Ducktail PHP stealer in general
Ducktail is used to steal information from Facebook accounts, browsers, and cryptocurrency wallets. Additionally, it collects some information about the infected computers (system data). As we mentioned in the introduction, Ducktail is now targeting regular users too.
Threat actors aim to steal whatever valuable information victims have stored in their Facebook accounts, cryptocurrency wallets, and browsers to perform malicious activities. It is known that Ducktail runs in the Task Manager as "CLI" (the name of the process may vary).
How did Ducktail PHP stealer infiltrate my computer?
It is known that Ducktail malware is distributed using malicious executable files. Threat actors put these executables in archive files (mostly in ZIP files). These files are distributed via file sharing platforms/file hosting websites. They are disguised as installers for pirated/cracked software (e.g., cracked MS Office applications), games, subtitle files, etc.
The infection chain starts with the execution of a malicious executable file placed in a ZIP file.
How to avoid installation of malware?
Never download any cracked/pirated software. Download software from official websites and platforms. Do not use P2P networks, shady pages, third-party downloaders, free file hosting (or sharing) sites, etc., as sources for downloading files and programs.
Do not trust ads on questionable websites. Always check downloaders and installers for optional downloads and installations and deselect them. Examine emails before opening links or attachments presented in them (irrelevant emails sent from unknown/suspicious addresses can contain malicious files or links).
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.

In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check 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".
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. To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
