      Ever wondered what’s in hw ethernet jack style implants? Notice it has a few more than 8 pins. Parents came from communist country, and defected to avoid their regular bugging of their own staff, so I grew up finding bugs. I think they mistakenly shipped me the wrong Raspi 3b+pic.twitter.com/GyR9bCb4Ek

      That is a perfectly normal Ethernet connector with POE (http://files.edac.net/A70-112-331N126.pdf …). Get the part on Farnell, or have everyone else do it for what matters, dismantle it and you will find the same contents.

          No not really. It boots from the network without cable. it boots from the network without a cable at different speeds depending on what non-network thing you plug into it.

          Yes, yes really. You're having paranoid delusions again. Everything in your photo is in the datasheet. Also, poor magnetics.pic.twitter.com/Fy6oarFfBU

          Considering confirmed sigdev "enabled" devices and chipsets these days I think everyone should follow @dragosr example, regardless if it is the case here or not, at least let him finish first or it will come across as gaslighting.

          It's not gaslighting when it's real. Telling people to be paranoid about perfectly normal things does nobody any good. We've already gone through this and it didn't end well. If he *actually* found an implant or credible evidence of one it would be a different story.

          Asking about suspicious things on Twitter is good. Immediately jumping to conclusions and shouting "implant!" is bad. Ignoring all the subsequent replies from experts that tell you what you're seeing is normal is mental illness.

          I’m not immediatey jumping to conclusions. Just trying to explain the code that shows up on airgapped boxes. The fact that they are compromised is certain, just need to figure out how.

          When BadBIOS happened and you were "certain" you were compromised, all the evidence you showed ended up being perfectly normal stuff. I don't recall a single shred of hard evidence for any malware every coming from that story. Which is the same thing that's happening this time.

          I’ve provided BIOS samples to folks from identical boxes before and after. The BIOS modifications consisted of modified ME blobs, and about 100 new variables including installing a new PK (using a hilarious AMI “do not trust” sample key) and other carts.
