S'han tornat a posar de moda els microtalls durant aquest any 2007. De fet, tot just n'acabo de patir un...

Relacionat: Subministrament elèctric l'any 2004: menys microtalls i més hores a les fosques. Hauré de tornar a fer el recull de talls de subministrament elèctric, aprofitant que ja són ben bé tres anys de dades.

[News.com] Your Wi-Fi can tell people a lot about you. El sol fet d'arrencar la màquina amb la xarxa Wi-Fi activa, fa que es transmeti una certa quantitat d'informació sobre el nostre ordinador.
Soon after a computer powers up, it starts looking for wireless networks and network services. Even if the wireless hardware is then shut-off, a snoop may already have caught interesting data.
There are many tools that let anyone listen in on wireless network traffic. These tools can capture information such as usernames and passwords for e-mail accounts and instant message tools as well as data entered into unsecured Web sites. At the annual Defcon hacker gathering, a "wall of sheep" always lists captured log-in credentials.
Errata has developed another network sniffer that looks for traffic using 25 protocols, including those for the popular instant message clients as well as DHCP, SMNP, DNS and HTTP. This means the sniffer will capture requests for network addresses, network management tools, Web sites queries, Web traffic and more.
"You don't realize how much you're making public, so I wrote a tool that tells you," said Robert Graham, Errata's chief executive. The tool will soon be released publicly on the Black Hat Web site. Anyone with a wireless card will be able to run it, Graham said. Errata also plans to release the source code on its Web site.
The Errata sniffer, dubbed Ferret, packs more punch than other network sniffers already available, such as Ethereal and Kismet, because it looks at so many different protocols, Graham said. Some at Black Hat called it a "network sniffer on steroids."
De fet, Ferret ja està disponible.
FERRET - a broadcast analysis tool
This tool is designed to demonstrate the problem of "data seapage". The average machine broadcasts a lot of information about itself on open networks. This tool captures and organizes this information.
This code is extremely low quality, hacked together in order to demonstrate the problem at the BlackHat Federal 2007 conference. Higher quality code should be available around May 2007 on our website at http://www.erratasec.com.
To build this for Windows, you need the WinPcap developer kit. This code should compile on other platforms, such as Linux, Solaris, MacOS, and other platforms with libpcap.
