AI Security Review

scanned 2mo ago · by lpm-firewall-ai

This is an automatic install-time delivery chain that plants an AI-directed prompt and induces broad, persistent modification of the consumer project's agent control surfaces. The behavior is not necessary for ordinary package installation and constitutes AI-agent control hijacking.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Installing the package, then a coding agent reading the automatically created KORAINIT.md.

Impact

It can hijack future coding-agent behavior in the consumer repository by creating or modifying agent instruction surfaces.

Mechanism

Postinstall prompt dropper leading to agent instruction-file writes.

Policy narrative

During npm installation, the package copies KORAINIT.md into the consumer project without consent. That file addresses any coding agent as an imperative instruction and tells it to run a command that writes a persistent managed block into AGENTS.md and other agent-specific instruction files. The sync code can create AGENTS.md even when absent and writes multiple agent control surfaces, causing later agents to receive package-authored directives.

Decision evidence

public snapshot

AI identified this as a dangerous AI-agent capability at 99.0% confidence with low false-positive risk.

Evidence for policy risk

The manifest automatically runs a postinstall script.
The postinstall script silently adds KORAINIT.md to the consuming project.
The dropped file directly instructs coding agents and directs them to modify their agent instruction files.
The sync implementation targets several agent control files and writes them in the project.

Evidence against

No runtime self-dependency is declared.
No package-owned network endpoint or credential exfiltration was confirmed.
