Moving away from Arch Linux Part 1: Systemd
Why I want to abandon my current distro and move to another. Stories of systemd breaking my systems and getting its tendrils into places that I'm not comfortable with. Ooh! Not there! aaaaah!
Low Cost SimpliSafe Attacks
Earlier this week, Dr. Andrew Zonenberg of IOActive published a security advisory and blog post describing weaknesses in the SimpliSafe home security system. He showed that components of the system, such as the keypad, transmit unencrypted radio signals that can be captured and replayed. He also pointed out the significant problem that SimpliSafe devices are physically incapable of being reprogrammed with improved firmware that might address such vulnerabilities.
I know Andrew and have great respect for his reverse engineering and hardware hacking talents. He implemented a replay attack by making small modifications to SimpliSafe devices, monitoring and controlling them from his own hardware platform. To demonstrate...
Диагностика Imprecise Bus Faults в микроконтроллерах Cortex-M3/M4/M4F
При разработке программ для систем на микроконтроллерах серий Cortex-M3/M4/M4F программисты, бывает, сталкиваются с исключениями ядра, когда программа останавливается в бесконечном цикле в обработчике FaultISR. Как правило, попадая в этот обработчик вы уже не можете определить что произошло, т.к. стек вызовов в отладчике уже не отображается. Еще хуже, если в регистре Fault Status появится ошибка Imprecise Bus Error. Вот про диагностику этой ошибки я и расскажу.

In this video of Michael Ossmann’s presentation at ToorCon 2015, he demonstrates how helpful it can be to use a combination of both SDR and non-SDR tools for reverse engineering wireless systems. Michael uses both HackRF One and YARD Stick One to reverse engineer a wireless cabinet lock.

The code from the presentation is in Michael Ossmann’s stealthlock repository.
