AI Security Review

scanned 1mo ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installation drops an agent-directed instruction file into the consumer project. Following its instructions modifies broad AI-agent control files with a managed block.

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.

AI rationale

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.
