This repository provides a proof-of-concept (PoC) exploit for CVE-2021-26258, a vulnerability in Intel Killer software's update mechanism. The exploit consists of two main components: a Python script (WebSrv.py) that acts as a simple HTTP server to serve a malicious .stg configuration file, and a C++ tool (rnstg-tool) for packing and unpacking Killer storage files (.stg). The README details the attack scenario: by redirecting the domain www.killernetworking.com (e.g., via hosts file modification), the attacker can serve a crafted .stg file to the Killer software when it checks for updates. The malicious .stg file can disable network access for specific applications (such as Discord.exe) and enable the RemoteRegistry service, potentially facilitating further attacks. The repository includes build files for the C++ tool and instructions for setting up the attack environment. The exploit demonstrates a network-based attack vector and targets Windows systems running Intel Killer software.
