Sublist3r
Passive subdomain enumeration via OSINT — search engines, DNSDumpster, VirusTotal.
Quick Start
pip install sublist3r
# Basic subdomain enum
sublist3r -d target.com
# With brute-force
sublist3r -d target.com -b -w wordlist.txt
# Save output
sublist3r -d target.com -o subdomains.txt
# Verbose (show sources)
sublist3r -d target.com -v
Core Flags
| Flag | Purpose |
|------|---------|
| -d DOMAIN | Target domain |
| -b | Enable brute-force |
| -w FILE | Brute-force wordlist |
| -p PORTS | Check ports on found hosts |
| -v | Verbose (show each source) |
| -t N | Threads (default: 10) |
| -o FILE | Output file |
| -e ENGINES | Comma-separated engines |
Sources Used
Google · Bing · Yahoo · Baidu · Ask · Netcraft · DNSDumpster · VirusTotal · ThreatCrowd · SSL certs · PassiveDNS
Common Workflows
Passive only (stealthy):
sublist3r -d target.com -o passive_subs.txt
Active brute + passive combined:
sublist3r -d target.com -b -w /usr/share/seclists/Discovery/DNS/subdomains-top1million-5000.txt -o all_subs.txt
Pipe to resolver:
sublist3r -d target.com -o subs.txt
cat subs.txt | dnsx -silent -a -resp > live.txt

VerifiedTrustedCommunity
Offensive methodology for ICS/OT/SCADA environments in authorized industrial penetration testing and red team operations. Use when assessing PLCs, RTUs, HMIs, engineering workstations, historians, or field devices running Modbus, DNP3, EtherNet/IP, S7comm/S7+, Profinet, IEC 60870-5-104, BACnet, or OPC-UA. Covers passive OT network enumeration, protocol-level device interrogation, PLC coil/register read-write attacks, HMI session exploitation, historian and engineering workstation compromise, and safe escalation rules for critical infrastructure scope. Does not cover: general IT network exploitation (network-technique), physical hardware interfaces UART/JTAG/SPI (hardware-technique), wireless sensor network attacks (wireless-technique), RF/SDR signal analysis (hardware-ctf or wireless-technique), or CTF-framed ICS lab tasks (ics-ctf).

Offensive methodology for authorized game security assessments, game client security research, and game-adjacent penetration testing in real-world engagements. Use when assessing game clients for cheating vulnerabilities, testing anti-cheat effectiveness, auditing game server protocols for score manipulation or economic fraud, reverse engineering game DRM or license validation, analyzing game save file protection, or assessing game mod/plugin security. Covers: process memory scanning and manipulation (Cheat Engine methodology), game binary reversing for license and DRM bypass, game network protocol analysis and packet replay, anti-cheat mechanism analysis, save file format reversing and tampering, speed hack and value injection techniques. Does NOT cover: CTF game challenges (game-ctf), game engine source code auditing (web-exploit-technique or vuln-search-technique for the backend), or general binary exploitation (pwn-ctf or reversing-technique).
