What is URL Hijacking?

Posted in All Posts, Exploits, Online Security, Scams on November 4th, 2010

Have you heard of URL hijacking?  What is it?  How does it happen?  What are the consequences?

I received a panicked call from one of my customers the other day:  Hey, what’s wrong here?  What happened to Mapquest?

So, I typed in mapquest.com and it came right up.  So I asked, tell me more about what is happening, please tell me step by step what you are doing and what you are seeing.

“Oh, I just typed in mapquest and I am getting this site that looks like mapquest but now they want my phone number and some other info.”

OK, where exactly did you type in mapquest?  In google* by any chance?  Did you put in mapquest.com?

“No, just mapquest.”

So I said, please type in mapquest.com in the address bar in the top of you browser, not in the google* search window.

“Oh, that works!  There it is!  Thanks!”  ”But I did type it into the address bar!”

So, what do you suppose happened here?  How did she get to a web site that was trying to scam her into revealing personal information?

Answer: URL Hijacking.

  1. Her browser was set to search from the address window.
  2. She did not type in the full URL. (or she could have misspelled it slightly)
  3. She clicked on a result that looked like mapquest.
  4. She ended up at a malicious website what was trying to trick her into revealing her identity and probably also attempted to install malware on her computer.

Solution:

  1. Turn off searching from the address bar.
  2. Never look for a known web site by searching for it. If you know the correct URL, type it into the address bar, not into some search engine.
  3. If you do search for a web site, be skeptical and very careful about the results.

* any search engine can lead you to URL Hijacking.  Her browser happened to be set to search from the address bar using google.

The #1 Internet Scam

Posted in Scams on April 20th, 2008

The #1 Internet scam is the known as the Nigerian scam, or the 419 scam.  

This scam weaves a very sad tail of woe,  a tail that is able snare many victims.

These scammers spew out millions of emails promising large amounts of money in return for some kind of specified task, such as helping to transfer a large sum of money left by some dead relative.  But these scam  always require some advance payments from the victim.

These advanced payments are the whole point of these scams.  The scammer promises a share of some large sum of money, while extracting many smaller sums of money from the victim.  The victim never gets any money.  But still, this scam is surprisingly successful.

OK, You Have Heard of Phishing, But What About “Vishing”?

Posted in All Posts, Email Security, Exploits, Scams on January 21st, 2008

By now, lots of folks have become wary of Phishing.  But what about “Vishing”?

Vishing is the practice of using an email or text message to bait a person to call a certain phone number.

The inducement is usually in the form of some dire warning about a problem with your bank or credit card account, and the email instructs you to call the phone number listed in the email.

At the other end, you will find someone, or an automated system, who impersonates your bank or credit card company.  They will request all your account details, and will those details to rip you off.

If you get one of these, DO NOT CALL THE PHONE NUMBER LISTED IN THE EMAIL.

If you do have any concerns about your bank account, call a listed phone number.   Find it on your statement or in the phone book.  Or, if it is about a credit card, call the number listed on the back of your credit card.

 And report the “vishing” attack.  (Just be prepared to explain what a “vishing” attack is.  They may not be familiar with the term.)

Email Addresses Don’t Win Lotteries

Posted in Email Security, Exploits, Scams on July 9th, 2007

Many email inboxes are being flooded with announcements that you have won a lottery. They usually that say something to the effect: your email address was picked at random, and has won a ton of money.

Well, that does not happen. Every last one of these emails is a scam. Period.

To be more exact, many of these are what is called an “advanced fee scam”. If you contact them, they will try to get enough personal information to steal you identity several times over, and secondly, you will be required to advance money in order to “process your winnings” or some such phony excuse.

One of the most certain things in life: You will never see that money again, and you will never get any winnings whatsoever. Period.

Unfortunately, thousands of gullible people fall for these scams ever year, and they loose millions of dollars. Don’t be one of them.

And please also ensure that none of your frends and relatives fall for this scam. Talk about it.

The e-Greeting Card Scams

Posted in Email Security, Exploits, Malware, Scams on June 30th, 2007

An new round of malicious e-greeting card spam is landing in in-boxes. It usually has the subject line “You’ve received a postcard from a family member!”

Whatever you do, do not open these spam emails, and do not click on the links.

If you do, you will be taken to a malicious web site that will attempt to install a variant of the Storm Trojan horse.

    “Today’s greeting-card gambit tries a trio of exploits, moving on to the second if the machine is not vulnerable to the first, then on to the third if necessary. The first is an exploit against a QuickTime vulnerability; the second is an attack on the popular WinZip compression utility; and the third, dubbed “the Hail Mary” by the ISC, is an exploit for the WebViewFolderIcon vulnerability in Windows that Microsoft Corp. patched last October.”

Source: ComputerWorld

This demonstrates the importance of updating all software to the latest versions. In this case, QuickTime WinZip and Windows are the targets. Users who have updated to the latest versions are protected.

And of course, it demonstrates the importance of being suspicious of all email that lands in your inbox.

Posted in All Posts, Email Security, Exploits, Scams on May 21st, 2007

The Finely Tailored Suit, er Email.

Spammers have learned to tailor their scam emails to specific groups of users. These spammers use clever social engineering to ensnare their victims. These emails can be successful in disarming caution in even the most cautions email recipient.

Our advice:

  • Never ever respond to unsolicited email, period.
  • Never ever respond to any email warning of dire consequences unless you respond.
  • Never ever respond to any unsolicited offer for any product, period.
  • Never ever respond to any email that promises great reward if you respond, such as lottery winnings, business relationship offers, etc.
  • Please do understand what an “advanced fee scam” is.
  • And even if you believe the email is solicited, use great caution.
  • Use great caution even if the email appears to be from some organization with which you have a relationship. They can easily be spoofed.
  • If the email has links, we advise that you not use them *especially* if related to any account login. We recommend that you simply go to the web address of the organization in question, by typing their address into the browser address bar, instead of clinking on any link in these emails.
