The Pairwise-Master-Key (PMK) is the foundation key of encrypted communication on nearly all WPA WiFi networks, including WPA2-Enterprise networks.
Typically, the PMK rekey interval for personal networks is around 2-3 hours.
But how often … Continue reading How often should a WPA2-Enterprise PMK be rekeyed in a high security, large corporate network? [closed]
1) Is this handshake (used to perform mutual authentication and to derive PTK and GTK) performed in WPA(TKIP)?
I think not, but I don’t understand why in a aircrack page it’s written that
There is no difference between cracking WPA or WP… Continue reading Does TKIP(WPA) implement the 4-way handshake? Or only RSN(WPA2) does implement it?
Brute force attack against WPA is the most common attack against WPA/WPA2 networks. Attacker captures the 4-way handshake that allows the authentication key to be cracked offline.
During the 4-way handshake, several pieces of information … Continue reading In WPA handshake brute force attack, how can attacker find PMK if MIC is performed using only HALF of PTK?
I read about chop chop attack and how it is used to decrypt packets on a WPA TKIP network, by chopping off byte by byte and bruteforcing the byte to trigger MIC failure. In case of MIC failure, would mean that CRC32 is correct and we get … Continue reading Chop Chop attack decrypting ARP results in multicast traffic takeover only
I’ve been trying to crack wifi wpa2 handshake using airodump-ng and aireplay-ng.
I’m using alfa awus-036acs adapter.
sudo airodump-ng wlan0
sudo airodump-ng –bssid MAC ADDR of AP –channel 1 -w capture wlan0
and (tried both)
sudo airep… Continue reading aireplay-ng –deauth never finds BSSID available

What is for GTK key in 4 way handshake while PTK exists?
I have been checking Pairwise and Group Transient keys in a network for security. I understand
PTK is derived from = PMK, AP nonce (ANonce), STA nonce (SNonce), AP MAC address, and STA MAC address
This means that every client will have a d… Continue reading Wpa ptk and gtk in detail
I have a question in particular about WPA’s Enterprise versus Personal without discussing the specifics of WPA2/WPA3.
I’ve encountered quite a few situations where the Personal version of WPA2/WPA3 was used while WiFi access was provided t… Continue reading What is a logical threshold in terms of users or devices to migrate from WPA personal to WPA enterprise?
Perhaps an unconventional comparison. If we ignore device compatibility for a moment and compare security features of WPA3(-three)-Personal with WPA2(-two)-Enterprise. Which is most secure and why is it? Not just in terms of encryption str… Continue reading Is WPA2-Enterprise a more secure protocol designed to protect WiFi communication compared to WPA3-Personal?
In South Korea, I’ve seen a couple of public Wi-Fi networks advertise a "secure" option. Stickers on public buses in Seoul and the captive portal login page for unencrypted Wi-Fi instruct users to connect to a secure option (e.g….
