A few months back i found a wireless AP of a leading Indian cellular network near my apartment, my laptop could connect to it automatically. - access to the internet was wide open. - packets could be easily sniffed using Cain and ettercap. Plaintext passwords could be intercepted without much effort. - other vulnerable ports could be discovered using nmap scans.
So my idea is- to create a nmap plugin for openmoko phones,that would automatically scan the networks in range using nmap ,discover vulnerabilities and respond to the admin with the log files so that the vulnerabilities could be fixed.
