post-exploit

post-exploit is a skill for Claude Code, Codex from roodlicht/accans-sec-skills. It costs 56 tokens per session (3,232 once invoked), scanned B, original, no licence file.

A guide to actions attackers may take after gaining access to Windows, Linux, or cloud systems. It groups these actions using MITRE ATT&CK, a catalogue of known attack techniques, and includes defensive countermeasures and detection points.

In plain words
What is it for?
Use it to study privilege escalation, credential theft, system discovery, movement between systems, persistence, and hiding activity, alongside defensive responses.
Why use it?
It gives security teams a structured way to understand what can happen after an intrusion and where to detect or stop it.

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 B, and why

post-exploit scanned grade B with 2 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 8d 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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- Misconfigured sudo (`sudo -l` as a probe), wildcards in sudoers, suid binaries.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Reaches for credential filesmediumPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

- Linux: `/etc/shadow` (after privesc), SSH keys, `.bash_history`, `.netrc`, `.aws/credentials`, `.kube/config`.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
