Bob squinted at the email and began to read:
“Dear eBay User, as part of our security measures, eBay Inc. has developed a security program against fraudulent attempts and account thefts. Therefore, our system requires further account verification…”
Security Measures. A threat to suspend his account to prevent “fraudulent activity”. The email went on to say that there were “procedural safeguards with federal regulations to protect the information you provide for us.”
Bob clicked the link and was confronted with an authentic looking logon page, just waiting for him to input his user name and password and confirm what ebay supposedly didn’t know.
He almost did it. The page looked absolutely authentic, and he had already been “set up” by the email message. His fingers were poised over the keyboard when he happened to glance at the URL.
There was something very, very wrong with it.
“PHARMING” TO FLEECE SHEEP
The art of “pharming” involves setting up an illegitimate website that is identical with its legitimate prototype, for example the ebay page Bob was almost suckered into using, and redirecting traffic to it.
“Pharmers” can do it in two ways:
1.By altering the “Hosts” file on your computer. The Hosts file stores the IP address of websites you have been accessing. By inserting a new IP address into the database field corresponding to a website, your own computer can be redirected to the pharmer’s website. Any information you give the bogus site is immediately hijacked by the pharmer.
2.Hijacking the DNS (Dynamic Name Server) itself. A DNS matches the names of address with their IP addresses. If this server can be coerced into assigning new IP addresses to traditional names, all computers using the name resolution provided by the DNS server will be redirected to the hijacker’s web site.
Once that happens, it’s time to be fleeced.
DOWN ON THE PHARM
“Pharmers” hijack your “hosts” file or DNS servers using Spyware, Adware, Viruses or Trojans. One of the most dangerous things you can do is to run your computer without some form of Internet Security installed on it.
Your security software should be continually updating its virus definitions, and be capable of warning you if something has been downloaded from a web site or through email. It should be able to remove it, “quarantine it”, or tell you where it is so that you can remove it by hand.
You should also have Spyware and Adware programs installed, and be aware of any change in Internet browsing patterns. If your home page suddenly changes, or you experience advertising pop ups (which may pop up even when you are not hooked up to the Internet), you should run a Virus, Spyware or Adware scan.
Thanks to the efficacy of these protection programs, pharming is a lot more difficult than it used to be. It isn’t as easy to hijack a computer as it once was.
So, the “pharmers” have teamed up with the “phishermen” to get you to visit the bogus web page yourself, and enter all the information they need.
PHISHING TO CATCH YOU ON THE PHARM
As Bob discovered, the page he had been taken to by the bogus email message was identical to the ebay logon page. Identical in every way except for the URL.
Out of curiosity, he checked the URL for the ebay logon by accessing ebay directly and clicking on the logon link. The two URL’s were nothing alike, except the bogus one did have the word “ebay” in it twice – just enough to make it look authentic.
By combining the two techniques, the phishermen/pharmers had avoided the high tech problems associated with downloading a Virus that could get past his protection software. They had gone straight for the throat.
Bob’s throat.
YOUR ONLY REAL IDENTITY THEFT PREVENTION AND PROTECTION
The only real protection against the pharmers and phishermen is YOU. There are three things you must consider when you read any email demanding information:
