The fact this is NOT the standard phishing email shows how low the bar is:
1. the text of the email reads like one you'd get from npm in the tone, format and lack of obvious spelling & grammatical errors. It pushes you to move quicker than you might normally, without triggering the typical suspicions.
2. the landing domain and website copy seem really close to legit, no obfuscated massive subdomain, no uncanny login screen, etc.
All the talk of AI disrupting tech; this is an angle where generative AI can have a massive impact in democratizing the global phishing industry. I do agree with you that there's likely many more authors who have been tricked and we haven't seen the full fallout.
