ClawHub Security Signals

🦀 ClawHub | 📝 OpenClaw Blog | 🤗 Hugging Face Blog | 📄 Paper | 📄 Pre-Print

ClawHub Security Signals is a sanitized, MIT-licensed security-signals dataset for public OpenClaw agent skills. It captures how an agent-skill registry evaluates trust, provenance, bundled code, and scanner evidence at scale.

This dataset was presented in the paper ClawHub Security Signals: When VirusTotal, Static Analysis, and SkillSpector Disagree.

This Hugging Face dataset repository hosts 67,453 latest public ClawHub skill versions with redacted SKILL.md content, sanitized bundled files where present, ClawScan registry verdicts, and supporting scanner evidence from VirusTotal, static heuristic analysis, and NVIDIA SkillSpector.

Important framing: scanner positives are evidence, not ground truth. SkillSpector findings are semantic agentic-risk advisories, not accusations or install-blocking verdicts by themselves. A ClawScan suspicious verdict means "review before trusting," not "malicious."

The core research signal is scanner disagreement: VirusTotal, static analysis, and SkillSpector rarely flag the same skills, and their disagreement is structured by attack surface. Agent-skill security therefore needs layered governance rather than a single-scanner allow/block decision.

Safety

This dataset is sanitized for security research. It excludes raw private package contents, storage identifiers, private user identifiers, emails, raw secrets, and runnable private artifacts. SKILL.md text and bundle-file content are redacted upstream before snapshot export, then checked again during private prep for email addresses, token-like strings, credential-like assignments, auth headers, private keys, and other secret-like values.

The dataset is a silver-standard corpus: clawscan_verdict is the registry's automated operational verdict, not a human-adjudicated ground-truth label.

ClawScan Verdicts

clawscan_verdict is the final registry-style label. It is produced after ClawScan weighs scanner evidence, provenance, metadata, and moderation context.

Verdict	Rows	Share
clean	41,743	61.9%
suspicious	25,504	37.8%
malicious	206	0.3%

The suspicious class is intentionally broad. It includes skills with unclear disclosure, overbroad authority, scanner disagreement, risky defaults, or enough blast radius that a user or registry should review the Skill Card before trusting the skill.

Scanner Coverage

A scanner is treated as positive when its status is suspicious or malicious. clean, stale, error, and missing statuses are non-positive for overlap analysis.

Scanner context	Rows with source	Source coverage	Positive rows	Positive share
VirusTotal	65,873	97.66%	5,225	7.75%
Static analysis	66,185	98.12%	4,434	6.57%
SkillSpector	66,222	98.18%	32,856	48.71%

VirusTotal has resolved clean/suspicious/malicious status for 65,640 rows; among those resolved rows, 8.0% are positive. SkillSpector resolves to clean or suspicious for 66,206 rows; among those resolved rows, 49.6% are advisory-positive.

Scanner Disagreement

Of the 67,453 rows, 35,600 (52.8%) carry at least one positive scanner signal. Most positives are not corroborated by another scanner.

Positive pattern	Rows	Share
None	31,853	47.22%
VirusTotal only	1,821	2.70%
Static only	805	1.19%
SkillSpector only	26,527	39.33%
VirusTotal + Static	118	0.17%
VirusTotal + SkillSpector	2,818	4.18%
Static + SkillSpector	3,043	4.51%
All three	468	0.69%

Pairwise Jaccard overlap never exceeds 0.104, and Cohen's kappa remains close to zero (0.045-0.082). This is the central trust finding: static analysis, malware reputation, and semantic agentic-risk analysis inspect different attack surfaces.

Verdict-Conditioned Signals

Verdict	Rows	VirusTotal+	Static+	SkillSpector+	No positive
clean	41,743	1,847 (4.4%)	1,355 (3.2%)	13,633 (32.7%)	26,470 (63.4%)
suspicious	25,504	3,228 (12.7%)	3,053 (12.0%)	19,209 (75.3%)	5,333 (20.9%)
malicious	206	150 (72.8%)	26 (12.6%)	14 (6.8%)	50 (24.3%)

SkillSpector is the dominant positive source in the review-needed region, while VirusTotal dominates the malicious-verdict region. This inversion is expected: SkillSpector reasons about semantic agentic risk and disclosure, while VirusTotal is stronger for bundled-code malware evidence.

SkillSpector Risk Categories

SkillSpector categories are row-level advisory occurrences. A single skill can have multiple categories.

Category	Rows
MCP Least Privilege	9,641
MCP Tool Poisoning	5,084
Data Exfiltration	2,192
Dangerous Code Execution	1,629
Rogue Agent	1,428
Supply Chain	1,336
Data Flow	976
Privilege Escalation	792
Tool Misuse	647
Excessive Agency	511

These are not abuse labels. They describe authority, scope, tool semantics, execution risk, data flow, and disclosure properties that may be legitimate when documented and bounded.

Static Finding Highlights

The most common static reason codes are:

Static reason code	Rows
suspicious.dangerous_exec	1,428
suspicious.env_credential_access	1,298
suspicious.exposed_secret_literal	1,219
suspicious.dynamic_code_execution	451
suspicious.prompt_injection_instructions	433
suspicious.install_untrusted_source	250
suspicious.destructive_delete_command	201
suspicious.potential_exfiltration	181
suspicious.insecure_tls_verification	166
suspicious.secret_argv_exposure	121

Splits

Splits are deterministic.

Split	Rows	Share
train	47,262	70.07%
validation	10,076	14.94%
test	6,747	10.00%
eval_holdout	3,368	4.99%

Data Format

All data files are JSON Lines.

Core columns:

• id: stable opaque row id derived from the source artifact reference.
• skill_slug: owner-qualified public ClawHub skill slug when available, otherwise the unqualified public slug.
• skill_version: public skill version.
• skill_md_content: redacted SKILL.md markdown content from the source snapshot.
• skill_bundle_content: redacted authored bundle files excluding SKILL.md and generated skill-card.md; sha256 and sizeBytes describe the emitted redacted content.
• clawscan_verdict: final ClawScan verdict: clean, suspicious, or malicious.
• clawscan_confidence: ClawScan confidence when present.
• clawscan_model: ClawScan model name when present.
• clawscan_summary: redacted ClawScan summary when present.
• static_status, static_finding_count, static_reason_codes: static scanner summary.
• virustotal_status, virustotal_*_count: VirusTotal summary counts.
• skillspector_status, skillspector_score, skillspector_severity, skillspector_issue_count, skillspector_issue_codes, skillspector_issue_categories: SkillSpector summary fields.
• clawscan_context: supporting scanner context used by ClawScan, currently static, virustotal, and skillspector when those inputs are present.
• split: deterministic split name.

clawscan_verdict is the only label-like top-level field. Supporting scanner outputs stay separate so consumers can distinguish ClawScan's final verdict from the scanner inputs that informed it.

Croissant

Hugging Face can expose this dataset through the Croissant metadata endpoint when the dataset viewer has converted the splits to Parquet. The dataset card includes the mlcroissant tag so the Hub surfaces Croissant-compatible tooling.
