Tomba Contact Intelligence

Security checks for vulnerabilities and agentic risk

Overview

This is a small, disclosed Tomba helper skill for contact lookup workflows, with privacy considerations but no hidden or destructive behavior found.

Install this only if you are comfortable using Tomba for contact intelligence and have authority to submit the relevant emails, domains, LinkedIn URLs, phone numbers, or prospecting criteria. Avoid sending sensitive, regulated, confidential, or unnecessary personal data through lookups unless your data-handling obligations allow it.

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

Missing User Warnings

Finding

The README explicitly promotes contact discovery, email verification, enrichment, phone lookup, and company research on personal/contact data, but it provides no warning that user-supplied emails, LinkedIn URLs, domains, or phone numbers will be transmitted to a third-party service. This creates a privacy and compliance risk because operators may unknowingly submit personal data to Tomba without consent, notice, or data-handling constraints.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill directs use of external Tomba tools for contact discovery, verification, enrichment, phone lookup, and company research, but it does not warn users that personal and company data may be transmitted to a third-party service. This creates a real privacy and data-governance risk because users may submit sensitive PII, prospect lists, or internal targets without informed consent or handling guidance.
