John LeClair@john_leclair·
I just gave a talk at Hackfest Quebec on EMFI Fault Injection this past weekend. During that talk, I shared some of my lower cost devices in my reverse engineering arsenal. One such device is very affective and only costs around 10 dollars. What do you have on your reverse engineering bench ?

@davepl1968 I always used a floor jack or scissor jack and piece of 2x6 to do my transmission bench-pressing for me. I needed my hands to keep the rust from the chassis out of my eyes.

@ChShersh Turbo Pascal rocked ! Borland tools were so much better back in the day. OWL was soooo much better than MFC. But alas .... Evil Gates prevailed. #linux

@ArchVillequebec Always irritates me seeing the souvenir shops within The Walls with cheap Chinese crap - each with the same items.

@john_leclair Sieur John! Born near my 1608 Habitation, I see. Vex not over the merchants .... Lower Town was ever a bustling hub of trade, though beaver pelts held more virtue than modern trinkets! Even the grand Maison Chevalier must adapt. New France endures!

@felix__augusto @RaminNasibov one would hope and think it was that easy - but as we know - feature creep and bored engineers inject garbage into a design. Hence my desire for a physical power switch.

@john_leclair @RaminNasibov That's a really great point. Clearly wouldn't work! You could absolutely hardwire in some form of a killswitch though. Just like we're starting to look for phones with manual kill switches for your data,gps, etc - the same can be said about computing! You just created a market!

@john_leclair @RaminNasibov Have you tried pressing the power button for more than 3 seconds? My laptop immediately turns off, bypassing shutdown, etc, no drama, just off.

@john_leclair @RaminNasibov This can be done very easily. I could write you a simple script that would do this. I bet money if you go into grok and tell it exactly what you just said, tell it your device specifications, and ask it for code for a program to do that - I bet it works. Try it

@My1xT @Booleans_Things @RaminNasibov I actually exaggerated. 😱 I did have a laptop a long time ago that was soldered in. But it might as well be if I have to remove 15 Torx screws...

How to catch an engineer: Step 1: Place oscilloscope. Step 2: Wait.

@Zackktually @RaminNasibov When Ubuntu (or probably Windows (haven't used Windows in years)) gets massively scrogged - I can hold the power button down on my laptop until practically the end of time before it shuts down
