Epstein Files Search

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward command-line search wrapper for a public Epstein document index, with expected external queries and no persistence or local data access found.

Install only if you are comfortable with your search terms being sent to the DugganUSA analytics API. The reviewed artifact does not show local data collection, credential use, persistence, or destructive actions, but it depends on a third-party search endpoint for results.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
91% confidence
Finding

The skill explicitly requires network-capable binaries (node, curl) and is designed to query external DOJ/DugganUSA endpoints, but it does not declare any tool scope such as permissions or allowed-tools. This creates a mismatch between documented behavior and enforcement, increasing the risk that an agent runtime will grant broader-than-necessary network or execution access without clear user-visible constraints.

Content

No source excerpt is available for this finding.

External Transmission

Medium
Category
Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
