crackle
crack Bluetooth Low Energy encryption
TLDR
Crack BLE encryption from pcap file
$ crackle -i [capture.pcap]
Crack with specific LTK$ crackle -i [capture.pcap] -l [ltk_hex]
Output decrypted traffic$ crackle -i [capture.pcap] -o [decrypted.pcap]
SYNOPSIS
crackle [options] -i input.pcap
DESCRIPTION
crackle cracks Bluetooth Low Energy (BLE) encryption. It exploits weaknesses in the BLE pairing process to recover encryption keys and decrypt captured traffic.Requires captured BLE packets including the pairing exchange. Works with BLE Legacy Pairing.
PARAMETERS
-i file
Input pcap file with BLE traffic.-o file
Output file for decrypted traffic.-l ltk
Long Term Key in hexadecimal.
INSTALL
nix profile install nixpkgs#crackle
CAVEATS
Only effective against BLE Legacy Pairing (Bluetooth 4.0/4.1). LE Secure Connections (4.2+) are not vulnerable. Use only for authorized security testing.
