What is NetSupport Manager?

The NetSupport Manager program is categorized as a Remote Access Tool (RAT). Like most programs of this type, it allow users to access computers, workstations, and servers locally and remotely. This is legitimate software that can be used by anyone, however, RATs are often misused by cyber criminals for malicious purposes, usually to steal various information.

NetSupport Manager recognized by virustotal as a threat

Typically, cyber criminals use various ways to trick people into downloading remote access tools so that they can steal information/personal data and use it to generate revenue. NetSupport Manager is capable of monitoring systems and viewing all connected workstations in real time simultaneously. In summary, it can be used to monitor computing activity and, additionally, to watch, share, and control the screen, mouse, keyboard of any connected computer. It can also record the screen and capture screenshots. NetSupport Manager can be used to access system information such as Operating System, computer type, name of the country in which it is used, installed hardware and software, and many other details. Furthermore, this RAT can be used to transfer data/files between connected computers/workstations. Therefore, users can move files from one computer to another. NetSupport Manager users are also offered some other features. As we mentioned above, these tools are often used by cyber criminals with malicious intent. If installed on a computer without users' knowledge, it can be used to steal personal information. By controlling a computer and transfering files, cyber criminals might download and install malicious programs such as ransomware, high-risk Trojans, and other infections. Having programs of this type installed might cause data/financial loss and other problems. Some of the installed programs might be capable of stealing logins and passwords of personal accounts (such as banking). Therefore, being tricked into installing RAT software can lead to serious problems relating to finances, privacy, and so on. If you believe that NetSupport Manager, or another tool of this type, was installed without your knowledge, remove it immediately.

There are a number of RATs available, and often they are legitimate tools. Some examples of other RATs are Orcus, Agent Tesla, Imminent Monitor, and CrimsonRAT. Note that cyber criminals often use these tools for malicious purposes (to steal information, cause computer infections, and so on).

How did NetSupport Manager infiltrate my computer?

Cyber criminals trick people into downloading and installing this tool using fake Google Chrome, Mozilla Firefox, Flash Player (and other) updaters. These programs are disguised as legitimate update tools, however, rather than downloading and installing updates, they download and install unwanted software, in this case the NetSupport Manager. They also proliferate this RAT through the BGTrade application (its installer). In this way, they trick people into installing NetSupport Manager with the BGTrade app. Note, however, that cyber criminals often proliferate malicious programs through emails - they use malicious attachments disguised as harmless files. Once opened, these attachments (MS Office documents, JavaScript files, executables, archives, and so on) download and install unwanted software. Additionally, they use dubious software download sources. Some examples of dubious download channels are unofficial websites, Peer-to-Peer networks, third party downloaders and other similar sources. By downloading files using these tools, people often cause download and installation of unwanted software (including computer infections). Software cracking tools are used to bypass paid activation (illegally), however, they often download and install malicious programs.

How to avoid installation of malware?

Update software using implemented, official tools that are provided by software developers only. Download software from official websites and using direct links. Do not use the other channels mentioned above. Do not open attachments (or web links) that are presented in irrelevant emails or that are received from unknown, suspicious email addresses. Avoid using software cracking tools, since this is a cyber crime and often causes computer infections. Have reputable anti-virus or anti-spyware software installed and enabled - this can detect harmful files before they do any damage. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

Update September 4th, 2019 - Cyber criminals have recently developed a malicious toolkit called Domen. This toolkit allows threat actors to hijack legitimate websites (at the time of research, most of hijacked websites were based on WordPress CMS) and inject them with a script that displays various fake update notifications. The level of Domen's sophistication is rather high. It is designed to target both desktop and mobile users. Additionally, the fake update messages can be displayed in 30 different languages. Now the list of fake update notifications includes browser updates (e.g., "You Are Using An Older Version Of Chrome"), Adobe Flash Player update (similar to this one), and an error claiming that website's content cannot be displayed due to a missing font and encouraging to update/download a font pack (e.g., "The PT Sans Font Wasnt Found"). The displayed update notifications completely overlay visited websites' content and encourage users to download the update immediately. However, the downloaded file is actually a malicious script which runs a number of shell commands that eventually download and install various malware. At the time of research Domen was used to spread NetSupport Manager RAT. However, the situation may eventually change, especially when the same toolkit can be used by multiple cyber criminals.

How to remove malware manually?

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Malwarebytes for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
