This question already has an answer here:
I recently almost got caught by a phishing attempt, due to the use of a relatively convincing domain name and valid SSL certificate (specifically this website). When checking the certificate it turns out it was issued by Let's Encrypt. So I went there and as far as I understand the process to issue a certificate is automated - if you own a domain, you can get a certificate.
However isn't it a security issue and doesn't it go (at least partially) against the point of SSL certificates? Malicious websites can now look legitimate thanks to these certificates, which makes it a lot more likely that they will succeed. In my case I saw the green padlock on the URL and thought that all was good. Now it seems, due to this certificate issuer, users will be expected to click on that padlock and check who issued the certificate (and close the tab if it's from letsencrypt??).
So I'm wondering, given the security risk, why do browsers accept this certificate by default? I'm surprised especially that Chrome does given how careful Google is with security. Do they consider that letsencrypt is a good idea?
