  • Its important to remember that the vulnerabilities always existed, we just know about them now. We have no idea how many of them were being quietly exploited before now.

    There is no point being mad at AI for the avalanche of CVEs, if anything we should be mad ourselves for not prioritising security review of the code. Many of these issues probably could have been found before AI if we as an industry were willing to spend the resources doing the audits. But we werent willing, and now we have to pay for our sins.




  • That doesnt change anything about my original point. They are conflicting missions, whether you add certain or not.

    And no matter what you call it, backdooring ghidra defeats the point of both, it means no one will use it, which allows malware to run rampant. (Ghidra was released during the height of the cryptolocker craze, it allowed reversing those crypto lockers to be done by anyone, effectively neutering many of them).

    And when it gets caught its immediately attributable to the malware division, which they dont want either.

    There is zero point backdooring ghidra. Now XZ? *sshole? Thats the level of sophisticated backdoor I would expect from the NSA.



  • Only true if they can abuse the backdoor, if its tied to NSA infrastructure (which a competent backdoor would be), they couldn’t use it. There is also precedence, the Germans didnt hesitate to publicise that Angela Merkel’s phone was hacked, they could have used the malware to feed false information instead. Stuxnet was exposed to embarrass the US/Israel.

    Cyber security companies would also have no qualms about publicising it. Finding a NSA backdoor would put them on the map, and they have no use for a backdoor.



  • Go to any cyber security conference. Check out the CTF teams, Ghidra is used everywhere.

    Can you prove that there is a backdoor? Remember that it is freely available, and if China, Russia, NK or any other nation state could find a backdoor, they would be shouting it from the rooftops to shame the US.

    I dont doubt that the NSA could have seeded a backdoor in an open source project, but I very much doubt they would sign their name to it…


  • I dont know what you mean by that. Do you mean that the NSA would leave a bug in accidentally? Or intentionally?

    Accidentally is definitely plausible, they are only human after all.

    Intentionally would be incredibly stupid. The offensive side of the NSA spends billions developing malware that can’t be easily found and attributed to them. Inserting one of those malwares into a piece of software they have publically claimed ownership off completely defeats the point. If they wanted to backdoor an open source software, why wouldn’t they do it anonymously…







  • Coating would work, but it needs to be permanent, because you can’t easily recoat it. Glass can be recoated on the other side. Dunno how anodising and etching would work, do you get the same color when you etch, or do you get raw aluminium?

    I suppose if you scanned the plates in a flatbed scanner that might be even contrast, I was thinking of using a phone camera, and assumed it would be near impossible to get an even lighting across the QR code.


  • Etching aluminium might not photograph with enough contrast to pull out the QR code.

    Laser etching glass might be worth a look. You can increase the contrast fairly dramatically with black paint, which can be cleaned and reapplied without damaging the glass.

    Is it 1-2kB uncompressed? Because compression will help, the smaller you get the data the larger you can make the QR pixels. You can also split it into 20x100B chunks, and then as long as you number the slides you can rebuild later.

    Also, ecc-h only gets you 30% recovery, duplicate or triplicate slides could increase that even further.
