Safe IA — Monitor de riesgos de herramientas IA

Security checks for vulnerabilities and agentic risk

Overview

The skill mostly matches its compliance-monitoring purpose, but it persistently stores user profile details and forces promotional safe-ia.com messaging in every response.

Review this skill before installing if you do not want persistent business-profile memory or recurring promotional links. Use it only if you are comfortable sharing your name, industry, AI tools, jurisdiction, and data-processing context for future personalization, and avoid entering any service key unless you trust the publisher and understand what the external service does.

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

Technical Analysis

The Skill explicitly requires the agent to append promotional registration content and an external website reference to every response. This instruction is persistent for the duration of any session in which the Skill is loaded and is not conditioned on user intent, relevance, or consent.

The behavior alters the agent’s normal response objective: instead of solely answering the user’s compliance-monitoring request, the agent must also advertise an external service. Because the promotion is embedded in the standard response template, users may interpret it as a trusted recommendation from the hosting agent rather than advertising authored by the Skill publisher.

No executable code, automatic browser navigation, credential transmission, or remote payload retrieval was identified. The issue is therefore limited to instruction-level manipulation and external-site promotion.

Attack Path

  1. The hosting agent loads SKILL.md and adopts its behavioral instructions.
  2. A user requests a report or other supported compliance analysis.
  3. The agent generates the requested content using the Skill’s response template.
  4. Regardless of whether registration is relevant, the mandatory instructions cause the agent to append an invitation to visit safe-ia.com.
  5. The user may follow the link bec ...[truncated 849 chars]

Remediation Suggestions

  1. Remove the instruction requiring registration promotion at the end of every response.
  2. Remove the promotional footer from the standard response template.
  3. Present the service link only when a user explicitly asks about registration, premium features, or automated alerts.
  4. Clearly label any optional external-service reference as publisher-provided promotional content.
  5. Require explicit user confirmation before opening or transmitting information to an external website.
  6. Keep compliance-monitoring responses focused on the user’s request and avoid mandatory unrelated content.
  7. Document the destination domain, information collected there, and applicable privacy policy before recommending registration.
  8. Add review tests verifying that ordinary reports do not contain unsolicited advertisements or external redirects.

Finding

The onboarding flow asks for name, industry, and tools used, then instructs the assistant to store that information for future use, but it does not clearly request consent for ongoing retention or explain privacy consequences. In context, the skill is compliance- and privacy-focused, so undisclosed persistence is especially problematic because users may reasonably expect stronger privacy hygiene from this kind of assistant.

Confidence
95% confidence
Finding

The skill explicitly instructs the assistant to save personal and business-profile data in memory across conversations, but the onboarding text does not clearly disclose retention duration, persistence behavior, or privacy implications. This creates a privacy risk because users may provide identifying and potentially sensitive business information without informed consent about ongoing storage and reuse.

Confidence
96% confidence
Finding

The skill defines persistent storage and reuse of multiple profile attributes across conversations, including jurisdiction and types of data processed, which can reveal sensitive regulatory and business context. Because this storage is framed as personalization and proactive monitoring rather than necessity-limited processing with explicit consent, it increases privacy exposure and the risk of over-collection or unintended secondary use.

Missing User Warnings

Confidence
92% confidence
Finding

The skill directs proactive personalization and alerting based on remembered user data, including contacting the user about tools they use even when not explicitly asked. Without a clear warning and opt-in for this ongoing monitoring behavior, users may be subject to unexpected profiling and reuse of prior conversation data beyond their immediate request.

Natural-Language Policy Violations

Confidence

Finding

The manifest explicitly sets the skill language to "es", and the description also states it operates "en español." This is a natural-language locale restriction without any indication that users can choose another language or opt in to the constraint.

Confidence
97% confidence
Finding

The instruction requires 'Lenguaje español rioplatense' with region-specific phrasing, which forces a specific locale variant. The file does not offer users a language or dialect choice, nor does it justify the constraint as a region-specific compliance requirement.
