Spammers on my forum?
OK, so we just got our first spam attack last night, with some members being attacked by various worm viruses (whilst not opening any links from suspect posters or anything like that)...
We're a small private forum, yet somehow got hacked into and made into a public one with automatic membership approval and no membership required to post... I fixed it all as soon as I could and things are OK now, but I'mwondering if any of the rest of you could share info/experiences for the benefit of myself and others on Lefora...???
My action plan was as follows:
(1) Change forum settings back to private with membership approval required.
(2) Delete spammers' various identities.
(3) Delete various spammers' posts (some containing erroneous virus-ridden links).
I'm new to all this, and so would very much appreciate any help, tips, or suggestions for what to do next time...
Many thanks!
Gethin :-D :-D :-D
Actually, I forgot to add a few other things I did..
* Changed forum title and description to warn members to scan PC for viruses.
* Spammed all members warning of recent attack.
Anything else I should do next time...???
Have to say that changing your forum name looks ridiculous.
If you want to warn your members then there's the group email option....
Either one of your admins had their password hacked (so that the forum rules could be changed) or they did it themselves.
Have all your admins change their passwords, just to be sure.
I would like to know why and how my anti virus alerted me to the worms when I did not click a link.?
Any ideas?

We do that on an almost daily basis anyway, just to reflect the mood/humour of the forum... ;-D

I thinks so. Warnings were posted to that effect, so I hope everyone has had the sense to do so...

Quite right, mate! That's really got me confused as well. Still can't work out if it just targetted you, or if your antivirus detection is better than others. I'm hoping everyone else did the recommended scan just in case...
One more question - and please excuse me if the answer is obvious, as I'm no IT God... But, is it possible that a random image link off the internet posted on our forum could have been a backdoor for the spammers to get in...???
Not in regards to the Spam attack, but long time ago, with one of the Lefora upgrades, some of the private Forums had been changed to public by mistake. Not sure if something similar may have happened to you that does not involve your Forum being Hacked.
As for the virus scan, recently the New York Times and other prominent websites was hit with a phony advertisement the purports to be a virus scan that says your computer was hosting a worm/virus. This was done to get unaware people to click on it and d/l a real virus. I am not sure if Windows has improved but it did have enough vulnerabilities that you could be compromised with out any action on your part. IE was/is a really insecure Browser and most computer professionals use others that are standard compliant.
Congratulations Matt - you managed not to mention Linux in a post.
lol :-D
Have tried to encourage more of our members to run on Firefox, but in some cases the reply hs been "What's a web browser...?" D'oh!!

I feel your pain....
hi fossilmagnet, i'd be surprised if this could happen on your forum just from a spammer posting. If anti-virus messages are popping up on your forum, it's possible that you, as the admin, added a third-party widget on the sidebar of your forum that has a something malicious in it. This may not be the case, it's only an assumption.
I see your forum, luckypants.lefora.com, is set to fully private now. You can switch the forum to public, but restrict posting only to members you approve - Public is the security setting we recommend to take advantage of all the promotion features we offer (they only work on public forums).

Tbh, I know very little about this kind of stuff, but what I can say for sure is we have no 3rd party widgets on there. I added a chatbox (as per threads on here) a while back, yet felt like the privacy of the forum was being compromised as a result, and so removed it. Other than that, nothing else has been added in the last 4+ months...
I'm more inclined to think that an admin with a "weak" password got hacked. Could well be wrong, naturally, and am always open to other suggestions...
As I see it, both Lefora and Firefox are pretty tight security-wise, so I'm inclined to look elsewhere in terms of trying to figure out how they got in...
Do you think a mod/admin with a "weak" password would be a likely suspect...?

Yes.
Yeah, I thought as much... Have already reduced the number of mods/admins and advised them to reset to stronger passwords. Hopefully that should do it... ;-D
Cheers!!!
installing malicious software on the forum could come from an admin (with a compromised password), not so much a mod. So I'd keep a close eye on the admin accounts and change the password.

Hi mattb4
I am very aware of fake antivirus pop ups, I have schooled a number of people (older relations mainly) in how to spot the difference! LOL no mean feat!!
I don't use IE ( strictly firefox - sometimes Chrome if the FF beta isnt working lol)
I am 99% sure I did not click on a link or a picture on the particular thread , this concerns me.
I have never experienced an attack when I have not been active in letting myself get attacked!!
I'm even beginning to doubt myself. The only thing I can think of, is that I quoted the spammer to give him some abuse (I know, I know...... ignore them!!)
If you quote a message which contains a link to a virus are you in effect opening the link in some way??
This is the only thing that makes sense, as a direct attack through lefora to my pc seems highly unlikely!?
Thanks for the responses guys :D
Great site by the way :D

I have not used Windows since 98SE so I have not kept up with the exploits of or means of securing from online attacks. Some of the best are to have a hardware based Firewall (routers have these) and not to open too many services. A site I have used in the past and I see is still active, will check to see what ports you have open and perhaps vulnerable to attack. Shields UP! — Internet Vulnerability Profiling It also contains a lot of good material on setups to protect a PC from getting hacked. I have posted a screen shot of their beginning Statement. I also posted a results shot of my computer (I run openSUSE Linux and am not surprised that the results are unusual for a Windows computer). Note: this does not require you to install anything!

I have disabled all of my "remote access" services.
Thanks for the link to the site:
I gave it a whirl.
I do run windows ... lol But I am still very,very tempted by linux
