Posted: December 21, 2015
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 '.him0m File Extension' Ransomware is a file encryptor; a Trojan that modifies your files with a data-scrambling algorithm that makes them temporarily unopenable. Even though the primary point of such a threat campaign is to ransom your files for money, malware researchers find it more efficient and affordable to use alternative means of restoring any lost files. Just as with all other high-level threats, deleting the '.him0m File Extension' Ransomware is a task to leave to your anti-malware programs, after which any data recovery can proceed.
An Extension You Never Want to See on Your Files
Recent campaigns from threats like the XRTN Ransomware, .vvv File Extension Ransomware and, now, the '.him0m File Extension' Ransomware show that threat authors are hoping that PC owners pay for more than their presents this Christmas season. Like the other types of file encryptors seen so far, the '.him0m File Extension' Ransomware scans your hard drives for files of specific formats, encrypts them, and delivers a ransom message for their theoretically safe return to their original formats.
The range of different files types being targeted is non-finalized, although there is no current evidence for the '.him0m File Extension' Ransomware targeting files that are essential to the infected PC's operating system. Besides encrypting the chosen files, the '.him0m File Extension' Ransomware also appends the titular '.him0m' type to them, which makes them visually identifiable without changing their actual formats. Victims of these attacks should note that changing the file name by removing the added extension is not a solution capable of reversing the data encryption, which rearranges fundamental file data (similar to a .ZIP archive).
Besides its actual attack, the '.him0m File Extension' Ransomware also deposits an image-based ransom message on your PC, and may lock your desktop to display this image. Its emphasis on using the Bitmessage client for all ransom communications shows how threat administrators are continuing to use peer-to-peer technology to obfuscate any attempts to track them.
Cutting Off the Extension of Ransomware Crime into Your Computer
Although the '.him0m File Extension' Ransomware shows many, basic characteristics in common with other file encrypting Trojans malware researchers haven't confirmed any association between this threat and past Trojans. The wide availability of ransomware creation kits in the threat industry does point to the '.him0m File Extension' Ransomware's 'business' model being one that's likely to continue being seen in the future, regardless of whether or not the '.him0m File Extension' Ransomware continues its development.
Protecting your files from the '.him0m File Extension' Ransomware doesn't require paying its ransom, and malware researchers typically find paying third parties an unreliable means of resolving their attacks. A '.him0m File Extension' Ransomware attack also may delete any local backups that are available. However, cloud services and removable storage drives can offer safe means of preserving your files and restoring them once you've deleted the '.him0m File Extension' Ransomware.
Although the '.him0m File Extension' Ransomware's distribution model is still under analysis, past file encryptors have favored online tactics for installing themselves, such as fraudulent e-mail attachments and concealed social networking links.
