WEB BROWSER SECURITY
“Sorry dear readers,could not post new topics for the long time.I was really very busy those days.I get the time today to write something interesting,but i’m, still very busy,but I promise,I’ll come back soon with a lot of new and interesting topics for all of our readers.”
Now,come to our topic,friends,the web browsers like Internet Explorer,Mozilla etc can be used to fetch your secret documents and files.Now,let’s learn this is possible.
A Web browser is a software application that enables a user to display and interact with text, images, and other information typically located on a Web page at a website on the World Wide Web or a local area network.Web browsers communicate with Web servers primarily using HTTP (hypertext transfer protocol) to fetch webpages. HTTP allows Web browsers to submit information to Web servers as well as fetch Web pages from them. The most commonly used HTTP is HTTP/1.1, which is fully defined in RFC 2616. HTTP/1.1 has its own required standards that Internet Explorer does not fully support, but most other current-generation Web browsers do.
HOW THIS COULD BE USEDPasco (the Latin word for “Browse”) is a command line tool that runs on Unix or Windows and can reconstruct the internal structures for IE Index.dat files. Pasco accepts an Index.dat file, reconstructs the data, and outputs the information in a delimited text file format. This format is useful when you need to import the data into a spreadsheet such as Microsoft Excel. Figure 1 shows Pasco in action.Pasco shows that IE saves the following fields from a single web site visit in the Index.dat file: The record type - Pasco signifies the activity is either a URL that was browsed or a website that redirected the user’s browser to another site.
>The URL - The actual website that the user visited.
>Modified Time - The last moment in time the website was modified.
>Access Time - The moment in time the user browsed the website.
>Filename - The local file name that contains a copy of the URL listed.
>Directory - The local directory you can find the “Filename” above.
>HTTP Headers - The HTTP headers the user received when he browsed the URL.
Nowdays,most websites use CGI scripts .These scripts are located in the /cgi-bin directory.These scripts can be downloaded for further examination or even use these scripts to steal passwords to access password protected parts of the website.
So,simply type the following in the location bar of your browser,and observe what you get-
ftp://www.hostname.com/cgi-bin
The most common way to get the password file is to FTP anonymously and check if it in the /etc directory access to the passwd is restricted or not.If it is not restricted then download the file and firstly unshadow it and then crack it.First you need to find a box t hat is running the cgi-bin/phf file on their system. A great way to find out without trial and error is to go to http://www.altavista.com/ and just search on cgi-bin AND perl.exe or cgi-bin AND phf.
>>Finger box hacking: Lets say you wanted to break into somewhere like …. hmmmm AOL. The first thing we would do is type in their web site in the URL: http://www.aol.com./ The next thing we would do is add /cgi-bin/finger to the web URL so it would look like thisHttp://www.aol.com/cgi-bin/finger. If the finger gateway is operational a box should appear for you to enter the name you want to finger. If it is operational you have a chance to receive the etc/passwd file. Next thing you will probably want to do is search for a mailto on the web page… just scan the page for any mailto refs. Go back to the finger box and type in this query……

LINUX-I
LINUX BASICS
Linux is an open source,free software operating system that was initially created as a hobby by a young student, Linus Torvalds, at the University of Helsinki in Finland. Linus had an interest in Minix, a small UNIX system, and decided to develop a system that exceeded the Minix standards. He began his work in 1991 when he released version 0.02 and worked steadily until 1994 when version 1.0 of the Linux Kernel was released. The kernel, at the heart of all Linux systems, is developed and released under the GNU General Public License and its source code is freely available to everyone. It is this kernel that forms the base around which a Linux operating system is developed. There are now literally hundreds of companies and organizations and an equal number of individuals that have released their own versions of operating systems based on the Linux kernel. More information on the kernel can be found at our sister site, LinuxHQ and at the official Linux Kernel Archives. The current full-featured version is Red Hat 9 is coming..
The GNU Project was launched in 1984 to develop a complete Unix-like operating system which is free software: the GNU system. Variants of the GNU operating system, which use the kernel called Linux, are now widely used; though these systems are often referred to as “Linux”, they are more accurately called GNU/Linux systems.
What is Free Software?
“Free software” is a matter of liberty, not price. Free software is a matter of the users’ freedom to run, copy, distribute, study, change and improve the software. More precisely, it refers to four kinds of freedom, for the users of the software:•The freedom to run the program, for any purpose (freedom 0).•The freedom to study how the program works, and adapt it to your needs (freedom 1). Access to the source code is a precondition for this.•The freedom to redistribute copies so you can help your neighbor (freedom 2).•The freedom to improve the program, and release your improvements to the public, so that the whole community benefits (freedom 3). Access to the source code is a precondition for this.
Linux vs. Windows Design
•Windows has only recently evolved from a single-user design to a multi-user model. Linux is based on a long history of well fleshed-out multi-user design.•Windows is monolithic, not modular, by design but Linux is mostly modular by design.•Windows depends too heavily on an RPC model, Linux does not depend upon RPC to function, and services are usually configured not to use RPC by default.•Linux servers are ideal for headless non-local administration, whereas Windows focuses on its familiar graphical desktop interface.

E-MAIL DETAILS
Friends, after reading this article you’ll be able to know,who is sending you the message or the forge mail.Where Email Comes FromSuperficially, it appears that email is passed directly from the sender’s machine to the recipient’s. Normally, this isn’t true; a typical piece of email passes through at least four computers during its lifetime.
This happens because most organizations have a dedicated machine to handle mail, called a “mail server”; it’s normally not the same machine that users are looking at when they read their mail. In the common case of an ISP whose users dial in from their home computers, the “client” computer is the user’s home machine, and the “server” is some machine that belongs to the ISP. When a user sends mail, she normally composes the message on her own computer, then sends it off to her ISP’s mail server. At this point her computer is finished with the job, but the mail server still has to deliver the message. It does this by finding the recipient’s mail server, talking to that server and delivering the message. It then sits on that second mail server until the recipient comes along to read his mail, when he retrieves it onto his own computer, normally deleting it from the mail server in the process.
How to know email headers
Steps to open headers for various email clients and services like Outlook, Hotmail, Yahoo, AOL,…
Yahoo Mail• Log into your Yahoo! Mail account.• Click the “Options” link on the navigation bar.• Click the “General Preferences” link.• Go to the paragraph titled Messages and Locate the Show Headers heading and select “All.”• Click the “Save” button to put your new settings into effect.
GmailLog into your Gmail Account
open the Email whose headers you want to view
Click on the more options link in the message next to the date of the email. If the link says hide options then do not worry u have alreadyclicked on the more options link.
Now click the link called show original.
This will bring up a new window with headers and the body of the message.
Hotmail• Log into Hotmail.• Click on “Options” tab on the top navigation bar.• Click on the “Mail” link on the navigation bar on the left.• Click on the “Mail Display Settings” link.• Change the “Message Headers” option to “Full”.• Click the “OK” button.
AOL Mail
If the email is sent from anywhere OTHER then AOL, and you are receiving it in AOL, then open the email you want to trace, or have your client open the email, and look for the link Details. This link is usually just below the To:email in the email message. If the email is sent from an AOL user to another AOL user then our Reverse AOL Screenname search can get you the sender’s information.
Outlook Express 4, 5 and 6Start by opening the message in its own window (or when viewing the message in the preview pane). Then:With the keyboard:CTRL-F3 (Message Source Window)CTRL-A (select all)CTRL-C (copy)ALT-F4 (close)With the mouse:Click the “File” menuClick “Properties”Click the “Details” tabClick “Message Source”Highlight, copy and paste everything from this window (Ctrl-A, Ctrl-C)With viruses, worms and trojans being spread via email, many users now work with the preview screen in Outlook Express turned off. Viewing the contents of email in the preview screen is no different than opening the message. If the email has malicious content, it may execute in the preview screen.
The Importance of Received: Headers
In the above examples ,we’ve seen that the Received: headers provide a detailed log of a message’s history, and so make it possible to draw some conclusions about the origin of a piece of email even when other headers have been forged. This section explores some details associated with these singularly important headers, and in particular how to circumvent common forgery techniques.Unquestionably, the single most valuable forgery protection in the Received: headers is the information logged by the receiving host from the sender. Recall that the sender can lie about its identity (by putting garbage in its HELO command to the receiver); fortunately, modern mail transfer programs are able to detect such false information and correct it.

AUTOMATIC TELLER MACHINE
As is often the case with inventions, many inventors contribute to the history of an invention. In the case of the ATM, Don Wetzel invented the first successful and modern ATM in the USA, however he was not first inventor to create an ATM. In 1939, Luther George Simjian started patenting an earlier and not-so-successful version of an ATM. Read about Luther George Simjian here.
There are 3 major types of Automatic teller machines.
1> IBM
The first of these (and the most popular) is the IBM model. This is easilydistinguised from the others by the IBM logo in the top right hand corner ofthe front of the machine.This unit features a touch sensitive keypad and a 1 line display with a visorthat moves up and down. (The newer models have a 5 line display)..
2> NCR
The second unit is the NCR unit, which is MUCH smaller than than the IBM frontpanel. This unit has a small VDU as well as a touch sensitive keypad. The onlybanks that seem to be using this unit in Australia is the ‘STATE BANK’ ofVictoria, so you will not see many of them around.
3> PHILIPS
The third and final unit is made by Philips as is only used by the creditunions or Building Societys. This is usually known as ‘CASHCARD’. These unitsfeature a push-button keyboard and a VDU (like the NCR).
All these above units provide the same functions…
>>How Do ATMs Work?
An ATM is simply a data terminal with two input and four output devices. Like any other data terminal, the ATM has to connect to, and communicate through, a host processor. The host processor is analogous to an Internet service provider (ISP) in that it is the gateway through which all the various ATM networks become available to the cardholder (the person wanting the cash). Most host processors can support either leased-line or dial-up machines. Leased-line machines connect directly to the host processor through a four-wire, point-to-point, dedicated telephone line. Dial-up ATMs connect to the host processor through a normal phone line using a modem and a toll-free number, or through an Internet service provider using a local access number dialed by modem. Leased-line ATMs are preferred for very high-volume locations because of their thru-put capability, and dial-up ATMs are preferred for retail merchant locations where cost is a greater factor than thru-put. The initial cost for a dial-up machine is less than half that for a leased-line machine. The monthly operating costs for dial-up are only a fraction of the costs for leased-line. The host processor may be owned by a bank or financial institution, or it may be owned by an independent service provider. Bank-owned processors normally support only bank-owned machines, whereas the independent processors support merchant-owned machines.
>>Parts of the MachineYou’re probably one of the millions who has used an ATM. As you know, an ATM has two input devices:
1>> Card reader - The card reader captures the account information stored on the magnetic stripe on the back of an ATM/debit or credit card. The host processor uses this information to route the transaction to the cardholder’s bank.
2 >>Keypad - The keypad lets the cardholder tell the bank what kind of transaction is required (cash withdrawal, balance inquiry, etc.) and for what amount. Also, the bank requires the cardholder’s personal identification number (PIN) for verification. Federal law requires that the PIN block be sent to the host processor in encrypted form. And an ATM has four output devices:
1) Speaker - The speaker provides the cardholder with auditory feedback when a key is pressed. 2) Display screen - The display screen prompts the cardholder through each step of the transaction process. Leased-line machines commonly use a monochrome or color CRT (cathode ray tube) display. Dial-up machines commonly use a monochrome or color LCD.
3) Receipt printer - The receipt printer provides the cardholder with a paper receipt of the transaction.
4) Cash dispenser - The heart of an ATM is the safe and cash-dispensing mechanism. The entire bottom portion of most small ATMs is a safe that contains the cash.
>>Sensing Bills The cash-dispensing mechanism has an electric eye that counts each bill as it exits the dispenser. The bill count and all of the information pertaining to a particular transaction is recorded in a journal. The journal information is printed out periodically and a hard copy is maintained by the machine owner for two years. Whenever a cardholder has a dispute about a transaction, he or she can ask for a journal printout showing the transaction, and then contact the host processor. If no one is available to provide the journal printout, the cardholder needs to notify the bank or institution that issued the card and fill out a form that will be faxed to the host processor. It is the host processor’s responsibility to resolve the dispute. Besides the electric eye that counts each bill, the cash-dispensing mechanism also has a sensor that evaluates the thickness of each bill. If two bills are stuck together, then instead of being dispensed to the cardholder they are diverted to a reject bin. The same thing happens with a bill that is excessively worn, torn, or folded. The number of reject bills is also recorded so that the machine owner can be aware of the quality of bills that are being loaded into the machine. A high reject rate would indicate a problem with the bills or with the dispenser mechanism.
>>ATM SecurityATMs keep your personal identification number (PIN) and other information safe by using encryption software such as Triple DES (Data Encryption Standard). But there are lots of things that you can do to protect your information and your money at an ATM.Many banks recommend that you select your own PIN. Visa offers the following PIN tips:Don’t write down your PIN. If you must write it down, do not store it in your wallet or purse. Make your PIN a series of letters or numbers that you can easily remember, but that cannot easily be associated with you personally. Avoid using birth dates, initials, house numbers or your phone number. Visa also recommends the following tips for safe ATM usage:Store your ATM card in your purse or wallet, in an area where it won’t get scratched or bent. Get your card out BEFORE you approach the ATM. You’ll be more vulnerable to attack if you’re standing in front of the ATM, fumbling through your wallet for your card. Stand directly in front of the ATM keypad when typing in your PIN. This prevents anyone waiting to use the machine from seeing your personal information. After your transaction, take your receipt, card and money away. Do not stand in front of the machine and count your money. If you are using a drive-up ATM, get your vehicle as close to the machine as possible to prevent anyone from coming up to your window. Also make sure that your doors are locked before you drive up to the machine. Do not leave your car running while using a walk-up ATM. Take your keys with you and lock the doors before your transaction. If someone or something makes you uncomfortable, cancel your transaction and leave the machine immediately. Follow up with your bank to make sure the transaction was cancelled and alert the bank to any suspicious people. Many retail merchants close their store at night. It is strongly recommended that they pull the money out of the machine when they close, just like they do with their cash registers, and leave the door to the security compartment wide open like they do with an empty cash-register drawer. This makes it obvious to any would-be thief that this is not payday.It’s important to use a well-lit, public ATM machine at night. For safety reasons, ATM users should seek out a machine that is located in a well-lighted public place. Federal law requires that only the last four digits of the cardholder’s account number be printed on the transaction receipt so that when a receipt is left at the machine location, the account number is secure. However, the entry of your four-digit personal identification number (PIN) on the keypad should still be obscured from observation, which can be done by positioning your hand and body in such a way that the PIN entry cannot be recorded by store cameras or store employees. The cardholder’s PIN is not recorded in the journal, but the account number is. If you protect your PIN, you protect your account.
Information on the Plastic Cards
The Plastic Cards that you put into these cash carrying monsters have a Numberthat is printed on the front of the card (which is also the same number, thatis stored on the MAGNETIC STRIP on the back of the card.)What do these numbers mean????? Well here is some information on them…The Numbers are split up into 2 groups, the first group ALWAYS containsSIX numbers while the second group contains anywhere between 6 to 13 numbers.EG) 560192 3012565214782\ /\ / __ This 3 digit number identifies the Bank. __ This is the Australian ID code and ALL banks have this.Some ID’s for banks…………
018 - State Bank of India
192 - Westpac Banking Corporation
251 - National Australia Bank
220 - Commenwealth Bank
The Second part of the number seems to be a jumble of digits for 6 to 13, whichonly seem to make sense to the banks computer.The banks computer simply looks the second number up in a Table and finds outyour assigned PIN number (A password for your card consisting of 4 digits), and any other information. eg) Your savings account no. Cheque a/c etc.Since the four Digit PIN (Personal Identification Numbers) range from 0000 to9999, then more than one person has the same PIN number for his card. (Banks dohave more that 10,000 customers !!)Okay now that we have some simple background information we can learn how to’defeat’ the system..

The Second part of the number seems to be a jumble of digits for 6 to 13, whichonly seem to make sense to the banks computer.The banks computer simply looks the second number up in a Table and finds outyour assigned PIN number (A password for your card consisting of 4 digits), and any other information. eg) Your savings account no. Cheque a/c etc.Since the four Digit PIN (Personal Identification Numbers) range from 0000 to9999, then more than one person has the same PIN number for his card. (Banks dohave more that 10,000 customers !!)Okay now that we have some simple background information we can learn how to’defeat’ the system..
Block A Website
BLOCK UNWANTED SITE ON YOUR COMPUTER
Hey Friends,want to block any site from opening on your computer.If you want to block some site in windows O.S. to be browse from your computer.
Then do following steps………
open the location..C:\WINDOWS\system32\drivers\etcyou will find a hosts file.First backup the hosts file.Open hosts file there, from the notepad.At the end of the line you can see as per below.
127.0.0.1 localhost
Append the following line at the end127.0.0.1 BlockSitename.com Replace the BlockSitename.com with the site name that you want to block.
example……If you want to restrict http://www.yahoo.com/ then in the hosts file do this….127.0.0.1 http://www.yahoo.com/or0.0.0.0 http://www.yahoo.com/
as ip 0.0.0.0 means nothing.
Then go to Start->Run-> type: ipconfig /flushdns to restart the network.
Note: That will only stop the domain name to go to the website but if you know the IP address of the site from the gnsstuff or whois then you can brose your site.

HACKING HISTORY
HACKERS ATTACKED AGAIN
http://www.monster.com/ has been hacked by the hackers.The Hackers has always attacked the internet from time to time and most of the time they have succeeded.This time,one of the largest job search engine website has been hacked.Over 1.3 million users have been affected in this hacking.Patrick Martin, senior product manager at Symantec, said that the aim of the attack seemed to have been to gain access to user data to send more convincing spam in the hope of stealing financial information.
Great Hacks since yet.
1969Arpanet, the forerunner of the internet, is founded. The first network has only four nodes.
1971 First e-mail program written by Ray Tomlinson and used on Arpanet which now has 64 nodes.
1980In October 1980, Arpanet comes to a crashing halt by the accidental distribution of a virus.
1983The internet is formed when Arpanet is split into military and civilian sections. Wargames, a film that glamorises hacking, is released. Many hackers later claim that the movie inspired them to start playing around with computers and networks.
1986 In August, while following up a 75 cent accounting error in the computer logs at the Lawrence Berkeley Lab at the University of California, Berkeley, network manager Clifford Stoll uncovers evidence of hackers at work. A year-long investigation results in the arrest of the five German hackers who were found responsible for that.
1988Robert Morris, a graduate student at Cornell University, sets off an internet worm program that quickly replicates itself to over 6,000 hosts bringing almost the whole network to a halt. Morris is arrested soon afterwards and is punished by being fined $10,000, sentenced to three years on probation and ordered to do 400 hours of community service.Worms are different from virus.
1989Kevin Mitnick: Arrested twice for hacking.He is convicted of stealing software from Digital Equipment and codes for long-distance lines from US telephone company MCI. He is the first person convicted under a new law against gaining access to an interstate computer network for criminal purposes. He spent a one-year prison term. At the Cern laboratory for research in high-energy physics in Geneva, Tim Berners-Lee and Robert Cailliau develop the protocols that will become the world wide web.1993 Kevin Poulsen, Ronald Austin and Justin Peterson were charged for conspiring to rig a radio phone-in competition to win prizes. The trio seized control of phone lines to the radio station ensuring only their calls got through. The group allegedly netted two Porsches, $20,000 in cash and holidays in Hawaii.
1994 A 16-year-old music student called Richard Pryce, better known by the hacker alias Datastream Cowboy, is arrested and charged with breaking into hundreds of computers including those at the Griffiths Air Force base, Nasa and the Korean Atomic Research Institute. His online mentor, “Kuji”, is never found. Also this year, a group directed by Russian hackers breaks into the computers of Citibank and transfers more than $10 million from customers’ accounts. Eventually, Citibank recovered all but $400,000 of the pilfered money.
1995 In February, Kevin Mitnick is arrested for a second time. He is charged with stealing 20,000 credit card numbers. He eventually spends four years in jail and on his release his parole conditions demand that he avoid contact with computers and mobile phones.On November 15, Christopher Pile becomes the first person to be jailed for writing and distributing a computer virus. Mr Pile, who called himself the Black Baron, was sentenced to 18 months in jail. The US General Accounting Office reveals that US Defense Department computers sustained 250,000 attacks in 1995.
1996 Popular websites are attacked and defaced in an attempt to protest about the treatment of Kevin Mitnick. The internet now has over 16 million hosts and is growing rapidly.
1997Popular Internet search engine Yahoo! is hit by hackers claiming a “logic bomb” will go off in the PCs of Yahoo!’s users on Christmas Day 1997 unless Kevin Mitnick is released from prison. “There is no virus,” Yahoo! spokeswoman Diane Hunt said. Hackers pierce security in Microsoft’s NT operating system to illustrate its weaknesses.AOHell is released, a freeware application that allows a burgeoning community of unskilled hackers–or script kiddies–to wreak havoc on America Online. For days, hundreds of thousands of AOL users find their mailboxes flooded with multi-megabyte mail bombs and their chat rooms disrupted with spam messages.
1998 Anti-hacker ad runs during Super Bowl XXXII. The Network Associates ad, costing $1.3-million for 30 seconds, shows two Russian missile silo crewmen worrying that a computer order to launch missiles may have come from a hacker. They decide to blow up the world anyway.In January, the federal Bureau of Labor Statistics is inundated for days with hundreds of thousands of fake information requests, a hacker attack called “spamming.”Hackers break into United Nation’s Children Fund Web site, threatening a “holocaust” if Kevin Mitnick is not freed.Hackers claim to have broken into a Pentagon network and stolen software for a military satellite system. They threaten to sell the software to terrorists.The U.S. Justice Department unveils National Infrastructure Protection Center, which is given a mission to protect the nation’s telecommunications, technology and transportation systems from hackers.Hacker group L0pht, in testimony before Congress, warns it could shut down nationwide access to the Internet in less than 30 minutes. The group urges stronger security measures.
The hacking group Cult of the Dead Cow releases its Trojan horse program, Back Orifice–a powerful hacking tool–at Def Con. Once a hacker installs the Trojan horse on a machine running Windows 95 or Windows 98, the program allows unauthorized remote access of the machine.
1999David Smith,The Creator of the Melissa virus.In March, the Melissa virus goes on the rampage and wreaks havoc with computers worldwide. After a short investigation, the FBI tracks down and arrests the writer of the virus, a 29-year-old New Jersey computer programmer, David L Smith.
2000 In February, some of the most popular websites in the world such as Amazon and Yahoo are almost overwhelmed by being flooded with bogus requests for data.In May, the ILOVEYOU virus is unleashed and clogs computers worldwide. Over the coming months, variants of the virus are released that manage to catch out companies that didn’t do enough to protect themselves.In October, Microsoft admits that its corporate network has been hacked and source code for future Windows products has been seen.
2001DNS AttackMicrosoft becomes the prominent victim of a new type of hack that attacks the domain name server. In these denial-of-service attacks, the DNS paths that take users to Microsoft’s Web sites are corrupted. The hack is detected within a few hours, but prevents millions of users from reaching Microsoft Web pages for two days.

PROGRAMMING TIPS
Ms Dos And Batch File Programming Tricks And Tips
DOS is basically a file caled command.com .It is this file which handles all DOS commands that we give at DOS prompt-such as copy,dir,del,etc.
Batch file programming is nothing but the windows version of unix shell programming.To perform a bulk set of commands over and over again,batch files are used.
Some Important And Hidden Dos Command1>ANSI.SYS - Defines functions that change display graphics, control cursor movement, andreassign keys. 2>ARP - Displays, adds, and removes arp information from network devices3>AT - Schedule a time to execute commands or programs.4>COLOR - Easily change the foreground and background color of the MS-DOS window.5>CONTROL - Open control panel icons from the MS-DOS prompt.6>CTTY - Change the computers input/output devices.7>EMM386 - Load extended Memory Manager.8>IFSHLP.SYS - 32-bit file manager.9>SWITCHES - Remove add functions from MS-DOS.10>SYS - Transfer system files to disk drive.
Redirection Of OUTPUT:Send the output of the dos prompt to a file on disk.This can be done using the Redirection operator,> .Example: c:\windows>net>xyz.txtc:\windows>help>>xyz.txtThis command will execute the net command and will store the results in thetext file ,xyz.txt.To print the results: c:\windows>dir*.*>prnRedirection of Input: we can also redirect input ,from .txt file to DOS prompt.Example: c:\windows> more <>
BATCH PROGRAM TO DELETE FILES:
