Asterisk Hacking

Asterisk Hacking provides detials of techniques people may not be aware of. It teaches the secrets the bad guys already know about stealing personal information through the most common, seemingly innocuous, highway into computer networks: the phone system. This book provides detials to readers what they can do to protect themselves, their families, their clients, and their network from this invisible threat. Power tips show how to make the most out of the phone system for defense or attack. Contains original code to perform previously unthought of tasks like changing caller id, narrowing a phone number down to a specific geographic location, and more! See through the eyes of the attacker and learn WHY they are motivated, something not touched upon in most other titles.

Provides instructions for a variety of multimedia projects that can be done with Linux, including creating DVDs and VCDs, streaming audio and video over the Internet, and building a MythTV digital media hub.

Voice over Internet Protocol (VoIP) networks, the technology used to place phone calls through the Internet, suffer from the same security holes as standard IP networks. This book reviews the many possible VoIP attacks, and discusses the best defenses against them.

Voice over Internet Protocol is gaining a lot of attention these days. Both practical and fun, this text provides technology enthusiasts and voice professionals with dozens of hands-on projects for building a VoIP network, including a softPBX.

Johnny Long's last book sold 12,000 units worldwide. Kevin Mitnick's last book sold 40,000 units in North America. As the cliché goes, information is power. In this age of technology, an increasing majority of the world's information is stored electronically. It makes sense then that we rely on high-tech electronic protection systems to guard that information. As professional hackers, Johnny Long and Kevin Mitnick get paid to uncover weaknesses in those systems and exploit them. Whether breaking into buildings or slipping past industrial-grade firewalls, their goal has always been the same: extract the information using any means necessary. After hundreds of jobs, they have discovered the secrets to bypassing every conceivable high-tech security system. This book reveals those secrets; as the title suggests, it has nothing to do with high technology. • Dumpster Diving Be a good sport and don’t read the two “D” words written in big bold letters above, and act surprised when I tell you hackers can accomplish this without relying on a single bit of technology (punny). • Tailgating Hackers and ninja both like wearing black, and they do share the ability to slip inside a building and blend with the shadows. • Shoulder Surfing If you like having a screen on your laptop so you can see what you’re working on, don’t read this chapter. • Physical Security Locks are serious business and lock technicians are true engineers, most backed with years of hands-on experience. But what happens when you take the age-old respected profession of the locksmith and sprinkle it with hacker ingenuity? • Social Engineering with Jack Wiles Jack has trained hundreds of federal agents, corporate attorneys, CEOs and internal auditors on computer crime and security-related topics. His unforgettable presentations are filled with three decades of personal "war stories" from the trenches of Information Security and Physical Security. • Google Hacking A hacker doesn’t even need his own computer to do the necessary research. If he can make it to a public library, Kinko's or Internet cafe, he can use Google to process all that data into something useful. • P2P Hacking Let’s assume a guy has no budget, no commercial hacking software, no support from organized crime and no fancy gear. With all those restrictions, is this guy still a threat to you? Have a look at this chapter and judge for yourself. • People Watching Skilled people watchers can learn a whole lot in just a few quick glances. In this chapter we’ll take a look at a few examples of the types of things that draws a no-tech hacker’s eye. • Kiosks What happens when a kiosk is more than a kiosk? What happens when the kiosk holds airline passenger information? What if the kiosk holds confidential patient information? What if the kiosk holds cash? • Vehicle Surveillance Most people don’t realize that some of the most thrilling vehicular espionage happens when the cars aren't moving at all!
