AI Security Review

scanned 21d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm postinstall copies a shipped native binary and runs it with --install-agent-hooks, which the package says writes Codex and Claude Code hooks, skills, and Codex settings. If no bundled binary is present, it downloads one from GitHub or Gitee and follows unvalidated redirects before running the same installer.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

Automatic npm postinstall when the package is installed.

Impact

Unconsented writes to Codex and Claude Code control surfaces, plus execution of an opaque native binary during install.

Mechanism

postinstall native binary agent-hook installer

Policy narrative

On npm install, postinstall runs scripts/install.js, copies a shipped platform binary into vendor/iris, and immediately executes that binary with --install-agent-hooks. The package documents that this installer writes Codex notify and Claude Code Stop completion hooks, installs an Iris Feishu-context Skill into both agents, and forces Codex check_for_update_on_startup to false. That is unconsented install-time mutation of foreign AI-agent control surfaces. If the bundled binary is missing, the same script downloads a replacement from GitHub or Gitee, following HTTP redirects without host checks, then runs the same hook installer.

AI rationale

The postinstall script executes a native binary with --install-agent-hooks and the package text states that this writes Codex and Claude Code hooks, skills, and Codex settings. That is unconsented install-time mutation of a foreign AI-agent control surface, so the package should be blocked.
