Router manufacturers have strong algorithms to generate key WPA2

Router manufacturers have strong algorithms to generate key WPA2










From the first routers with WEP key that came with a key by default, manufacturers have designed algorithms for unsafe key generation Wi-Fi, a good example of this was the famous WLAN_XX dictionaries and Jazztel_XX all remember. With WPA and WPA2 keys it has been different, so that customer safety is at stake.

In 2010 the Internet operator with more customers from Spain, Movistar launched a series of routers Comtrend an internal algorithm for key generation WPA and WPA2 data based on different internal and wireless MAC (BSSID) and the MAC LAN among other parameters.

Since then, security researchers have focused on getting that key generation algorithm using different methods such as through the firmware out itself. If the firmware is not available, such as routers most operators because they are updated via TR-069, have been extracted information through JTAG and UART interfaces in addition also able to physically access memory FLASH team to find the information inside.

Router manufacturers when such failures they do is slightly modify the algorithm discovered "patch" around the problem, because they have also finally got out was discovered.

Comtrend is not the only one affected manufacturer, the manufacturer Sitecom selling neutral routers and ADSL2 + in stores (not like Comtrend only sold to operators) is also affected by these security flaws that allow find the default wireless password quickly. Some of the affected models are:

    Sitecom WLM-3500
    Sitecom WLM-5500
    Sitecom WLR-4000
    Sitecom WLR-4004

Besides finding algorithm, Italian researchers have also found several backdoors and security flaws in the user interface of the router management.

Spanish security researcher Eduardo Novella , has also found other security flaws in other models, for example the Sitecom WLR-2100 Sitecom WLR-2500 and has discovered new key generation algorithms and confirmed that all models Sitecom WLR -XXX use the same also in the WL-XX routers has also discovered the new algorithm. In 90% of these routers only you need the BSSID to get the WPA key and WPA2 default.

Other manufacturers that Eduardo has investigated are Thomson, Arcadyan and ADB / Pirelli with the same result. Eduardo Novella has presented all his research on the algorithms for key generation WPA2 wireless routers in the Black Hat 2015 held in Las Vegas, his presentation was entitled.
