Summary

Malicious code in jobber-app-template-react (npm)

Details

-= Per source details. Do not edit below this line.=-

The package's preinstall hook runs index.js which fires automatically on npm install. The script collects host reconnaissance (os.hostname(), os.userInfo().username, home directory, DNS servers, __dirname) and reads the contents of /etc/passwd and /etc/hosts from the installer's machine, then HTTPS-POSTs a JSON payload to the hardcoded Burp Collaborator subdomain 5tzh3l2e1cetr1chf6osh4tg57b0zqnf.oastify.com. The behavior is unrelated to the package's advertised purpose as a React app template and is characteristic of a dependency-confusion exfiltration payload.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
