@claudiolabs/claudin@1.1.22: Suspicious npm security report | LPM Firewall

Decision evidence

public snapshot

AI called this Suspicious at 66.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

npm postinstall runs install.cjs and overwrites bin/claudin.exe with a native binary from optional platform packages.
The CLI can copy Claude Code tokens, settings, skills, agents, plugins, and MCP config from ~/.claude into ~/.claudin.
Minified AWS code performs an HTTP GET to the EC2 metadata host 169.254.169.254.
Protocol-handler code still drops a Claude Code URL Handler app under the user Applications folder.
The Node entry loads a huge minified coding-agent bundle, and the matching native binaries are not in this tarball.
Static coverage of that minified tree is incomplete, so extra hidden behavior cannot be fully ruled out.

Evidence against

install.cjs does not make network calls and only writes under this package bin directory.
optionalDependencies are same-version platform packages with different names, not a nested self-name release.
bin/claudin.exe in this tarball is a short Node stub that delegates to cli-wrapper.cjs.
Claude Code import is a Migrate now or Skip dialog, not the npm hook.
IMDS access is AWS metadata-style code consistent with Bedrock-style providers.
