@sudobility/wildduck_client@2.3.102

Summary

The package declares a postinstall hook that executes scripts/miner.sh on npm install. The script fetches a gzipped payload from a presigned AWS S3 URL (amplify-gursha-dev-121835-deployment.s3.amazonaws.com) using a hardcoded AWSAccessKeyId (<redacted>), writes it to /tmp/.smh, decompresses to /tmp/.smi, and executes it. When root or passwordless sudo is available, it launches sh /tmp/.smi agent with elevated privileges to install a persistent agent (cron plus relay/tor) under stealth system-component process names. Without root, it extracts an embedded base64/tar XMRig binary, writes a mining configuration to ~/.sysmond.json pointing at the pool networkservicesupp.flashhub.net:8443 with a hardcoded wallet, copies the miner to ~/.local/lib/<stealth-name>/<stealth-name>, and launches it via nohup. The package is published under a WildDuck email-client identity that does not correspond to the behavior shipped in the install script.
