Subsequent to a 2001 disclosure of a severe design flaw in the algorithm, WEP was never again secure in practice. In the vast majority of cases, Wi-Fi hardware devices relying on WEP security could not be upgraded to secure operation.
Jul 14, 2023 · The key encrypts the data transferred between the devices connected to the router, preventing unauthorized access. However, as time passed, security researchers discovered serious flaws in the WEP protocol. These flaws made it easy for attackers to crack the encryption and gain access to the network.
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.
Dec 6, 2022 · In 2017, Belgian security researcher Mathy Vanhoef discovered a major security flaw in WPA2, known as the key reinstallation attack (KRACK) vulnerability, which exploits the reinstallation of wireless encryption keys.

Mar 10, 2019 · While it was nice that people were actually using WEP, this early security protocol was still pretty terrible—for one thing, it used deliberately-weak RC4 encryption, because the US Government ...
However, as wireless networks began to grow in popularity, many crypt analysts and researchers discovered flaws in the original WEP design. Many believe that there was little peer review performed on the WEP protocol.
Jul 6, 2015 · For 128-bit WEP, it is 104 bit WEP key (13 ascii characters) and 24 bits from the IV. One of the huge flaws of WEP is that the IVs aren't unique and will end repeating over time in a busy network, due to its limited size. Don't use WEP, use WPA instead.
