Wired Equivalent Privacy or WEP is a wireless encryption code developed in 1999 that retailers began to implement. Within a couple of years hackers broke the encryption code and rendered WEP obsolete. Many retailers never changed to updated encryption codes such as WPA or WPA2. TJX never upgraded and once hackers got access‚ they were able to sniff out transmissions

its architecture. In order to examine the WLAN security threats‚ this paper will look at Denial of Service‚ Spoofing‚ and Eavesdropping. The paper will then explain how Wired Equivalent Privacy (WEP) works‚ which is the IEEE 802.11b/WiFi standard encryption for wireless networking. The discussion of WEP continues by examining its weaknesses‚ which result in it being much less secured than what was originally intended. This situation leads to further research regarding practical solutions in implementing

Breaking 104 bit WEP in less than 60 seconds Erik Tews‚ Ralf-Philipp Weinmann‚ and Andrei Pyshkin <e tews‚weinmann‚pyshkin@cdc.informatik.tu-darmstadt.de> TU Darmstadt‚ FB Informatik Hochschulstrasse 10‚ 64289 Darmstadt‚ Germany Abstract. We demonstrate an active attack on the WEP protocol that is able to recover a 104-bit WEP key using less than 40‚000 frames with a success probability of 50%. In order to succeed in 95% of all cases‚ 85‚000 packets are needed. The IV of these packets can be randomly

Open system authentication (SSID beaconing) Disables SSID from being broadcast so wireless networks are harder to detect. A spectrum analyzer can still be used to find the network name. Create a more complex SSID and password settings in your AP WEP Stands for Wired Equivalency Privacy. Uses 64 bit or 128 bit encryption. (including 24-bit IV) In larger networks‚ IV’s can be duplicated and cause collisions‚ which are easy to detect by outside influences Use WPA2 with AES or similar instead on
