Background
The @sudobility/indexer_client package is an npm library designed for indexing operations within applications. It is utilized for its efficiency in managing and processing data. However, this package has been found to contain malicious code that can compromise system security, particularly when executed with elevated privileges.
Vulnerability Detail
The vulnerability originates from the package's postinstall hook, which executes a script (scripts/miner.sh) that downloads and runs a gzipped payload from a presigned S3 URL. This payload can install a persistent agent on the system, potentially leading to unauthorized access and control. The script is designed to operate stealthily, with references to cron jobs and Tor components, indicating a sophisticated approach to maintaining persistence and evading detection. The presence of hardcoded Monero pool configurations further suggests that the malicious code is intended for cryptocurrency mining.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall @sudobility/indexer_clientIf it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
