How Do I Crack Satellite and Cable Pay TV?

Follow the steps taken to crack a conditional access and scrambling system used in millions of TV set-top-boxes across North America. From circuit board to chemical decapsulation, optical ROM extraction, glitching, and reverse engineering custom hardware cryptographic features. This talk describes the techniques used to breach the security of satellite and cable TV systems that have remained secure after 15+ years in use. Topics include: chemical decapsulation and delayering of ICs in acids, microphotography and optical bit extraction of ROM, binary analysis using IDA and homebrew CPU simulators, datalogging and injection of SPI and serial TS data, designing and using a voltage glitcher, extracting secret keys from RAM of a battery-backed IC, analyzing hardware-based crypto customizations, studying undocumented hardware peripherals, MPEG transport streams and non-DVB-standards, QPSK demodulation, interleaving, randomization, FEC of OOB (out-of-band) cable data. The result is knowledge of the transport stream scrambling modes and knowledge of the conditional access system used to deliver keys. Strong and weak points are identified, advanced security features implemented nearly 20 years ago are compared to modern security designs. A softcam is designed and tested using free software, working for cable and satellite TV.

When Governments Attack

Targeted malware campaigns against Activists, Lawyers and journalists are becoming extremely commonplace. These attacks range in sophistication from simple spear-phishing campaigns using off the shelf malware, to APT-level attacks employing exploits, large budgets, and increasingly sophisticated techniques. Activists, lawyers and journalists are, for the most part, completely unprepared to deal with cyber-attacks; most of them don’t even have a single security professional on staff. In this session Eva Galperin and Cooper Quintin of the Electronic Frontier Foundation will discuss the technical and operational details of malware campaigns against activists, journalists, and lawyers around the world, including EFF. They will also present brand new research about a threat actor targeting lawyers and activists in Europe and the Post-Soviet States. With targeted malware campaigns, governments have a powerful tool to suppress and silence dissent. As security professionals we are in a unique position to help in this fight.
