Kurulum Sorunları Çözme

volatility3 pluginleri bulunamıyor

Windows symbol'ları yükle:

pip install volatility3
# ~/.volatility3/ dizinine symbol'lar indir
volatility3 -f memory.dmp windows.registry.printkey

foremost başarısız

Config file gerekli:

foremost -T
# /etc/foremost.conf kontrol et
sudo apt-get install --reinstall foremost

sleuthkit bağımlılıkları

TSK library kurulum:

sudo apt-get install -y libtsk-dev
pip install pytsk3

stegoseek .deb kurulum

GitHub release'ten indir:

wget https://github.com/RickdeJager/stegoseek/releases/download/v0.6/stegoseek_0.6-1.deb
sudo apt-get install -y ./stegoseek_0.6-1.deb

Hızlı Test Scripti

python3 << 'EOF'
import shutil

forensics_tools = [
    'binwalk', 'foremost', 'testdisk', 'fls', 'exiftool',
    'steghide', 'sox', 'ffmpeg'
]

print("=== Forensics Tools Check ===")
missing = []
for tool in forensics_tools:
    if shutil.which(tool):
        print(f"✓ {tool}")
    else:
        print(f"✗ {tool}")
        missing.append(tool)

try:
    import volatility3, exiftool
    print("✓ volatility3, exiftool (Python)")
except ImportError as e:
    print(f"✗ {e}")

if missing:
    print(f"\nEksik: {', '.join(missing)}")
    print("Çözüm: fetih download-tools forensics")
else:
    print("\n✓ Tüm forensics araçları kurulu!")
EOF

Notlar

• volatility3 → memory analysis zorunlu
• binwalk + foremost → file carving temel
• steghide + zsteg + stegoveritas → stegano üçlüsü
• exiftool → metadata extraction her zaman gerekli
• GUI araçları (audacity, sonic-visualiser) → manual analysis
• Audio tools (sox, ffmpeg) → format dönüşüm

Skill okudoğunda başında hangi araçlar gerekli gösterilecek!
