What is Belonard?

Belonard is a trojan-type virus that targets Counter Strike 1.6 players. This malware infiltrates computers by exploiting remote code execution (RCE) vulnerabilities in the game client. After successful infiltration, Belonard modifies the game client to promote various servers, delivers ads, and so on.

Belonard malware

One of the main purposes of Belonard is to promote various Counter Strike 1.6 servers. Any server owner can pay Belonard developers a fee and the malware will then start promoting the server. Belonard achieves this by modifying the infected client so that the server list prioritizes servers promoted via Belonard. Note also that the infected machine is used to spread Belonard even further. Cyber criminals proliferate Belonard using proxy servers to exploit the aforementioned RCE vulnerabilities. Proxies redirect users with a high response time (ping) to game servers in different geo-locations or hosts. This is to "smooth" the connection and gain a faster response time, however, cyber criminals also use these proxies to redirect users to game servers that execute malicious code and inject Belonard into the system. This malware runs a proxy server on each infected machine, which also redirects to the same servers designed to execute malicious code. Another distribution method changes the player's nickname. Belonard is designed to assign the player's nickname to a URL, which is a download link of an already infected Counter Strike 1.6 client. In summary, Belonard itself is not a particularly high-risk trojan (at least not yet). As mentioned above, its main purpose is to help developers generate revenue by promoting Counter Strike 1.6 game servers. Note that the entire Belonard network has been shut down, however, there is the possibility that criminals will start another infection campaign and continue to promote servers. At this time, Belonard does not pose a significant threat (its functionality does not include other malware promotion, information stealing, or other similar malicious actions). Therefore, unless cyber criminals modify this malware in future, victims will notice just two effects: system performance will decrease (due to running a proxy server) and the list of game servers will be modified. In any case, we strongly recommend that you eliminate this malware by scanning the system with a reputable anti-virus/anti-spyware suite and removing all detected threats. You should also reinstall the game client, however, be sure to download it from trustworthy/official sources only.

Belonard is a rather an uncommon trojan and, thus, shares few similarities with other infections of this type. In most cases, trojan-type infections record sensitive data (logins/passwords, credit card information, keystrokes, etc.) and inject additional malware into the system. They pose a significant threat and their presence might lead to serious privacy issues (financial loss, identity theft, etc.), permanent data loss, and various other problems. Some examples of trojans that pose such threats are AZORult, Adwind, TrickBot, FormBook, Hancitor, and Emotet.

How did Belonard infiltrate my computer?

As mentioned above, Belonard is mainly distributed using proxy servers. Therefore, unlike in most computer infections, Belonard infiltration is not generally caused by users. It commonly infiltrates when users connect to a server and are redirected to malicious websites. As mentioned, Belonard sets the victim's in-game nickname to an infected game client download link. In this way, developers also proliferate already-infected game clients and, thus, Belonard infection might occur when users downloaded the Counter Strike 1.6 game client from a dubious source. In most cases, the main reasons for computer infections are poor knowledge of these threats and careless behavior.

How to avoid installation of malware?

Trojan-type infections are usually proliferated using email spam campaigns (malicious attachments), fake software updaters, cracking tools, third party software download sources (peer-to-peer [P2P] networks, freeware download websites, free file hosting sites, etc.), and other trojans (chain infections). Therefore, to prevent computer infections, be very cautious when browsing the internet and downloading, installing, and updating software. Carefully study each email attachment received. If the file/link is irrelevant or the sender seems suspicious, do not open anything. Download applications from official sources only (via direct download links) and avoid using third party downloaders/installers, since they often include rogue apps. Keep installed applications (and operating systems) up-to-date, however, this should be achieved only through implemented functions or tools provided by the official developer. Never use software cracking tools, since software piracy is considered a cyber crime and the risk of infection is extremely high. Lastly, have a legitimate anti-virus/anti-spyware suite installed and running. These tools protect the system by detecting and eliminating malware before the system is damaged. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

To remove this malware we recommend using Combo Cleaner Antivirus 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 Combo Cleaner Antivirus for Windows.
