Security audit

chill.institute

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small browser-workflow guide for sending user-selected chill.institute results to put.io, with disclosed account use and no bundled executable code.

Install only if you intentionally want an agent-assisted chill.institute to put.io workflow. Keep login in the browser, do not provide passwords in chat, and review any selected content before the agent sends it to your put.io account.

A.I.G

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: Use chill.institute (web UI) to search for content and click “send to put.io” (best paired with the putio skill) — set sail, pick the best 1080p/x265 loot, and ship it.

# chill.institute

Use **chill.institute** via an interactive browser session to find an item and send it to put.io.

If you have both skills installed (**chill-institute** + **putio**), the workflow is much smoother: chill.institute launches the transfer, and putio verifies/monitors it from the CLI.

## Prereqs

- User must be logged in to **chill.institute** (put.io OAuth in the browser).
- The `putio`

Finding
YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).
