Episode 15: installing Kraken on the Linux server and running the first sanity-check queries against the A5/1 rainbow tables. Confirming the cracker is operational before pointing it at captured traffic.
Episode 14: obtaining the A5/1 rainbow tables used by Kraken to break the GSM stream cipher. Where they come from, storage size, and how they map ciphertext bits to key candidates.
Episode 13: installing and configuring the Linux server that will host Kraken. Storage layout, network setup, and preparing the environment for the A5/1 rainbow tables.
Episode 12: setting up ESXi as the hypervisor for the GSM lab. Preparing a Linux VM to host the Kraken rainbow-table cracker and other heavier tools.
