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:	108

Hancitor is a backdoor Trojan that downloads and installs other threats, such as backdoor Trojans and spyware. It often uses spam emails for compromising its targets after they open associated attachments and enable 'advanced content,' like a Word macro. Users can update their software and scan new downloads for in-advance protection, and an advanced anti-malware product should eliminate Hancitor infections safely.

A Download by Any Means Necessary

Trojan downloaders are an often-necessary go-between for greasing the wheels of Trojan distribution that cause crimes that range from file-locking extortion to hijacking bank accounts. Some residents of this classification, however, are more long-lived than others, and Hancitor is a notably seasoned case of such a Trojan. Throughout the years, it also provides the security industry with many demonstrations of the different exploits in use for infecting victims – but, usually, always starting from the same point.

Nearly all Hancitor attacks start with an e-mail message that includes either a link to a file or an attachment, which it misrepresents as being a Paypal invoice, a delivery notification, etc. The threat actor's goal isn't only getting victims to click the file, but to enable the additional content that contains exploits for loading Hancitor. Some of the techniques that malware experts are verifying include:

Copying a native Windows DLL file and using it for generating a new process and 'hollowing' it by injecting Hancitor's code.
Calling the Windows API of CallWindowProc and loading shell commands.
Using a resource enumeration function for loading the same commands.
Hiding segments of code in an embedded image's header.

Many of these strategical advantages focus on countering the PC security industry's wares and researchers. However, some techniques, such as having the fake document set its drive-by-download code's font size to 1, orient themselves at tricking imperceptive users.

Cutting Drive-by-Downloads Off at the Knees

None of the delivery methods for Hancitor change its intended payload, which, in most attacks, focuses on either data-exfiltrating spyware or backdoor Trojans that let threat actors control your computer. Both the Pony botnet's bots and Vawtrak banking Trojans will exploit Hancitor's downloading capabilities for loading themselves onto vulnerable PCs. Their consequential attacks can include keylogging, or recording your keyboard input, form-grabbing credentials like passwords, cryptocurrency mining, or man-in-the-browser attacks that redirect you to phishing sites.

Many of the above security issues will endanger your information and bank accounts directly. Correspondingly, victims of any Hancitor infection should speak with their bank and credit card companies for additional recommendation and be ready for changing all passwords, security questions, etc. Symptoms of Hancitor infections, or its related threats, may or may not be self-evident.

Anti-malware programs of most brands should provide coverage against the document-based exploits in use here. They also should delete Hancitor while scanning your PC, although updates may be necessary for counteracting the latest versions of the Trojan, presuming any new obfuscation.

Even if you don't know it, Hancitor gets onto your hard drive with your help. Without people opening things that they shouldn't, all of its technological trickery would be in vain.
