What was a key vulnerability of WEP security in WiFi?

WEP (Wired Equivalent Privacy) had significant vulnerabilities, one of the most critical being its lack of proper rotation of shared secrets. In WEP, the same key was often used for long periods, making it easier for attackers to intercept and analyze the traffic transmitted over a wireless network. Without regular updates or rotation of the encryption key, once an attacker could capture enough packets, they could perform statistical analysis and potentially crack the key using tools available in the hacking community.

This static use of keys allowed for repeated patterns in wireless communication, which contributed to the overall weakness of WEP security. As understanding and technology around hacking advanced, the vulnerabilities of WEP became more prominent, leading to its eventual deprecation in favor of more secure protocols such as WPA (Wi-Fi Protected Access) and WPA2, which employ more robust key management and encryption methods.

In contrast, the other statements reflect aspects that do not accurately describe WEP's vulnerabilities, such as the notion of rotating shared secrets or implying that WEP was impossible to crack, both of which misrepresent the nature of this outdated security standard.
