When I use
aircrack-ng dump-file, I get a non-existent ESSID and can capture over 130,000 IVs, for example:
# BSSID ESSID Encryption 3 00:25:7B:4C:32:17 sanws WEP (137042 IVs)
Then if I try to crack this ESSID, it shows as cracked:
Attack will be restarted every 5000 captured ivs. Starting PTW attack with 137042 ivs. KEY FOUND! [ 73:61:6E:77:73 ] (ASCII: sanws ) Decrypted correctly: 100%
So the key is the same as the ESSID. And most important, the ESSID does not exist.
Why does this non-existent ESSID appear? What is it?
