🛡️ MAL-2026-6255 — fork-angular-daterangepicker

Malicious code in fork-angular-daterangepicker (npm)

Source: amazon-inspector

package.json declares a preinstall lifecycle hook ("preinstall": "node index.js") that runs index.js on every npm install. index.js line 3 hardcodes https://d8s1eti9io6kqja3sg5gsyqs4aqawhqxg.oast.live/npm-installed and issues an HTTPS GET to that endpoint at install time. oast.live is an Interactsh / OAST collaborator service; the unique per-subdomain identifier lets whoever generated it confirm — out-of-band — which hosts installed the package, capturing the installer's source IP, DNS resolver, and install timestamp. The package self-describes as a "PoC package for dependency confusion testing" and its name impersonates the legitimate angular-daterangepicker package, indicating the beacon's purpose is to verify dependency-confusion hits inside private/internal build environments. Even when framed as a "PoC", running this on a real installer leaks network-position metadata to a third party without consent.
