WPA2半握手包破解，不需要传统完整4步握手也可破解，WiFi密码破解

dxa4481/WPA2-HalfHandshake-Crack

This is a POC to show it is possible to capture enough of a handshake with a user from a fake AP to crack a WPA2 network without knowing the passphrase of the actual AP.

WPA2-HalfHandshake-Crack

Conventional WPA2 attacks work by listening for a handshake between client and Access Point. This full fourway handshake is then used in a dictonary attack. This tool is a Proof of Concept to show it is not necessary to have the Access Point present. A person can simply listen for WPA2 probes from any client withen range, and then throw up an Access Point with that SSID. Though the authentication will fail, there is enough information in the failed handshake to run a dictionary attack against the failed handshake.

Install

$ sudo python setup.py install

Sample use

$ python halfHandshake.py -r sampleHalfHandshake.cap -m 48d224f0d128 -s "no place like 127.0.0.1"

• -r Where to read input pcap file with half handshake (works with full handshakes too)
• -m AP mac address (From the 'fake' access point that was used during the capture)
• -s AP SSID
• -d (optional) Where to read dictionary from

Capturing half handshakes

To listen for device probes the aircrack suite can be used as follows

sudo airmon-ng start wlan0
sudo airodump-ng mon0

You should begin to see device probes with BSSID set as (not associated) appearing at the bottom. If WPA2 SSIDs pop up for these probes, these devices can be targeted

Setup a WPA2 wifi network with an SSID the same as the desired device probe. The passphrase can be anything

In ubuntu this can be done here

Capture traffic on this interface.

In linux this can be achived with TCPdump

sudo tcpdump -i wlan0 -s 65535 -w file.cap

(optional) Deauthenticate clients from nearby WiFi networks to increase probes

If there are not enough unassociated clients, the aircrack suite can be used to deauthenticate clients off nearby networks http://www.aircrack-ng.org/doku.php?id=deauthentication

WPA2半握手包破解-不需要传统完整4步握手也可破解

传统的WPA2攻击通过侦听客户端与AP接入点之间的一次成功握手实现。

然后抓到的4次握手协商可用来字典攻击。

这个工具展示了不需要AP真实存在即可完成攻击。

一个攻击者可以仅仅通过嗅探任何有效范围内客户端发出的WPA2探测信号，

之后建立那个SSID名称的AP接入点。

尽管认证将会失败，但失败的握手包已经有了足够的信息被用来字典攻击。
