EnigmaSoft Threat Scorecard
EnigmaSoft Threat Scorecards are assessment reports for different malware threats which have been collected and analyzed by our research team. EnigmaSoft Threat Scorecards evaluate and rank threats using several metrics including real-world and potential risk factors, trends, frequency, prevalence, and persistence. EnigmaSoft Threat Scorecards are updated regularly based on our research data and metrics and are useful for a wide range of computer users, from end users seeking solutions to remove malware from their systems to security experts analyzing threats.
EnigmaSoft Threat Scorecards display a variety of useful information, including:
Ranking: The ranking of a particular threat in EnigmaSoft’s Threat Database.
Severity Level: The determined severity level of an object, represented numerically, based on our risk modeling process and research, as explained in our Threat Assessment Criteria.
Infected Computers: The number of confirmed and suspected cases of a particular threat detected on infected computers as reported by SpyHunter.

PWS-Duqu, also detected as Duqu, PWS-Duqu.dr and PWS-Duqu!rootkit, is a backdoor Trojan and successor of the most complicated and dangerous attack of this decade named Stuxnet. Basically, Duqu is based on Stuxnet, and some of its parts are almost identical to Stuxnet, but have a totally different aim. In contrary to Stuxnet, PWS-Duqu does not contain PLC functionality like Stuxnet. Instead, the code which is spread via exploitation, installs drivers and encrypted DLLs that operate very similar to the original Stuxnet code. The driver's code, encryption keys and methods used for the PWS-Duqu's injection attack are very similar to Stuxnet. The aim of Duqu is to collect intelligence data and assets from entities, such as industrial control system manufacturers, in order to more easily execute a future attack against another third-party. Attackers are looking for information such as design documents that could help them start a future attack on an industrial control facility. Duqu does not involve any code associated with industrial control systems and does not replicate itself. Duqu is used to install another infostealer that could record keystrokes and steal other targeted computer system's information. Duqu uses HTTP and HTTPS to communicate with a command-and-control (C&C) server that in the course of writing is still functional.
PWS-Duqu, also known as Duqu, has an interesting way of stealing data. Duqu utilizes a JPG image file to transmit stolen information from an infected system. Duqu is known to send an http request to a server identified as 206.183.111.97 (site URL: canoyraqomez.rapidns.com) and returns a blank JPG image. The image file, if properly access, will return a photo of a NASA galaxy image. Contained in the image is the stolen data that can easily be transmitted to a remote location by Duqu. It is highly suggestive that Duqu be removed before this is able to happen.
