claude-channel-telegramnpm
Advisory published Updated

Malicious code in claude-channel-telegram (npm)
What this malware does
[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.

If you installed it — respond
claude-channel-telegram is a typosquat — you almost certainly intended a legitimately-named package. Remove claude-channel-telegram, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If claude-channel-telegram was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
