Security audit

Luno

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a coherent read-only Luno connector, but its fallback setup tells the agent/user to execute a remotely fetched installer script without verification.

Review the oo CLI installation path before installing. Prefer verified/manual installation from trusted OOMOL documentation, and only connect Luno if you are comfortable granting OOMOL connector access to read account balances and order information.

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

External Script Fetching

Finding

The skill instructs users to install software via curl ... | bash, which executes a remotely fetched script without prior verification. Because skill content must be treated as adversarial, this creates a direct supply-chain and remote code execution risk if the upstream host, network path, or install script is compromised.

Finding

The description says to use this skill for "ANY Luno request," including any task that "involves Luno." For a markdown skill description, this activation scope is very broad and does not provide clear constraints or exclusion conditions, which could cause unintended invocation for loosely related requests.
