AI Security Review

scanned 1d ago · by lpm-firewall-ai

The manifest activates a postinstall hook that automatically deletes qualifying older DocNexus workspace data without migration or an affirmative user action. This is concrete install-time destructive behavior, so the package should be blocked.

Static reason

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

Trigger

A local npm installation where the postinstall hook resolves a consuming project containing a qualifying legacy workspace.

Impact

Existing project memory and other contents in the legacy workspace can be lost during installation.

Mechanism

The hook calls cleanupLegacyProject, which identifies older marked DocNexus directories and removes the workspace recursively.

Attack narrative

During local installation, the postinstall hook resolves the consuming project and runs legacy cleanup. When it finds an older marked DocNexus workspace, cleanup recursively removes that directory without migrating its contents. This can destroy project data as a side effect of installing the package.

Decision evidence

public snapshot

AI called this Malicious at 91.0% confidence as Malware with low false-positive risk.

Evidence for block

package.json runs scripts/postinstall.mjs on install.
The hook invokes legacy cleanup for local installations and resolves the consuming project root.
Cleanup selects older DocNexus workspaces using their format marker, then recursively deletes selected directories.
The workspace directory is named docnexus; cleanup does not migrate its contents before removal.
