Hello,

I have turned off SSID broadcast and its pretty obscure, the password is
obscure too, its WPA personal, i think its impossible to crack/get in my
router without knowing SSID :D .

Regards,

 Sure. But one question remains: is it worth it ? Using a botnet to crack
 John Doe's PSK where you can just push password stealing malware on his
 box ?

 My problem with this kind of announce is that it seems to make people
 believe that cracking WPA/WPA2 is easy, just like WEP. But it is not,
 and really far from it. Maybe, or likely, some day, not that far away,
 someone will come up with a crypto or implementation flaw that will
 crush them down, but right now, it is not the case.

 So we stuck to a password guessing game. A game we play for years, with
 password hashing algorithms that we are *way* more efficient at cracking
 than a PBKDF2.

 I don't say we can't break PSK. I say that we suck at it with current
 implementations, even with a x100 performance increase.

But your SSID is very easy to retrieve, as it is leaked every time you
associate a legitimate box to your wlan... And guess what: the regular
process of cracking a WPA PSK implies disassociating a client to sniff
the 4-way handshake. Doing this, the attacker will also sniff SSID
cleartext in the air.

Which means: *do not* rely on SSID cloaking for your security.
