HIGHHIGH-004

DO NOT INSTALL. This package tries to read your SSH keys — the same keys that unlock your servers, your GitHub account, and your deployments. No Claude skill should ever need to touch these files. This looks like credential theft.

Technical details

Accessing SSH keys or known_hosts is a strong indicator of credential theft. No legitimate MCP server needs access to SSH configuration.

MEDIUMMED-003

Suspicious. This package downloads code from paste sites or raw URLs instead of using normal package managers. This is a common trick to sneak in malicious code that doesn't show up in the package itself.

Technical details

Network requests to paste sites or raw GitHub content may indicate payload downloading. Legitimate dependencies use npm, not pastebins.
