This malware is designed to extract and steal data, e.g. from the infected systems, applications installed on it, services accessed through it, etc. However, stealers can have other abilities as well. They can having spying functionalities (e.g. taking screenshots, recording audio/video from integrated/connected microphones and cameras, etc.), downloading/installing additional malware (e.g. trojans, ransomware, etc.), and so on. The only goal of malicious software is to generate revenue for the cyber criminals using them.

How did FickerStealer infiltrate my computer?

Malware is distributed via spam campaigns, illegal activation ("cracking") tools, fake updaters and untrustworthy download channels. The term "spam campaign" is used to describe a large-scale operation, during which thousands of deceptive/scam emails are sent. These letters are usually presented as "official", "important", "urgent", "priority" and similar. This mail contains download links of infectious files and/or the files are simply attached to emails. Virulent files can be in different formats, e.g. archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), PDF and Microsoft Office documents, JavaScript, and so forth. When these files are executed, run or otherwise opened - the infection process is triggered. Illegal activation tools ("cracks") can download/install malware, instead of activating licensed product. Fake updaters cause infections by exploiting flaws of outdated products and/or by installing malicious programs, rather than the promised updates. Untrustworthy download sources, e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - can offer malware for downloading, disguised as and/or bundled with ordinary content.

How to avoid installation of malware?

Suspicious and/or irrelevant emails must not be opened, especially any links or attachments present in them - as that can result in a high-risk system infection. It is recommended to only use official and verified download channels. Additionally, all products must be activated and updated using tools/functions provided by legitimate developers. Illegal activation ("cracking") tools and third party updaters are advised against use, as they often proliferate malware. To protect device integrity and user safety, it is crucial to have a dependable anti-virus/anti-spyware suite installed and kept updated. This software has to be used to perform regular system scans and to remove detected threats and issues. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

Update April 21, 2021 - FickerStealer has been observed being proliferated via malicious websites. They were disguised as the Spotify, Microsoft Store, and file format conversion sites. These webpages were promoted through malvertising (malicious software advertising) campaigns. The ads were thematically linked with the guise of the malignant websites, e.g., promoted a fake chess game application - "xChess 3'", etc. When entered, the pages automatically downloaded an archived file (e.g., "xChess_v.709.zip"; filename may vary) via the Amazon AWS service. Once the executable contained therein was run, it triggered the infection chain (installation) of FickerStealer malware.

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.
