Security audit

SigmaLifting CLI

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for using SigmaLifting CLI, but its documented install path asks users to globally install mutable remote code from GitHub.

Review the CLI source and prefer a pinned commit, signed release, exact package version, or project-local install before using this skill. Use SIGMALIFTING_HOME or --store-root for test work so training data changes stay in an intended local store.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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
