100$ for the electronic components excluding the special Apple tools required to open the iPhone, having extra NAND chips, the time and software to repeatedly attempt a passcode. (According to the article, hundreds of hours when you have a 6-pin)

If you use a 6-pin, there's only a million combinations you have to try, and if you do them in random order you can halve the number of password attempts before you achieve success (average case).
If one pin entry takes 5 seconds to validate, you'd only waste about 58 days going trough all the million combinations.

You can also very easily run these attempts in parallel, so even if you can't make a rainbow table because there's a good salt, you can probably reduce the time needed by a factor of at least 100 by also running it on a GPU.
I feel that this hack isn't really something that the average consumer has to worry about

For "on the spot" hacking, no. But if somebody manages to steal your phone and has the intention to resell it...

Or steal your data or whatever else.

That person would have to be quite dedicated, to think you would probably lose 1/4th of the iPhone price on hardware and software to properly crack it or hell even have the skill to properly dismantle the iPhone and to remove the NAND

But having taken all of that into account it sure could be possible, everything you need is something you could buy from amazon or ebay

Depends on whether there's ways to get payment information or bank details out of the phone I guess, because that's the only way I see this being economical for a thief over just selling it aside from phones of notable people. Still, I see people all the time claiming that some device is "uncrackable", it's important for people to know that their devices aren't completely impervious to being broken into I think.

On that note: This is actually preventable (at the cost of making the devices almost completely unrepairable I assume).
Chip terminals in stores for example (should) have the whole security chip wrapped in layers that delete the secret key when breached.

Phone makers seem to have an obsession with device thickness so I doubt too many will be looking at hardware anti-tampering but it's definitely pretty useful for improving security

And now you've stopped people from repairing their phones, which is bad for a couple of reasons one of them being it worsens the "buy a new one" society we live in.

Securing the NAND chip woudn't make it irrepairable.
Its not like Apple makes their things repair friendly though

I just wanted to mention this :v:
Apple already is all uptight about their hardware so if any company would want to pull off something like securing their hardware it would have been Apple

I was under the impression they meant just opening the phone in general, and meant more than just Apple.

You don't need to make anti-tampering blow up the entire phone if you touch it, some chips even have anti-tampering baked in to various degrees. Not that apple would likely care ofc

Partially. At the very least it would be easier to destroy it if you have no idea what you're doing with the repair, but as a few others mentioned it's possible to secure just part of the board.
