Packet capture tool aircrack2/21/2023 ![]() ![]() ![]() ![]() It should be noted that a pre-shared key can be from 8 to 63 characters in length, making is impossible to crack the pre-shared key (Aircrack-ng, 2010).Īuthentication is basically the same between WPA and WPA2. The handshake between the access point and the attacker does reveal some information, though, when handshaking is connecting a client to a network. In WPA/WPA2, the key is not static, so collecting (initial vectors) IVs (unlike WEP) does not speed up the attack. WEP can leverage statistical methods to speed up the cracking process, however, only brute force techniques will work against WPA/WPA2. In this article, we outline the use of a tool called ‘Aircrack-ng’ used by security professionals to access secured WiFi.Ĭracking WEP Versus WPA The approach used to crack the WPA/WPA2 pre-shared key versus WEP differ significantly. But, what about our home? While you may have followed our best advice to select a password for your router, implemented WPA/WPA2 encryption, it is possible, with help, to access these also. We don’t give a second thought to accessing a free WiFi spot in a coffee shop or otherwise since it enables us to maintain access. Introduction Given our increasing need to stay connected via social media, email and, therefore, have access to the Internet, the availability of free, open WiFi access points in institutions, shops and in some areas, city-wide access points has become the norm. Aircrack-ng is a widely used tool with capabilities to crack WEP and WPA. ![]()
