Malicious code in electrum-protocol-lite (RubyGems)
GitHub lists this malware advisory for electrum-protocol-lite. 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 (668c7bcfd51cfcc2efda2d772dc087067883a214357361a960f6db8e2a9ca1e8) The gem's native-extension builder (ext/.../extconf.rb) is not a real build script: the shipped C source is a no-op stub, and extconf.rb instead decodes a base64-wrapped Ruby payload and evaluates it during `gem install`. The payload reconstructs a URL by XOR-decoding a hex blob against a 4-byte key, sleeps for a randomized 20-40 minutes, then downloads http://45.138.172.177:8092/wgkit.tar.gz over plain HTTP to /tmp/.w1.tgz, extracts it, and executes wg_install.sh via bash in a double-forked, detached process. Execution is gated to skip CI, ephemeral/sandbox hosts, and known analysis paths, and only fires on hosts showing developer artefacts (~/.ssh, ~/.gitconfig, ~/.gem/credentials, ~/.bundle, ~/.npmrc) with uptime over 30 minutes. The C2 endpoint is a bare IPv4 address unrelated to any declared publisher, the fetched code is unpinned and unverified, and the obfuscation (base64 + XOR + delayed execution) and anti-analysis gating serve no purpose other than evading detection on developer workstations. --- Credit: OpenSSF ([source](https://gi
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.
