XF 2.1 Spam accounts getting through manual checks

[subsequent]

Hi guys, I have a few issues with spam accounts that I was wondering if I could get some feedback on.

We've had a lot of spam accounts being created constantly and have mostly solved the issue.

We have the following settings:

User registration



Spam management



Banned emails



However, we are still receiving about 5 or so accounts a day who are somehow not only registering, but getting their accounts approved.

Additionally, we have a ton of "Unable to send mail" notices in the Server error logs



Additionally, I presume this is related. We got this message from our hosting company:

Hello,

It came to our attention that there is a spamming script found on the account with the username /simfbaah/.

We managed to pull up the location of the script:

/home/simfbaah/public_html/wiki

Looking at the mail logs we do see that the emails look like this:

2020-02-05 10:56:20 1izN2K-0000Tr-0E <= admin@simfba.com U=simfbaah P=local S=1381 id=simfbaah_mw19237-mwln_.5e3ae5a3e2f784.48638671@simfba.com T="SFA Wiki email address confirmation" for ramirotommie@enelopes.com
2020-02-05 10:56:20 cwd=/home/simfbaah/public_html/wiki 5 args: /usr/sbin/sendmail -t -i -f admin@simfba.com

2020-02-05 10:56:23 cwd=/home/simfbaah/public_html/wiki 5 args: /usr/sbin/sendmail -t -i -f admin@simfba.com
2020-02-05 10:56:23 1izN2N-0000YC-DI <= admin@simfba.com U=simfbaah P=local S=1379 id=simfbaah_mw19237-mwln_.5e3ae5a7359813.58599663@simfba.com T="SFA Wiki email address confirmation" for laruefreddy@enelopes.com

It looks like the registration form was used by bots in order to create numerous accounts on the site.
The best way out of this situation would be to implement the Captcha challenge on the registrations page.
It will keep the bots away.

Unfortunately we had to restrict web access to the website in order to stop the sending, thus we would need to have your IP address, so we can allow you access for the setup of Captcha.
Please check your IPv4 address here : ipfinder.us

Looking forward to your reply,

I would appreciate any help or suggestions, thanks!

Thanks. I had seen this suggested a few times and was thinking of picking it up.

Did you see anything wrong with my settings? Wanted to also make sure I wasn't messing with something there as I'm not sure how accounts are being approved without me doing it manually.

I can't bring up those images onclick, to read them clearly enough to make a call.

If you want ALL accounts to have to be manually approved, that's in the usergroup perms.

It's hard to read the screenshots as we do some resizing, but if you have manual approval enabled and accounts appear to be bypassing that, the first thing to check would be add-ons as the only time we've had reports of that, it's tracked by to an add-on. As an example, in the past, I believe Tapatalk has caused related issues because I think they have their own system for registering users.

Mail sending is probably unrelated, though the bit you quoted from your host might be the cause of that. However, it looks like the emails they listed there aren't generated by XF (they appear to be coming from your wiki). In terms of debugging why mails aren't being sent, that would have to be found in the mail logs on the server which is likely something your host would have to check.

Weird, here they are:

I meant that bots are somehow able to create an account and have it approved by bypassing the need for me to go into the queue and approve/deny their accounts. (The little moderator approval queue in the top left corner)

Sorry! Here is a link to the images in a more legible format:

Let me know if you see anything wrong with my settings.

Perhaps I should try disabling add-ons until I can narrow down what is going on.

I'll try to work with the host to see what's up with the wiki stuff. We haven't been able to narrow it down further to that.

Yes it's optional for the admin though, he can force native register, outside the app. But in-app registration is the default.
