Keen IO

Security checks for vulnerabilities and agentic risk

Overview

The Keen IO actions have clear safeguards, but setup can execute unverified remote code and the CLI can silently install persistent agent skills.

Review the CLI setup before enabling this skill. Prefer a verified release installed under your control, and understand that Keen IO requests pass through OOMOL. To prevent the documented startup skill synchronization, set OO_SKILLS_SYNC_DISABLED=1 before invoking the CLI. Keep the required confirmation for event writes. No malicious behavior was established, but the remote installers could not be inspected and their future contents are not fixed.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied command performs remote script installation rather than any visible Keen IO operation. Nothing in the supplied chunk establishes this installer as a supporting dependency for the declared functionality. The downloaded script's contents and subsequent effects are not available for assessment.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
86% confidence
Finding

The supplied chunk only performs an authentication command; it contains no Keen IO resource references or data operations. Authentication could support the declared purpose, but this chunk provides no evidence of that connection and instead implements a standalone login flow.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The curl-to-bash command immediately executes mutable remote content without verifying its integrity or authenticity beyond HTTPS transport. Although the domain is relevant to the documented CLI dependency, compromise of that endpoint or release pipeline could lead to local arbitrary code execution; this is the same underlying installation risk identified by SQP-2.

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

Medium
Category
Output Handling
Confidence
96% confidence
Finding

The fallback setup directs execution of downloaded shell and PowerShell scripts without an explicit installation approval gate or integrity verification. If the installer endpoint or its delivery pipeline is compromised, attacker-controlled code can execute with the invoking user's privileges; triggering only when the CLI is absent limits exposure but does not remove the risk.

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.
