Crazy Danish Hacker uses GSM sniffing techniques to correlate cell tower interactions and infer a target device’s approximate location: a demonstration of how the GSM protocol leaks location metadata by design.
Final episode: end-to-end SMS cracking. Feeding captured GSM bursts into Kraken, recovering the A5/1 session key from the rainbow tables, and decrypting the target SMS in plaintext.
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.
