SCAM ALERT 📈
https://youtu.be/c46SHaja1l0TL;DR:
Hackers have hacked a lot of Indian government websites, probably for years.
They are using a user-agent hack to make Google rank those pages and only serve GoogleBot those specific pages, normally it's 404-not found
For users, they are checking the referrer header to redirect them to betting website. (ie. if referrer = google)
Anyway, it’s really dangerous. I’m switching to Brave Search since GoogleBot is the most vulnerable.
