27 malicious npm packages were discovered in a phishing campaign targeting U.S. and allied organizations, primarily in sales and commercial sectors. The campaign utilized these packages to host phishing infrastructure, mimicking document-sharing portals and Microsoft sign-in pages, to steal login credentials from their targets. Attackers embedded client-side scripts to avoid detection and included checks to filter out bots. Notably, the campaign hard-coded specific email addresses of individuals in targeted firms, raising concerns about the source of this information. To mitigate risks, strong dependency verification, logging unusual CDN requests, enforcing phishing-resistant multi-factor authentication, and monitoring for suspicious activities are recommended.
