![]() It isn’t all bad news: you can simply disable the WPS feature on your router to remove the PIN that the likes of Reaver will be looking for. Reduce that time and resource requirement sufficiently and suddenly your router and Wi-Fi network become more attractive targets for a casual hack. Remember, it matters not a jot how complex the PSK lying behind your PIN is – by using the WPS PIN method, you’ve “protected” your Wi-Fi network using what is in effect only four digits.Ī Google search for PSK hacking tutorials will demonstrate that even without this WPS PIN vulnerability it’s quite feasible to find a WPA2-PSK by brute force, but it would take very much longer and a potential hacker would need a very good reason to invest the time and resources required. Wps pin calculator full#The full PIN would have more than ten million combinations, but the reduced digit PIN has only 11,000 or thereabouts. Security researchers have released a tool called Reaver that can exploit this flaw, and enables anyone to crack the simpler WPS PIN and access the cleartext version of the router’s WPA2 pre-shared key (PSK), which is then revealed as a result. (There’s a useful “how long to crack my password” calculator at the Steve Gibson GRC security site: maths boffins will point out its shortcomings, but it’s good enough for back-of-a-fag-packet estimates.) To gain access to your supposedly secure wireless network, on the other hand, he doesn’t require physical access to your router, computer or anything else – he can just set his own PC to try every possible combination. To take your money out of an ATM, any would-be bad guy has to be in possession of your physical card as well as being able to guess or otherwise obtain its PIN. Sure, bank cards employ a four-digit PIN and both the banks and their customers seem happy enough to place their trust in this when using cards in a cash machine, but there’s a big difference between these two seemingly identical instances of authentication. Yes, you read that correctly: that secure-looking PIN isn’t all that secure. ![]() Wps pin calculator manual#WPS is that button you probably pressed to secure your wireless router when you were setting it up for your home or small-business network, the one that helpfully did away with all the manual security configuration and made setting up wireless security both simple and quick. Such trust is often misplaced, which is where the potential security risk lies, and which lines me up nicely for the actual story that caught my attention – namely, that the Wi-Fi Protected Setup (WPS) protocol has been well and truly compromised.

These same folk are far more likely to secure their home Wi-Fi, so it isn’t just a failure of awareness but more like an excess of trust. Of those asked, 56% never or rarely check to see whether a hotspot is encrypted before logging into it. ![]()
