AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The automatic postinstall global installation is a concrete install-hook risk. Source inspection found no self-dependency, concealed payload, credential harvesting, or exfiltration, so the evidence does not support a malicious classification.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

npm installation with no detected supported AI CLI; configuration changes require runtime custom-LLM input.

Impact

Changes global npm state without an explicit install command and can add credentials to an AI CLI configuration during normal use.

Mechanism

Postinstall global dependency installation and runtime OpenCode configuration writes.

AI rationale

Network endpoints1

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

The package runs a postinstall hook automatically during npm installation.
That hook installs opencode-ai globally when no supported AI CLI is detected.
The global installation is enabled by default; it is only skipped when an environment variable is set.
The package can later write a custom provider and API key into the user's OpenCode configuration.

Evidence against

The installer names the exact command and dependency rather than hiding or obfuscating it.
No self-dependency, credential harvesting, secret exfiltration, or unrelated network endpoint was found.
Configuration writes occur in runtime functions for user-supplied custom LLM settings, not in the install hook.
