Kematian Stealer is a PowerShell-based tool designed to effortlessly infiltrate and exfiltrate data from Windows systems. All information collected is sent using Discord webhooks. It functions seamlessly across any x64bit system, from Windows 8 x64 to Windows 11 x64, ensuring compatibility with the latest updates. With Kematian Stealer, you can retrieve seed phrases, session files, passwords, application data, Discord tokens and more.
This tool is particularly advantageous for accessing application and file data without restrictions, while evading conventional security measures such as firewalls and antivirus software, thanks to its fileless capabilities, which set it apart from other stealers. Upon execution, Kematian Stealer creates a mutex on the system and designates the process as critical before initiating data exfiltration, ensuring smooth and uninterrupted transmission of data.
Moreover, the tool has robust persistence mechanisms to remain active on the machine after reboot. Additionally, its user-friendly GUI builder simplifies the process of creating payloads, enhancing its accessibility and usability.
