    Breaching a Digital Safe

    OH LOOK BOB IS GOING TO SHOW US HOW TO USE A MAGNET TO MOVE A SAFE LATCH OR BANG ON IT WHILE PULLING TO HOP A SOLENOID. Not today my friends, but that sure sounds fun, and already done. Most nights, I try to get in a walk. That is, when it isn’t Surface…

    Be Sure to Drink Your Ovaltine

I don’t think I’m spoiling anything here since this runs 24 hours a day on a ton of stations in December, but if I am, go watch it first. One scene is especially interesting to folks interested…

  • More Locks = More Security?

    More Locks = More Security?

    This morning, I went for a walk and came upon this rather formidable cell tower enclosure. Usually these things are behind a chain link fence — this one is behind a block wall and has a stout gate. After the 2022 substation attack, I can appreciate seeing stronger protection to critical infrastructure. In this case,…

  • Kroger: A Case Study in Security Theater

    Kroger: A Case Study in Security Theater

    Security Theater, simply put, is what you see when you go to the airport, or a court house, or perhaps even your local gas station. A well designed and functional security system should be seen, not used. I would, 100 times over, rather somebody who wants to do me harm, see my security cameras and…

    Alarm System Part 3: Security System – Dumping the EEPROM

    If you’re coming here looking for the dump, I can’t share it. I don’t know what the laws are on this and it feels pretty DMCA-ish. Sorry. This Blog is part of a Series! Check out the rest if you haven’t already: So, the EEPROM programmer arrived today. For that, I’m excited. And nothing warms…

    If you are looking to understand how combination locks work, or you already have access to the inside of a PO Box, you’ll probably enjoy Part 1 a lot more. This one gets into decoding the lock from the outside. Before we start, lets just look at how ornate this damn door is. WOW. So…

    Decoding USPS PO Box Combinations – Part 1

    A few weeks ago I took a trip to a local antique mall here in Texas. It’s been a few years since I’ve been to one and last time was to find old school padlocks to pick. I found this USPS PO Box door (presumably box #60563) for sale for $20, along with several others.…
