocs Subverts Google for an Easy Go-Between

Backdoor.Makadocs was identified in mid-November 2012 as a newly emerging Trojan that's designed to give criminals access to infected computers. Although the goal of this backdoor vulnerability is typical for Backdoor.Makadocs's subtype of Trojan, Backdoor.Makadocs's means of achieving it is unusual: Backdoor.Makadocs uses the Google Docs website as a proxy server between itself and its ultimate C&C server. This helps Backdoor.Makadocs avoid firewalls and security measures that would detect any direct contact between Backdoor.Makadocs and a malicious server, and can be an effective means of evading simplistic network security.

Backdoor.Makadocs infects new computers with a little assistance from Trojan.Dropper, a specially-crafted RTF file that's designed to exploit Microsoft Office vulnerabilities. These vulnerabilities are used to install Backdoor.Makadocs without any visible symptoms of the process. SpywareRemove.com malware researchers recommend that Brazilian PC users in particular be cautious around links to strange RTF files, given Backdoor.Makadocs's history of targeting that region preferentially.

Backdoor.Makadocs originally was compatible with Windows versions 95 up to and inclusive of Windows 7. However, an update to Backdoor.Makadocs also has given Backdoor.Makadocs compatibility with Windows 8 and Server 2012.
