Phishing: Examples and its prevention methods

Posted by admin on Tuesday, June 23, 2009

Phishing is the criminally fraudulent process of attempting to acquire sensitive information such as usernames, passwords and credit card details by concealing as a trustworthy entity in an electronic communication.



It is usually done by sending fake emails and redirecting unsuspecting users by using fake websites which the URL will use legitimate form like email address, logos and link of reputable business such as SunTrust, eBay, Citibank, Chapter One Bank, PayPal and IRS Tax Refund in the message.



The examples of phishing scam are as follows:

Ebay


Trusted Bank


Citibank

The ways to prevent phishing scam:

  1. Check where the email comes from
    • Checking the sender of the email. If the email address is not the domain of a legitimate bank/service, then it is certainly a phishing scam

  2. Do not follow a “click here” link in the email
    • The email will contain the link which named as “Click here” or link which may re-enter to your user information. Please measure whether the link is meeting to the legitimate website or content before you click on it.

  3. Check contact information provided in the email
    • Double check the contact information by using your recorded contact information such as phone number, fax number and address of that company to the email.

  4. Check your personal information that provided in the email
    • You can check out the information that stated in the email by figuring out whether it suits your original information such as when you register for this website or account.

  5. Make sure a site's URL as listed in the browser is legitimate
    • Verify the legitimacy of a web address with the company directly.

  6. Avoid filling out forms in e-mail messages

    Revenue Model of Google, Amazon.com and eBay

    Posted by admin on Saturday, June 20, 2009


    Google is globally well known for its search engine. It provides high level of services to all users who seek information and resources. Besides global Internet search solution, Google also offers targeted advertising solution. This is the revenue model of Google.



    AdWords
    Google generates most of its revenue from Google AdWords. It is a pay per click advertising program of Google designed to allow the advertisers to present advertisements to people at the instant the people are looking for information related to what the advertiser has to offer. The advertisements are usually placed on the right side of the screen or sometimes above the main search results. The advertisers need to pay for their advertisements once the Google users click on it.


    AdSense

    AdSense is another advertisement application run by Google. Website owner can enroll in this program to enable text, image and video advertisement on the Google’s search result pages. Google generates revenue on either a per-click or per-impression basis. When a visitor clicks one of the advertisements, the AdSense publisher will share the cost-per-click advertisement revenue with Google.



    Amazon.com is known as the America’s largest online retailer. It started as an online bookstore but soon diversified to product line of computer software, music DVDs, video games, electronics, and so on. Therefore, it is clear that Amazon.com generates the revenue through sales.

    Besides that, Amazon.com also generates revenue by transaction fees and affiliate fees. Amazon.com will charge transaction fees on the sales and also affiliate fees on those who advertise in the Amazon website.




    eBay is an online auction and shopping website in which people and businesses buy and sell a board variety of goods and services worldwide. Besides that, eBay also owns PayPal and Skype.

    eBay is very similar to Amazon.com. Both are using sales and transaction revenue model. eBay will gain revenue for every successful transaction. Besides that, PayPal can earn revenue through online payment. PayPal has gained users trust worldwide and has become a global leader in online payment solution.

    A review on Real-World Case: Google is changing everything

    Posted by admin on Thursday, June 18, 2009

    Assignment! Assignment!
    Actually most of the UTAR students always useGoogle” as the main search engine to find the information in order to complete their assignment. This is because Google co-founder Larry Page says that “Google search engine would understand exactly what you mean and give back exactly what you want.”

    Nowadays, Google has become the big dog of search engines and successfully concerns the market on popularity among internet users. Although Google may be the favorite search engine by users, it is always aware that a “king” position can be deposed. As we know that “Microsoft” is a powerful and potential competitor against Google and thus as a result, Google is changing everything in order to achieve their organization’s goals.


    Given the state of Google’s technology today, Google’s goal is to provide a much higher level of service to all those who seek information and resources. Besides that, Google’s mission is to organize the world’s information and make it universally accessible and useful. Google’s vision is requiring more research, development and innovation to realize.


    A glimpse at Google’s activities such as their own products, technology, and the Google culture, some innovative changing will be discovered.



    Besides the Google Spreadsheet products, Google has introduced a new Web Browser which is called Google Chrome, aimed at wresting dominance of the browser market from Microsoft’s Internet Explorer. The function of Chrome browser is more effective and efficient than Microsoft’s Internet Explorer, Mozilla’s Firefox and Apple’s Safari. I believe that if Google succeeds, it will be a big challenge with major ramifications for the future of the Web.

    Google Chrome Icon Project

    According to “Personal Technology” from The Wall Street Journal, the author who is Walter S. Mossberg stated the reasons of why Google ignites the new browser war. The reasons actually involve competing with Microsoft. There are two reasons.

    First, Google is in fear that its search engine and other major products will depend on the Microsoft’s browser because it might be able to gain an advantage by altering the design of Internet Explorer, which has roughly 75% market share.



    Second, Chrome was designed to be the world’s speediest browser at handling JavaScript. This is because Google sees the Web as a platform for the software programs or web applications that it is currently running directly on computer operating systems, notably Microsoft’s Windows. Moreover, current browsers lack the underlying architecture but more powerful web applications that will rely more greatly on a common Web programming language which called JavaScript. That is why Google would like to create a new browser.




    In conclusion, I agree that “Google is changing everything” because Google has persistently pursued innovation and pushed the limits of existing technology to provide a fast, accurate and easy-to-use search service or search engine in real world.




    INFORMATION SHARING - Google’s software:

    Picasa” is a software application for organizing, editing, transferring, finding, printing, and sharing digital photos. Based on my experience, I use Picasa software helps me to manage the photo on my computer because it is the fastest way to categorize all photos. Therefore, the latest version of Picasa 3.1 greatly improves the collage tool and adds a basic movie maker that let me intersperse a wide range of video.
