Threat Metric
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.

Hydraq is a Trojan that opens up a backdoor for malware to enter the system and has received media attention due to its connection with the cyber attack on Google. The hack attack targeted Gmail accounts of human rights activists who were involved in China rights issues. Hydraq may infect a users computer through a document attachment of a spam email message or an unpatched vulnerability in Microsoft's Internet Explorer. Once Hydraq has installed on a compromised computer, it uses a backdoor to listen for incoming commands, which allow Hydraq to generate malicious tasks.
Hydraq permits the attacker to carry out the following malicious tasks: modify the registry subkeys, delete files, execute and modify attributes, reboot or turn of the computer, alter token privileges, read and delete the %System%driversetcnetworks.ics file, and erase all system event logs. Hydraq also inspects if %System%acelpvc.dll is present so it can load it and call its EntryMain() export.
Hydraq attachs itself as the system service RaS[FOUR RANDOM CHARACTERS] and its "ImagePath" value is made to begin svchost.exe. To get svchost.exe to know the existence of Hydraq and be loaded, Hydraq adds its service name into the list of service names stored in the "netsvcs" value of the registry key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSvcHost.
Hydraq can generate a copy of itself under a random filename in the %TEMP% directory or under the name %TEMP%c_1758.nls. We recommend that you obtain patches to fix Microsoft vulnerabilities and keep security software up-to-date.
