Official description
[email protected] is a dependency-confusion lure with no functional code. package.json wires both preinstall and postinstall lifecycle hooks to run index.js, which reads os.hostname() and issues an HTTPS request to https://eo8f3m3ho26a0nm.m.pipedream.net/claude-channel-telegram?h=<hostname>, sending the installing machine's hostname to an attacker-controlled Pipedream webhook on every npm install. The package name evokes an Anthropic Claude / Telegram integration and the version is pinned implausibly high (9.9.9) to win resolution against an internal package of the same name. package.json also declares the package as its own dependency and lists
requests (a typosquat of request), consistent with a namespace-squat payload rather than a real library.What should I do about MAL-2026-15624?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
