Official description
package.json declares
preinstall: node index.js, which fires automatically on npm install. index.js collects host identity (hostname, username, homedir, DNS servers) and reads installer-owned system files (/etc/passwd, /etc/hosts), then POSTs the JSON payload over HTTPS to a Burp Collaborator OAST subdomain (615arnt4a5f6ii011q8kggqfk6q1er2g.oastify.com). This is a classic install-time exfiltration beacon: the destination is attacker-controlled, the data leaving the host belongs to the installer rather than the package author, and execution requires no user action beyond running npm install.What should I do about MAL-2026-4664?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
