February 09, 2011, 5:48 PM — Chris Hadnagy gets paid to fool people, and he's gotten pretty good at it over the years. A co-founder of social-engineering.org and author of Social Engineering: The Art of Human Hacking, Hadnagy has been using manipulation tactics for more than a decade to show clients how criminals get inside information.
Hadnagy outlines three memorable stories of social engineering tests that he's included in his new book (you can also read a short excerpt), and points out what organizations can learn from these results.
The Overconfident CEO
In one case study, Hadnagy outlines how he was hired as an SE auditor to gain access to the servers of a printing company which had some proprietary processes and vendors that competitors were after. In a phone meeting with Hadnagy's business partner, the CEO informed him that "hacking him would be next to impossible" because he "guarded his secrets with his life."
"He was the guy who was never going to fall for this," said Hadnagy. "He was thinking someone would probably call and ask for his password and he was ready for an approach like that."

After some information gathering, Hadnagy found the locations of servers, IP addresses, email addresses, phone numbers, physical addresses, mail servers, employee names and titles, and much more. But the real prize of knowledge came when Hadnagy managed to learn the CEO had a family member that had battled cancer, and lived. As a result, he was interested and involved in cancer fundraising and research. Through Facebook, he was also able to get other personal details about the CEO, such as his favorite restaurant and sports team.
Armed with the information, he was ready to strike. He called the CEO and posed as a fundraiser from a cancer charity the CEO had dealt with in the past. He informed him they were offering a prize drawing in exchange for donations--and the prizes included tickets to a game played by his favorite sports team, as well as gift certificates to several restaurants, including his favorite spot.
The CEO bit, and agreed to let Hadnagy send him a PDF with more information on the fund drive. He even managed to get the CEO to tell him which version of Adobe reader he was running because, he told the CEO "I want to make sure I'm sending you a PDF you can read." Soon after he sent the PDF, the CEO opened it, installing a shell that allowed Hadnagy to access his machine.
