pt-maintaining-access

pt-maintaining-access is a skill for Claude Code, Codex from santosomar/ethical-hacking-agent-skills. It costs 45 tokens per session (391 once invoked), scanned A, original, Apache-2.0.

A guide for testing whether an attacker could keep access and move between systems after an initial compromise, within strict authorization limits.

In plain words
What is it for?
Use it to assess persistence, session resilience, trust relationships, shared credentials, network separation, detection, response, and cleanup.
Why use it?
It reveals whether access survives common changes and whether security teams can detect and contain the activity.

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

pt-maintaining-access 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 11d 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

Pen Test Maintaining Access

Authorized Use Only

Persistence simulation requires explicit approval. Prefer temporary, reversible techniques and remove all artifacts during cleanup. Never leave backdoors, accounts, or scheduled tasks in place after testing.

Objectives

  1. Determine whether access can survive control changes and reboots.
  2. Assess lateral movement opportunities from compromised context.
  3. Measure detection and response effectiveness.

Workflow

  1. Confirm persistence permissions:
    • Allowed mechanisms
    • Maximum dwell time
    • Mandatory cleanup expectations
  2. Simulate persistence safely:
    • Use low-risk, reversible methods appropriate to target class
    • Validate whether persistence survives expected environmental changes
  3. Evaluate lateral movement opportunities:
    • Trust relationships, token reuse, shared credentials, weak segmentation
    • Keep movement minimal and auditable
  4. Test detection/response:
    • Document whether controls trigger and how quickly teams react
    • Capture gaps in telemetry and containment
  5. Cleanup and verify:
    • Remove all test artifacts
    • Recheck system state to confirm rollback

  • Evidence includes timeline from initial foothold to cleanup.
  • Detection gaps are mapped to concrete control improvements.

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.
