payload

A command for generating security-testing inputs for issues such as cross-site scripting, SQL injection, file inclusion, and command injection. It can also test inputs and assemble broader testing suites using Hexstrike tools.

In plain words
What is it for?
It is for authorized application security testing of web vulnerabilities, including generating, testing, and organizing payloads for a target.
Why use it?
It helps security testers create inputs suited to a vulnerability type and target context instead of writing every variation manually.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

payload 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 yesterday.

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.

Payload Generation

Type: $1 Context: $2

Generate targeted security testing payloads using Hexstrike AI tools.

Step 1: Load Tools

Use ToolSearch to load:

  • ai_generate_payload — contextual payload generation
  • ai_test_payload — payload testing and validation
  • ai_generate_attack_suite — comprehensive attack suite generation
  • advanced_payload_generation — payloads with WAF evasion techniques

Step 2: Identify Payload Type

Map the requested type to the appropriate category:

  • xss — Cross-site scripting (reflected, stored, DOM)
  • sqli — SQL injection (union, blind, time-based, error-based)
  • lfi — Local file inclusion / path traversal
  • rfi — Remote file inclusion
  • cmdi — Command injection (Unix, Windows)
  • ssrf — Server-side request forgery
  • ssti — Server-side template injection
  • xxe — XML external entity injection
  • nosqli — NoSQL injection (MongoDB, etc.)

Step 3: Generate Payloads

Run ai_generate_payload with:

  • The vulnerability type from step 2
  • Target context (URL, parameter, technology stack, WAF type)
  • Request WAF-evasion variants if a WAF is known

Step 4: Generate Attack Suite

If a broader test is needed, run ai_generate_attack_suite to create a comprehensive set of payloads covering multiple injection points and evasion techniques.

Step 5: Advanced Evasion

If the target is WAF-protected, also run advanced_payload_generation with evasion context for:

  • Encoding variations (URL, double-URL, Unicode, hex)
  • Case manipulation
  • Comment insertion
  • Whitespace alternatives
  • Concatenation techniques

Step 6: Test Payloads

Optionally run ai_test_payload against the target to validate which payloads succeed and which are blocked.

Step 7: Output

Present payloads organized by:

  • Clean payloads — no evasion, for testing without WAF
  • WAF bypass payloads — evasion techniques applied
  • Blind/out-of-band payloads — for targets with no visible response

Include usage instructions for each payload (where to inject, expected response).

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.

payload is a command published in the GitHub repository ogrodev/fsociety (20 stars, last pushed 5mo ago), licensed MIT. It adds 19 tokens to every session and 543 once invoked, about $0.0001 per session on Opus 5. 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.
