tips n trick "Make a Trojan Horse"

Most of you may be curious to know about how to make a Trojan or Virus on your own. Here is an answer for your curiosity. In this post I’ll show you how to make a simple Trojan on your own using C programming language. This Trojan when executed will eat up the hard disk space on the root drive (The drive on which Windows is installed, usually C: Drive) of the computer on which it is run.
Also this Trojan works pretty quickly and is capable of eating up approximately 1 GB of hard disk space for every minute it is run. So, I’ll call this as Space Eater Trojan. Since this Trojan is written using a high level programming language it is often undetected by antivirus. The source code for this Trojan is available for download at the end of this post. Let’s see how this Trojan works.
Before I move to explain the features of this Trojan you need to know what exactly is a Trojan horse and how it works. As most of us think a Trojan or a Trojan horse is not a virus. In simple words a Trojan horse is a program that appears to perform a desirable function but in fact performs undisclosed malicious functions that allow unauthorized access to the host machine or create a damage to the computer.
Now lets move to the working of our Trojan
The Trojan horse which I have made appears itself as an antivirus program that scans the computer and removes the threats. But in reality it does nothing but occupy the hard disk space on the root drive by just filling it up with a huge junk file. The rate at which it fills up the hard disk space it too high. As a result the the disk gets filled up to 100% with in minutes of running this Trojan.
Once the disk space is full, the Trojan reports that the scan is complete. The victim will not be able to clean up the hard disk space using any cleanup program. This is because the Trojan intelligently creates a huge file in the Windows\System32 folder with the .dll extension. Since the junk file has the .dll extention it is often ignored by disk cleanup softwares. So for the victim, there is now way to recover the hard disk space unless reformatting his drive.
The algorithm of the Trojan is as follows
  1. Search for the root drive
  2. Navigate to WindowsSystem32 on the root drive
  3. Create the file named “spceshot.dll”
  4. Start dumping the junk data onto the above file and keep increasing it’s size until the drive is full
  5. Once the drive is full, stop the process.
You can download the Trojan source code HERE. Please note that I have not included the executabe for security reasons. You need to compile it to obtain the executable.
How to compile, test and remove the damage?
Compilation:
For step-by-step compilation guide, refer my post How to compile C Programs.
Testing:
To test the Trojan, just run the SpaceEater.exe file on your computer. It’ll generate a warning message at the beginning. Once you accept it, the Trojan runs and eats up hard disk space.
NOTE: To remove the warning message you’ve to edit the source code and then re-compile it.
How to remove the Damage and free up the space?
To remove the damage and free up the space, just type the following in the “run” dialog box.
%systemroot%\system32
Now search for the file “spceshot.dll“. Just delete it and you’re done. No need to re-format the hard disk.
NOTE: You can also change the ICON of the virus to make it look like a legitimate program.

Tips n Trick "Use Windows 7 Without Activation"

Most of you might be aware of the fact that it is possible to use Windows 7 and Vista for 120 days without activation. This is actually possible using the slmgr -rearm command which will extend the grace period from 30 days to 120 days. However in this post I will show you a small trick using which it is possible to use Windows 7 without activation for approximately an year! Here is a way to do that.
1. Goto “Start Menu -> All Programs -> Accessories” . Right click on “Command Prompt” and select “Run as Administrator“. If you are not the administrator then you are prompted to enter the password, or else you can proceed to step-2.
2. Now type the following command and hit enter
slmgr -rearm
3. You will be prompted to restart the computer. Once restarted the trial period will be once again reset to 30 days. You can use the above command for up to 3 times by which you can extend the trial period to 120 days without activation.
4. Now comes the actual trick by which you can extend the trial period for another 240 days. Open Registry Editor (type regedit in “Run” and hit Enter) and navigate to the following location
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform
5. In right-side pane, change value of SkipRearm to 1.
6. Now you will be able to use the slmgr -rearm command for another 8 times so that you can skip activation process for another 240 days. So you will get 120 + 240 = 360 days of free Windows 7 usage.
120 days using “slmgr -rearm” command before registry edit
+
240 days using “slmgr -rearm” command after registry edit
= 360 Days

tips n trick "Optimizing Windows Speed"

How to optimize the Windows performance by removing unwanted programs from startup using windows registry. Applicable to Windows XP, Vista, Windows 2000, windows 98 and windows server.
I will start hacking tips with a very useful and easy to do job. Most of us face this problem of computer slowing down; windows operating system takes ages to load when started, windows explorer hangs up and also how to find out whether your computer is infected.
Follow these steps:
1. Start and click on run in case of windows XP, Server, windows 98, and 2000 but in vista type directly in search box.
2. Type Regedit in the run box to open registry editor.
3. Go to file menu and click on export to create a back up of registry, save it on your drive other than your default windows directory.
Find out the current programs which are starting up with windows
After opening Registry editor click on HKEY_LOCAL_MACHINE
Software\
Microsoft\
Windows\
Current Version\
Run
You will see something like this on right hand pane in your registry editor
Now it’s time to get rid of the programs those slow down your operating system and possible may be a Trojan horse hiding in your hard disk.
Right click on any program to delete the entry, which you don’t want to be loaded during startup; personally I would only keep anti virus program entries.
Now you can repeat the same process with HKEY_LOCAL_USER entries and keep only Cftmon.exe for your computer sound to be working.
After deleting the unwanted program registry entries, restart the system and feel the difference in speed.

How to Protect an Email Account

Today in this post I’ll teach you how to protect your email account from being hacked. Nowadays I get a lot of emails where most of the people say “My Email account is hacked please help…”. Now one question which arises in our mind is: “Is it so easy to hack an email account? OR Is it so difficult to protect an email account from being hacked?”. The single answer to these two questions is “Absolutely NOT!”. It is neither easy to hack an email nor difficult to protect an email account from bieng hacked.
If this is the case, then what is the reason for many people to lose their accounts?
The answer is very simple. They don’t know how to protect themselves from being hacked! In fact most of the people who lose their email accounts are not the victims of hacking but the victims of Trapping. They lose their passwords not because they are hacked by some expert hackers but they are fooled to such an extent that they themselves give away their password.
Are you confused? If so continue reading and you’ll come to know…
Now I’ll mention some of the most commonly used online scams which fool people and make them lose their passwords. I’ll also mention how to protect your email account from these scams.
1. WEBSITE SPOOFING
Website spoofing is the act of creating a website, with the intention of misleading the readers. The website will be created by a different person or organisation (Other than the original) especially for the purposes of cheating. Normally, the website will adopt the design of the target website and sometimes has a similar URL.
For example a Spoofed Website of Yahoo.com appears exactly same as Yahoo Website. So most of the people believe that it is the original site and lose their passwords. The main intention of spoofed websites is to fool users and take away their passwords. For this,the spoofed sites offer fake login pages. These fake login pages resemble the original login pages of sites like Yahoo,Gmail,Orkut etc. Since it resemble’s the original login page people beleive that it is true and give away their username and passwords by trying to login to their accounts.
Solution:
Never try to login/access your email account from the sites other than the original site.
Always type the URL of the site in the address bar to get into the site. Never click on the hyperlink to enter the site.
2. BY USING KEYLOGGERS
The other commonly used method to steal password is by using a Keylogger. A Keylogger is nothing but a spyware. The detailed description of keylogger and it’s usage is discussed in the post Hacking an email account. If you read this post you’ll come to know that it is too easy to steal the password using a keylogger program. If you just access your email account from a computer installed with keylogger, you definitely lose your password. This is because the keylogger records each and every keystroke that you type.
Solution:
Protecting yourselves from a keylogger scam is very easy.Just install a good anti-spyware program and update it regularly. This keeps your PC secure from a keylogger. Also there is a program called Anti-keylogger which is specially designed to detect and remove keyloggers. You can use this program to detect some stealth keyloggers which remain undetected by many anti-spyware programs.
3. ACCESSING YOUR EMAIL ACCOUNT FROM CYBER CAFES
Do you access your email from cyber cafes? Then definitely you are under the risk of loosing your password.In fact many people lose their email account in cyber cafes. For the owner of the cyber cafe it’s just a cakewalk to steal your password. For this he just need’s to install a keylogger on his computers. So when you login to your email account from this PC, you give away your password to the cafe owner. Also there are many Remote Administration Tools (RATs) which can be used to monitor your browsing activities in real time.
This doesn’t mean that you should never use cyber cafes for browsing the internet. I know, not all the cyber cafe owners will be so wicked but it is recommended not to use cafes for accessing confidential information. If it comes to the matter of security never trust anyone, not even your friend. I always use my own PC to login to my accounts to ensure safety.
So with this I conclude my post and assume that I have helped my readers to protect their email accounts from being hacked. Please pass your comments…
