what does the new DNS threat mean to you ??

what does the new DNS threat mean to you ??
ok since this has become such a big issue in the security world now. i thought it would be nice to write a small article on it .
**********************
->Lets 1st understand what exactly is a DNS ??
DNS or Domain Name Servers play a vital role in the working of internet .
You every day go to different websites like
www.google.com
www.orkut.com
www.viruswriting.co.cc
These maybe easier to remmember for a human but they are all but useless for the machine .
The machine doesnt understand what you mean by say “www.google.com”.Dns comes into the picture here /
As you must be knowing each computer on the internet is provided with a unique ip address .
A ip address usually looks like ###.###.###.### , its a combination of numbers . Its a 32-bit numbers normally
expressed as four “octets” in a “dotted decimal number.”The four numbers are called octets because the numbers can
have a value between 0-256(28). Now if you tell the machine to take you to say 66.102.9.147 it will understand but when you
tell it to take you to www.google.com , as we discussed above , it wont . This is where dns plays a vital role , it tells the machine
the ip address of the host name that you want to access. Servers usually have static ip while the end users have dynamic(ip changes
everytime you login back to your isp ) .Seems like a easy task doesnt it ? ,but consider this with millions of people
pouring in millions of requests every second .To this add the no of end users and their changing ips and sometimes changing ip of the server.
This becomes complicated.
If you r intrested in any more details about How dns works in details please see
http://www.howstuffworks.com/dns.htm
and yes you can google too .):
*********************
The Flaw :-
–>The Timeline.
Now the latest flaw that has made the security world get up and take notice is the flaw in how the Doman name servers convert the ips from host name
sent to them. Apparently the flaw has been around for years and some experts even knew about it , theres a website (youl find it through google ) that claims
to have 1st found the flaw some years back and are angry that no one took notice of them . They also claim to have made a patch for it . But according to the
mass media it was 1st found by Dan Kamisky somewhere around last year(which i seriously doubt ) . So all the top notch security experts spent around a year
on it to find out a way to patch the. They claim to have found a patch (which i seriously doubted from the 1st day when the reports started flooding it ). Anyway in
between this the details of the flaw were put on the net by one of the them . This lead to it being transfered to all the apparent bad guys. Metasploit has put it on its
latest update and there are reports that even neosploit has (even though the complete project had stoped according to reports in mass media !lol!!! ). Well you must be wondering since the patch has already been found why is this moron writing an article on it .Well thats the catch , the apparent patch which fixes it all doesnt really fix it .
Recently aol and the kaspreskys dns were hacked using the same flaw even though they had patched it long back. In aols case the poisoned website was google.com.
Every user of its internet service who tried to go to google.com was instead sent to a websites which had adds .The objective was to only earn using the clicks on the adds,nothing more .But it could have been much dangerous. And just a day before , it was reported that a Russian physicist, Evgeniy Polyakov , had written in his blog that he was able to fool around a patched dns using a high speed internet service(2mbps is more than enough ) and a desktop computer(courtesy NYT ).
—>Why are the apparent bad guys behind this flaw ???
Obviously to exploit it.lol!!
The main objective of any person who uses this flaw would be phishing.Lets take an example , lets say iam able to poison the dns server of say , bsnl(i can tell you that it is exploitable , they haven’t even patched yet !!!) and i poison gmail entry . Next i create a small website which loads just like gmail, but sends the passwords also to me , so it would send the passwords to me as well as the gmail server. You wont see anything wrong , the address would remain same , everything will happen like it would normally would ,except that i would have your password . Now imagine if this would happen to a goverment site or say a bank site , before you even know , the complete bsnl users would be banckrupt. Moreover selling these details is a big business.
**********************
Technical details :iam not posting them over here , any one who is serious enough about this would already have them and if you dont metasploit is the hint !
**********************
What can You do about it ???
Pretty much nothing . Now since the new patch doesnt work completely you would still be exploitable. Even if we consider the situation where the patch gives us some protection, even after you patch you would still end up being vulnerable if your isp doesnt patches itselg .
What the big players are doing ???
Yahoo has started a service called sign-in seal . This would be helpful as chances are that the “apparent bad guys” wont be able to do the same .
There are reports that major players like IBM,Microsoft and Google are moving away from the whole user password (mnemonics) to cryptography which doesnt require the person to enter the password but forms a dirrect connection .(courtsey again NYT)
These doesnt help in any way in the whole DNS scenario . But certainly helps in the whole phishing scenario.

How Hackers Work

Introduction to How Hackers Work

Thanks to the media, the word "hacker" has gotten a bad reputation. The word summons up thoughts of malicious computer users finding new ways to harass people, defraud corporations, steal information and maybe even destroy the economy or start a war by infiltrating military computer systems. While there's no denying that there are hackers out there with bad intentions, they make up only a small percentage of the hacker community.



Hackers from around the world gather at camps to
practice their hobby and trade tips.

The term computer hacker first showed up in the mid-1960s. A hacker was a programmer -- someone who hacked out computer code. Hackers were visionaries who could see new ways to use computers, creating programs that no one else could conceive. They were the pioneers of the computer industry, building everything from small applications to operating systems. In this sense, people like Bill Gates, Steve Jobs and Steve Wozniak were all hackers -- they saw the potential of what computers could do and created ways to achieve that potential.

A unifying trait among these hackers was a strong sense of curiosity, sometimes bordering on obsession. These hackers prided themselves on not only their ability to create new programs, but also to learn how other programs and systems worked. When a program had a bug -- a section of bad code that prevented the program from working properly -- hackers would often create and distribute small sections of code called patches to fix the problem. Some managed to land a job that leveraged their skills, getting paid for what they'd happily do for free.

As computers evolved, computer engineers began to network individual machines together into a system. Soon, the term hacker had a new meaning -- a person using computers to explore a network to which he or she didn't belong. Usually hackers didn't have any malicious intent. They just wanted to know how computer networks worked and saw any barrier between them and that knowledge as a challenge.

In fact, that's still the case today. While there are plenty of stories about malicious hackers sabotaging computer systems, infiltrating networks and spreading computer viruses, most hackers are just curious -- they want to know all the intricacies of the computer world. Some use their knowledge to help corporations and governments construct better security measures. Others might use their skills for more unethical endeavors.

In this article, we'll explore common techniques hackers use to infiltrate systems. We'll examine hacker culture and the various kinds of hackers as well as learn about famous hackers, some of whom have run afoul of the law.

Hackers and Crackers
Many computer programmers insist that the word "hacker" applies only to law-abiding enthusiasts who help create programs and applications or improve computer security. Anyone using his or her skills maliciously isn't a hacker at all, but a cracker.
Crackers infiltrate systems and cause mischief, or worse. Unfortunately, most people outside the hacker community use the word as a negative term because they don't understand the distinction between hackers and crackers.



The Hacker Toolbox

The main resource hackers rely upon, apart from their own ingenuity, is computer code. While there is a large community of hackers on the Internet, only a relatively small number of hackers actually program code. Many hackers seek out and download code written by other people. There are thousands of different programs hackers use to explore computers and networks. These programs give hackers a lot of power over innocent users and organizations -- once a skilled hacker knows how a system works, he can design programs that exploit it.



The ILOVEYOU Computer Virus was a malicious program
that plagued computers worldwide and caused millions of dollars in damages.

Malicious hackers use programs to:

* Hack passwords:There are many ways to hack someone's password, from educated guesses to simple algorithms that generate combinations of letters, numbers and symbols. The trial and error method of hacking passwords is called a brute force attack,meaning the hacker tries to generate every possible combination to gain access. Another way to hack passwords is to use a dictionary attack, program that inserts common words into password fields.
*Infect a computer or system with a virus: Computer viruses are programs designed to duplicate themselves and cause problems ranging from crashing a computer to wiping out everything on a system's hard drive. A hacker might install a virus by infiltrating a system, but it's much more common for hackers to create simple viruses and send them out to potential victims via email, instant messages, Web sites with downloadable content or peer-to-peer networks.
* Log keystrokes: Some programs allow hackers to review every keystroke a computer user makes. Once installed on a victim's computer, the programs record each keystroke, giving the hacker everything he needs to infiltrate a system or even steal someone's identity.
Gain backdoor access: Similar to hacking passwords, some hackers create programs that search for unprotected pathways into network systems and computers. In the early days of the Internet, many computer systems had limited security, making it possible for a hacker to find a pathway into the system without a username or password. Another way a hacker might gain backdoor access is to infect a computer or system with a Trojan horse.
*Create zombie computers: A zombie computer, or bot, is a computer that a hacker can use to send spam or commit Distributed Denial of Service (DDoS) attacks. After a victim executes seemingly innocent code, a connection opens between his computer and the hacker's system. The hacker can secretly control the victim's computer, using it to commit crimes or spread spam.
*Spy on e-mail: Hackers have created code that lets them intercept and read e-mail messages -- the Internet's equivalent to wiretapping. Today, most e-mail programs use encryption formulas so complex that even if a hacker intercepts the message, he won't be able to read it.

Hacker Hierarchy
Psychologist Marc Rogers says there are several subgroups of hackers -- newbies, cyberpunks, coders and cyber terrorists. Newbies are hackers who have access to hacking tools but aren't really aware of how computers and programs work. Cyberpunks are savvier and are less likely to get caught than a newbie while hacking a system, but they have a tendency to boast about their accomplishments. Coders write the programs other hackers use to infiltrate and navigate computer systems. A cyber terrorist is a professional hacker who infiltrates systems for profit -- he might sabotage a company or raid a corporation's databases for proprietary information [source: Knittel and Soto]



Hackers Culture

Individually, many hackers are antisocial. Their intense interest in computers and programming can become a communication barrier. Left to his or her own devices, a hacker can spend hours working on a computer program while neglecting everything else.

Computer networks gave hackers a way to associate with other people with their same interests. Before the Internet became easily accessible, hackers would set up and visit bulletin board systems (BBS). A hacker could host a bulletin board system on his or her computer and let people dial into the system to send messages, share information, play games and download programs. As hackers found one another, information exchanges increased dramatically.

Some hackers posted their accomplishments on a BBS, boasting about infiltrating secure systems. Often they would upload a document from their victims' databases to prove their claims. By the early 1990s, law enforcement officials considered hackers an enormous security threat. There seemed to be hundreds of people who could hack into the world's most secure systems at will [source: Sterling].

There are many Web sites dedicated to hacking. The hacker journal "2600: The Hacker Quarterly" has its own site, complete with a live broadcast section dedicated to hacker topics. The print version is still available on newsstands. Web sites like Hacker.org promote learning and include puzzles and competitions for hackers to test their skills.

Super Phreak
Before computer hackers, curious and clever individuals found ways to manipulate the phone system in a phenomenon called phreaking. Through phreaking, these individuals found ways to make long distance calls for free or sometimes just played pranks on other telephone users.



When caught -- either by law enforcement or corporations -- some hackers admit that they could have caused massive problems. Most hackers don't want to cause trouble; instead, they hack into systems just because they wanted to know how the systems work. To a hacker, a secure system is like Mt. Everest -- he or she infiltrates it for the sheer challenge. In the United States, a hacker can get into trouble for just entering a system. The Computer Fraud and Abuse Act outlaws unauthorized access to computer systems [source: Hacking Laws].

Not all hackers try to explore forbidden computer systems. Some use their talents and knowledge to create better software and security measures. In fact, many hackers who once used their skills to break into systems now put that knowledge and ingenuity to use by creating more comprehensive security measures. In a way, the Internet is a battleground between different kinds of hackers -- the bad guys, or black hats, who try to infiltrate systems or spread viruses, and the good guys, or white hats, who bolster security systems and develop powerful virus protection software.



Hackers work together to create "mashups" of
Yahoo applications at Yahoo Hack Day 2006.

Hackers on both sides overwhelmingly support open source software, programs in which the source code is available for anyone to study, copy, distribute and modify. With open source software, hackers can learn from other hackers' experiences and help make programs work better than they did before. Programs might range from simple applications to complex operating systems like Linux.

There are several annual hacker events, most of which promote responsible behavior. A yearly convention in Las Vegas called DEFCON sees thousands of attendees gather to exchange programs, compete in contests, participate in panel discussions about hacking and computer development and generally promote the pursuit of satisfying curiosity. A similar event called the Chaos Communication Camp combines low-tech living arrangements -- most attendees stay in tents -- and high-tech conversation and activities.

Hackers and the Law

In general, most governments aren't too crazy about hackers. Hackers' ability to slip in and out of computers undetected, stealing classified information when it amuses them, is enough to give a government official a nightmare. Secret information, or intelligence, is incredibly important. Many government agents won't take the time to differentiate between a curious hacker who wants to test his skills on an advanced security system and a spy.

Laws reflect this attitude. In the United States, there are several laws forbidding the practice of hacking. Some, like 18 U.S.C. § 1029, concentrate on the creation, distribution and use of codes and devices that give hackers unauthorized access to computer systems. The language of the law only specifies using or creating such a device with the intent to defraud, so an accused hacker could argue he just used the devices to learn how security systems worked.



Concern about hackers reaches up to the highest levels of
government. Here, former Attorney General
Janet Reno testifies about hacker activity.

Another important law is 18 U.S.C. § 1030, part of which forbids unauthorized access to government computers. Even if a hacker just wants to get into the system, he or she could be breaking the law and be punished for accessing a nonpublic government computer [Source: U.S. Department of Justice].

Punishments range from hefty fines to jail time. Minor offenses may earn a hacker as little as six months' probation, while other offenses can result in a maximum sentence of 20 years in jail. One formula on the Department of Justice's Web page factors in the financial damage a hacker causes, added to the number of his victims to determine an appropriate punishment [Source: U.S. Department of Justice].

Other countries have similar laws, some much more vague than legislation in the U.S. A recent German law forbids possession of "hacker tools." Critics say that the law is too broad and that many legitimate applications fall under its vague definition of hacker tools. Some point out that under this legislation, companies would be breaking the law if they hired hackers to look for flaws in their security systems [source: IDG News Service].

Hackers can commit crimes in one country while sitting comfortably in front of their computers on the other side of the world. Therefore, prosecuting a hacker is a complicated process. Law enforcement officials have to petition countries to extradite suspects in order to hold a trial, and this process can take years. One famous case is the United States' indictment of hacker Gary McKinnon. Since 2002, McKinnon fought extradition charges to the U.S. for hacking into the Department of Defense and NASA computer systems. McKinnon, who hacked from the United Kingdom, defended himself by claiming that he merely pointed out flaws in important security systems. In April 2007, his battle against extradition came to an end when the British courts denied his appeal [Source: BBC News].

Hacking a Living
Hackers who obey the law can make a good living. Several companies hire hackers to test their security systems for flaws. Hackers can also make their fortunes by creating useful programs and applications, like Stanford University students Larry Page and Sergey Brin. Page and Brin worked together to create a search engine they eventually named Google. Today, they are tied for 26th place on Forbes' list of the world's most wealthy billionaires [source: Forbes].



Famous Hackers

Steve Jobs and Steve Wozniak, founders of Apple Computers, are both hackers. Some of their early exploits even resemble the questionable activities of some malicious hackers. However, both Jobs and Wozniak outgrew their malicious behavior and began concentrating on creating computer hardware and software. Their efforts helped usher in the age of the personal computer -- before Apple, computer systems remained the property of large corporations, too expensive and cumbersome for average consumers.



Steve Jobs, co-founder of
Apple and pioneer hacker

Linus Torvalds, creator of Linux, is another famous honest hacker. His open source operating system is very popular with other hackers. He has helped promote the concept of open source software, showing that when you open information up to everyone, you can reap amazing benefits.

Richard Stallman, also known as "rms," founded the GNU Project, a free operating system. He promotes the concept of free software and computer access. He works with organizations like the Free Software Foundation and opposes policies like Digital Rights Management.

On the other end of the spectrum are the black hats of the hacking world. At the age of 16, Jonathan James became the first juvenile hacker to get sent to prison. He committed computer intrusions on some very high-profile victims, including NASA and a Defense Threat Reduction Agency server. Online, Jonathan used the nickname (called a handle) "c0mrade." Originally sentenced to house arrest, James was sent to prison when he violated parole.



Hacker Kevin Mitnick, newly released from the Federal
Correctional Institution in Lompoc, California.

Kevin Mitnick gained notoriety in the 1980s as a hacker who allegedly broke into the North American Aerospace Defense Command (NORAD) when he was 17 years old. Mitnick's reputation seemed to grow with every retelling of his exploits, eventually leading to the rumor that Mitnick had made the FBI's Most Wanted list. In reality, Mitnick was arrested several times for hacking into secure systems, usually to gain access to powerful computer software.

Kevin Poulsen, or Dark Dante, specialized in hacking phone systems. He's famous for hacking the phones of a radio station called KIIS-FM. Poulsen's hack allowed only calls originating from his house to make it through to the station, allowing him to win in various radio contests. Since then, he has turned over a new leaf, and now he's famous for being a senior editor at Wired magazine.

Adrian Lamo hacked into computer systems using computers at libraries and Internet cafes. He would explore high-profile systems for security flaws, exploit the flaws to hack into the system, and then send a message to the corresponding company, letting them know about the security flaw. Unfortunately for Lamo, he was doing this on his own time rather than as a paid consultant -- his activities were illegal. He also snooped around a lot, reading sensitive information and giving himself access to confidential material. He was caught after breaking into the computer system belonging to the New York Times.

It's likely that there are thousands of hackers active online today, but an accurate count is impossible. Many hackers don't really know what they are doing -- they're just using dangerous tools they don't completely understand. Others know what they're doing so well that they can slip in and out of systems without anyone ever knowing.

In Side Google Office/ Google's Intranet

Have a Look in Google Office/ Google's Intranet


What do around 16,000 Google employees stare at in the morning when they’ve arrived at the office? They might be looking at Moma, the name for the Google intranet. The meaning of the name of “Moma” is a mystery even to some of the employees working on it, we heard, but Moma’s mission is prominently displayed on its footer: “Organize Google’s information and make it accessible and useful to Googlers.” A “Googler,” as you may know, is what Google employees call themselves (they have other nicknames for specific roles; a noogler is a new Google employee, a gaygler is a gay one, a xoogler is an ex-one, and so on).


A Google employee in Hamburg (photo taken in mid-2007)

Moma “was designed by and for engineers and for the first couple of years, its home page was devoid of any aesthetic enhancements that didn’t serve to provide information essential to the operation of Google. It was dense and messy and full of numbers that were hard to parse for the uninitiated, but high in nutritional value for the data hungry.

Here’s a picture of the Moma homepage that we got hold of – please note that large areas have been grayed out or whitened out:



On the top of the Google intranet homepage, you’ll find the logo reading “Moma - Inside Google.” Next to it is a search box allowing you to find information from Moma in general, information on specific Google employees, information on availability of meeting rooms, building maps and more. You can choose to include secure content or not via a checkbox. Another checkbox offers you to use “Moma NEXT" for a more experimental variant of search results.

To the top right, there’s an option to switch to iMoma, an iGoogle-style tool prepared by the company which allows further customization of the intranet start page. This way, employees may be able to select their own news and service widgets of interest to be displayed when they log-in.

The actual content of the homepage in the picture is split up into 4 columns. To the left, there’s a “My Office” section, with information for employees and a way to choose your own office for more relevant links. It’s followed by the sections “Survival Kit” and “My shortcuts.” In the middle columns, news gadgets are headlined “Welcome to Google!,” “Communications,” “HR” (human resources), “Company Info” and “Internal Google news,” all in common soft shades of Google base colors. The right column is listing Google teams.

Searching Moma

When you perform a search on Moma, you will see a result similar to the following; this screenshot, which was edited by Google to include comments, has been published by the Google Enterprise Blog in a post of theirs in July to show-case the kind of functionality available:



On the image, you will see a “universal search" style result including employee information, bookmark results, documents hosted on Google’s intranet, and a list of related queries. Users get to choose between ordering by date or by relevance. One can also limit the results to different segments like “Tech,” “Official,” or “Community.” Google in their blog said the use the Google Search Appliance to power this service.

Ex-employee Doug Edwards mentioned how he came to take for granted everything was available on the intranet, “from the status of products in development to the number of employees at any point in the company’s history.” He adds that the transparency was also a motivator, as “Your failures are also visible to everyone in the company, which provides an even greater motivator to continuously improve performance in the areas for which you are responsible.” These days however, as Doug writes, Google “clamped down on who had access the complete state of the business.

The following photo shows a result for what seems to be an employee search. The photo is used with permission from Zach at HannaCabana.com, though Zach tells me it had been anonymously submitted to him (note we added blurring to the phone numbers of the zoom version):



On the employee results page, everyone is listed with their name, a photo, their job title, telephone number and more. Clicking through to an employee lands you on their full profile page. Ex-Googler Doug Edwards remembers how many Google employees used “alternative images and titles" for their Moma listing. “I recall photos of samurai warriors and masked figures with titles like ’Shadow Ops’ and ’Black Ops.’ These were later weeded out as part of an upgrade”.

Employee data may also be rendered in different forms. Below is a screenshot we first posted on in February of an internal application called Google Percent:



This service simply shows how many employees are newer than a particular other employee (some areas in the image have been blackened out).

How employees access the intranet

Photo courtesy of Zach, again.

The dialog reads, “Many internal apps. One login page.” The input boxes ask for the user’s LDAP (Lightweight Directory Access Protocol) credentials.

A Google employee can log-in to the intranet from within the office, or with a so-called Virtual Private Network (VPN) connection. This connection comes pre-installed on laptops Google hands out, and can be reached via a desktop icon. A Google employee is required to authenticate their sign-in with account credentials.

From within a Google building, an employee may likely reach the intranet via the address corp.google.com. We previously found out Google additionally uses many sub-domains in their intranet, like album.corp.google.com, agency.corp.google.com, alien.corp.google.com, karma.corp.google.com, periscope.corp.google.com, pineapple.corp.google.com. You may also likely just enter e.g. “m” (which maps to “http://m” which is “http://m.corp.google.com”) to be taken to a service like your Gmail-powered email account.

Externally, like from a laptop at a conference – or if you’re one of the employees mainly working from home, as there are some – employees can access the VPN servers located on sites like Mountain View or Dublin, Ireland, with different hostnames each like man....ext.google.com or de....ext.google.com (we depleted part of the hostname).

Google “eating their own dog food”

Google employees use many of the tools Google produces. They even have launched an internal “dogfood” campaign in 2006. But what they see may be newer versions of the services than those released to the outside.


Andrew Hitchcock

from July, Creative Commons-licensed(edited for brightness/ contrast).

If you work in a team for a product, you may also get a prototypical version of the service. Below for instance is a screenshot from a nightly build of Google Spreadsheets – codename “Trix” – which we were able to take a look at (note several areas in this image have been grayed out):



In above image you can see the disclaimer “Warning: This is NOT production. Data can be lost.” Special links to debug windows are offered to developers as well, one of them being opened in the screenshot. Google employees also get to see previews of completely unreleased tools, such as wiki service JotSpot (which is being integrated into Google Apps), or Platypus, the internal Gdrive client for file-sharing.

For code reviews, Google created Mondrian, a “Perforce backend with some custom Google wrappers on top,” as Nial Kennedy, who shot the following photo Creative Commons-licensed, notes:



And the following image shows Google in-house tool Trax (this is part of a larger photo by Google employee Andrew from Flickr, but it is not available anymore; we’re not quite sure how this tool works or what it achieves):



But, Google doesn’t just use their own tools. For instance, we came across information indicating that many Google employees prefer social network Facebook.com to their own production, Orkut (e.g. some Google employees considered Orkut too spammy, or too buggy in the past).

If a Google employee encounters trouble with any Google tool, they can call their internal support hotline named “Tech Stop.” The hotline promises 24-hour availability. Numbers like +1 877... (last part depleted) are partly toll-free and partly with toll, and accessible from all over the world. Internally, a Google employee may also simply press 3-HELP (3-4357). Tech Stop centers aren’t just located in the US, but also in places like Hyderabad, India.
