Building a Blind IP Spoofed Portscanning Tool

Explore the intricacies of building a blind IP spoofed portscanning tool in this 44-minute Black Hat USA 2001 conference talk by Thomas Olofsson. Delve into the fundamentals of TCP/IP handshakes and definitions before examining traditional port scanning techniques with practical examples and analysis. Learn about noise reduction, timing calculations, and the tool's adaptation to Windows 2000 raw sockets. Discover the functionalities of the spoofer, including host scanning, verbosity options, and result interpretation. Investigate packet behavior, open port detection, and ID counter mechanisms. Address challenges posed by stateful firewalls and explore the tool's accuracy when scanning multiple hosts. Gain insights into the development process, potential applications, and ethical considerations surrounding this advanced network security tool.
