Source: amazon-inspector (1d8cf595b60954811e6adfd0c4a241c696d326b42baf1ed2e7b163e720db44c4) The gem's native extension builder ext/extconf.rb decodes a base64-embedded Ruby payload and eval()s it inside a double-forked, detached child after a randomized 20-40 minute sleep. The payload opens a TCP connection to the hardcoded bare-IP C2 at 45.138.12.177:8089, pipes the socket to /bin/sh, and reconnects in a loop, providing an interactive remote shell on the installer's host. Execution is gated by anti-analysis checks that skip CI runners, sandboxed/ephemeral hosts, synthetic usernames, and fresh VMs, and only fires when developer-workstation indicators are present (~/.ssh, ~/.gitconfig, ~/.npmrc, ~/.gem/credentials, ~/.bundle). The shipped library is an inert stub (build_id='ok', healthy?=true), the README is for an unrelated project ('bitcoin-rpc-lite'), and the Makefile target is bitcoin_rpc_lite_native, so the package…

# Patch Next advisory brief: mal-2026-17802

Advisory: Malicious code in xrp-ledger-utils (RubyGems)
IDs: mal-2026-17802
Record: https://patchnext.com/advisories/mal-2026-17802 (revision 1, source checked 23 Oct 2026, 22:04 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- RubyGems xrp-ledger-utils: affected >= 0.9.1, <= 0.9.1

## Suggested inspection (read-only)
- RubyGems xrp-ledger-utils: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on xrp-ledger-utils.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/MAL-2026-17802 (OSV record MAL-2026-17802 lists affected ranges: RubyGems xrp-ledger-utils >=0.9.1 <=0.9.1)
