As we research computer problems, we find interesting articles about security, useful applications, website design and solving computer problems. We hope you find these tidbits useful.

(January 2001) Researchers at the University of California at Berkely independently released a paper describing the problems with WEP. Their web page can be found here ( http://www.isaac.cs.berkeley.edu/isaac/wep-faq.html ). Executive Summary We have discovered a number of flaws in the WEP algorithm, which seriously undermine the security claims of the system. In particular, we found the following types of attacks: * Passive attacks to decrypt traffic based on statistical analysis. * Active attack to inject new traffic from unauthorized mobile stations, based on known plaintext. * Active attacks to decrypt traffic, based on tricking the access point. * Dictionary-building attack that, after analysis of about a day's worth of traffic, allows real-time automated decryption of all traffic. Our analysis suggests that all of these attacks are practical to mount using only inexpensive off-the-shelf equipment. We recommend that anyone using an 802.11 wireless network not rely on WEP for security, and employ other security measures to protect their wireless network. Note that our attacks apply to both 40-bit and the so-called 128-bit versions of WEP equally well. They also apply to networks that use 802.11b standard (802.11b is an extension to 802.11 to support higher data rates; it leaves the WEP algorithm unchanged).

At http://www.winaddons.com/top-300-freeware-software/ You will find 300 programs that can be downloaded and used for free. The author of the page categorized into 22 different groups. There are utilities, games, wallpapers, file sharing, and more. There are also pages of comments that are worth reading there. I'm going to try FreeMind - free mind mapping software and Kerio Personal Firewall 4.2.2 from sunbelt. I already use irfanview and ccleaner.

» Hacking IBM Thinkpad Bios Password: "Lost your IBM ThinkPad Supervisor password? No problem, on this page i will show you how to recover your old password. Although IBM claims their TP BIOS passwords are impossible to break, there is a easy and cheap way to fix this. The stuff you need cost about 5 $ at your closest radio shack type of store. Also you need a spare PC with a serial port. This article is based on a IBM ThinkPad T42. There are no guarantees and you might end up destroying your TP. So continue at your own risk.
