Social Engineering and Firewall Subversion
SANS denotes Social engineering as one of the top 4 methods for getting into the internal network and behind the firewall. I would have to agree and rank at least in the top 2 of the 4. Think of it in logical terms. Linkedin tracks your professional background. I look you up on Linkedin and already know your place of business. This is helpful with probing the helpdesk for internal credentials.

If I can foster an email correspondence with anyone at the enterprise, as long as the email isn't aliased, I could possibly have your username. From there facebook could be used to pull personal data and maybe hone down the field of a password possibility if you create your own passwords. With this put into the specialized fields of a dictionary attack, it could take a lot less time to discover your password.

Now account lockouts are the next piece of security that would prevent intrusion. But if I am a hacker I do not want to go on site and try to bypass physical security as well. I would rather try and find an in remotely. Next step for me is to call the helpdesk for remote documentation. Some enterprises have multiple avenues for working remotely. Going back to my previous point about lockouts, the functionality of a remote client is to allow you to work from anywhere. Functionality is the main purpose here. Many don't have a lockout mechanism. So I can try to log in remotely as many times as I want, making my dictionary attack much more efficient. Once I have the credentials. I log in remotely during off hours, and because I don't need to change your password you may not be any the wiser. 

This is all thanks to social engineering.

Re: Traditional defenses
It is very easy to fall for something like that on a social network, especially after the scammer gets one person who you trust to friend them. Then it can cascade, because other people will say, 'well if so and so knows her from our company, I must have met her as well' or 'that person must be trustworthy.' It is a good way to conduct reconnaissance for spear-phishing.

Re: A Fascinating Look
Exactly! I have several people hanging in limbo right now for that very reason! Though I doubt any of them are losing sleep over it. :)

Re: A Fascinating Look
So true. I find myself thinking I have to appear rude rather than risk getting 0wned when I get requests for connections to folks I don't know or remember!

Re: A Fascinating Look
That's wild -- but it's easy to see how people could fall for it. I recall almost falling victim to something a few weeks ago when a real friend's Facebook was hijacked. A fraudulent account was created in his name and the fraudster sent friend requests out. Fortunately, my real friend notified all his contacts about the fake account set up in his name (with his photo) so I didn't accept the duplicate friend request. But I would have done, probably, thinking he or FB had done something to his original account by mistake. 

And we all meet so many people that it's hard to recall all their names. If someone seems legit and mentions meeting you at a conference three months ago, odds are many of us might take this at face value rather than run the risk of offending someone who appeared legit!

Re: Traditional defenses
No, I don't think those suggestions are good enough. Especially when you're dealing with a group like this, which uses real journalists' names to try and reach its targets.

Re: A Fascinating Look
This is reminiscent of the controversial "Robin Sage" experiment conducted a few years back, where a phony persona was set up on LinkedIn, Facebook and Twitter to see who would connect to "Robin," who scored connections with people in the Joint Chiefs of Staff, the CIO of the NSA, an intelligence director for the U.S. Marines, a chief of staff for the U.S. House of Representatives, and several Pentagon and DoD employees. "She" even got job offers and dinner invites. Robin Sage and this Iranian campaign demonstrate how easy it is to fall into the trap of trusting someone online without truly vetting them. Anyone can fall victim to this, which is what makes it so disturbing.

It's pretty scary to think how defenseless we are against social engineering. Are best-practices like "don't [connect] or friend people you don't know, and don't endorse them for skills on LinkedIn if you don't know" enough to stop a determinined attacker?

Re: A Fascinating Look
Social Media is  a powerful instrument for military operation. I wrote an excellent post on the topic more than one year ago where are explained all the techniques based on exploitation of social networking platform.

Let me also another post we it is explained how to "poison" a social network for various purposes.
