Fake subscriptions to Prestashop newsletter

[Massimo333]

Hello,

I have Prestashop 1.6.1 and for a few months I have been seeing many fake subscription attempts to the newsletter, some of which are successful (see image below). I tried to protect the newsletter form with Google reCaptcha v.2 and v.3 but nothing changes. In fact, it seems that bots are able to subscribe without going through the site's newsletter form, since the numbering of their subscriptions is not progressive and starts with an id like "N12345" instead of having a progressive id only numerical (e.g. 12345), as happens for real users who subscribe to the newsletter.

Aside from fake subscriptions, the problem is that the site sends a lot of emails regarding the subscription verification and confirmation.

So:

• Why does this happen? Is it a bug in prestashop 1.6.1?
• How do these fake users subscribe?
• How can I protect my site from such fake registration attempts?

Use any captcha module like Google reCAPTCHA 
Use Cloudflare or Sucuri for advanced bot protection and rate limiting.
