I don't think I heard that. I believe the reason why they encrypted the data was because they wanted to keep the data accessible while Evil Corp was still in the dark. They aren't going to delete the data and then encrypt it because it would raise flags if someone saw it in the deleted state.

Neither of those are a reason to encrypt rather than just overwrite, which is easier.

Maybe saying that the data is encrypted is just a measure to have some leverage down the road, whether or not it's legitimate leverage, in that fsociety could say "do [X] and we'll decrypt" or some poo poo. There could be information in the data that could be used for other things. We clearly haven't seen the end game yet, so who knows. Who cares, really? This a Great Show and I can't wait until S2. Also, my girlfriend called it that Darlene is Elliot's sister the moment she was on screen for the first time. She said "they look too much alike, she has to be his Sis".

They encrypted it out of a sense of dramatic flair. "Your data is still there... but you will never see it again!  "

They probably stole the idea from ransomware like crytolocker. I bet it'll be a plot point in the next season where there is a "mystical genuis" or something that can break the encryption.

Popcorn Gun hasn't been handled by all the party guests, so despite the best attempts to destroy solid evidence at the arcade site through heavy traffic there's still that concretely tying Darlene and Eliot to the whole bag of cats.

they specifically used RSA encryption, then destroying the key. 'encrypting their poo poo for them with your key' is in the conciousness lately with the insanely successful Bitlocker ransomware. but i think this is how they get out:

You need that key to encrypt *and* to provide continued service of post-encrypted materials while it's encrypting so there's no noticeable service interruption at Evil Corp. edit: Or maybe they just didn't bother. What is the size of the data that catalogs most of the world's debts anyway? How long were they encrypting? Less than 3 days?

Last year National Australia Bank had a massive outage that lasted over 10 days when a system mangled their main data stores. Millions of transactions were corrupted and it took a while for them to recover everyone's banking details to a usable state. ATMs, direct debits, credit cards, and the works were all offline and many people had significant troubles with everyday banking. Additionally it also caused problems for companies that were using NAB payment gateways for their e-commerce business. My dad was affected, but had money in non NAB bank accounts to see him through. Not everyone was lucky. Although NAB were willing to compensate people that incurred fees as a result of their systems not working. This was just Australia, and less than 20% of the population (so less than 5m accounts maybe). I'd say that something happening to a super conglomerate would be far more explosive. If anything, Mr Robot downplayed the insanity an event like that would cause.

Subjunctive posted:More interesting to me, If the point is to not have it be recoverable, though, there's no reason to encrypt at all. Just overwrite with zeroes or a random pattern. So there must be some circumstance under which fsociety would reverse the encryption, and someone must be safeguarding the key. Many possible plot hooks in that space. Actually deleting stuff from a harddrive to the point where it isn't recoverable takes quite a lot of time. I don't remember the specific number but I think the military standard is to overwrite the data around 30 times.

If you instead crypto the entire drive slowly while keeping the encryption key in memory and passing all file reads to the encrypted sections through your rootkit which silently decrypts it, you will have the time necessary to get EVERYTHING. Then you delete the encryption key, write over it a few times for good measure, and everything goes tits up instantly.

The cut to the popcorn machine while where is my mind by the pixies was playing (the song that plays after jack kills Tyler by shooting himself in the head in fight club) seems to heavily foreshadow the involvement of the gun in the fate of Tyrell. Not gonna say Tyrell is definitely dead but things don't exactly look good for him. As has been said Tyrell is a real guy. No one has really pointed to it as evidence that Tyrell is a personality but the strongest evidence of Tyrell being a personality of Elliott is Tyrell's private conversation with Mr Robot in the limo. A plausible explanation for that conversation is that when Tyrell met with Mr Robot and said he knew his secret he was referring to the fact that he knew Elliott (Mr Robot) had set up Terry Colby. Anyway that's my Tyrell hot take. I'm glad someone made American Psycho Fight Club with fairly realistic computer hacking thrown in, Christian Slater as Brad Pitt, and a story that seems ready to span multiple seasons without totally falling apart or becoming repetitive.

If they encrypted everything they could shut off access to the data without deleting the key while overwriting the data inside the encrypted volume. Then the system becomes unusable as soon as the decryption stops running but the key isn't actually deleted until multiple overwrites have completed. That way there is an instant, nearly irreversible shut off of access to the data hopefully followed by the time needed to completely destroy it. As someone mentioned this does leave the system open to having the key extracted from memory by an attacker like the dark army but if the overwrites occurred the data is gone anyway. White Rose has a corporate rivalry with ecorp anyway, it seems like he wants to see them brought low and has little interest in saving them.

If I'm not mistaken, it was Whiterose and the dark army that did the hack on the live data centres in China. FSociety only had to tamper with the offsite tape backups. Whiterose would have already had the encryption keys as they are the ones that perpetrated the hack in the first place... Unless I'm missing something?

I'm not sure if there were live datacenters in China. Maybe just backups but I don't recall. The live datacenter they called out was the one in the USA (at Dulles I think?) and the hack there was perpetrated by fsociety activating server CS30 (the server with the worm that Elliott left behind).

Formal procedure in our shop for classified touched storage is one wipe with random pattern, degauss, followed by removal by authorized vendor to physically destroy. One of the things that points to the strength of this show is the number of directions it can go to explore plot points or observations left open. Elliots sanity, who is and isn't really there, and what roles specific characters are playing as cogs in an overall scheme are all valid directions for further exploration. I sincerely hope that at least some of what Elliot is seeing is valid, the complete daydream angle, even if well written, would personally be a huge letdown.

DoD standard where I live is a single pass unless the drive is smaller than 15GB or was manufactured before 2001 (and then it's 3-passes.) Drives of this age could be of such low density that you may get off-track data, but it has never been proven on anything that is commonly in use these days. I don't know anywhere that uses disks of that vintage, and you certainly won't see them in a top-tier data centre. Disks rated at Top Secret or similar clearance are treated differently. They are usually physically destroyed, and the only reason you'd wipe them beforehand is to protect against loss or theft of the disks on their way to the press/furnace.

Yeah. And by physically destroying the disk you aren't relying on the minimum bid contractor doing his job right in the wiping process. Easier just to melt the thing to slag.
