Penetration Testing is an exercise that attempts to simulate the techniques adopted by an attacker to compromise your systems. It helps to highlight those vulnerabilities which could be exploited by a remote unauthorized attacker. NII's penetration testing service is a highly creative, out-of-the-box engagement, and often results in new vulnerabilities being discovered or a new tool being developed from such an exercise.

Sample report from a penetration testing exercise we carried out for a large enterprise
Advisories of security vulnerabilities we discover - some of them during routine penetration tests
Articles that have appeared in various publications, again highlighting our innovative approach
Presentations we have made at various security forums, especially on application security
A penetration testing exercise can be structured in various ways:
Application Security Audits
A penetration test could focus exclusively on your web applications. This could be done at various levels
Black-box testing: Here, we only know the URL of the website. Enumeration of technologies, mapping of the website, identification of fault injection points, determining input validation vulnerabilities, or logical security vulnerabilities, and the OWASP top 10 attacks are all part of this exercise.
Grey-box testing: Often enough, a web application involves authentication and authorization components. In order to be able to test these, we request for a dummy user account with the least level of privileges within the application. Using this account, we are able to log in and test for various flaws in the authentication scheme, as well as attempt to escalate our privileges and bypass authorization restrictions. Read our list of advisories here.
Network penetration testing
This type of a penetration test involves identifying the targets through Google searches, WHOIS, DNS queries, etc. Fingerprinting and identifying vulnerabilities. Exploitation of these vulnerabilities depends on whether it is part of the engagement or not. Limited exploitation is always done in terms of password guessing, directory traversals, file uploads, etc. However, stronger exploitation such as Denial of Service attacks, Buffer Overflow exploits, etc., are carried out only if the possible fallouts from such exploitation are accepted prior to the engagement.
Automated port identification
n large and very large networks, the number of public IP addresses, and the ports exposed on these IP addresses can vary on a daily basis. What is required is an automated way to periodically scan a large range of IP addresses, determine what ports are open, and attempt to identify the service running on those ports. What is even more important is to produce trending analyses reports, which show new IP addresses or new ports that have appeared since the last scan was run. NII offers a secure portal to its customers, where they can log in, enter their ranges, run the scans, view the reports and compare with previous scans.

Basic overview of this tutorial is if there's some kind of timer or client
software on the computer you're using at the Net Cafe you can hopefully disable it.
Firstly we need to gain access to command prompt (cmd.exe) to do this there's a few
ways.
1) The most basic is to go Start/Run/cmd.exe and a black input screen should pop up.
Say that's disabled then we can try some other methods.
2) Press the Windows Logo + R and it will start run up. (hopefully)
3) Navigate your way to C:\WINDOWS\system32 and run cmd.exe from in there.
4) Open notepad type "cmd.exe" without the quotation marks ("") and then
go to File/Save As.. and type the name for the file and have it end with
.bat for example "MyNewFile.bat" and select Save as type and select All Files.
Make sure to save it somewhere you can access it, Like the desktop.
If they have deleted Notepad then go in to Internet Explorer and right click
and select View Source or on the menu bar click View then source and perform the
same process as above.
Once you have done this you can run the file. If you can't open files from the desktop
then go back into Internet Explorer and go to View/Explorer Bar/Folders and navigate to
the Desktop and it will show the saves files on the desktop in a folder type window.
Once you have access to command prompt you can perform some usefull actions e.g shutdown
programs, shutdown other peoples computers, add new accounts.
Ok, well most Net cafes have software running that boots you off of the machine after a certain
ammount of time unless you pay for more time. Well, we don't want that to happen now do we?
Firstly try figure out the Net Cafes timeing/credit softwares name cause this can help.
For more info on the software running we can use the command "tasklist" inside of command prompt.
example: "tasklist" (without quotation marks)
Basicly it brings up all the processes running.
Now say we know the process name for the Net Cafes software we need to disable it. So, how do we do that?
we use "taskkill" >:]
Basicly kills the process we specifcy. Say the Net Cafes software is "Timer.exe" for example and it's shown in
the task list like that we would do this.
example: "taskkill /im Timer.exe /f"
/im : is for image name. Not quite sure what it means, but we need it.
Timer.exe : that's the Net cafes software/process name (example)
/f : Forcefully shuts the program.
Now hopefully your Net Cafes software is terminated and you can freely use their computer with no time restriction.
If you have no luck finding the Net Cafes software name then just try ending processes that Windows Doesn't rely on.
Perhaps you want to have a little fun with people on the network at the Net cafe? well here's a few things for you
to do with command prompt.
Find the people on the network with "net view" and it will list the other computers names on the network.
The shutdown command. Basically the shutdown command will shutdown a computer on the network or your own computer (comes in
handy)
example: "shutdown -s -m HJCPwnts -t 20 -c You're being shutdown"
use "shutdown -a" to cancel this action so you don't shut your own computer down.
-s : sets the shutdown action.
-m : specify the computer name (HJCPwts) that's what my computer name would be on the network. (to find out
how to find computer names use net view. It will list the other computer names.)
-t : the time until shutdown in seconds. Just specify it for 0 if you want it instant.
-c : the comment that will be shown on the shutdown window (not needed, but goo to leave the victim a message)
-f : I left this one out because it shuts the applications the user is running down, but add it on the end when doing
it to someone else.
Now for some more stuff. Perhaps we want to create a new account on this computer and login to it? Well, lets do it then. Ok, this is how we do it.
In command prompt type "net user CoolGuy /add" this basically adds a new user by the name of CoolGuy. Simple ehh?
well we have struck a problemo. How the hell do we login to that account? EASY!
In fact we have already covered most of it. We will be using the shutdown command again.
"shutdown -l" : basicly this logs us out and we can log back in with the CoolGuy account.
-l : sets the logout action.
Ok, so you have had your fun with the new account now and you want to get rid of it in case
of the Net Cafe staff finding it. Well that's simple aswell, all we do is..
"net user CoolGuy /delete" and it will delete that user. Make sure to check it has been
deleted by using "net user" and it will show the accounts.

The Most Dangerous Web Search Terms
do you know Which search terms would make it on the list if you would have to compile a list of the ten most dangerous web search terms?
Most users would probably add search terms like warez, cracks and sex when asked to compile a top ten list.
A recent McAfee study on the other hand came to a completely different conclusion. The ten most dangerous web search terms are everyday search terms that cannot be connected easily with malicious intent. The top spot is occupied by searches for Screensavers, followed by free games, work from home and Rihanna with Barrack Obama, the iPhone and Taxes in the list as well. It should however be noted that the top 10 list is made up of categories and not single search terms.
Whats your search terms?
..Hm..

How to Secure a Wireless Network from Hackers?
The reason we secure a wireless network is to stop people from using the services of our network who don't have permission to utilize them. It is harder to secure a wireless network from hackers as compared to a classic wired network. This is due to the fact that a wireless network can be accessed anywhere inside the range of its antenna.
In order to secure a wireless network from hackers, we should take proper steps to save ourselves against security issues. If you don't secure a wireless network from hackers, you might end up without its service. The consequence might also include the utilization of our network to attack further networks. To secure a wireless network from hackers, you should follow these simple wireless networking tips:
1. Strategic antenna placement:
The first thing you have to do is to position the access point's antenna in a place which restricts the range of its signal to go further than the required area. You should not put the antenna close to a window because glass can't obstruct its signals. Place it in a central location of the building.
2. Use WEP:
WEP stands for Wireless encryption protocol. It's a customary technique for encrypting traffic on a wireless network. You should never skip it as that will allow hackers to get instant access to the traffic over a wireless network.
3. Change the SSID, disable the broadcast of SSID:
SSID stands for service set identifier. It is the recognition thread utilized by the wireless access point due to which the customers are capable of starting connections. For every wireless access point arranged, select an exclusive as well as unique SSID. Also, if it's attainable, hold back the broadcast of the SSID out over the antenna. It won\t appear in the listing of offered networks, while being able to provide services as usual.
4. Disable DHCP:
By doing this, the hackers will have to decode the TCP/IP parameters, subnet mask as well as the IP address in order to hack your wireless network.
5. Disable or modify SNMP settings:
Change the private as well as public community settings of SNMP. You can also just disable it. Otherwise the hackers will be able to utilize SNMP to get significant info regarding your wireless network.
6. Utilize access lists:
For additional security of your wireless network, and if your access point support this feature, employ an access list. An access list lets us determine precisely which machinery is permitted to attach to an access point. The access points which include the access list can employ trivial file transfer protocol (TFTP) now and then in order to download modernized lists to steer clear of hackers.
