What is Buerak?

Buerak is the name of a malicious program which is categorized as a Trojan: it is designed to open 'backdoor' for other malicious software. Simply said, Buerak is designed to cause chain infections/infect computer with various other malware. It may be used to spread a variety of malicious programs that could cause a number of serious problems. Therefore, if there is any reason to think that the operating system is infected with Buerak, then it should be eliminated as soon as possible.

Buerak malware

Buerak could be used to spread (install) ransomware, keyloggers, remote access trojans (RATs), cryptocurrency miners, some banking malware, and so on. Ransomware is a type of software that encrypts victim's files with a strong encryption algorithm. Quite often it is impossible to decrypt files without tools that can be purchased only from cyber criminals who designed ransomware. Keyloggers are programs that cyber criminals attempt to trick people into installing on their computers with a purpose to steal confidential information. These programs record keystrokes (pressed keys), which means they can be used to steal credentials (logins, passwords), credit card details and various other sensitive details that could be misused to generate revenue in various ways. RATs are programs that allow cyber criminal to control victim's computer remotely. They can be used for a variety of purposes. For example, to take screenshots, monitor computing activity, install malicious programs, steal sensitive information, access various files, establish a botnet, and many other things. Cryptocurrency miners are programs that use computer hardware (CPU, GPU) to mine cryptocurrency by solving mathematical problems. Simply said, cyber criminals employ infected machines as tools to generate revenue. It is common that users of computers that are infected with cryptocurrency miners experience unexpected shutdowns, hardware overheat, decrease in computer's performance, receive higher electricity bills. Also, Buerak could be used to install some banking malware or other software of this type that is designed to steal banking-related information, and/or other sensitive details that could be misused to generate revenue in one or another way. In one way or another, victims of Buerak attack may become victims of identity theft, suffer monetary, data loss, experience problems related to privacy, browsing safety, and other serious issues.

Buerak is similar to many other programs of this type, some examples are Buer Loader, Borr and sLoad. In most cases cyber criminals use trojan-type programs to steal sensitive information or infect systems with other programs that are capable of that. In one way or another, victims who have programs of this kind installed on the operating system are exposed at risk of variety of serious problems.

How did Buerak infiltrate my computer?

Research shows that Buer is being distributed through a deceptive website claiming that some security certificate is out of date and encouraging to install its updates. That page is designed to download a malicious executable file which, if executed, installs Buerak. Unofficial, questionable pages should never be used as tools to download any files. The same applies to various Peer-to-Peer networks (like torrent clients, eMule), third party downloaders, freeware download pages, free file hosting sites, and other channels of this kind. Also, third party installers should bot be used too. It is common that cyber criminals use them as tools to host, distribute various malicious files.

How to avoid installation of malware?

Attachments and website links in irrelevant emails that are received from unknown, suspicious addresses should not be opened. It is common that cyber criminals disguise their emails as official, important, and so on. If there is any reason to suspect that an email cannot be trusted, then its contents should be left unopened. Files and programs should be downloaded via direct links and trustworthy, official websites. Other sources, tools that are mentioned in the previous paragraph should not be used for that. Installed software must be updated and activated with tools and/or implemented functions that are provided by official software developers. Third party updaters and activation tools can be (and often are) used to spread malicious programs. Additionally, it is not legal to activate licensed software with 'cracking' (unofficial activation) tools. Operating system should be regularly scanned for threats with a reputable antivirus or anti-spyware suite. If it detects any threats, then they should be removed as soon as possible. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

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 Spyhunter for Windows.
