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.

The ChewBacca Malware, sometimes referred to by the alias of Trojan.Win32.Fsysna.fej, is a spyware program that records keyboard input, most likely to capture passwords and other private information that could be exploited by criminals. Computers compromised by the ChewBacca Malware infections aren't required to show any corresponding symptoms of these attacks, and the ChewBacca Malware also uses anonymity-based means of protecting its servers that make a shutdown unlikely to occur in the near future. Although the ChewBacca Malware's distribution currently is at low numbers, malware researchers recommend that you keep it that way with updated anti-malware products that can detect and remove the ChewBacca Malware without any issues.
The ChewBacca Malware: the Silent Roar of a Thief
The ChewBacca Malware, named for the Star Wars-referencing login menu accessed by its criminal developers, is one of the newer spyware programs to be identified. Although its functions are limited compared to complex threat platforms like Zeus, they're also highly effective at their goals, which involve stealing information while protecting the criminals who are using the ChewBacca Malware software. Unfortunately, the ChewBacca Malware's distribution methods still remain in the dark, and malware experts estimate that the ChewBacca Malware either is intended for niche use or has yet to be distributed en masse to criminal clients willing to use the ChewBacca Malware.
The ChewBacca Malware's primary characteristic, and the one for which the ChewBacca Malware is classified as a spyware program, is its keylogging function. This is similar to the keylogging attacks of PC threats like the LoverSpy Malware, EvilGrab, the Korplug Trojan and, of course, Trojan Zeus. Once the ChewBacca Malware is active, the ChewBacca Malware records the PC user's keystrokes to a log file and is uploaded to a hard-coded server. This lets the ChewBacca Malware easily steal any typed information, such as login names or passwords.
The ChewBacca Malware also is one of the still relatively few Trojans to utilize Tor, an anonymity-providing service that reroutes network communications. Although this does protect the ChewBacca Malware's servers and any criminal users, it also has some limitations, such as making it more likely that other PC security companies will be able to identify the ChewBacca Malware through changes in the Tor network, as well as complicating the ChewBacca Malware's networking activities. Unfortunately for the ChewBacca Malware's victims, these limitations aren't enough to provide any major problems for its keylogging attacks.
Quieting the Sound of a Spy on Your Hard Drive
While the ChewBacca Malware, somewhat ironically, asks its criminal users to 'hear me roar,' malware researchers certainly consider 'hearing' the ChewBacca Malware to be a good idea – since an undetected ChewBacca Malware may pilfer any typed information with ease. Because the ChewBacca Malware is a spyware program and, like all of its ilk, tries to prevent the user of a compromised PC from noticing the ChewBacca Malware, anti-malware software usually may be needed to detect the ChewBacca Malware. Once the ChewBacca Malware is detected, disabling the ChewBacca Malware through any means needed and then deleting the ChewBacca Malware immediately is the obvious and highly recommended solution.
The models of distribution for the ChewBacca Malware still are being examined, although malware experts can confirm that there are no signs of its being distributed for rent to other criminals than the development team, which is one of the most common business models for spyware operations. Till new information arises, protection from the ChewBacca Malware should take all of the general forms that malware experts always would recommend, such as disabling scripts, avoiding risky websites, updating your software and scanning files before opening them.
