Security checks across malware telemetry and agentic risk

Overview

This is an instruction-only Instagram downloader that openly uses Cobalt, with ordinary privacy and safe-input cautions but no evidence of hidden or malicious behavior.

Install only if you are comfortable sharing the Instagram link with Cobalt. Use it for public or non-sensitive links, avoid providing Instagram credentials or cookies, and ensure the agent validates the URL as an Instagram link and constructs the curl request safely rather than blindly shell-interpolating unusual input.

Vague Triggers

Medium
Confidence
81% confidence
Finding
The skill activates on any Instagram link with no clear scope limits, exclusions, or confirmation step. Broad triggers increase the chance that normal user content is automatically processed and sent into a download workflow, which can cause unintended handling of third-party URLs and privacy-sensitive content.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill instructs the agent to send user-provided Instagram URLs to an external service without an explicit warning or consent step. Even if the submitted value is 'just a URL', it still discloses user activity and requested content to a third party, creating a privacy and data-sharing risk.
