KickoffLabs

Security checks for vulnerabilities and agentic risk

Overview

This appears to be a legitimate KickoffLabs reader skill, but its setup instructions can run an unverified remote installer and its routing language is broader than its listed read-only actions.

Review the installer path before installing. Prefer installing the oo CLI from a verified package or documented signed method, and treat this skill as suitable for reading KickoffLabs campaign data unless you have separately reviewed any connector actions beyond the three listed reads.

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

High
Category
Supply Chain
Confidence
98% confidence
Finding

The skill instructs the operator to install software via a remote script piped directly into a shell (curl ... | bash). This is dangerous because it executes unverified code fetched at runtime, creating a supply-chain and arbitrary code execution risk if the remote endpoint, network path, or distribution mechanism is compromised.

Description-Behavior Mismatch

Confidence
96% confidence
Finding

The manifest and description frame the skill as being for 'searching and reading data,' but the body explicitly instructs operators to use a generic connector interface and discusses write/destructive actions. This creates a capability mismatch that can mislead users or higher-level agents into invoking a skill believed to be read-only when it may execute state-changing operations.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The invocation text says to use this skill for 'ANY KickoffLabs request,' which is overly broad and can cause unintended activation outside the narrow read/search context claimed elsewhere. Overbroad routing increases the chance that sensitive or state-changing tasks are delegated to a generic shell-backed connector skill without sufficient user intent verification.
