Gear: Full Source Code + Active Remote Exploit
Targets: Windows 11 24H2 (Build 26100.8655 and below) & Core Drivers

PROLOGUE
What's up, bros. Today we are dropping the entire arsenal right here. No more smokescreen screenshots to chase clout, no more ambiguous sale threads, and we are officially skipping those time-wasting escrow extortion games on these dark web boards.
Attached below is the full, clean source code of our Orcahunter Framework v1.0 (1,300+ lines of code) alongside a functional, pre-auth remote packet script targeting the Windows 11 24H2 network stack (tcpip.sys!0x6DB16).
1. TALENT ACQUISITION & INFRASTRUCTURE ENTRY
Due to a change of plans, our crew needs to quickly recruit one more guy who specializes in low-level coding to wrap up our framework modules. If you are a free agent, got the actual skills, and are ready to mess with deep kernel boundaries, hit us up. Script kiddies (skids) please next; don't waste our time.
  • Technical Recruitment Contact: DM directly via Session to test your skills and discuss the onboarding terms.
  • Session ID for Calypso122: 0524a02814c653c6d667feecbfb6ff77144321ccc3ffd1f6cd8b579c7e95ca477d
  • Session ID for the Trading Desk (Buy/Sell): 050478ecf2a2b5807c452969843cc719ef1e815e4c52cd9aa3ab10bb53849c072d
By the way, let's make things clear about purchasing our other custom solutions: We strictly operate through trusted, high-profile crypto-secured escrow setups. No direct deals with unverified third parties, no exceptions. We coded this entire framework from absolute zero, so we know exactly what it can pull off. We dictate the terms, and we trust nobody else.

2. CORE ARCHITECTURE: ORCAHUNTER v1.0 PIPELINE
This toolkit handles automated reverse-engineering, dynamic emulation, and constraint-solving via Python to dig up Kernel Zero-days straight out of raw Windows .sys binaries.
Inside the leak zip:
  • load_pe (PE Parser): Parses raw binary layout, maps the IAT, and hunts down function boundaries using the Windows Exception Directory.
  • InterprocTaint (Data-flow Engine): Tracks data taint across recursive function calls up to 3 levels deep. Propagates taint labels via MOV/LEA and drops them instantly on clear operations like XOR.
  • GarbageFilter (Heuristic Core): Blocks 90% of false positives. This module is extremely smart—it automatically scans for AND bitmask instructions (masked-safe) preceding memory stores to verify if Windows already enforces proper bounds checks.
  • DynVerify Sandbox (Emulation Layer): A mini CPU sandbox powered by Unicorn Engine. It maps out a virtual RAM workspace and injects tracking hooks around buffers to trap live UAF, Double Free, and Double Fetch (TOCTOU) states inside network routines.
  • ExploitScore (Scoring Node): A heuristic grading script. The moment it detects a pool memory leak gap or an index out-of-bounds write boundary, it forces a high-priority urgent tag.



3. TCPIP.SYS 0x6DB16 — PRE-AUTH REMOTE OOB WRITE PoC
An active remote exploit script that uses the Scapy library to cook and fire raw customized network packets. It targets a missing bounds check in function 0x6DB16 (a cold fragment of the logical routine at 0x6D820) inside the WFP ALE classification stack of tcpip.sys.
Technical Reality of the Flaw:
  • The Logic Bug: The kernel routine performs 13 unindexed pointer stores of the form mov dword ptr [rdx + rax*8], esi but contains absolutely zero conditional verification or safety comparison instructions (No Bounds Check) across the execution path.
  • Remote Vector (Pre-Auth): No accounts needed, no user interaction required. Firing a single raw packet (TCP SYN, UDP, or ICMP) triggers the bug. Because the flaw sits inside the low-level WFP ALE metadata classification layer, the Windows network driver is forced to parse it immediately upon arrival, meaning the local Windows software firewall cannot block this attack.
  • Upgrading to RCE via the 72 KB Window: In a production Windows 11 24H2 environment, the destination buffer rdx is a fixed, small internal structure allocated at roughly 72 KB. Lazy static analysis suggests that an unindexed 16-bit packet index jump of up to 1 MB (0xFFFFF0 bytes) will hit unmapped pages and instantly drop the system into a blue screen (Bugcheck 0x50/0x8E - DoS). However, if an operator actually has solid low-level skills and knows how to constrain the incoming packet fields so that the resulting write offset falls precisely between 72 KB and 200 KB, the pointer won't crash the hypervisor. Instead, it will corrupt active network buffers sitting right next to it on the same memory page (Adjacent WFP Buffers). Manipulating this tight corruption window allows you to overwrite internal function pointers, upgrading a remote blue screen crash (DoS) into a full Remote Code Execution (RCE) primitive to hijack the kernel.



4. ELITE PROGRAMMING PROOF OF WORK: NO SKIDS ALLOWED
We intentionally did not weaponize this codebase for script kiddies or automated exploit consumers looking for point-and-click tools. The tcpip_0x6DB16_poc.py script is dropped strictly as a structural skeleton:
  • The Expertise Barrier: The source code only provides the raw packet delivery setup to test mathematical boundaries. The heavy lifting required to maintain stability, calculate remote pool feng shui layouts, and defeat modern mitigation layers like HVCI or Kernel CFG must be written manually using your own brain and skills.
  • Absolute Proof of Work: Building an automated binary analysis pipeline using Capstone, Unicorn, and Z3 from the ground up, and successfully using it to catch a massive 1 MB missing bounds check within the most hardened network stack on the planet, is the ultimate proof of low-level software engineering prowess. This leak stands as an undeniable portfolio asset confirming expert-level vulnerability research capabilities, completely shredding internet rumors that this crew only knows how to run social engineering stunts.



5. DOWNLOAD LINKS & TELEMETRY
The leaked package contains the raw Python code for Orcahunter.py, the internal audit logs for 8 drivers (including afd.sys, http.sys, srv2.sys), and the remote Scapy attack script. Note: If the target endpoint is unpatched (Windows 11 24H2 build 26100.8655 or lower), it will instantly trigger a Bugcheck 0x50/0x8E blue screen or undergo kernel memory page corruption, depending on whether the operator knows how to adjust the index boundaries with precision.

A little gift from Calypso122 to MSnightmare and the rest of the world. Happy exploiting, bro! Big Grin

Only those who actually have the skills can weaponize this into a full RCE, lol Big Grin I already handed you the exact address on a silver platter, so if you still can't write the code, you're just pathetic Big Grin
lol
