Being logged out by bots trying to log in
« on: January 11, 2011, 11:11:02 PM »
There seems to be IS a problem with being logged out by bots trying to log in with various user names.
This seems to be a unique SMF problem......any plans on blocking them as I have SEVERAL IP's blocked, and new ones try every day!
 
What is going to be done about it?
 
 
I have these blocked so far with .htacces, but getting tired of adding IP's every day!!!!!!

how are spambots and spamtards a unique smf problem?
Please do not PM, IM or Email me with support questions.  You will get better and faster responses in the support boards.  Thank you.

I think their specific problem is that login attempts against existing usernames are somehow causing existing user sessions to expire.

I believe this happens at the point where a bot reaches the limit for failed logins - I've seen this issue raised a couple of times now, never seen it myself though.

I just raised the Failed login threshold so maybe we won't be logged out before I can IP block the bots, BUT I wish something can be done to stop this.

I'm seeing it every day but it only happens to each user for about 24 hours. If it's happening to a user that doesn't log in much you don't hear about it but if it's a regular user it annoying as heck.

I went into Configuration/Security and Moderation and raised the Failed login threshold to 99 so members wont be logged out, and I go to maintenance and check the error log (filter user) and ban all bots that don't have a regular member IP.
 
I add them to a .htacces in the root of my domain....they never make it to the forum after that.........BUT I should not have to, they should not be able to get to the member list!
 
Here is my Current .htaccess......I add about 20 IP's a day!

Here is my Current .htaccess......I add about 20 IP's a day!

You should consolidate and use subnets where possible. The WHOIS command is great for looking up allocations for blocks.

If you have server access, use iptables (Linux) or pf (BSD) to block the IPs at the system level.

Unless you need to, disable memberlist access for guests. You can't block member names in posts without blocking all guests, however.

You could see if you can add a referrer check to the login process to avoid direct submissions. Note that this will break logins for a very small percentage of users that block sending referrers or who use networks that do so.

I would love to, I have 2.0 RC3.....How would I do that?

If you are using Linux or OS X as your desktop system, open up a terminal and simply run "whois ip address". If you're on Windows, you will probably want to download JWhois from GNUWin32, then run that from the command prompt.

Reading WHOIS info on IPs takes some learning, and is a bit more involved than I will get into here. However, I will give an example from on of your above listed IPs.

From the above search, we see that the range that IP falls in is specifically "174.36.199.200 - 174.36.199.207". In SMF, you can add the IP ban as "174.36.199.200-207". Checking with an online subnet calculator, they are likely a /29. (In some notation it would be: 174.36.199.200/29). Some WHOIS servers will kindly provide the subnet mask bits (the number after the /)

Further, the range that service is in is owned by SoftLayer, a server provider. No humans should normally be browsing from that their range, so you can block 174.36.0.0 - 174.37.255.255. That's two /16 blocks, by the way (I am a sysadmin by trade, so I know the basic subnet masks).



If you have server access, use iptables (Linux) or pf (BSD) to block the IPs at the system level.

I do have server access, but you lost me....what do I need to do?

Using the IP ranges I looked up above, you can do the following using iptables.

For the most restrictive set (the /29 network), the following command will work.


iptables -I INPUT -s 174.36.199.200/29 -j DROP


For that whole block for SoftLayer, you'd use:


iptables -I INPUT -s 174.36.0.0/16 -j DROP
iptables -I INPUT -s 174.37.0.0/16 -j DROP


As a bonus with iptables, httpd doesn't even see the requests as they are being blocked before they ever go to it. If you don't want to figure out the mask bits (the number after the /) you can also use full ranges like show in the WHOIS output, just don't use spaces around the hyphen.

You'll need to look up the rules for pf if you're on BSD.

Also note that these will only stay applied until the firewall service is restarted, or a reboot. Different distributions store iptables information in different ways. Check documentation on how to save the rules so they persist.

 
 
Unless you need to, disable memberlist access for guests.

I would love to, I have 2.0 RC3.....How would I do that?

Admin -> Members -> Permissions

Modify the permisions for Guests. Uncheck "View profile summary and stats" and save.

 
 
You could see if you can add a referrer check to the login process to avoid direct submissions. Note that this will break logins for a very small percentage of users that block sending referrers or who use networks that do so.

I have 2.0 RC3.....How would I do that?

That would require code changes and I honestly don't have the time to dig into the code and find the best way to handle it. Honestly, it's a last-choice option, something that you should only do if all other efforts fail as it has the most chance of causing issues for real users.

I'm having the exact same problem with many of those same IPs. Many are TOR proxy IP's so I used a TOR bulk list exporter to block them on .htaccess - https://check.torproject.org/cgi-bin/TorBulkExitList.py

The number of invalid logins have dropped significantly since I did that (as well as members getting logged out) but I am still getting a few attempts every day. I will also try the suggestion here to increase the invalid login threshold to see if that helps. The main problem I was having is that most members online were getting logged out every 3-5 mins.

This issue was really annoying my users - reported in 2.0 Support board.

Best solution for me, to stop them dead, was to switch log-ins to email address rather userID - there is a mod for this called 'force email registration' I think.

I also installed Snoopy's httpBL Project Honeypot mod - follow his excellent instructions, a very worthwhile spambot blocker.

It'll scare you how many of these things are visiting your site every hour!

There seems to be IS a problem with being logged out by bots trying to log in with various user names.
This seems to be a unique SMF problem......any plans on blocking them as I have SEVERAL IP's blocked, and new ones try every day!
 
What is going to be done about it?
 
 
I have these blocked so far with .htacces, but getting tired of adding IP's every day!!!!!!
 
 
Code: [Select]
deny from 62.24.181.134
deny from 62.24.181.135

those IP are related to a stalker bot from Talk Talk, there is a bit of controversy over it following TT users around the net supposedly for an antimalware product TT are supposed to be trialing

it has been breaking a few thing all over the web,

have alook at www. the-phoenix-broadband-advice-community .co. uk/index.php/topic,1828.0. html and https :// nodpi. org/forum/index.php/topic,2991.0. html

sorry both are long threads but have a lot of information in them

the owner of pheonix is taking legal action against talk talk over it

acams,

could you clarify which ip's are the main causes of the logging out issues?

is it all in your HTACCESS list or just some?

thanks

I just installed the httpBL modification recently on two of the boards I manage. It seems to work very well. You might want to try it out.
