Overview Hacking is the art of creative problem solving, whether that m eans finding an unconventional solution to a difficult problem or exploiting holes in sloppy program m ing. Many people call them selves hackers, but few have the strong technical foundation needed to really push the envelope. Rather than m erely showing how to run existing exploits, author Jon Erickson explains how arcane hacking techniques actually work. To share the art and science of hacking in a way that is accessible to everyone, Hacking: The Art of Exploitation, 2nd Edition introduces the fundam entals of C program m ing from a hacker's perspective. The included LiveCD provides a com plete Linux program m ing and debugging environm ent-all without m odifying your current operating system . Use it to follow along with the book's exam ples as you fill gaps in your knowledge and explore hacking techniques on your own. Get your hands dirty debugging code, overflowing buffers, hijacking network com m unications, bypassing protections, exploiting cryptographic weaknesses, and perhaps even inventing new exploits. This book will teach you how to: Program com puters using C, assem bly language, and shell scripts Corrupt system m em ory to run arbitrary code using buffer overflows and form at strings I nspect processor registers and system m em ory with a debugger to gain a real understanding of what is happening Outsm art com m on security m easures like nonexecutable stacks and intrusion detection system s Gain access to a rem ote server using port-binding or connect-back shellcode, and alter a server's logging behavior to hide your presenc
