      @typhoonfilsy @dguido yeah, quote I heard from @nedos for pulling SE is €100k ...still totally within budget for FBI. If they actually cared

      @thegrugq @typhoonfilsy @nedos I think you're off by an order of magnitude, at least. $1mil lower bound + risk of failure still present.

      @nedos @thegrugq if you adjust to local rates + add overhead, $100k quickly becomes $1mil. Still think you're underestimating challenge too.

      @dguido @nedos @thegrugq I think it's gonna be more 5k and less 1m. Couple million in gear amortizes pretty fast.

      @dakami @nedos @thegrugq gear or not, most of the labor has to be repeated for each phone. It scales poorly, which is what ARES was about.

          @dguido @nedos @thegrugq Is it significantly more custom work to extract data versus just decap and photograph? Doesn't seem so...

          @dakami @dguido @nedos @thegrugq yes there is, you don't "photograph" it (unless it is a masked ROM), you need active EM or laser probing

          @dakami @dguido @thegrugq it’s entirely repeatable per device generation. Like I said once you do the PoC it will be like cracking nuts.

          @dguido @dakami @nedos @thegrugq this is about scaling issues and probability of data loss IMO. They want reliable and repeatable process.
