Security audit

The Swarm

Security checks for vulnerabilities and agentic risk

Overview

The searches fit the skill’s purpose, but a routine request can trigger an unverified software installer without asking you first.

Review the setup behavior before installing. Preinstall a reviewed, version-pinned CLI and require approval before any installer fallback runs. Check whether the CLI will install or update other agent skills, and understand that OOMOL mediates access to your connected account. The Review verdict concerns insufficient control over installation; the inspected artifact does not establish malicious intent.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command performs remote installer execution, not a The Swarm search or read operation. No connection is shown between this installer and the declared service, so it cannot be established as a supporting implementation detail. The installer contents are not supplied, so its further effects cannot be determined.

Description-Behavior Mismatch

MCP Tool Poisoning
Confidence
80% confidence
Finding

Authentication can be a supporting implementation detail, but the supplied chunk consists entirely of a login command and provides no evidence that it authenticates to The Swarm or supports the declared data-access functionality. Its demonstrated primary behavior therefore differs from the declared purpose.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

The command pipes a mutable remote script directly into Bash without a pinned version or independent integrity verification. If the distribution endpoint or release infrastructure is compromised, attacker-controlled code executes with the agent's local privileges; HTTPS alone does not protect against a compromised publisher. The PowerShell installation example has the same underlying risk.

Fallback setup executes a remotely downloaded installer without warning about local system changes.

Medium
Category
Output Handling
Confidence
97% confidence
Finding

When the CLI is missing, the skill instructs the agent to execute a downloaded installer without first obtaining approval for local software installation. A read-only service request can therefore lead to code execution and system changes under the agent's local permissions; the missing-command condition limits when this happens but does not provide informed authorization.

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.
