Security audit

The Colony

Security checks for vulnerabilities and agentic risk

Overview

The Colony actions require confirmation for changes, but missing-tool recovery directs the agent to execute remote installers without separate approval or integrity checks.

Review and approve CLI installation separately, using a verified release where possible. OOMOL will mediate access to your connected Colony account, and posts, comments, and votes should retain the stated confirmation requirement. The remote installer and hosted connector implementations are outside this artifact review.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The fallback setup expands a service-data task into local execution of downloaded installer code without explicit user approval or integrity verification. Installing a required CLI is relevant to the skill rather than evidence of concealed malicious behavior, but a compromised installer endpoint could execute arbitrary code with the agent process's local privileges.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an HTTPS response directly into Bash executes whatever the installer endpoint supplies without a review or independent integrity check. HTTPS protects transport but does not prevent a compromised publisher or hosting system from delivering malicious code; the PowerShell setup command presents the same underlying risk.

Content

The setup workflow executes downloaded installation scripts without warning the user about system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

On a missing-CLI error, the instructions direct installation through shell or PowerShell execution without explaining the system changes or requiring approval. The conditional setup trigger reduces routine exposure, but the write-confirmation policy covers Colony actions rather than this local code execution.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
