Stay Annoumoys while Black-box Penetration Testing (Tor and Proxychain)

During the black-box penetration testing sometimes we need  to hide our identity and stay anonymous, sometimes some firewalls and IDPS detect us while we are testing the machine, and might block our IP address. In this manner we need to keep changing the IP. So if the firewall blocks the companies IP so, then even if you change the local IP you may not have access to the website again. So the best way to hide the identity, is to you Tor and proxychain.

Install tor:

Apt-get install tor

 Then you just need to run tor service.

 Service tor start

So then you need to modify your proxychain configuration and polish it a little bit. So open the proxychain and uncomment the dynamic, comment the static, and at the end of the file you may find the socks4 127.0.0.1 9050.0.

You need to add the following code as well.

socks5 127.0.0.1 9050

************************Notice:*******************************

The file should be look like bellow after editing.

# proxychains.conf  VER 3.1

#

#        HTTP, SOCKS4, SOCKS5 tunneling proxifier with DNS.

#

# The option below identifies how the ProxyList is treated.

# only one option should be uncommented at time,

# otherwise the last appearing option will be accepted

#

dynamic_chain

#

# Dynamic – Each connection will be done via chained proxies

# all proxies chained in the order as they appear in the list

# at least one proxy must be online to play in chain

# (dead proxies are skipped)

# otherwise EINTR is returned to the app

#

#strict_chain

#

# Strict – Each connection will be done via chained proxies

# all proxies chained in the order as they appear in the list

# all proxies must be online to play in chain

# otherwise EINTR is returned to the app

#

#random_chain

#

# Random – Each connection will be done via random proxy

# (or proxy chain, see  chain_len) from the list.

# this option is good to test your IDS :)

# Make sense only if random_chain

#chain_len = 2

# Quiet mode (no output from library)

#quiet_mode

# Proxy DNS requests – no leak for DNS data

proxy_dns

# Some timeouts in milliseconds

tcp_read_time_out 15000

tcp_connect_time_out 8000

# ProxyList format

#       type  host  port [user pass]

#       (values separated by ‘tab’ or ‘blank’)

#

#

#        Examples:

#

#                    socks5        192.168.67.78        1080        lamer        secret

#                http        192.168.89.3        8080        justu        hidden

#                 socks4        192.168.1.49        1080

#                http        192.168.39.93        8080

#

#

#       proxy types: http, socks4, socks5

#        ( auth types supported: “basic”-http  “user/pass”-socks )

#

[ProxyList]

# add proxy here

# meanwile

# defaults set to “tor”

socks4         127.0.0.1 9050

socks5 127.0.0.1 9050

And the restart your tor service:

Service tor restart

Now you can open any application or browser using proxychain with the following command:

proxychains iceweasel www.ipchicken.com

Or

Proxychain nmap yourtargetip

Please let me know how do you keep your identity anonymous during penetration testing.

How to Add or Custom Linux Terminal banner

Have you ever considered how you can add a banner to your terminal to have a more customized Linux? Many of the time I saw in many people Linux terminal that they have a title or they have their name in their terminal just like the following image:

Capture

To do so, you may install figlet, with the following command:

Apt-get install figlet

You may find more info about the figlet from http://linux.die.net/man/6/figlet. So once you have installed the figlet, you need to go to your root directory you can see the .bashrc file (if your show hidden files option is already checked). Or you can use the terminal directly:

leafpad /root/.bashrc

Then open it with your text editor and bottom of the file in the last line you may add your text as:

Figlet “your name” –c

-c switch set it in the center.

Save the file and open your terminal and enjoy your new terminal.

You may use other alternative tools with different options as well. For more info check the mewbies.com

Social Media Forensics- EC-Council Hackway Workshop Presentation

This Presentation involves with Social Media Forensics such as Email Tracing and investigation the Fraud, Scam… etc.. In the next section we covered the Twitter, Facebook, and Linkdin Forensics practically. After the video call and Instant Messaging tools, Skype is chosen because it is one of the top most popular chatting, voice/video calls (free and commercial plans). We demonstrated practically how to extract the chat conversation, contacts, call logs and much more information. Malware distribution is quite common is social media by social engineering techniques. We performed the analysis to how analysis and investigate the malware and social media investigation with malware distribution and social engineering perspective.

 

Windows warning, Question about “Your computer is correctly configured, but the device or resource (DNS Server) Is not responding”

Updating windows 8 and right after restarting, the DNS Server problem raised up out of no where

Today why the sun was shining ;), and everything was fine, my laptop notified me that, hey, you need you to update your windows. Alright, let’s do it to enjoy new security patches and fixes that Microsoft usually provides for us, :D right after updating and restarting, I couldn’t get access to the internet anymore. I could ping, but no application could access to the internet. Hey Mr Trouble (windows) I updated you to fix your problem, not to create new problems. I checked the firewall, Antivirus, and malware scanners. Everything was fine. Here are the steps I have gone through to solve the problem.

 

Restarting the Router:

Sorry, I am not the network administrator, so I don’t have any physical access to restart the university network. I couldn’t go for it, so let’s try the rest of option that I could try to solve it. Obviously I couldn’t restart the router to the default setting.

 

Renew IP addresses

I tried the “ipconfig/release” and ipconfig/renew commands, but it didn’t work

 

Restarting the DNS and DHCP services

Let’s try services.msc  (just type it in your Run), I just checked  if DNS and DHCP services are not stopped  for any unexpected reason. Both of their status were running, although I restart it. (This is windows, always restart is the first option). Nothing happened.

 

Should I Flush the DNS?

Hey Sina lets flush the DNS maybe it worked. I ran the “ipconfig/flushdns” and then “ipconfig/registerdns”.

Did it work? Hell nooo.

 

Open DNS or Google DNS

Alright buddy let’s try googleDNS/openDNS

Google DNS
8.8.8.8
8.8.4.4

Open DNS
208.67.222.222
208.67.220.220

 

It worked yeaaaaa  \m/.

Hey Mr Microsoft, this is why people prefer to go for Linux/Mac. You wanted to fix some issues; you made some new issues for me today. Although, Dear Linux has her own complicated problems, still I prefer Ms. Linux J

 

How to increase the VMware VIrtual Machine Hard Disk, and OS Hard Disk within the Virtual Machine

Many of the time we create a VMware virtual machine with a small amount of (e.g. 6 GB) for Virtual Disk. After a while, we face “low disk space” error. I had such problem few days ago.  After a bit digging google, I find out how to expand the Virtual Disk capacity. To do this, first, you need to turn off the virtual machine, and then make sure there is no snapshot, or cloned or linked VM. Then just follow as follow.

chose utilities chose expand

Chose Utilities to expand

 

Then, as the following image you can increase the Virtual Hard Disk as much as you like.

 Chose the maximum disk size as you need

Chose the maximum disk size as you need

So now you can increase the hard disk of the virtual machine Operating System as well. Let’s assume that, the VM operating system is windows XP. Just download the Gparted.iso. This tool works with any Linux, Mac and Windows machines. After downloading the Gparted.iso, boot the VM with it. Just leave all the questions as default until you get the main page. You can increase the size in the gparted very easily.

The last picture shows how to increase the OS hard disk size.
