Russia hid spy hardware in the walls of TechEx, an Ukraine defense company that builds drones. They don’t really explain what it is beyond “wire tap”, so let’s do a quick analysis on the hardware to configure out what it does! 🧵1

Replying to @IceSolst
It's poisonous. I have colleagues who reside in Israel who I deeply respect. Likewise, I have colleagues who reside outside of Israel, but live in 'Middle-Eastern' countries, who I deeply respect. Inevitably, regardless of any shred of objectivity brought to the metaphorical table, you will be labeled: - Zionist Pig - Baby Killer - Supporter of Genocide Conversely, you will be labeled: - Brainwashed by propaganda - Terrorist supporter - Anti-semitic Writing this statement in of itself will result in someone commenting something derogatory in nature. Writing I do not want to argue will result in people stating: - You're a coward - Staying silent supports genocide - Staying silent supports terrorism It is extremely polarizing. Even reviewing the comments on this post illustrate some of the points I've made. Beside these points, as much as this will irritate some very passionate people, I do not believe I can effectively comment on something I do understand in totality. I choose to (mostly) stay on topic and focus on topics I believe to have a good understanding of which is primarily malware and how to babble schizophrenic nonsense on the internet.
