Help! There's a worm in my end-user license agreement
A new digital pest acts much like the address-book worms of old but with a twist: it asks your permission before hijacking your Outlook contacts. Robert Vamosi predicts that this is a tactic we'll see more of in the future.

Now that most of us know enough not to open unsolicited e-mail attachments, malicious coders are looking for other ways to infect large numbers of computers quickly. A marketing technique used by Panama-based Permissioned Media could provide virus writers with some inspiration.

This company has a crafty scheme: You receive an e-mail message that looks like an electronic greeting card from FriendGreetings.com. The e-mail asks you to download a plug-in in order to view the card. It then presents you with a legitimate end-user license agreement (EULA), which you must accept in order to get the software.

Tactic could be used in viruses
But if you read the fine print, you'll see that the agreement asks for permission to raid your Outlook contact list. If you accept the agreement, Permissioned Media sends a copy of the message to all of your contacts--not unlike mass-mailing e-mail viruses.

If you accept the agreement, Permissioned Media sends a copy of the message to all of your contacts--not unlike mass-mailing e-mail viruses.
While FriendGreeting is not technically a virus, I wouldn't be surprised to see EULAs used by malicious coders in future virus outbreaks because they could protect the virus author from potential legal action.

Just to make sure you don't fall prey to the FriendGreetings scheme, here are more details about how it works. The e-mail is usually sent from someone you know (because your name was in the sender's Outlook contact list). The FriendGreetings card requests that you click a link and download a browser plug-in that will allow you to view the contents of the card.

The link sends you to a site that's a variation on FriendGreetings.com, Cool-Downloads, or Laugh-Mail, according to antivirus company MessageLabs. All of these domain names are registered by Permissioned Media.

Before downloading the plug-in, a security warning pops up stating that the FriendGreetings program is digitally signed and distributed by Permissioned Media. It even says the following: "Permissioned Media Inc. asserts that this content is safe. You should only install/view this content if you trust Permissioned Media Inc. to make that assertion."

Nothing illegal here
This is a standard digital certificate screen, verified by a third-party certificate authority, complete with an option for you to "Always trust content from Permissioned Media Inc." Such certificates commonly appear when you visit enhanced-media HTML sites for the first time or when you download software. Most of us simply accept the certificate and continue with our business.

Be wary the next time you're asked to download a new plug-in for your browser.
If you select Yes on the certificate, the program is downloaded to your hard drive. Then, the familiar InstallShield wizard pops up and automatically displays two standard-looking EULAs. Most of us don't read these lengthy statements and instead simply click the I Accept button to complete the installation. However, in this case, the second agreement clearly states that FriendGreetings will have access to your Outlook client in order to send similar electronic-greeting messages to everyone on your contact list.

Sadly, there's nothing illegal about this, and Permissioned Media graciously offers instructions on how to remove the downloaded application from your hard drive. Antivirus company F-Secure suggests that if you think this marketing practice is unethical, you should complain directly to Permissioned Media. The FriendGreetings and F-Secure sites tell you how to contact the company.

Always read the fine print
So what's the lesson to be learned from this new threat? Be wary the next time you're asked to download a new plug-in for your browser--or any software from an unknown source. I suggest that you at least skim the EULA you're offered. If the company is asking for your permission in order to evade legal hassles, it must say what it intends to do to your PC.

And, as always, if you ever have a bad feeling while visiting a Web site or reading a user agreement for a download, you're probably better off avoiding the site and its software altogether.

What do you think of Permissioned Media's new tactic? Will malicious code writers exploit this feature in the future? Why or why not? TalkBack to me!
