Distribution of NxRansomware Virus

The NxRansomware Virus is a new virus which has been sighted in a limited attack campaign. At the moment the security researchers cannot determine the primary infection strategy. We presume that the most widely used tactics are going to be employed.

Among them are the email messages created in an automated way and sent to large lists of potential victims. The NxRansomware Virus can be directly attached to the messages. This is one of the easiest way for the criminals to attempt the infection. However a lot of email hosting providers usually capture the signatures of the virus and as such discard such messages or label them as dangerous or spam. Other infection methods related to this one is the option of inserting hyperlinks in the body content of the messages. The links are usually labeled as leading to a familiar website or a file of user interest. Redirects can redirect to hacker-controlled sites, infected payloads or other instances that can lead to an NxRansomware Virus infection.

The computer criminals behind the malware can create malicious sites or download portals which distribute malware of different kinds, including the NxRansomware Virus. A popular option is the use of infected documents which may be of different types ‒ spreadsheets, rich text documents, presentations and databases. They are modified to initiate the virus once the built-in scripts are run. Usually when the files are opened a notification will ask the users to run the macros (scripts). If this is done the infection follows.

The hacker-controlled sites are specialist portals that have been created either manually or automatically by the criminals behind the NxRansomware Virus. They can either directly distribute the threat by initiating various scripts or automated operations or link to such instances. Redirects are usually caused by email interaction, ad networks or other browsing activity. However one of the main sources is the availability of browser hijackers. They are malicious addons made for the most popular web browsers ‒ Mozilla Firefox, Google Chrome, Internet Explorer, Opera, Microsoft Edge and Safari. Once installed they not only infect the users with the malware, but also redirect the victims to a hacker-controlled site. Depending on the configuration the browser hijackers can also steal sensitive information such as any stored passwords, account credentials, history, bookmarks, form data and settings.

Impact of NxRansomware Virus

Security analysis detected a new ongoing attack using an open-source malware called the NxRansomware virus. Its initial versions were detected back in March 2016 and it is believed that the current attack wave carries an updated strain of it. The development of the threat started as a project hosted on GitHub by a developer called Guilherme Bacellar Moralez under the nickname of guibacellar. Its original purpose was to create a tool for education use. The original code of the NxRansomware Virus contains two parts — the virus itself and the C&C station code.

The code is written using the .NET framework that makes it compatible with all contemporary versions of the Microsoft Windows operating system family. Among the characteristics defined by the developer is the ability of the infection engine to covertly install itself even in the presence of security software. It is able to disable and delete some anti-virus products, firewalls and any other signatures introduced to the code by the operator. If the virus cannot remove the threat then it will delete itself to prevent discovery.

The malware operators are given a modular framework that they can utilize in their attacks. The original developer describes it as a “state of the art” in the release notes. A secure connection is created and maintained between the infected host and the C&C servers. A database of the infected hosts is actively managed that uses in-memory storage and advanced cryptography.

Effectively this gives the NxRansomware virus operators the ability to extend the modular framework with other modules of their own. An advanced attack can utilize a Trojan component. It facilitates spying on the infected hosts by allowing the hackers to view the display of the victims. Some versions allow the recording of keystrokes and the mouse movement to a separate file.

Other dangerous actions include an information gathering module which has the ability to hijacks sensitive information about the victims and their computers. The list includes the available hardware components, installed software and user data. For example the NxRansomware Virus can be instructed to extract data from popular apps such as the web browsers. In this case the stored cookies, bookmarks, history, passwords and account credentials can be retrieved.

Once the post-infection process has complete the ransomware component is launched. It seeks to encrypt target user data based on a built-in list of target file type extensions. Earlier versions have been found to act against the following data:

.AVI, .C, .CLASS, .CONFIG, .CPP, .CS, .CSC, .DBX, .DOC, .DOCX, .EML, .GIF, .GZ, .H, .JAVA,
.JPG, .JS, .JSON, .JSP, .MBX, .MP3, .MP4, .MPEG, .MSG, .NEF, .PDF, .PHP, .PNG, .PPT, .PPTX,
.PST, .PY, .R, .RAR, .TAR, .TXT, .VB, .VBS, .WAB, .XAML, .XLS, .XLSX, .ZIP

Once this process is complete a lockscreen instance is instituted that prohibits ordinary computer interaction until the threat has been completely removed. It is created using an application frame that is superimposed over all open windows bearing the title “I’ll Make you Cry 😀 :D”. The contained message reads the following:

What has happened To your Computer?

Your computer has been encrypted
Its better to pay ransom

Or we are going to make you feel sorry

Then noboy will help you out

Can I Recover my files back?

Yes you can. Just pay us the bitcoins and we will send you decryption code
