'.duhust Extension' Ransomware
Posted: November 17, 2016
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 '.duhust Extension' Ransomware encrypts your local media files and creates instructions asking you to contact its perpetrators via e-mail to pay for a decoder. Decryption services purchased via ransoms tend to be unreliable and should be considered, if ever, only after trying every alternative. Like other file-encrypting Trojans, you can remove the '.duhust Extension' Ransomware before or after its encryption attack with most basic anti-malware solutions.
A New Problem Pops Up on the Globe
As threat authors do their best to reduce any unnecessary workloads and churn out new products capable of avoiding conventional security protocols, both individual and familiar Trojans are proliferating. The file-encryptor classification of Trojans has grown with examples like Hidden Tear, the Crysis Ransomware and the Globe Ransomware especially. For that last family, malware analysts recently found a new relative: the '.duhust Extension' Ransomware.
The '.duhust Extension' Ransomware utilizes digital encryption, a technique for reordering the internal data of files (such as the compression process seen in WinZip or WinRAR), to hold your content up for ransom. The attack makes the information thus affected unreadable by their applications, potentially depriving the victim of access to pictures, movies, local Web pages, or even, in the worst cases, executable programs. As according to its name, the '.duhust Extension' Ransomware also makes one other change to this content: a new '.duhust' extension, which you can find appended to the end of any extension already present.
The '.duhust Extension' Ransomware and other Globe Ransomware variants traditionally, but not necessarily universally, hijack the desktop wallpaper of the compromised system and use it for displaying a ransom-related image. The '.duhust Extension' Ransomware also may create text messages promoting an e-mail address that infected PC users should contact to buy a decryptor for their files, although malware experts often rate such tools as having undependable data recovery rates.
Sending the Globe Ransomware Spinning out of the Way
The standardized symptoms of the '.duhust Extension' Ransomware infections, while all high in visibility, also have the drawback of occurring after its encryption function. Instead of detecting this Trojan by eye, after it damages your media, malware experts endorse proactive security steps, such as anti-malware programs with a browser monitoring function. Regular rotations of sophisticated network passwords and scans of all e-mail attachments also cripple most of the strategies the '.duhust Extension' Ransomware's threat actors might use to install this Trojan.
Malware experts can't confirm there being a freeware decryption product for the '.duhust Extension' Ransomware, but victims may wish to try using one of several Globe Ransomware decryptors before resorting to a dubious equivalent. Under most circumstances, a daily-updated backup can render your data close to invulnerable to the '.duhust Extension' Ransomware's ransom attempts. For removing the '.duhust Extension' Ransomware and other, recently-detected threats, always be careful to update your security software's database and scan your PC with the help of features like Safe Mode.
Since the Globe Ransomware keeps turning and threat authors continue churning out updates like the '.duhust Extension' Ransomware, one or two more extra steps in preserving your files can only be a good thing.
