Being Attacked What Can I Do
May 28, 2008From running smoothly to suddenly going to 900 write requests, my web server crashes.
I don't want to be asking the DC to restart my machine every minute.
They installed Squid which solved the load and seems to run smooth. But my script doesn't function properly as everything is cached.
I then put all my images/css etc on a lighttpd server which can handle all the requests without problems.
So now apache is only handling around 30 php requests per second. But will magically jump up to 600+.
The DC says I'm being syn flooded.
I have APF, deflate DDoS, etc. installed.
Anything else I can do?
Being Attacked - DDOS?
Nov 6, 2007OK well today I found out my server was being DDOS'ed
And I know which domain is being attacked with hundreds of IP's. I am running Cpanel / WHM but I have no idea how I can stop this?
Any ideas or suggestions? Maybe redirect the DNS? to a invalid ip? But I'm not sure how i can go about doing that?
Server Is Being Attacked
Jul 1, 2009Server info:
Windows 2003 box
Dedicated server currently hosted at the planet.
Problem:
It would appear there has been a security breach into the server recently. This morning we cleared off a Trojan, and also a new user that had been created on the server.
All of our websites we host (around 200) had been affected. Almost every file had new javascript or links to an .swf, they load in iframes and are very malicious, actually giving any vistor to the site a virus.
I tracked down the embed code that I found in most files appended to the end of each file.
Below shows up in most .asp, .cfm, .html files (no spaces, just can't paste a url in here yet)...
<scRipT s rc=[url]
<scRipT sr c=[url]
Below shows up any any .js file (no spaces, just can't paste a url in here yet)...
document.writeln ("<script sr c="[url]
document.writeln ("<script sr c="[url]
So I got a script that opens up every file looking for this code and stripping it out. Seemed to work at first, but now all the sites have been rewritten again..... and again. So obviously something is overwriting this.

Getting DDos Attacked
May 28, 2008All my websites are down because a Dos attack on port 80. Rackspace basically said they can't do anything to help me unless I want them to install a $1500 a month hardware add on. They tried banning a couple ip addresses and that did not work. They recommended prolexic.com but does anyone have any other advice?

Jun 11, 2008I have been consistently attacked by Russia.
When I had apache my server would die and you couldn't even SSH. Now I have Litespeed my site loads but SUPER SUPER slow.
Last night I was SYN Flooded with 125mbps. Though they consumed nearly all my bandwidth and I owe the DC tons of cash in bandwidth now. I managed to block Russia and the load halved to about 50 and the site was still functional but intermittent.
I have been running Deflate DDoS etc to block IPs.
I'm wondering if I get a load balancer with another box, would this fix my problems?
I heard you can modify the settings somewhere to identify syn attacks and auto block them.

Is my server being attacked? Please help.
I'm using Linux RedHat el5. Recently, my server down almost at the same time everyday.
I try looking in /var/log/messages, it is flooded by this kind of message:
Dec 25 22:41:16 ls1 xinetd[3958]: START: smtp pid=430 from=173.66.124.249

Dec 25 22:41:24 ls1 kernel: ip_conntrack: table full, dropping packet.
From the log, at "from=xx.xx.xxx.xxx" are not all the same, but the same ip appeared for a while, then change to another.
I'm newbie to Linux, and donot quite understand what the this message is mean. Is this can be a cause that make my server down? Please suggest.
Site Getting Attacked At Will
Oct 11, 2007My site is getting attacked since last couple of days and the attacker brings it down in 5-10 minutes.I have to restart the apache webserver to bring it back again until he strike again.
I am trying to secure it as much as possible using .htaccess,i am able to stop almost all the perl/php scripts etc but the last time the hacker attacked the site today,i see 100s of these entries in my logs:
Code:
71.181.220.147 - - [10/Oct/2007:21:44:44 -0700] "GET /templates/template/images/content.png HTTP/1.1" 200 510 [url] "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Embedded Web Browser from: [url] .NET CLR 1.0.3705; .NET CLR 1.1.4322; Media Center PC 4.0; IEMB3; .NET CLR 2.0.50727; IEMB3)"

I'm Being DOS Attacked By A Gameserver Company!
Dec 20, 2008My internet connection started cutting out and I found it strange, I presumed it was with my ISP and so I ignored it as they're pretty crap, then it carried on today so I did some investigation (Turned on error logging for my router) so I go ahead and wait, an hour later my internet connection cuts out, to the logs!
Sat, 2008-12-20 22:01:38 - UDP Packet - Source:89.238.152.200,28960 Destination:192.168.1.103,28960 - [Firewall Log-DOS] ....
Am I correct in thinking there are multiple IP addresses "Attacking" my home network? If so, that's mighty strange and should I be worried?
I checked some of the IPs, most go to dedicateds around the world. One is a gameserver admin panel. Have these been hijacked and being used to "Attack" me?
I have a theory, be it probably wrong; The port number 28960 is used by Call of Duty 1 as the "default" port for a gameserver, and I play a lot of CoD1. Therefore, presumably, that port is open by our router, 28960, so somehow they've found this to be open and are "attacking" it. I'm not sure, but it seems possible, not sure why though.
192.168.1.103 is presumably ME on our subnet? Router is linksys

Server Being Attacked Via Http
Jun 1, 2007my friend's server is being attacked, the http processes shoots up causing the server load to go above 200 in minutes of starting httpd which causes server to die.
this is how the apache web server's access_log would log a normal http request;
------------------------------------------------------
"xx.xxx.xx.xx - - [01/Jun/2007:22:13:21] "GET /folder/name.gif HTTP/1.1" 200 877 [url]"Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)"
------------------------------------------------------
Today when the http load increased we saw hundreds of following requests;
------------------------------------------------------
"xx.xxx.xx.xx - - [01/Jun/2007:22:13:21] "GET /? HTTP/1.1" 200 16305 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)"
------------------------------------------------------
You see the difference between a legitimate http access log entry and the above one is that the legitimate one shows the filename(GET /folder/name.gif) and domain name being requested whereas the second one shows ("GET /?")
Above requests continously originate from 30 to 40 different ip addresses. Most of them russian ips, and many form US and canada to.
When i do a grep "GET /?" in access log there are thousands of these which started just today.
I cannot block each ips because i feel they have hundreds of IPs to initiate these requests from.

View 9 Replies View RelatedMy Limestone Server - Virus Attacked Or What?
Jul 23, 2009Alright guys - my server the past two weeks is just freaking ridiculous. It's a Core2Quad Q9300 2.5ghz server with 8gb of ram. It should be fast as hell. I can't move 20 e-mails in my mail client without the server grinding to a complete halt and httpd and mysql going unresponsive. Right now I'm just trying to copy a damned screen shot of the task manager performance tab and it's taking about 3 minutes to paste it - even though the CPU utilization is averaging only 20% at the moment and memory is only 2.5gb.
I restarted WAMP and now it seems to be running smoother. My Outpost firewall, though, didn't show too many connections to the server that it was maxing out.
Here's my ping responses just now while I was typing this - I was watching the firewall connections and I was only having like 60 connections to httpd, 20 connections to mysql, 5-10 to my SmarterTools mail server, and then my remote desktop connection. My network utilization got up to a whole 5% - so it's not that I have too many connections or something. Here's the ping responses:

Hacked - DDos Attacked, Downtime 1 Week...
Aug 23, 2008The attack is large enough now that the rules I've put in place aren't really helping much. Mod_evasive and mod_security are also installed, however this doesn't appear to be helping much either. The invalid user-agents hitting the site are filling up the max connections and then apache stops responding. I also tried raising the MaxClients in httpd.conf, however the vps then started hitting its memory limit.
I was on a shared plan and they moved me to a VPS same problem
Host: urljet.com
I have had one host representative thats said "I think we could take care of you but you would have to use this plan with the firewalls"

May 3, 2008If I type google.com in my address bar, it forwards me to www.google.com. This is not happening for my website right now. I think its a good idea to do this, since then search engines will have only 1 main URL for the website to index.

Oct 23, 2008I have a website which is currently hosted with streamline.net on their shared msql 11 server.
We have had several issues with them over the last few weeks where someone is using most of the server and slowing everyone elses sites down so much so they crash.
This week and weekend are my busiest time of the year (I sell fancy dress) and my site it totally unuseable.
We have phoned them and they have done nothing except ask us for a log which we have provided for short periods of time.
The down time has now got so bad that I have had only 2 sales today. I estimate I am losing approx 400 per day at the moment due to this problem.
Is there anything that I can do urgently to prevent my business from being killed by someone else.
Website Hacked
Jul 27, 2007So I'm interviewing with a company and when I typed in the URL to their website, I was met with a nasty surprise: a "hacked by so and so" message! However, after looking closer, I see that I had accidentally appended a period (".") to the end of the domain name, for example: http://www.example.com./
When I removed the period, the site appeared as normal. I don't know anything about the server other than it's IIS. Is there anything I can suggest to them when I go in to interview? I'd like to point this out to them; it may even help my chances at landing the job! (It's not related to networking, though.)

Apr 30, 2009Just this week, I believe one of my site has been hacked...or potentially my whole server! When accessing the website (a vBulletin forum), instead of going to the main page, we get a screen that looks like Window's "My Computer" and there is a scan running. Firefox has blocked the site for suspicion.
I am stumped. Where to begin? I have full SSH access to my server (after rebooting it). Thank you in advance.
