Web Spoofing - Arts of Attack and Defense
Spoofing means pretending to be something you are not. Some potential spoof attacks are web spoofing ppt able designs difficult. These are more difficult to prevent because users do not necessarily have the technical subtlety needed to understand what is happening, whilst the technology they use does not explain itself very clearly in non-technical terms.
In this white paper, several web spoofing ppt able designs attacks, and possible defenses against them are considered. The URL that an Internet user types in is not the numeric address of the site required, but an alphanumeric address structure. The DNS servers convert, say, www.
An attack of this type has been successfully mounted that altered the server list, so that, for a period of time, users requesting some sites were directed to the wrong addresses. This type of attack is a major threat and the Internet naming and addressing authorities have taken it very seriously indeed. This kind of problem can be resolved by positive site identification, where the end user is able to automatically check the claimed web site URL against the content provided, as provided by the ArticSoft approach.
There web spoofing ppt able designs many ways in which a web site may be spoofed. A copy of a site can be created sathrapathi tamil songs the original by copying all the publicly accessible pages from a site to another server.
Some spider activities are legitimate - maintaining mirror copies of the site to improve accessibility, or search engines looking for text and keywords to add to their catalogues.
Other spider activities may not be. The technical defenses against this attack are few. Sometimes the copying may be to present your information as that of another site. A number of schemes for 'watermarking'images have been invented in recent years to help detect this kind of attack, and an excellent reference is http: The simplest spoof is web spoofing ppt able designs catch the people who mistype the web URL they are looking for, or put the wrong locator at the end.
Sometimes the content makes it obvious to the user that the site is not the one they were expecting, but it doesn't have to. Shown in a different font this is www. For an excellent tutorial on how to carry out this kind of attack and the uses it can be put to see the web site www. The most effective defense against this kind of confusion is probably procedural. Altering the registration rules for Internet names to prevent registering names that are very close to those of registered companies or organizations could well help prevent this problem.
Usually national laws prevent people from registering company names that are similar to existing ones for exactly this reason there is, in some jurisdictions, the offence of passing offso the justification for allowing it on the Internet is muddy at best.
Selling domain names is a business whilst registering a company is something controlled by law. As a result, there may be differences in approach. Law evolved to make company registration a formal process for good reasons that the Internet does not appear to have fully recognized.
Another attack, that offers far more gain to the hacker for rather less actual work, is to alter the return address in a web page sent to a user to make it go to the hacker's site rather than the legitimate site. This is done by adding the hacker's address before the actual address in any page that has a request going back to the original site. You will notice that the fake site is recognized as a valid URL address. The hacker only need to do this once to get a link into the communication between browser and server and they can reprocess all the communication from then on, including SSL connections.
The commonest form of defense used by web sites at the moment is to apply 'digital signatures'to their web pages, which are checked as they are leaving the server to ensure that nothing has been changed. The idea is to prevent altered pages from being able to enter the Internet.
Recent developments by ArticSoft have produced a system that provides end users with continual verification of pages back to site URLs. This latter feature is possible because most sessions do not, or cannot verify the user identity to the server, and the user does not know what identity the SSL connection should have. SSL is a technology that has succeeded largely because few users understand it or the padlock on the browser at all. An SSL link for commercial sites is started by the browser, without validating where it is linking to.
A variety of academic papers have been published detailing attacks that defeat SSL and demolish many of the claims made for its capabilities have been published. User lack of understanding is further web spoofing ppt able designs by techniques that are common industry practices which confuse security.
ISP certificates are often used as the common certificate for all their hosted web sites. The use of third party secure services for payments systems with completely different site names also confuses the situation. Users can hardly be expected to understand what to them are arcane practices that have no apparent explanation. On balance, it is just as well that the end user remains blissfully ignorant.
However, this is the very ignorance that fosters hacking and spoofing. Changing this situation is not a matter of expecting all users to become expert technologists. Education is required, but so are appropriate methods of development behaviour that increase understanding and security as principles and best practice. Hackers are able to configure themselves their messages over the Internet to have any IP address that they want, so they can appear to be part of an internal network when in fact they are external, or appear to be the address that you want to connect to.
Many networks are set up to dynamically allocate addresses, and software monitoring techniques to reveal information flowing around networks allow hackers to select valid addresses so that they can impersonate valid sessions. Alternatively, the hacker may try to capture a valid available address. Defenses against this kind of attack are often firewall based. To guard against this situation some organizations, particularly financial ones, use internal firewalls to control and limit the potential for this kind of attack.
In particular services, such as e-mail, the potential to gratis nederlandse sites the apparent source address continues to be a problem. Most users are unaware that the apparent address is unreliable, and that replying to the apparent address may actually send a message to an unintended destination.
The reply goes to the group, not the individual who appeared to be the source. E-mail with secure attachments may be prone to spoofing as well. Spoofing attacks are based upon the ability to make raoul n-ai sa stii zippy smiley user believe that they are securely connected to a network address, or receiving e-mail from a specific source, when that is not the case. Since there are currently no effective means of securing the addressing unless everyone 'knows'everyone else, the attempts to secure links between address points are flawed, and unless there is a move to mandate absolute identification of all Internet users politically unlikely given requirements for anonymity that exist in US law for certain types of transactions they will remain so.
A change is needed to move from relying on networking systems that don't solve the problem to content management - signing and protecting the web spoofing ppt able designs information itself web spoofing ppt able designs not just the unproven link s it is traveling over. A change to securing content, rather than links, offers the e-business community significant benefits. For e-business, there is web spoofing ppt able designs imperative for the honest trader to identify themselves by clearly identifying their content.
By switching to that approach, the business community can achieve major trading benefits: Conversely, traders not following such an approach identify themselves as leaving their customers open to fraud, misrepresentation, uncertainty and lack of confidence.
ArticSoft have provided some novel steps in the direction of proof by content rather than proof by network connection. For Internet technologies this is a more pragmatic way to proceed because content may reside anywhere on the Internet. Such a change faces significant opposition, not least from the network providers, network analysts and managers, who risk being relegated to a lower status and relative income as a web spoofing ppt able designs.

Link alteration Another attack, that offers far more gain to the hacker for rather less actual work, is to alter the return address in a web page sent to a user to make it go to the hacker's site rather than the legitimate site. IP addresses changing attacks Hackers are able to configure themselves their messages over the Internet to have any IP address that they want, so they can appear to be part of an internal network when in fact they are external, or appear to be the address that you want to connect to.
E-mail address changing In particular services, such as e-mail, the potential to spoof the apparent source address continues to be a problem. Review of the current situation Spoofing attacks are based upon the ability to make a user believe that they are securely connected to a network address, or receiving e-mail from a specific source, when that is not the case.

W e're high up in the Gherkin in the City of London and Garry Sidaway, director of security strategy at Integralis, a firm which advises government agencies, pharmaceutical and financial services multinationals, is giving my computer a security MOT. According to Sidaway, while most of us are much more aware of the risks now "My mum shreds her documents even if she doesn't know why," he sayswe should all be raising the bar. He thinks we Britons are an overly trusting lot.
Sitting ducks for an armada of hackers, who are every bit as focused on stealing our data as we are relaxed about storing it. So what are they after, Web spoofing ppt able designs ask?
Enabled by the sharing culture on social media — and with ever more sophisticated malicious software known as malware at their disposal — cybercriminals have become far more adept at crafting web spoofing ppt able designs and targeting individuals and organisations.
A recent example of the latter was malware disguised as a security warning from Microsoft's digital crimes unit. Typically, these so-called web spoofing ppt able designs attacks install colourfully named Trojans pieces of malware, essentially such as Zeus, SpyEye or Citadel on computers, which have the effect of compromising, for example, online banking transactions.
Initially, man-in-the-middle attacks were passwords used in authentication — the criminal would wait until you had finished to start using the credentials they'd just gathered. This is why banks brought in one-time passwords or codes," web spoofing ppt able designs says. Once the user thinks they've logged out, the attacker can make payments using the existing session without the victim seeing any changes to their balance until the next time they log on.
This is partly why banks have rolled out card readers to help prevent payments to new payees. Never click on a link you did not expect to receive The golden rule. The main way criminals infect PCs with malware is by luring users to click on a link or open an attachment.
Use different passwords on different sites With individuals typically having anything up to online accounts, the tendency has become to share one or two passwords across accounts or use very simple ones, such as loved ones' names, first pets or favourite sports teams. Any word found in the dictionary is easily crackable. Instead, says Sian John, online security consultant at Symantec, have one memorable phrase or a line from a favourite song or poem.
For example: Add numerals and a special character thus: Now for every site you log on to, add the first and last letter of that site to the web spoofing ppt able designs and end of the phrase, so the password for Amazon would be "AT0! At first glance, unguessable. But for you, still memorable. Never reuse your main email password A hacker who has cracked your main email password has the keys to your [virtual] kingdom. Passwords from the other sites you visit can be reset via your main email account.
A criminal can trawl through your emails and find a treasure trove of personal data: Use anti-virus software German security institute AV-Test found that in there were 49m new pun pariu ca ma iubesti fisierul meu of malware, meaning that anti-virus software manufacturers are engaged in constant game of arthimoth mp3 s. Much like flu viruses and vaccine design, it takes the software designers a while to catch up with the hackers.
Last year AV-Test published the results of a month study of 27 different anti-virus suites and top-scoring packages were BitdefenderKaspersky and F-Secure.
If in doubt, block Just say no to social media invitations such as Facebook-friend or LinkedIn connection requests from people you don't know.
It's the cyber equivalent of inviting the twitchy guy who looks at you at the bus stop into your home. Think before you tweet and how you share information Again, the principal risk is ID fraud. Trawling for personal details is the modern day equivalent of "dumpster-diving", in which strong-stomached thieves would trawl through bins searching for personal documents, says Symantec's John. Once that information is out there, you don't necessarily have control of how other people use it.
If you web spoofing ppt able designs a "wipe your phone" feature, you should set it up Features such as Find My iPhone, Android Lost or BlackBerry Protect allow you to remotely to erase all your personal data, should php fusion v778 device be lost or stolen. Even if you didn't have the foresight to sign up, many wipe your phone features can be implemented after the fact. Only shop online on secure sites Before entering your card details, always ensure that the locked padlock or unbroken key symbol is showing in your browser, cautions industry advisory body Financial Fraud Action UK.
Additionally the beginning of the online retailer's internet address will change from "http" to "https" to indicate a connection is secure. Be wary of sites that change back to http once you've logged on.
Banks must refund a customer if he or she has been the victim of fraud, unless they can prove that the customer has acted "fraudulently" or been "grossly negligent". Yet as with any case of fraud, the matter is always determined on an individual basis. Under payment services regulations, the onus is on the payment-service provider to prove that the customer was negligent, not vice versa.
Credit card protection is provided web spoofing ppt able designs the Consumer Credit Act and offers similar protection. Ignore pop-ups Pop-ups can contain malicious software which can trick a user into verifying something.
Always ignore pop-ups offering things like site surveys on hp 4730mfp manual sites, as they are sometimes where the malcode is. Be wary of public Wi-Fi Most Wi-Fi hotspots do not encrypt information and once a piece of data leaves your device headed web spoofing ppt able designs a web destination, it is "in the clear" as it transfers through the air on the wireless network, says Symantec's Sian John.
If you choose to bank online on public Wi-Fi, that's very sensitive data you are transferring. We advise either using encryption [software], or only using public Wi-Fi for data which you're happy to be public — and that shouldn't include social network passwords.
Thinking about having one for your bank and other financial accounts, another for shopping and one for social networks. If one account is hacked, you won't find everything compromised. And it helps you spot phishing emails, because if an email appears in your shopping account purporting to come from your bank, for example, you'll immediately know it's a fake. It's true that Macs used to be less of a target, simply because criminals used to go after the largest number of users — ie Windows — but this is changing.
Don't store your card details on websites Err on the side of caution when asked if you want to store your credit card details for future use. Mass data security breaches where credit card details are stolen en masse aren't common, but why take the risk? The extra 90 seconds it takes to key in your details each time is a small price to pay. Add a DNS service to protect other devices A DNS or domain name system service converts a web address a series of letters into a machine-readable IP address a series of numbers.
But they shouldn't be relied upon as the only line of defence, as they can easily be bypassed. Enable two-step verification If your email or cloud service offers it — Gmail, Dropbox, Apple and Facebook do — take the trouble to set this up. In addition to entering your password, you are also asked to enter a verification code sent via SMS to your phone. In the case of Gmail you only have to enter a fresh code every 30 days or when you log on from a different computer or device. So a hacker might crack your password, but without the unique and temporary verification code should not be able to access your account.
Lock your phone and tablet devices Keep it locked, just as you would your front door. Keying in a password or code plus times a day might seem like a hassle but, says Lookout's Derek Halliday, "It's your first line of defence. Be careful on auction sites On these sites in particular, says Symantec's Sian John, exercise vigilance.
Facebook regularly updates its timeline and privacy settings, so it is wise to monitor your profile, particularly if the design of Facebook has changed. Firstly, in the privacy settings menu, under "who can see my stuff? Also in privacy, setting "limit old posts" applies friends-only sharing to past as well as future posts. Web spoofing ppt able designs, disable the ability of other search engines to link to your timeline.
You should also review the activity log, which shows your entire history of posts and allows you to check who can see them. Similarly, you should look at your photo albums and check you're happy with the sharing settings for each album. In the future you may want to consider building "lists" — subsets of friends, such as close friends and family, who you might want to share toddler photographs with, rather than every Tom, Dick and Harriet.
Also, remove your home address, phone number, date of birth and any other information that could used to fake your identity. Similarly you might web spoofing ppt able designs to delete or edit your "likes" and "groups" — the more hackers know about you, the more convincing a phishing email they can spam you with. Facebook apps often web spoofing ppt able designs your data, so delete any web spoofing ppt able designs don't use or don't remember installing. Finally, use the "view as" tool to check what the public or even a particular individual can see on your profile, continue to "edit" and adjust to taste.
If this all sounds rather tedious, you just might prefer to permanently delete your account. Remember you're human after all While much of the above are technical solutions to prevent you being hacked and scammed, hacking done well is really the skill of tricking human beings, not computers, by preying on their gullibility, taking advantage of our trust, greed or altruistic impulses.
Human error is still the most likely reason why you'll get hacked. This article contains affiliate links, which means we may earn a small commission if a reader clicks through and makes a purchase.
