Ask HN: Can anybody please explain this hack?
Suppose you were having a conversation with a demonstrably capable hacker and it doesn't go so well, after which, the following happens:
- You hear what sounds almost like a power generator going off in the distance, except it's a "softer", more "bass"-boosted and buzzing sound and doesn't have that final "crackle" exploding sound at the end; more like a slowed-down version of the sounds leading up to that final "generator blew out during the storm" sound
- During this, the light in your room noticeably dims for a brief moment, but then goes back to normal (the nearby cable TV box if fine, not rebooting or anything)
- However, your laptop (Mac, if it makes a difference) that you reasonably recently updated the battery for at a reputable, licensed location inexplicably shuts off (no warning, no fan overheating sound (no fan at all, actually), not a lot of apps open to stress processor or memory
- Your laptop at this moment was not just fully charged, but also plugged in
- The laptop self-reboots, whereupon you notice your battery charge is now inexplicably "0%"; opening up the settings panel, the graph shows that your laptop was in fact fully charged until just a moment ago when the charge inexplicably nose-dived to "0%" (when that outdoor "power generator humming buzzing sound happened and the light dimmed)
- This part didn't happen exactly this way and I don't want to go into details of how it did happen, but let's say something like this happened: Upon your laptop rebooting, let's say there is an open sticky note or a notepad app that inexplicably opens also and something like the following was typed in: "Hope you saved your work at (hour)(minute) on (day)(date)" – so basically you do not have doubts that "this was no accident"
My question is 2-fold: (1) How is it possible to instantly discharge your laptop's battery so that it goes from 100% to 0% in a split second, and, more importantly (2) how is it possible to rewrite your laptop's "whatever" so that if the battery suddenly has 0% charge, the hardware is reset to ignore the fact that it can draw power from also being plugged in?
I'm not expecting (though I'd love) any "As a hacker who used to do just this sort of thing to people, I know exactly how they did it" answers, but ANY ideas about how this may have been possible would be greatly appreciated, thank you.

- GWBullshit 1y agoAssuming you're serious and not just trolling, could you at least describe if it's possible to protect against such things and how?

- GWBullshit 1y agoPerhaps you can, but can we please stick to the subject?
- GWBullshit 1y agoOK, "I see"; lmao and all that good stuff
- bigyabai 1y agoYou gotta relax. Your submission history suggests that you jump to conclusions as a chronic habit. It's harmless to people like me who like playing with gulliable folks, but probably quite debilitating for you whether you realize it or not. You might want to talk with a doctor about it.
- GWBullshit 1y agoYou're not helping out very much and quite frankly now you're sounding a bit immature and come off as bragging that you're on the peak of the Hill of Stupidity of the Dunning-Krueger curve ("*I'VE* never had such experience, therefore it can't be possible and you're probably delusional, so "take meds, lol"). Thanks for your replies, I guess, but I have certain experiences with certain things so I know what I'm talking about, despite it seeming like "jumping to conclusions" to you; honestly you come across as a know-it-all college sophomore with that reply.

- GWBullshit 1y agoAlso, (if it makes any difference): I've had hacks happen before where the method used was to instantly spike the processor's heat to force an emergency shut-off (couldn't find any indications of sudden spikes in application memory/processor usage that would have explained this). But this time the laptop temperature was perfectly normal and there was no indication of sudden heat spikes.
- azail 1y agoNice creative writing exercise. I hope you're not expecting serious answers though as this is rather daft, like a plot off a low budget film.
- GWBullshit 1y agoA response from an account created just an hour ago (at the time of this reply) for seemingly no other purpose than to respond to this post with low-effort, ad-hominem crap is definitely something I will be taking very seriously.

- GWBullshit 1y ago???
- GaryNumanVevo 1y agoI can send you some good recommendations for CO and methane other gases
