WebDec 19, 2024 · The RC4 key for that packet is the IV concatenated with the WEP key. WEP keys have to be changed manually and this typically happens infrequently. An attacker therefore can assume that all the keys used to encrypt packets share a single WEP key. This fact opened up WEP to a series of attacks which proved devastating. WebNov 8, 2024 · WPA was doomed from the outset. Despite featuring stronger public key encryption (than WEP), using 256-bit WPA-PSK (Pre-Shared Key), WPA still contained a string of vulnerabilities it inherited from the older WEP standard (both of which share the vulnerable stream encryption standard, RC4).
