wireless securitynetwork assessmentconfigurationsInvestigating Rogue Access Points and Config Flaws in Retail Wi-Fi Security
For almost 18 months starting in 2005, attackers used wireless networks at TJX and other retail chains to steal credit card data. The vulnerabilities were not an isolated instance: Subsequent research found that about half of all retail outlets in one shopping center had insecure wireless networks.. Today, WiFi security has improved somewhat, but insecurities in installations still remain far too common. Vulnerability assessments of more than two dozen companies found a quarter have rogue wireless access points that were installed by employees, and a third of their wireless networks had misconfigurations that undermined their security, according to wireless security firm AirTight Networks, which conducted the tests. "A rogue AP is a very serious problem if you have it -- an unmanaged, unknown device that is circumventing your defenses," says David King, CEO of AirTight. "All the layers of defense that you worked so hard to put in can be circumvented by a single device that is communicating in the clear."

social engineeringsecurity trainingnetwork assessmentExamining USB Social Engineering Tactics in Network Security Assessment
We recently got hired by a credit union to assess the security of its network. The client asked that we really push hard on the social engineering button. In the past, they'd had problems with employees sharing passwords and giving up information easily. Leveraging our effort in the report was a way to drive the message home to the employees. The client also indicated that USB drives were a concern, since they were an easy way for employees to steal information, as well as bring in potential vulnerabilities such as viruses and Trojans. Several other clients have raised the same concern, yet few have done much to protect themselves from a rogue USB drive plugging into their network. I wanted to see if we could tempt someone into plugging one into their employer's network. . In the past we had used a variety of social engineering tactics to compromise a network. Typically we would hang out with the smokers, sweet-talk a receptionist, or commandeer a meeting room and jack into the network. This time I knew we had to do something different. We heard that employees were talking within the credit union and were telling each other that somebody was going to test the security of the network, including the people element. We figured we would try something different by baiting the same employees that were on high alert. We gathered all the worthless vendor giveaway thumb drives collected over the years and imprinted them with our own special piece of software. I had one of my guys write a Trojan that, when run, would collect passwords, logins and machine-specific information from the user’s computer, and then email the findings back to us.
