For modern, complex environments, Nmap is vastly more powerful. However, for a quick, no-fuss scan on a Windows legacy network, Woron Scan 1.09 is still a gem.
The proliferation of Global System for Mobile Communications (GSM) technology in the late 1990s and early 2000s established the first standardized digital cellular network. Central to the security of this architecture was the Subscriber Identity Module (SIM), a smart card designed to authenticate the subscriber to the network. The security of this system relied heavily on the A3/A8 authentication and session key generation algorithms, most commonly implemented via the COMP128 reference algorithm. Woron Scan 1.09
Woron Scan implemented a method based on research by security researchers (such as the ISAAC group at Berkeley) that identified a flaw in the compression function of COMP128. Specifically, the algorithm suffered from the "narrow pipe" problem, where internal state collisions could be induced. For modern, complex environments, Nmap is vastly more
