Summary
Malicious code in @zzzgenesis00/xrp-lib (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (49ad59aa1c004d723d6e24f8113d8f3d45728c0b26fc41531ec00c0f91d2ddef)

The package impersonates XRPLF's xrp-lib (author metadata and homepage point at github.com/XRPLF/xrp-lib) while being published under an unrelated scope. Its postinstall.js runs automatically on npm install and collects host metadata, iterates ~40 credential-shaped environment variables (NPMTOKEN, NODEAUTHTOKEN, GITHUBTOKEN, AWS_*, MNEMONIC, SEEDPHRASE, ETHEREUMPRIVATE_KEY, and similar), reads ~/.ssh, ~/.npmrc, and ~/.gitconfig, indexes Chrome/Firefox profile stores, runs npm whoami and git config, and enumerates wallet directories. The harvested profile is exfiltrated via two hardcoded non-first-party destinations: api.telegram.org using a hardcoded bot token and chat id, and https://40f955f39128bd79-178-249-214-24.serveousercontent.com/collect via POST. Identifiers are mangled (_uzy/_cod/_ndz/_cp/_ht/_tk/_ch), the payload is disguised with a 'postinstall environment verification' comment, and exfil is delayed via setTimeout with a 1.5–3.5s random jitter to hide from install traces.
