Official description
On
npm install, package.json's preinstall hook runs index.js, which collects host identifiers (os.hostname(), os.userInfo(), homedir, DNS servers, __dirname, the package's own package.json) and reads the contents of /etc/passwd and /etc/hosts, then HTTPS-POSTs the resulting JSON to a Burp Collaborator subdomain at 3z3l99x7vp8us6lzqm575hfh58bzzqnf.oastify.com. The package has no documented purpose and no library functionality — its only effect on installers is the exfiltration beacon. Any developer or CI system that runs npm install ppt-creator leaks user-account enumeration data and host fingerprints to the attacker-controlled collaborator endpoint.What should I do about MAL-2026-6355?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
