About how long would it take to get the password for a network with AirSnort?
To crack a WEP password, AirSnort needs a certain number of packets with weak keys. Out of the sixteen million keys which can be generated by WEP cards, about nine thousand are weak (for 128 bit encryption.) Call these packets with weak keys “interesting.” Most passwords can be guessed with after about two thousand interesting packets. Some as few as 1200-1500, others as many as 3500-4000. To get an idea, assume that your business (it’s not very big yet) has four employees, all using the same password. These employees surf the net pretty continuously throughout the day (they’re not very good employees.) These employees will generate about a million packets a day. These employees will generate approximately a hundred and twenty interesting packets every day, so after sixteen days, the network will almost certainly be cracked. However, this network is nowhere near being saturated. As networks approach saturation, the capture time approaches a single day. In some situations, different phy
