wazuh-malware-detection

wazuh-malware-detection is a skill for Claude Code from gensecaihq/Wazuh-Autopilot. It costs 63 tokens per session (1,372 once invoked), scanned A, original, MIT.

A guide for interpreting Wazuh malware signals from sources such as VirusTotal, ClamAV, rootcheck, Microsoft Antimalware and Sysmon. Wazuh combines these sources rather than using one built-in malware scanner.

In plain words
What is it for?
Use it to investigate malware, rootkits and suspicious files or programs, review file-hash results and prepare enrichment or containment hand-offs.
Why use it?
It helps judge what an alert actually means and account for differences in detection quality and false positives. It separates useful evidence from weak or incomplete signals before response actions are handed off.

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

wazuh-malware-detection 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.

Wazuh Malware Detection

Wazuh has no single malware engine; it aggregates several sources. Know which one fired, because their reliability differs.

Sources (stock ruleset)

Source Rules / group Reliability notes
VirusTotal integration (FIM hash lookups) group virustotal; rule 87105 (level 12, engines detected the file), rule 87104 (level 3, no positives), rule 87103 (level 3, not in VT database), rule 87101 (level 3, API rate limit), rule 87102 (level 3, check credentials) Good signal when many engines agree (virustotal.positives); "not in database" on a new executable in a temp path is itself suspicious
Rootcheck group rootcheck; rule 510 (level 7, host-based anomaly), rule 513 (level 9, Windows malware detected), rule 518 (level 9, Windows adware/spyware), rule 521 (level 11, possible kernel level rootkit), rule 519 (level 7, vulnerable web application found) Signature/heuristic checks; rule 510 is a parent — read the child or full_log for the specific finding. Known false positives on some kernels/containers
ClamAV (if deployed) group virus; rule 52502 (level 8, "ClamAV: Virus detected") Signature-based, good for known malware on Linux file servers
Microsoft Antimalware / Defender events group mse; rule 7703 (level 5, error event) Only if the Defender event channel is collected
Sysmon detections groups sysmon_eid1_detections, sysmon_eid3_detections, sysmon_eid7_detections, sysmon_eid8_detections, sysmon_eid10_detections, sysmon_eid11_detections, sysmon_eid13_detections Behavioural. Examples: rule 92213 (level 15, executable dropped in a folder commonly used by malware), rule 92104 (level 15, suspicious binary created network connection), rule 92900 (level 12, LSASS accessed with read permissions), rule 92400 (level 12, possible code injection on explorer.exe)
Office 365 rule 91700 (level 14, detected malware in file), rule 91556 (level 12, phishing and malware events from Exchange Online Protection / Defender) Cloud mailbox/file detections

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.
