  1. Ok, so which one of you is using the knowledge gained from #38C3 @positive_sec talk "BlinkenCity: Radio-Controlling Street Lamps and Power Plants" to play with the streetlamps in my town?

  2. At #38c3, we presented our #BlinkenCity research, which started as a fun art project idea, and ended up as a plausible European #blackout scenario.

    TL;DR: Some European countries use unencrypted and unauthenticated #longwave radio to steer parts of their renewable power, enough to potentially cause a Europe-wide blackout.

    The control signals can be sent with just a #Flipper Zero over short distance, or via self-built transmitters over a long distance (e.g. using a kite to lift an antenna wire).

    The system is also used for street lamp control, allowing for a scaled-up “Project #Blinkenlights” art installation that transforms an entire city into a screen (for astronauts).

    The company operating this system has threatened us with lawsuits and (now publicly) denies the risk.

  3. Ein Geheimdienst baut Pager mit Sprengstoff, vertickt sie an die richtigen Leute. Sendet auch noch die richtigen Signale und die #EFR glaubt, dass sowas nicht möglich ist.

  4. The #BlinkenCity talk at #38c3 had everything I love about a good #CCC conference talk: Fabian Bräunlein and Luca Melette were up to some harmless mischief but ended up uncovering a real-life clusterfuck that could severely harm us all and are now getting threatened with serious legal action.

    It turns out that large parts of the European #powergrid are controlled by an unencrypted radio control protocol and we're cooked!

  5. There are #CCC conference talks and there is stuff like #BlinkenCity. I am watching this with my jaw dropped! I'll provide a link later. This stuff is un-fucking-believable.
