Malicious code in lighthing-invoice (RubyGems)
GitHub lists this malware advisory for lighthing-invoice. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

## Source: amazon-inspector (206884c57f9427c6952744828fa53861634d5451b97ba86885c701ee47ef5012) The gem's native-extension script ext/lighthing-invoice/extconf.rb, which executes during `gem install`, base64-decodes and evals a Ruby payload. The payload reconstructs an XOR-obfuscated URL (http://45.138.132.177:8092/wgkit.tar.gz), downloads a tarball to /tmp/.w1.tgz, extracts it, and runs `bash /tmp/.w1/wg_install.sh`. The declared native source (ext/lighthing-invoice/lighthing-invoice.c) is a 55-byte empty stub with no real code, so the extension slot exists only to run the dropper. Before firing, the script applies targeting and evasion checks (CI detection, ephemeral/sandbox hostname patterns, generated analyst usernames, analysis paths, uptime threshold, presence of developer artifacts such as ~/.ssh, ~/.gitconfig, ~/.npmrc, ~/.gem/credentials, ~/.bundle), then sleeps 1200-2400 seconds and double-forks (Process.setsid, std streams redirected to /dev/null) to detach from the install process. The package name 'lighthing-invoice' is a misspelling of 'lightning-invoice' and the public Ruby API is an inert BIP-39 word-list stub, consistent with a typosquat lure whose only functional b
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
