But if the attacker can send each request with a different MAC address they can bypass the lock down. It can provide a much longer average time to find the PIN (a 60-minute lock down after 5 failed attempts leads to a 114-year average time to find the PIN) while still allowing legitimate clients with a different MAC address to authenticate. If it’s difficult for the attacker to spoof their MAC address, then a per-MAC-address complete lock down is even better. A 30-second delay strikes me as a good compromise between resistance to brute force attacks and responding to legitimate requests. This has the advantage that a legitimate client with the correct PIN can still authenticate, even if the device is under a brute force attack. A 30-second delay per failed attempt requires 1,811 days (4.9 years) on average to find the PIN, 60 seconds requires 3,547 days (9.7 years). Rather than a complete lock down after a few failed attempts, I think it would be better to introduce a delay after receiving a few (5 or 10) failed attempts. That brings the required number of brute force attempts back up to 10^7, which means it will take over 150 days to search the entire space with your assumed attack time of 1.3 seconds per attack, even without any lock down (or 75 days, on average, to find the PIN). Always send the second half of the negotiation, and send EAP-NACK in response to the second half of the PIN if either half was incorrect. The other mitigation that should be recommended is to never send EAP-NACK in response to the first half of the PIN. It’s a bit faster than Reaver, but will not work with all Wi-Fi adapters.

Craig and his team have now released their tool “Reaver” over at Google Code. I would like to thank the guys at CERT for coordinating this vulnerability.Īs you probably already know, this vulnerability was independently discovered by Craig Heffner ( /dev/ttyS0, Tactical Network Solutions) as well – I was just the one who reported the vulnerability and released information about it first. To my knowledge none of the vendors have reacted and released firmware with mitigations in place.ĭetailed information about this vulnerability can be found in this paper: Brute forcing Wi-Fi Protected Setup – Please keep in mind that the devices mentioned there are just a tiny subset of the affected devices. CERT/CC has assigned VU#723755 to this issue. I reported this vulnerability to CERT/CC and provided them with a list of (confirmed) affected vendors. As all of the more recent router models come with WPS enabled by default, this affects millions of devices worldwide. I noticed a few really bad design decisions which enable an efficient brute force attack, thus effectively breaking the security of pretty much all WPS-enabled Wi-Fi routers. It can be integrated into existing networks via LAN or wireless LAN, serving as a high-speed access point or wireless hotspot.A few weeks ago I decided to take a look at the Wi-Fi Protected Setup (WPS) technology. When used as a wireless repeater, the FRITZ!Box makes extending your wireless range child’s play.

You have a usage log, while your guests benefit from an integrated QR code that makes it easy for them to connect to the Internet. When using your FRITZ!Box as a hotspot, you can restrict Internet usage to surfing and e-mail. Simply press the 'WPS' or 'WLAN' button on the FRITZ!Box and on the new device – and it will be securely and automatically registered with the network.
Thanks to WPS (Wi-Fi Protected Setup), you can connect new wireless-enabled devices in a flash. The intelligent auto channel search can be used to select the best wireless channel. The FRITZ!Box simultaneously uses both the 2.4 and 5 GHz frequency bands, offering maximum flexibility for all devices. With FRITZ!Box, you're ready for the future: as vectoring is supported, you can reach throughput rates of up to 100 Mbit/s with standard VDSL connections and double your Internet speed without any extra hardware.

Testet with reaver -p 'PIN' -got WPA Key.
