What he means is that while the password you initially enter on Web sites like Facebook, Twitter, Flickr, Amazon, e. Bay and The New York Times is encrypted, the Web browsers cookie, a bit of code that that identifies your computer, your settings on the site or other private information, is often not encrypted. How To Use Gerix Wifi Cracker' title='How To Use Gerix Wifi Cracker' />Firesheep grabs that cookie, allowing nosy or malicious users to, in essence, be you on the site and have full access to your account. More than a million people have downloaded the program in the last three months including this reporter, who is not exactly a computer genius. And it is easy to use. Hirens Boot DVD es una compilacin de utilidades que a cualquier profesional o aficionado a la administracin de sistemas le ser de gran provecho. Dicha. BackTrack was a Linux distribution that focused on security, based on the Knoppix Linux distribution aimed at digital forensics and penetration testing use. In March. The only sites that are safe from snoopers are those that employ the cryptographic protocol Transport Layer Security or its predecessor, Secure Sockets Layer, throughout your session. Pay. Pal and many banks do this, but a startling number of sites that people trust to safeguard their privacy do not. You know you are shielded from prying eyes if a little lock appears in the corner of your browser or the Web address starts with https rather than http. The usual reason Web sites give for not encrypting all communication is that it will slow down the site and would be a huge engineering expense, said Chris Palmer, technology director at the Electronic Frontier Foundation, an electronic rights advocacy group based in San Francisco. Yes, there are operational hurdles, but they are solvable. Indeed, Gmail made end to end encryption its default mode in January 2. Facebook began to offer the same protection as an opt in security feature last month, though it is so far available only to a small percentage of users and has limitations. For example, it doesnt work with many third party applications. Its worth noting that Facebook took this step, but its too early to congratulate them, said Mr. Butler, who is frustrated that https is not the sites default setting. Most people arent going to know about it or wont think its important or wont want to use it when they find out that it disables major applications. Joe Sullivan, chief security officer at Facebook, said the company was engaged in a deliberative rollout process, to access and address any unforeseen difficulties. We hope to have it available for all users in the next several weeks, he said, adding that the company was also working to address problems with third party applications and to make https the default setting. Many Web sites offer some support for encryption via https, but they make it difficult to use. To address these problems, the Electronic Frontier Foundation in collaboration with the Tor Project, another group concerned with Internet privacy, released in June an add on to the browser Firefox, called Https Everywhere.

Since not all Web sites have https capability, Bill Pennington, chief strategy officer with the Web site risk management firm White. Hat Security in Santa Clara, Calif., said I tell people that if youre doing things with sensitive data, dont do it at a Wi Fi hot spot. Do it at home. But home wireless networks may not be all that safe either, because of free and widely available Wi Fi cracking programs like Gerix Wi. Fi Cracker, Aircrack ng and Wifite. The programs work by faking legitimate user activity to collect a series of so called weak keys or clues to the password. The process is wholly automated, said Mr. Kitchen at Hak. 5, allowing even techno ignoramuses to recover a wireless routers password in a matter of seconds. Ive yet to find a WEP protected network not susceptible to this kind of attack, Mr. Decrypt P File Matlab Code. Kitchen said. A WEP encrypted password for wired equivalent privacy is not as strong as a WPA or Wi Fi protected access password, so its best to use a WPA password instead. Even so, hackers can use the same free software programs to get on WPA password protected networks as well. It just takes much longer think weeks and more computer expertise. Using such programs along with high powered Wi Fi antennas that cost less than 9. There are also some computerized cracking devices with built in antennas on the market, like Wifi. Robin 1. 56. But experts said they were not as fast or effective as the latest free cracking programs, because the devices worked only on WEP protected networks. To protect yourself, changing the Service Set Identifier or SSID of your wireless network from the default name of your router like Linksys or Netgear to something less predictable helps, as does choosing a lengthy and complicated alphanumeric password. Setting up a virtual private network, or V. P. N., which encrypts all communications you transmit wirelessly whether on your home network or at a hot spot, is even more secure. The data looks like gibberish to a snooper as it travels from your computer to a secure server before it is blasted onto the Internet. Popular V. P. N. providers include Vypr. VPN, Hot. Spot. VPN and Log. Me. In Hamachi. Some are free others are as much as 1. Free versions tend to encrypt only Web activity and not e mail exchanges. However, Mr. Palmer at the Electronic Frontier Foundation blames poorly designed Web sites, not vulnerable Wi Fi connections, for security lapses. Many popular sites were not designed for security from the beginning, and now we are suffering the consequences, he said. People need to demand https so Web sites will do the painful integration work that needs to be done. Correction February 2. An article in the Personal Tech pages on Feb. Wi Fi users vulnerability to hackers misspelled the name of a provider of virtual private networks, which can be used to thwart hackers. It is Vypr. VPN, not Vyper. VPN.
