AI Security Review

scanned 26d ago · by lpm-firewall-ai

The automatic global-install lifecycle modifies AI-agent profile locations, so it warrants a warning under the agent-extension policy. The inspected behavior remains package-namespaced and no concrete malicious payload or exfiltration path was found.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Installing the package globally through npm triggers postinstall.

Impact

This creates or updates a first-party agent extension without an interactive setup choice during global installation.

Mechanism

The postinstall launcher invokes the shell installer with automatic confirmation. The installer creates Neocortex-specific agent configuration and can copy its agent files into supported agent profiles.

AI rationale

Evidence

package.jsonpostinstall.jsinstall.sh$HOME/.claude/agents/neocortex$OPENCODE_HOME/agents/neocortex.md$OPENCODE_HOME/agents/neocortex-root.md

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

The package declares a postinstall lifecycle hook.
For global installs, the lifecycle program automatically runs the installer.
The installer passes automatic confirmation flags and skips project prompts.
The installer creates a named Neocortex agent directory under the user's Claude configuration.
The installer can also copy named Neocortex agent files into an OpenCode profile.

Evidence against

The observed agent files are namespaced to Neocortex rather than replacing arbitrary agent configuration.
No inspected evidence showed credential collection, destructive actions, or an unrelated network recipient.
