The Mr. Dec virus has been discovered in a small attack campaign. While the initial strains do not feature advanced code it is expected that future versions will be much more dangerous. The affected files are renamed with random extensions, read more about the threat in our removal guide.
Threat Summary
Name
Mr. Dec
Type
Ransomware, Cryptovirus
Short Description
The ransomware encrypts sensitive information on your computer system with the .[random-extension] extensions and demands a ransom to be paid to allegedly recover them.
Symptoms
The ransomware will encrypt your files with a strong encryption algorithm.
Windows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.
Mr. Dec Virus – Distribution Ways
The Mr. Dec virus has been identified in a very small attack campaign that does not give out the primary distribution tactics. As such we expect that the most common methods are going to be used.
Future Mr. Dec virus campaigns can utilize SPAM email messages that rely on social engineering tactics. They use text and graphics that have been hijacked from legitimate sites, products and services in order to blackmail the recipients into infecting themselves. This is done by either attaching the file directly to the messages or hyperlinking the relevant in the body contents. In connection with this payloads can be spread using them. Two of the most popular examples include the following:
Software Installers — The criminals behind the threat can embed the relevant virus code in application installers. Usually the most popular ones are used: creativity suites, system utilities, productivity apps, office programs and even computer games.
Infected Documents — Using similar mechanisms the hackers may embed scripts that lead to the Mr. Dec infection. Practically all document types can be affected: text files, presentations, databases or spreadsheets. Once they are opened by the victims a notification message will appear asking the users to enable the built-in macros. If they do this then the infection will begin.
Another possibility would be the use of browser hijackers. They represent malicious web browser plugins that are made for the most popular applications: Mozilla Firefox, Google Chrome, Internet Explorer, Opera, Safari and Microsoft Edge. Their main goal is to redirect the victims to a hacker-controlled site by changing the browser’s default settings — home page, search engine and new tabs page. Afterwards the Mr. Dec virus infection follows. These strains are usually found on the relevant web browser plugin repositories. The hackers typically make use of fake developer credentials and user reviews along with an elaborate description with the promise of adding new useful features or otherwise changing the browsing experience.
Other delivery methods include the use of web scripts that come in various forms and can even affect legitiamte and well-known sites through compromised ad and affiliate networks. The most common forms are all manners of pop-ups, redirects, in-body hyperlinks and other scripts.
Mr. Dec Virus – In-Depth Analysis
The Mr. Dec virus appears to be a newly created ransomare that does not originate from any of the well-known malware families. This means that either the threat has been created by by its operators or it has been bought from the underground markets. Whatever its origins it appears that the captured samples are test versions or the initial builds. This means that many of the essential virus features are not yet integrated. If the first attacks are successful then future versions will likely be developed.
The initial infection can begin with an information gathering engine. It is programmed to harvest various types of strings in advance. The harvested campaign metrics can be used to optimize the attacks by registering the installed hardware components and certain operating system strings. The same engine can be used to harvest personally-identifiable about the victims that can expose their identity. Example strings include their name, address, telephone number, geographic location, interests, passwords and account credentials.
The information can be processed by the stealth protection module which protects the malicious executable from any applications or services that can interfere with its correct execution. Examples include anti-virus products, sandbox environments and virtual machine hosts.
The Mr. Dec virus can be programmed into modifying the Windows Registry entries related either to the user-installed applications or the operating system itself. When the virus modifies application entries certain services or functions can be rendered non-working. Windows-related entries can lead to overall performance issues.
This is also used to set the Mr. Dec virus as a persistent threat. This means that the virus will start automatically once the computer boots and access to certain menu options will be blocked. This includes the recovery boot menu. In such cases the only way to recover the infected machines is by using a quality anti-spyware solution, read our removal instructions for further information. To make recovery more difficult the threat can also be configured to delete the Shadow Volume Copies of the affected data. This means that data recovery is possible with the use of a professional application.
Advanced versions of the Mr. Dec virus can also be used with a malware network connection to the hacker-controlled servers. It is used in order to harvest the acquired personal data, as well as spy upon the victims in real time. Such methods are widely used in a Trojan-like manner that allow the controllers to overtake control of the machines. They are also among that main methods that are used to deploy additional threats.
We remind our readers that many of the updated ransomware threats at some point add browser hijacker like code that can interact with web browsers and other user-installed applications. This includes the likes of tracking cookies, plugins and other malicious software without the victim’s consent and knowledge.
Mr. Dec Virus – Encryption Process
The associated ransomware engine with the Mr. Dec virus is fully functional even with the test versions that were captured by the analysts. Like other popular ransomware threats it uses a strong cipher (AES) that is used to encrypt sensitive user data. It uses a built-in list that affects the following data:
Archives
Backups
Documents
Databases
Images
Videos
Music
Instead of using a generic rename template the Mr. Dec virus processes the affected data with a random extension which follows the following formula: .[ID][ID]. This means that a randomly-generated string will be made for each victim, it is very likely that it is calculated using the harvested hardware components information.
A ransomware note is crafted in a file called Decoding help.hta that contains the following message:
You are unlucky! The terrible virus has captured your files! For decoding please contact by email [email protected] or [email protected] Your ID ***** ID 1. In the subject line, write your ID. 2. Attach 1-2 infected files that do not contain important information (less than 2 mb) 3. Attach the file with the location c:\Windows\DECODE KEY.KEY are required to generate the decoder and restore the test file. Hurry up! Time is limited! Attention!!! At the end of this time, the private key for generating the decoder will be destroyed. Files will not be restored! 0·1·19·28

Try to Restore Files Encrypted by Mr. Dec
Ransomware infections and Mr. Dec aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
