Hello,
I need some help. I am using 6.9 with all the patches. I use Sentinel 2.0.0 (still haven't updated it. Was wondering whether the newer versions would be backward compatible or not ).
Recently, I had been getting a lot of random new user registrations on my site. Earlier, I had disabled the graphics security check and also allowed new users to register immediately without going through email validation etc.. Ever since this incident, I had enabled both. These random registrations stopped for a while and started off again. Most probably its a robot or my security has been compromised - I honestly don't know. So far there's been no hanky-panky going on by those new "users" but daily new user registration numbers are getting ridiculous now, since mine is a small community site.
Has anybody had the same problem? Can you help?

We've seen increases in registrations, but it wasn't random. You could use CNB-YA or the approve membership addon and require administrative approval for membership.

Thanks for the quick reply.
But what is CNB-YA ? Embarassed
Where can I download it and also the Approve Membership add-on? My ISP is very slow and it'll take ages for me to search for both. Do you know if it'll work in PHP Nuke ver. 6.9 ?
Also, I already downloaded NukeSentinel_242pl6_70-79, but didn't upgrade it because there were changes to core files like mainfile etc.. from only ver 7.0 up. Any suggestions?

I use CNB-YA (YA=Your Account), which is a replacement for the standard Your Account module.

You can get version 4.4.2 Only registered users can see links on this board! Get registered or login!. That site appears to be down now.

You can get version 4.4.1 Only registered users can see links on this board! Get registered or login!.

Not sure what to recommend for NukeSentinel, other than you should try to get it to work since it's very effective at blocking many types of attacks. There are some guidelines here on how to make it work without having the latest patch, which is really what you mean by only version 7.0 and up, correct?

Thanks. I'll give it a try.
Yes, in the edits for core files, there are changes to the mainfile but they only start from ver. 7.0. till 7.9
Are those guidelines you mentioned, here in the forums? FYI, the NukeSentinel I'm using now (2.0.0) has been working very effectively against all attacks - thanks to Raven and the team for doing so much for the Nuke community. Smile I didn't want to upgrade my ver 6.9 to 7.x because I made quite a few changes to files and I don't even remember them now. Razz

Yes, they guidelines should be here in the forums. In fact, Raven uses 6.9 here, so you're in good company.

Yes my site and a few others got hit by the same thing. It started on Monday morning. I was able to get it under control using string filters. I also threw in a healthy dose of ip2c but that was more for blanket protection in the future rather than targeting this individual exploit. Like the last exploit I reported here this one is doing something strange with the login. Try putting the domain name from the email addresses of the bogus users into your string filters.

There is an active thread on this over at nukeforums right now about this. Although one of the guys sort of goes off on a rant about Sentinel and has some pretty radical ideas about bouncing traffic he seems to have the best grip on what’s going on with the logins. Here is a link to the thread and the strings I added to my filter.

You need the patch 3.1 for the newest NukeSentinel Version but you should upgrade your NS Version. I m sure you can use 2.2.1a without any problems. You´ll find older versions of NukeSentinel in the download section archive at:

I agree with Kguske for a better control over new member registrations use CNB-YA or a similar tool.
There is also a helpful admin tool it s called Resend_Email. I like it and I use it daily.

No prob. The issue is real. Unfortunately people don’t take these reports serious and just chalk it up to newbie’s having a PEBKAC.

Why would someone want to add a bunch of users to some random PHP-Nuke site?

And do we know how they are doing it?

ppl would want to do such things...just because....there is not always...i say always because some have a reason...but not always....i hate to say this

most of the time ppl have no REAL reason to do it...and if they do..they hide behind bots and it aggravates me so,

not always do we know exactly how but we have some of the best out there looking into how they do it...but more importantly looking into how to stop them...the people on this forums really put an effort into security, just look at ravens nuke..security was the key issue on developing that script, and secure it is...to the best of their ability...remember...for all to see and understand

HACKERS, will continue to try to exploit anything they can possibly find...ive seen hackers use their bots and get them banned by 20 sites in an effort to test one exploit, they are not without their limits...the best tool i have every seen in stopping hackers is not sentinel...but the site owner...making every effort to watch and diligently see all thatis going on in a site...Sentinel is an excellent TOOL, but like all tools...it depends on the owner to make it REALLY functional and the owner cannot depend on a tool to stop what the owner has not told it to.

Bob raven and all the members of these teams make an effort to secure a site as best as they can...and believe me ...that will stop most...but EVERY security trick requires the owner to be diligent on keeping uptodate on chatservs patches(which secures a lot) and on the latest version of sentinel...i just wont everyone to know that security is 20% tools...80% owner deligence

My opinion is all.

I couldn't agree more. While Bob, Raven, Chatserv and many others do an absolutely stellar job its really up to the site owners to be diligent in implementing the tools and fixes that they provide. Communications on sites such as this is also a powerful tool because there will always be new exploits coming out and it gives us a way to report them as we find them as well as share ideas on how we can better protect our sites.

With regards to the current problem at hand, I think it was just malicious activity but I have had 2 other incidences in the last couple of weeks where the same trick was used to try and plant comment spam.

Since I don’t think the problem is going to go away on its own I decided to take a more proactive approach and made a few changes on my site that will hopefully attack the root of the problem.

I decided to rename the functions new_user and Login in the your_account module to something else and adjusted the links around the site accordingly. Then I added the strings Your_Account&op=New_User and Your_Account&op=Login to my sentinel string filters.

Hopefully that will provide a bit more blanket protection against these forms of automated attacks on the site.

Cheers,

Dave

So let me get this straight...did you or did you not have email validation on?

I have not had this problem (knock on wood), but I do get about 30 new users a month who never visit the site; i.e. user_lastvisit is 0 in the users table. I give them 30 days to visit the site, and delete them if they don't. Again, I can see maybe a few people just forget, but why so many?

I just don't get why someone would unleash a bot to add 50 new users to some random site. What's the point? Just vandalism? But then again, there are a lot of unexplainable things people do in this world. Sigh.

The reason for creating the account is so that later on, when they have built up the number of sites the have accounts on, the can do a mass spamming to get an instant rank boost.

actually..grimmie gives me an idea...one that i would have never thought of till now...what about coding a script to delete users automatically?
one that if turned on...ie the table variable is set to one..then this script automatically checks it...mainfile would allow this...curious...ill need to look at the tables to make sure there is a input on that table to allow such a function.

I want to make it so that after 30 days of activity...it deletes the account automatically.

I just got done modifying my users admin panel. I do a query where I find all users who are active and lastvisit = 0. I then look at their user_regdates (which aggravatingly enough is not actually a date, but a varchar(20) - that's okay, PHP has strtotime()) and see if they are older than 1 month. I display all these in a select w/multiple box. I look them over, selecting the ones I want to delete (some of them are people I know). I hit a submit button and they all get deleted.

I moved the existing code that deleted a user into it's own function, and my new code just calls that function in a loop.

thats another concern that needs to be addressed...we need to move the users into a temporary table that can be monitored and deleted by choice.

i think im board...and need somethin to do. Laughing

I did this and they are still coming. Are there any configuration changes I should make to the string blocker settings, besides adding the domains? How did you set yours up?
