sealclaw@2026.9.2

Multi-channel AI gateway with extensible messaging integrations

AI Security Review

scanned 28d ago · by lpm-firewall-ai

npm installation automatically modifies a hoisted third-party AI dependency and removes legacy OpenClaw state directories. These actions occur without a user command after install.

Static reason

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

Trigger

Installing sealclaw with npm lifecycle scripts enabled.

Impact

It can alter shared dependency behavior and delete existing agent runtime state.

Mechanism

Postinstall dependency patching and user-state deletion.

Attack narrative

On npm installation, the package runs a postinstall hook. That hook searches upward through parent directories for a hoisted copy of @mariozechner/pi-ai, replaces source anchors in two provider files, and writes the altered code. A second hook also recursively deletes legacy runtime dependency state under OpenClaw home directories. The automatic modification of a foreign AI dependency and deletion of user agent state, combined with the SealClaw name while retaining OpenClaw identity, is an unconsented install-time control-surface mutation.

AI rationale

Direct source inspection confirms automatic postinstall modification of a foreign AI dependency and recursive deletion of user agent state. This is concrete install-hook abuse, not merely a static scanner signal.

Evidence

package.jsonscripts/postinstall-patch-pi-ai.mjsscripts/postinstall-bundled-plugins.mjsnode_modules/@mariozechner/pi-ai/dist/providers/openai-completions.jsnode_modules/@mariozechner/pi-ai/dist/providers/openai-responses-shared.js~/.openclaw/plugin-runtime-deps

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

Evidence for block

Installation automatically runs two package scripts.
The postinstall script walks parent directories to locate a hoisted foreign AI dependency.
It replaces code in that dependency and writes the modified source during install.
Another postinstall path deletes legacy state under the user's OpenClaw home directories.
The package name differs from the OpenClaw repository and command identity used throughout its install code.

Evidence against

The inspected install scripts contain no network request or credential collection code.
The dependency patch is limited to cost handling and skips when its expected source shape is absent.
