An alleged threat actor has listed a Windows Zero-Day Remote Code Execution (RCE) exploit for sale, claiming it targets fully updated Windows 10, Windows 11, and Windows Server 2022 systems.
The posting reported by ThreatMon advertises weaponized exploit code purportedly capable of granting SYSTEM-level privileges with no prior authentication or user interaction, bypassing intrinsic Windows security controls such as Address Space Layout Randomization (ASLR), Data Execution Prevention (DEP), and Control Flow Guard (CFG).
The seller emphasizes the exploit’s technical capabilities, offering kernel-level code execution and privilege escalation directly to SYSTEM—a critical concern for both enterprise and individual systems.
Key Takeaways
1. $125k Windows zero-day RCE exploit targets patched Win10/11/Server2022 with SYSTEM privileges.
2. Bypasses ASLR/DEP/CFG, evades AV/EDR detection.
3. A network-based attack requires no user interaction.
The advertisement claims that the exploit is undetected by leading antivirus and endpoint detection and response (EDR) solutions, boasting a stealthy profile with “no signatures detected.”
With a purported success rate exceeding 95%, the exploit’s reliability makes it exceptionally attractive to advanced persistent threat (APT) groups and ransomware operators.
Technical Details of Zero-Day RCE Exploit
The exploit is designed for remote code execution (RCE) via a network-based attack vector, eliminating the need for any user interaction.
This tactic aligns with the most dangerous categories of vulnerabilities, especially those facilitating “unauthenticated remote attack surface” exploitation.
The exploit’s capacity to elevate privileges—typically from a standard user to SYSTEM, the highest Windows permission level. Additionally, direct interaction and manipulation of the Windows kernel bypasses typical user-mode restrictions.
Auction details reveal an asking price of USD 125,000, with payment preferred via cryptocurrency (BTC/XMR), reflecting the high market demand for robust, undetectable exploit code.
The sale conditions emphasize exclusivity, prohibiting resale unless explicitly negotiated, which is typical for premium exploits.
Organizations facing heightened threat landscapes should reinforce monitoring of anomalous kernel-level activity, enforce timely patch management, and deploy advanced threat intelligence tools capable of detecting zero-day exploitation attempts.
The incident underscores the persistent risks associated with unreported vulnerabilities and the continued evolution of cybercrime marketplaces.
It is recommended to stay informed of emerging threat intelligence feeds, apply available mitigations, and report suspicious activity associated with zero-day vulnerabilities to relevant authorities and vendors.
