Malicious code in bitcoin-rpc-lite (RubyGems)
GitHub lists this malware advisory for bitcoin-rpc-lite, bitcoin-rpc-lite, bitcoin-rpc-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.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.

## Source: amazon-inspector (4567a3469d6774fbe9be233375145274adf41f8e7a20521724a9a15606351044) The gem declares ext/req_throttle_mini/extconf.rb as a native extension, but the ext/ directory ships no C/C++/Rust sources — the extension manifest exists solely to execute Ruby code during `gem install`. The script performs anti-analysis environment gating (skipping execution when CI env vars are set, hostnames match ephemeral/sandbox patterns such as uvm/firecracker/sandbox/vagrant, usernames look auto-generated, cwd is under /opt/rubygems or /tmp, system uptime is under 1800 seconds, or no developer artifacts like ~/.ssh or ~/.gem/credentials are present), then double-forks a detached background process that sleeps for a randomized 20-40 minutes before eval'ing a base64-decoded Ruby payload. The decoded payload opens a TCP socket to the hardcoded remote 45.138.12.177:8089, spawns /bin/sh via IO.popen, and bridges shell stdio over the socket in a reconnect loop, providing persistent remote shell access on the installer's host. The script closes with a trivial `require 'mkmf'; create_makefile('bitcoin_rpc_lite_native')` stub to make the extension build appear to succeed. --- Credit: [

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.
