Facebook 'ideal' for phishing attacks: researcher

Security researcher Nick Sullivan over at Symantec Corporation believes that privacy settings on social networking websites such as Facebook give people a false sense of security that could expose them to phishing attacks. "This illusion of privacy leads people to be a little freer in their disclosure," he wrote in a post to the company's security response weblog. Private information, ranging from e-mail and phone number to physical address, can all be available to the determined phisher or identity thief. One way to do get to the information is to seize control of the account of someone designated a friend or someone in the same network, he said.

Phishers can easily engineer fake notifications that follow the format of legitimate friend requests e-mailed to Facebook members, for example. A typical e-mail would ask a user to click on a link to confirm that they are friends with an individual requesting addition as a friend on the network. Some users almost reflexively log in to a site through a link provided in an e-mail, he noted. "This simple, clean design is very easy for a phisher to mimic. … This makes Facebook users ideal targets for the type of generic phishing attacks that are usually directed at financial institutions."

I disable Facebook's ability to e-mail me anything. I simply log into the site the regular way whenever I want to visit. After all, I don't need to log in every time someone requests me as a friend, or writes on my wall. If others followed the same example..it would just be a matter of setting appropriate privacy settings.

Or you could just look at the url in the address bar after you click a link and make sure it actually says <network>.facebook.com/<etcetc> and not something else... This behavior is otherwise known as not being an idiot on the internet.

Heh. I think the idea is that most people don't do that, that's why phishing e-mails work! So unfortunately, rather than fix user behaviour (ideal), we're stuck with patching user behaviour instead (don't have Facebook send e-mail). Cheers!

This doesnt really affect me as if i receive an email from facebook than i delete it and open facebook.com I have never clicked on the link in an email, not sure why.

I do the same, it's one way to ensure you are not being "phished"

I have my profile on the highest restrictions, i'm not stupid....

I don't accept friend requests from people I don't know. Same goes to clicking on links from people I don't know.

The solution to this is being annoying so you dont have any friends, then no-one will add you, and therefore you will know its not a real facebook email when you recieve one

That's spooky. Only a couple of hours ago I received an email saying that someone or other had added me as a friend or something. But it was sent to one of my accounts that is nothing to do with facebook. I'm going to do what comment 1 said; sounds like a good idea to me.

Pfft... If neowin implements tagging like slashdot, this would surely be tagged "duh".

Any social networking site, or just any website frequented by people that come from non-technical background (in case you haven't noticed, they outnumber us geeks who know which site to click and which not to) is "Ideal" for phishing attacks.

I honestly envy the job of these so-called "researchers"

Did anyone else stop reading after "security researcher" and "Symantec Corporation"?

Check this out, Symantec: Since Facebook doesn't rely on encrypted data transmission, there is no "illusion of privacy". No data exchanged on a website that's not secure (http://) is private.

Symantec actually pays this guy?

I could see how loads of people would fall victim to this if it started happening.

Do people REALLY post their phone numbers, home/work addresses, and other contact information? If they do, they should be shot.... or bared from the internet.
#13 black_death on 16 Apr 2007 - 20:40
what a moron, any site with lots of users is "ideal" for phishing attacks!
