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 | $0.00077 | $0.00751 |
| Opus 5 | $0.00039 | $0.00376 |
| Sonnet 5 | $0.00015 | $0.00150 |
| Haiku 4.5 | $0.00008 | $0.00075 |
Grade C, and why
hunting-credential-dumping-activity scanned grade C 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 7d 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.

Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.
attempts to read LSASS memory or dump credentials. What it actually says
Hunting Credential Dumping Activity
When to Use
- You have Sysmon ProcessAccess (Event ID 10) and/or process-creation telemetry and want to detect attempts to read LSASS memory or dump credentials.
- You are investigating post-exploitation credential theft.
Do not use this to dump credentials yourself — it analyzes telemetry of such activity. Legit security tools also touch LSASS; corroborate before alerting.
Prerequisites
- Sysmon EID 10 events (with TargetImage, GrantedAccess, SourceImage) and/or EID 1 process events.
Workflow
Step 1: Hunt LSASS access and dumping patterns
python scripts/analyst.py hunt events.csv
Flags EID 10 events where TargetImage is lsass.exe with high-risk GrantedAccess masks
(0x1010, 0x1410, 0x143a, 0x1438), and process events showing comsvcs.dll,MiniDump,
procdump ... lsass, rundll32 ... MiniDump, or known tool names.
Step 2: Reduce false positives
De-prioritize known security agents (EDR, AV) as the SourceImage; weight unsigned or unusual
source processes.
Step 3: Confirm
Correlate with file writes of .dmp files and subsequent off-host transfer.
Step 4: Operationalize
Write a Sigma rule for LSASS access masks and comsvcs MiniDump.
Validation
- LSASS access flags are based on access mask, not mere access by trusted tools.
- comsvcs/procdump/rundll32 MiniDump patterns are detected from command lines.
- Findings map to ATT&CK T1003.001/.002.
Pitfalls
- Many legitimate tools open LSASS — access mask + source-image context is essential.
- Attackers renaming tools; rely on behavior (mask, MiniDump export) not just names.
- Direct-syscall dumpers that avoid the usual API and reduce telemetry.
References

references/api-reference.mdfor the hunter. - ATT&CK T1003.001 and Sysmon EID 10 (linked in frontmatter).
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.

hunting-credential-dumping-activity is a skill published in the GitHub repository meltedinhex/analyst-ai-pack (22 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 77 tokens to every session and 751 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 1 finding (harvests environment variables). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
