Security audit

iaiops-fab

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for fab equipment diagnostics, but it also exposes industrial data export and publish capabilities without clearly documented destination, approval, or scope controls.

Review this skill before production use. Install it only where the iaiops package is trusted, network access is segmented, allowed historian or UNS destinations are explicitly configured, and export or publish actions require the same approval and audit discipline as equipment writes.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Natural-Language Policy Violations

Medium

Confidence
93% confidence
Finding

The main instructional content begins in Chinese and continues throughout the skill description, which imposes a specific language/locale on users. The file does not indicate that Chinese is optional, nor does it offer an alternative language path or explicit user opt-in.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill repeatedly markets itself as read-first and MOC-gated for writes, but the documented toolset also exposes outbound data-moving functions such as historian_push, export_data, stream_publish, and uns_publish without equally explicit approval, destination, and scope controls in the manifest. In an industrial fab context, uncontrolled export or publish actions can leak production, recipe, alarm, or asset data to external systems and undermine operator trust in the documented safety model.

Context-Inappropriate Capability

Category
Not specified by scanner
Confidence
72% confidence
Finding

The manifest centers on SECS/GEM, OPC-UA, and cross-protocol operational analysis such as OEE, asset inventory, downtime RCA, and data quality. The additional capabilities compliance_mapping, compliance_frameworks, compliance_dengbao_levels, compliance_report, and compliance_evidence_bundle introduce a governance/compliance reporting function that is not clearly part of that stated mission. This appears to extend the skill into a separate assurance/reporting domain.
