What is DarkStealer?
DarkStealer is a malicious software designed to function as a file grabber, data stealer, remote administration tool. This software is for sale on a hacker forum where cyber criminals can purchase a monthly subscription for it. DarkStealer is quite a powerful malware which can be used for a variety of malicious purposes. Users who have this malware installed on the operating system should eliminate it as soon as possible.
One of the features available in DarkStealer is the remote administration/access tool. It means that cyber cyber criminals can access and control infected computers, and perform certain actions (e.g., download and execute malicious files, log keystrokes, access sensitive documents, files, etc.). Also, DarkStealer can be used as a tool to steal passwords, cookies, maps, various forms, browsing history and other data saved on browsers. The biggest issue with it is that by having an access to such data cyber criminals could use it to steal various accounts (including email, social media, banking-related and other accounts). Research shows that DarkStealer has a separate feature targeting email clients only as well. Also, it is capable of stealing data from installed VPN and Discord clients, cryptocurrency wallets, and operating as a file grabber. Moreover, cyber criminals can use DarkStealer as a tool to take screenshots, which means they could have images of any opened documents, accounts, etc. To sum up, users who have this malware installed on the operating system may become victims of identity theft, suffer monetary loss, lose access to personal accounts, have their computers infected with other malware (e.g., Trojan, ransomware), experience serious problems related to online privacy, browsing safety and other issues.

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

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
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.
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.
