Anyone Else Seeing WordPress Spammer DDOS
Jan 5, 2007
For about a month or so now I have a domain I host under serious attack from what I think are spammers. It's a wordpress site, and they are getting big numbers of POST requests to the WordPress comments file, e.g.
Code:
POST /wp-comments-post.php HTTP/1.1
It's a well distributed attack, and I'm doing well with some scripts I wrote to block the requests to the wp-comments-post.php file. The real comment file has long since been moved, so any POST to the file gets firewalled. It's several thousand IPs from all over the place.
I don't believe it's a malicious attempt to bring the site down, but I'm guessing it's a blog comment spammer that has something set wrong and he's pounding this site to death by accident. I could be wrong on that though.
Anyone have any good defense scripts to share?

I have recently been receiving reports from AOL's feedback loop that my server is sending out spam. I have checked the whole server, but cannot find anything strange.
There are some strange things with these feedback reports. I'll post a few lines below (i crossed out my domain with xxx):
Quote:
Received: from andersenreesel by holderem.xxx.biz with local (Exim 4.23)
Received: (qmail 64859 invoked by uid 24901)
Received: from janislanhami by xxx.biz with local (Exim 4.26)
Received: (qmail 43829 invoked by uid 147); 08 Apr 2009 21:22:39 -0000
Received: from raphaelpinkertone by standei.xxx.biz with local (Exim 4.23)
Received: from imanoldelphine by dispatched.xxx.biz with local (Exim 4.23)
Received: from conrado by hostic.xxx.biz with local (Exim 4.23)
The first issue i have is with the subdomains, like "dispatched", "standei", "hostic", etc. These subdomains do not exist on my system. Also, my server does not run the exim MTA.
Another issue i have is the "invoked by uid" statements with uid's 147 and 24901. These UID's do not exist on my system. The passwd file uid's go to around 110.
Apart from these strange things, the IP that is listed in the upper part of the headers:
Quote:
Received: from xxx.biz (xxx.biz [85.xxx.xxx.xxx])
The domain and IP address is correct there, which should indicate that the spam was sent from my system. Or wasn't it?

I host a vBulletin forum on a US server. I've been getting a lot of signups from one particular spammer, wanting to post about gold harvesting for WoW. I've blocked his IP's, however he keeps using proxies.
He constantly signs up under the name "Array"... Is there a way I can block him for good? I can't moderate user sign-ups, as I'm mostly away from my computer and can't moderate them all the time.

I just setup my own LAMP server.
It is only used for my own domains so I want to be able to watch all mail that gets sent from my server, via php or otherwise.
Basically I just want to be able to personally monitor what mail is getting sent from my server so that I can watch for possible spammer activity.
I am using postfix and webmin.. I have sendmail installed to, but I don't think it is getting used..
I guess theres got to be a log somwhere... but I am not sure where it is?
I have postfix set to CC me of all mail that gets sent but, it doesnt seem to work all the time.. just for certain things..

I just found posts every a few days from an apparent spammer "sagepowder" in my forum (not so popular and has nothing to do with skiing). The subject is always "new here".
The content is "Any snowboarders or skiiers on this forum? I am planning a trip to BC on a snowboarding trip next week" or "I am new here, just saying hello".
I checked the apache log and it doesn't seem to be a robot script posting this. i.e. it browses to the index page, picked up my hidden field that blocks robots, post new topic, the go back to index page.
What surprised me is that when I google this guy, I got 108,000 results with the same content on tons of forums! All with total post number of 1 or 2 on each forum:

How did he do this? How to block this?

I recently moved web services for one of my hosted domains (let's call it example.com) from one server (let's call it .org) to another server (let's call it .net) example.com has been on .org for about 5 years. .org handled all example.com web services, and all email. I recently updated example.com's DNS record to point www.example.com and example.com to the .net server. I didn't change the MX record or mail.example.com to point to .net. Mail continues to be delivered normally to example.com on the .org server.
Except now spammers are hitting the .net server, e.g.
Sep 26 09:26:03 host postfix/smtpd[15098]: NOQUEUE: reject: RCPT from unknown[12.171.150.130]: 554 5.7.1 <AutumnvagaryMontano@example.com>: Relay access denied; from=<> to=AutumnvagaryMontano@example.com proto=SMTP helo=<mdgen-print.marylandgeneral.org>
Is it normal practice for spammers to send dictionary attack based spam to a domain's server that doesn't even handle email? All the spam coming is clearly just random email addresses not based on anything that exsists at the domain, and most of the addresses are so very random I can't imagine they exsist anywhere.

My System is a Windows Server 2012 r2 with Plesk 12.
On this system i have installed MailEnable as my Mailserver.
So at the moment something is spam on this server, but i can't find out who is it.

[Code].....
The header is meaning that the spams come from root@, but there is no account with the name root@...
On linux it is so easy to find the spam with qmail or postfix. Why mailenable it is so difficult

it's come under my attention that dragonara.net has been ddosing me today since morning from the ip:
194.8.75.229
What's so ironic about it is that the ip is from a UK DDOS protection site so i'm expecting some email with their services in the next hour or so. Stay clear of them they are fakes and e-terrorists.

Just logged in to Spam Karma 2 (for wordpress) and noticed this message inside ht e2nd chance Captcha Check of Spam Karma 2:
Your install of PHP seems to be missing the GD library (or a more recent version is needed). You should ask your host to update the GD module for PHP and disable the Captcha module until then.
Can we get our server management company to install this? More importantly, wanted to know the risk of installing the GD library. It's not going to cause any critical things to break is it?

For some reason, one of my clients wordpress blog is using 100% cpu on a php process per page load. To clarify, the first time you load the page it is very slow, and uses 100% cpu for the PHP process and then if you reload the page (while it is going slow) it loads very fast. After that is done the normal PHP usage per page load is roughly 1-4% if that.
I'm guessing something in the coding is looping, but I am unsure. What I do know is 100% cpu usage for one page view initially is insane.
Does anyone have any ideas on how to fix/resolve this issue?

I don't have Linux or whatever I just got Windows XP or Vista.
I'm not an expert at creating websites, I find it difficult. I don't want to have to install databases or msyql manually, I just don't have a clue and would rather leave it.
I just know how to use WordPress and I want a WordPress hosted site.
I would like to know if there are any sites similiar to this:
[url]
Which includes stuff like cPanel & Fantastico
[url]
Fantastico looks brilliant as I can simply install WordPress in a few clicks without having to mess with FTP and database/msqyl etc.
Does anyone know any reccomended sites that use Fantastico for Windows Vista which I can install WordPress easily?
(I don't want to use '3ix' as I have seen ALOT of negative reviews)

I am using version 2.3.1 on one site which I need to import over to wordpress.com However, a long time go the link to the back up options page disappeared and even upgrading does not help to retrieve it.
My problem being that over at the main site you need a WordPress WXR file to import with from a self hosted site. As mentioned that is not an option and I must have it imported somehow. I cannot also access the plugins page.

I had no problem installing Wordpress Mu with iPower. Unfortunately iPower really sucks for performance (I have paid one full year though so I have to keep them ).
So I have moved to Hostgator but I'm struggling: there are many things that need to be done to be able to install it and I can't even do it myself only the admin can.
At the moment I'm still waiting.
So I'm looking for another webhosting service again - though I will stay with hostgator because of their outstanding support service - just for being able to install Wordpress Mu.
