Social Engineering Fundamentals, Part I: Hacker Tactics
Source: SecurityFocus
L33tdawg: This is a damn good article and a topic that has always been an interesting aspect of the hacking situation to me. It seems so much more 'elegant' to social engineer your way into a network in ADDITION to breaking in the more 'traditional' way. Then again, perhaps I've been watching too many spy movies! *grin*
One morning a few years back, a group of strangers walked into a large shipping firm and walked out with access to the firm’s entire corporate network. How did they do it? By obtaining small amounts of access, bit by bit, from a number of different employees in that firm. First, they did research about the company for two days before even attempting to set foot on the premises. For example, they learned key employees’ names by calling HR. Next, they pretended to lose their key to the front door, and a man let them in. Then they "lost" their identity badges when entering the third floor secured area, smiled, and a friendly employee opened the door for them.
The strangers knew the CFO was out of town, so they were able to enter his office and obtain financial data off his unlocked computer. They dug through the corporate trash, finding all kinds of useful documents. They asked a janitor for a garbage pail in which to place their contents and carried all of this data out of the building in their hands. The strangers had studied the CFO's voice, so they were able to phone, pretending to be the CFO, in a rush, desperately in need of his network password. From there, they used regular technical hacking tools to gain super-user access into the system.
In this case, the strangers were network consultants performing a security audit for the CFO without any other employees' knowledge. They were never given any privileged information from the CFO but were able to obtain all the access they wanted through social engineering. (This story was recounted by Kapil Raina, currently a security expert at Verisign and co-author of mCommerce Security: A Beginner's Guide, based on an actual workplace experience with a previous employer.)
