SAMBA: Detecting SSL/TLS API Misuses in IoT Binary Applications

Demos

Here is a example of analyzing the SSL/TLS API misuse in the IoT binary applications

Intra-binary analysis

  1. load the target binary with IDA Pro

  1. Run the API call sequence analysis

  1. SSL_get_peer_certificate and SSL_get_verify_result are used, so perform further return value analysis with "2_SSL_API_Misuse_Detection_SSL_version openssl-v2.py"

Inter-binary analysis (conducted on a macOS laptop)

  1. Uncompressing the firmware

  2. configure all the python scripts in inter-bianry folder with correct pathes and set the value of file_name in test_find_cross_file_ssl_bdg_only.py to the target binary (i.e., relayd in the example firmware).

  3. run the inter-binary analysis

    python3 test_find_cross_file_ssl_bdg_only.py
