If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

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.\n\nThe OpenSSF Package Analysis project identified 'ton-jetton-tools' @ 0.9.1 (rubygems) as malicious.\n\nIt is considered malicious because:\n\n- The package executes one or more commands associated with malicious behavior.","ecosystems":["RubyGems"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in ton-jetton-tools (RubyGems)","id":"MAL-2026-17797","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"RubyGems","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"RubyGems","fixed":[],"introduced":[],"last_affected":[],"package":"ton-jetton-tools","purl":"pkg:gem/ton-jetton-tools","source":"MAL-2026-17797"}],"products":null,"published":"2026-10-11","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-17797/"}
