| 1 | ## Cybersecurity Skills (Invoke First) |
| 2 | |
| 3 | Before starting recon, invoke these skills via the Skill tool to load expert methodology: |
| 4 | - `cybersecurity-skills:scanning-network-with-nmap-advanced` |
| 5 | - `cybersecurity-skills:performing-subdomain-enumeration-with-subfinder` |
| 6 | - `cybersecurity-skills:conducting-external-reconnaissance-with-osint` |
| 7 | |
| 8 | ## Scope Enforcement |
| 9 | **CRITICAL**: Before running ANY network tool, verify the target is in `scope.txt`. |
| 10 | Read scope.txt and confirm the target IP/domain is listed. If not found, STOP and output: |
| 11 | "TARGET [X] is not in scope.txt. Add it before proceeding." |
| 12 | |
| 13 | The PreToolUse hook (scope_check.py) enforces this automatically, but always verify manually first. |
| 14 | |
| 15 | ## Reconnaissance Workflow |
| 16 | |
| 17 | ### Phase 1: Host Discovery & Port Scanning |
| 18 | ```bash |
| 19 | # Full TCP scan (stealth SYN) |
| 20 | nmap -sS -T4 -p- --open -oA evidence/$(date +%Y%m%d)/$TARGET/nmap/tcp_full $TARGET |
| 21 | |
| 22 | # Service + script scan on discovered ports |
| 23 | PORTS=$(grep -oP '\d+/open' evidence/$(date +%Y%m%d)/$TARGET/nmap/tcp_full.gnmap | grep -oP '^\d+' | tr '\n' ',' | sed 's/,$//') |
| 24 | nmap -sV -sC -p $PORTS -oA evidence/$(date +%Y%m%d)/$TARGET/nmap/svc_scan $TARGET |
| 25 | |
| 26 | # UDP top 200 |
| 27 | nmap -sU --top-ports 200 -oA evidence/$(date +%Y%m%d)/$TARGET/nmap/udp_top200 $TARGET |
| 28 | ``` |
| 29 | |
| 30 | ### Phase 2: Vulnerability Scanning |
| 31 | ```bash |
| 32 | # Nuclei CVE + exposure scan |
| 33 | nuclei -u $TARGET -t cves/ -t exposures/ -t misconfiguration/ \ |
| 34 | -severity critical,high,medium \ |
| 35 | -o evidence/$(date +%Y%m%d)/$TARGET/nuclei/nuclei_results.txt \ |
| 36 | -json > evidence/$(date +%Y%m%d)/$TARGET/nuclei/nuclei_json.txt |
| 37 | |
| 38 | # Default credentials check |
| 39 | nuclei -u $TARGET -t default-logins/ -o evidence/$(date +%Y%m%d)/$TARGET/nuclei/default_creds.txt |
| 40 | ``` |
| 41 | |
| 42 | ### Phase 3: Web Enumeration |
| 43 | ```bash |
| 44 | # HTTP probing with tech detection |
| 45 | httpx -u $TARGET -title -tech-detect -status-code -content-length \ |
| 46 | -web-server -follow-redirects \ |
| 47 | -o evidence/$(date +%Y%m%d)/$TARGET/web/httpx.txt |
| 48 | |
| 49 | # Directory and file brute-force |
| 50 | feroxbuster -u http://$TARGET \ |
| 51 | -w /usr/share/seclists/Discovery/Web-Content/raft-medium-words.txt \ |
| 52 | -x php,asp,aspx,jsp,txt,bak,zip,env,config,sql,json,xml \ |
| 53 | --timeout 10 --threads 50 \ |
| 54 | -o evidence/$(date +%Y%m%d)/$TARGET/web/ferox_http.txt |
| 55 | |
| 56 | # HTTPS if applicable |
| 57 | feroxbuster -u https://$TARGET -k \ |
| 58 | -w /usr/share/seclists/Discovery/Web-Content/raft-medium-words.txt \ |
| 59 | -x php,asp,aspx,jsp,txt,bak,zip,env,config \ |
| 60 | --timeout 10 --threads 50 \ |
| 61 | -o evidence/$(date +%Y%m%d)/$TARGET/web/ferox_https.txt |
| 62 | ``` |
| 63 | |
| 64 | ### Phase 4: Subdomain Enumeration (if domain target) |
| 65 | ```bash |
| 66 | # Passive subdomain discovery |
| 67 | subfinder -d $DOMAIN -o evidence/$(date +%Y%m%d)/$TARGET/dns/subfinder.txt |
| 68 | |
| 69 | # Active enumeration with amass |
| 70 | amass enum -passive -d $DOMAIN \ |
| 71 | -o evidence/$(date +%Y%m%d)/$TARGET/dns/amass_passive.txt |
| 72 | |
| 73 | # DNS resolution of discovered subdomains |
| 74 | cat evidence/$(date +%Y%m%d)/$TARGET/dns/subfinder.txt \ |
| 75 | evidence/$(date +%Y%m%d)/$TARGET/dns/amass_passive.txt | sort -u | \ |
| 76 | dnsx -resp -a -cname -mx -ns \ |
| 77 | -o evidence/$(date +%Y%m%d)/$TARGET/dns/resolved.txt |
| 78 | ``` |
| 79 | |
| 80 | ### Phase 5: Certificate Transparency |
| 81 | ```bash |
| 82 | # Certificate transparency logs |
| 83 | curl -s "https://crt.sh/?q=$DOMAIN&output=json" | \ |
| 84 | python3 -c " |
| 85 | import json, sys |
| 86 | data = json.load(sys.stdin) |
| 87 | names = set() |
| 88 | for entry in data: |
| 89 | name = entry.get('name_value', '') |
| 90 | for n in name.split('\n'): |
| 91 | n = n.strip().lstrip('*.') |
| 92 | if n: |
| 93 | names.add(n) |
| 94 | for n in sorted(names): |
| 95 | print(n) |
| 96 | " > evidence/$(date +%Y%m%d)/$TARGET/dns/crt_sh.txt |
| 97 | ``` |
| 98 | |
| 99 | ## Attack Surface Summary |
| 100 | After all phases complete, write `evidence/$(date +%Y%m%d)/$TARGET/recon_summary.md`: |
| 101 | |
| 102 | ```markdown |
| 103 | # Recon Summary — $TARGET — $(date -u +%Y-%m-%dT%H:%M:%SZ) |
