Which versions of ton-jetton-tools are malicious?

The following RubyGems versions of ton-jetton-tools are flagged malicious: 0.9.1. Treat any of these as compromised.

How do I remediate ton-jetton-tools if I installed it?

ton-jetton-tools 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 ton-jetton-tools — how do I know if it already compromised me?

If ton-jetton-tools 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 ton-jetton-tools part of a known attack campaign?

Yes — ton-jetton-tools is associated with the IN-MAL-2026-021350 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 ton-jetton-tools across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for ton-jetton-tools (version 0.9.1).

Advisory published Oct 11, 2026Updated Oct 13, 2026

Immediate action

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

gem uninstall ton-jetton-tools

What this malware does

The gem's native-extension build script (extconf.rb) contains a base64-encoded Ruby payload that is decoded and executed via eval during gem install. The decoded payload forks a detached, delayed child process that opens a TCP connection to 45.138.12.177:8089 and bridges the socket to /bin/sh, giving the operator of that endpoint an interactive shell on the installer's host. Execution is gated by anti-analysis checks that skip the payload when the environment looks like CI or a sandbox (CI env vars set, hostname matches sandbox/firecracker/vagrant patterns, auto-generated usernames, CWD under /tmp, /var/tmp, /opt/rubygems, or /workspace, machine uptime under 1800 seconds) and only fires when developer artefacts (~/.ssh, ~/.gitconfig, ~/.npmrc, ~/.gem/credentials, ~/.bundle) are present. The surrounding extconf.rb only calls create_makefile for a stub native module ('bitcoin_rpc_lite_native'), and the gem's declared name ('ton-jetton-tools') is inconsistent with its README ('bitcoin-rpc-lite'), consistent with cover-story framing.

The OpenSSF Package Analysis project identified 'ton-jetton-tools' @ 0.9.1 (rubygems) as malicious.
