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.

HPmal/Zbot-C is a variant of Zbot Trojan that affects financial institutions based in Canada involving a company that processes payments from Point Of Sale devices and credit and debit cards. HPmal/Zbot-C will gather login credentials inserted into forms and embed a code into the websites so that attacked computer users reveal more information such as answers to secret questions, PIN numbers and mother's maiden name. HPmal/Zbot-C grabs the screen, accesses form field and logs keystrokes to gain information on the corrupted machine. A screenshot is captured each time the computer owner clicks the left mouse button while surfing the payment processing website. Each screen capture is focused on the mouse button and is sent back to the botnet owner. Form data is also gathered and sent back, incorporating usernames and passwords. The configuration files of HPmal/Zbot-C also involve a section called 'Keylogger processes' that provides a list of processes from which key strokes will be logged. Every time the attacked PC user enters usernames, passwords and card details into one of the programs all the keystrokes will be sent back to the botnet owner. Together with programs used for remote access such as SCP, Putty, GotoMyPC, VNC, and PCAnywhere, there are process names such as '*pos*', '*store*', '*sales*' and '*merchant*' that are possibly related to processing payment card data. HPmal/Zbot-C also attacks financial programs such as Quickbooks and Sage.
