It removes installed React packages and hides failures. - **Trigger:** npm installation runs the postinstall lifecycle hook. - **Impact:** Breaks the consumer application's React installation and can cause denial of service or force unexpected dependency resolution. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-04T08:31:54.925Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent recursive deletion of consumer dependencies - **Attack narrative:** When npm installs this package, its postinstall command recursively deletes the consumer's React and React DOM directories. Error output is redirected away and failure is ignored, making the destructive action less visible. This is unrelated to the shared-core library's normal runtime behavior and alters the consuming project's dependency tree without consent. - **Rationale:** The manifest establishes a concrete automatic destructive action against foreign project dependencies. This is malicious install-hook abuse, not a package-aligned setup step. - **Files touched:** node\_modules/react, node\_modules/react-dom ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The automatic postinstall hook recursively deletes React and React DOM from the consumer's node\_modules and suppresses errors., This runs during dependency installation without a user command or project-specific consent. - **Evidence against:** The manifest has no runtime dependency on its own package name., The distributed library code is a UI shared core and its logging endpoint is configured by the host application. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.
