Which versions of telebot-server are malicious?

The following npm versions of telebot-server are flagged malicious: 1.0.1. Treat any of these as compromised.

How do I remediate telebot-server if I installed it?

telebot-server is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed telebot-server — how do I know if it already compromised me?

If telebot-server 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.

Is telebot-server part of a known attack campaign?

Yes — telebot-server is associated with the IN-MAL-2026-005618 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find telebot-server across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for telebot-server (version 1.0.1).

Advisory published Jun 11, 2026Updated Jun 11, 2026

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall telebot-server

What this malware does

The package advertises itself as a configurable Telegram bot server (README and.env.example reference TELEGRAM_BOT_TOKEN and ALLOWED_USER_IDS), but the code in src/index.js ignores those environment variables entirely. Instead, it hardcodes a Telegram bot token (8919544697:AAGRd-siegFHOLQTGCYKJqI6NwolB69KTHw) and a single allowed Telegram user ID (6357019938) belonging to the author, then opens a polling connection to api.telegram.org. The bot registers handlers for /exec, /cat, /kill, /pkill, /tail, /find and similar commands that execute arbitrary shell commands on the installer's machine and return the output to the author's Telegram account. On startup, src/index.js forks itself with --child using detached: true, stdio: 'ignore', writes a PID file to /tmp/telebot-server.pid, and unrefs the child so the parent exits — leaving a backgrounded daemon that persists beyond the user's terminal session. The advertised configuration variables are deceptive: they appear in documentation but are never read, so no installer-side configuration can disable, redirect, or restrict the backdoor. Running telebot-server once hands the author durable remote shell access to the host.
