portscan

A command that checks a host or list of hosts for open network ports, including services that do not use web traffic. It can also use a passive Shodan-backed check that sends no packets.

In plain words
What is it for?
Mapping a host's service exposure, checking selected or common ports, scanning a host list and exporting results as JSON.
Why use it?
A web-only security check can miss exposed services such as SSH, databases, Redis or Docker. This reveals those additional entry points and highlights potentially risky ones.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

portscan scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/portscan

The main recon pipeline is HTTP-only (httpx / nuclei / katana), so open ports that don't speak HTTP are invisible. This maps the full service surface and pulls the interesting, often-forgotten ports to the top — the ones that turn into instant wins.

Usage

/portscan target.com                 # top-100 ports
/portscan target.com --top 1000
/portscan target.com -p 22,6379,27017
/portscan -l recon/target.com/subdomains/resolved.txt --json
/portscan target.com --smap          # passive (Shodan) — no packets sent

Run directly:

tools/port_scanner.py target.com --top 1000

Tooling

Wraps ProjectDiscovery's naabu (fast SYN/CONNECT scan), falling back to smap (Shodan-backed, sends no packets — handy when active scanning is out of scope). Both are registered in tools/external_arsenal.sh. If neither is installed the command prints install hints and exits cleanly.

What it flags

Any open, non-web port with a known attack surface, e.g.:

Port Service Why it matters
6379 redis unauth → RCE / full data dump
2375 docker unauth Docker API → instant host RCE
27017 mongodb unauth → database dump
9200 elasticsearch unauth → index dump
3306 / 5432 / 1433 mysql / postgres / mssql database exposed to the internet
3389 rdp weak creds / BlueKeep-class
445 smb null session / EternalBlue-class

Web ports (80/443/8080/…) are counted but not flagged — the rest of the pipeline already covers those.

Chain

/portscan → non-web service found → pivot with the matching technique (e.g. unauth Redis → CONFIG SET webshell, exposed DB → dump, Docker API → container escape). Feed resolved subdomains from /recon straight in with -l.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

portscan is a command published in the GitHub repository Awarexone/Agentic-Bug-Hunter (4,651 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 552 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
