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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00097 | $0.02594 |
| Opus 5 | $0.00048 | $0.01297 |
| Sonnet 5 | $0.00019 | $0.00519 |
| Haiku 4.5 | $0.00010 | $0.00259 |
Grade A, and why
abusing-dpapi-for-credential-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 5d 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.
This is a copy
100% identical to abusing-dpapi-for-credential-access — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Abusing DPAPI for Credential Access
Legal Notice: This skill is for authorized penetration testing, red-team engagements, and educational purposes only. Extracting credentials from systems you do not own or lack explicit written authorization to test is illegal and may violate computer fraud and abuse laws. Always operate within a signed rules-of-engagement and document every action.
Overview
The Windows Data Protection API (DPAPI) is the operating system's built-in symmetric-encryption service that applications use to protect secrets at rest: saved RDP and Windows Credential Manager credentials, web and Wi-Fi credentials in the Credential Vault, browser saved logins and cookies (Chrome/Edge), KeePass keys, certificate private keys, and Scheduled Task passwords. DPAPI derives a per-user (or per-machine) master key from the user's password (or the machine account secret), and that master key encrypts individual "DPAPI blobs." The encrypted master keys live under %APPDATA%\Microsoft\Protect\<SID>\ (user) and %WINDIR%\System32\Microsoft\Protect\ (machine).
Red teamers abuse DPAPI to recover plaintext secrets after gaining a foothold, mapping to MITRE ATT&CK T1555.004 (Credentials from Password Stores: Windows Credential Manager). There are three primary decryption paths:
- Online / context-based — running as the target user, DPAPI APIs (
CryptUnprotectData) transparently decrypt the user's blobs. SharpDPAPI's/unprotectflag uses this. - Offline with the user password or NTLM hash — decrypt the user's master keys with
/password:or/ntlm:, then decrypt the blobs offline (great for triaged files pulled from a host). - Domain-wide with the DPAPI backup key — Domain Admins can extract the domain's RSA DPAPI backup key (
.pvk) once, then decrypt any domain user's master keys forever, online or offline, with/pvk:.
The canonical tooling is SharpDPAPI (GhostPack, a C# port of Mimikatz DPAPI functionality) for Windows, SharpChrome for browser secrets, and Mimikatz (dpapi::*) as the original implementation. On Linux, Impacket's dpapi.py and donpapi perform remote/offline triage.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
