They did bcrypt right, the "salt" isn't a secret, it's a randomized string to prevent people from being able to reuse brute force attempts across multiple passwords, and it is supposed to be available everywhere the hash is. Unless they had literally one salt that everybody shared, which I don't believe is the case. Any hash dump is going to be associated with some number of stolen passwords because an awful lot of people use passwords that are in the top 10k most common passwords, or passwords that were stolen in a previous breach- in fact, twitch users specifically do it so much (because they trend young), they used to have a problem with people brute forcing common passwords & credential stuffing attacks on the front door until the identity team made some stupid AI thing to lock account aggressively if anything looked weird.

Your password will not be stolen if you have practiced good password hygiene up until now, but that is not a good reason to stop practicing good password hygiene.

What's the difference between having the salt from the list of hashes, and having the salt from the source code? The leak has hashed passwords and the source code. Why would it matter which of those two spots the salt is in?

If you have the source you know how the salt is used, so you can just start plugging in passwords to generate hashes and see if anything matches the leak. Once you have something you have access to the account using that hash, and it doesn't even have to be the original password so long as the hash matches.

Sorry, I misunderstood your intent. It doesn't matter where the salt is stored per se, but storing it with the hash is generally indicative of better security practices because it becomes a whole lot easier to have unique salts for each hash that way. The purpose of the salt is to slow down anyone trying to exploit a leaked hash table, and keeping your salt in your source code means you're probably reusing your salt a lot which makes things less secure.

Having the salt from the source code would imply that twitch uses a single salt for all users (bad, defeats the purpose of using a salt) but I don't think any salts are stored in the source code, and it would be a tremendous amount of work to gently caress up in that manner with bcrypt. Going over it this morning I haven't seen any evidence of salts in source code, I have seen a lot of aws aurora & firehose credentials. I was aware of the latter & it's too bad they didn't leak my 2016 jira tasks to the security team about it ;)

Everyone already had the source for how the salt is use, it's located here: https://github.com/golang/crypto/blob/master/bcrypt/bcrypt.go

And if anyone discovers a fast mechanism for brute-forcing bcrypt passwords, they probably have better things to do than hijacking twitch accounts. Generally speaking when a properly functioning hash dump gets leaked, it goes like this:

code:
* Hey, I can pare down a credential stuffing attacks to just the ones that I know will work. 
 Does the website have some protection against credential stuffing attacks?
  * No -> I could already do a credential stuffing attack without this dump
  * Yes -> It will probably stop me even if I have a known-good subset
* Hey, I can locate users who use the top N most common passwords who have not already had their passwords breached
 Is that a real subset of users? 
   * No -> Then this dump is useless
   * Yes -> No it isn't
* Hey I can spend a few thousand dollars brute forcing a single admin user's password and then do other stuff with that and not make the leak public
  Are there any protections that would stop me from logging in as an admin from BFE?
   * Yes -> I will never recover financially from this
   * No -> Hey now we're in business
  Are there any mechanisms by which my breach will be discovered after I log in, limiting my gains and causing the company to act before the leak is made public?
   * Yes -> I will never recover financially from this, and also why was I doing all this again?  Surely there's something more useful I could have done with this leak before getting caught.
   * No -> John loving Madden
It's just not a good way to use your resources.

Stone drums are the very earliest, and not bad especially when you first break into chemistry and liquid production, since you'll have maybe a dozen chems you'll be juggling and it's good to have a place to put them.
EnderIO fluid tanks are pretty good too, and work well with most input/output sources (both in world and in UI) so it's always good to carry one or two of those around, too.

When 1.18 comes out, I hope we get a few simple QoL mods too, because I've gone so deep in the hole of heavy modpacks and tech progression I think I just need to reset with a mostly vanilla dive. Fabric's looking promising for a lot of that, but all I really need is a few nice decorative mods and maybe some performance boosters and I'll be golden.

You've got the hard part done it sounds like! The biggest hurdle for me was the number of diamonds needed. It was beyond excessive and I spent the last ~8h or so just sending T4s in to get the dense diamond ore, and the T1s in to get the pristine diamonds to build and send the lair and shard MMs. I was never short on omnium really and neutronium timing lined up pretty well. I didn't have a huge amount of waiting like a lot of people did, since apparently it takes a full day of a T3 fusion reactor to make enough neutronium, though I would have had a big delay (and finished sooner) if I stockpiled more diamonds. I had to build out that bolted-on processing array to handle the diamond ore load.

You need ~800k regular diamonds ~20k (~300 t1s worth) of exquisite diamonds to get to tank.

It's less that and more that I already have a lot on my plate between games and work so if it's still a ways off from stable release I won't feel too bad continuing to wait for it while I work through the things I have going on.

Is getting a virus from a sketchy Minecraft download actually a thing?

I'm in a mentor role with some kids, and one of them messaged me in a panic tonight saying that he had gotten a virus from a Minecraft mod and wanted help fixing it so he didn't have to tell his parents he'd hosed up the computer. He claims that after downloading some mods a pop-up appeared saying he was being hacked, and that the entire computer then stopped taking commands from him and his Minecraft character started moving around on its own. At my urging he pulled the plug on the machine and hasn't turned it on since. I know he was doing stupid poo poo in search of mods/hacks because he admitted to getting one from loving 4shared of all places, but he's also a bit developmentally delayed and extremely not computer-savvy, so I have to take his descriptions of anything technical with a big grain of salt. That said, does this sort of thing happen in the community? If so, is this something to be seriously concerned about, or is it just a dumb prank that will succumb to safe mode and a virus scanner?

We're playing Roguelike Adventures and Dungeons. I've almost 100%ed the book, currently working on the super-late Impetus tech from Thaumic Augmentation. I've done so much stuff in TC that I've never tried before.

I've leaned incredibly heavy into Thaumcraft, with Electroblob's for more supporting buffs that TC doesn't really offer. I've got golems (my first time getting them to do gently caress-all of use) handling my Mystical Agriculture crops, incredibly powerful armor, dragonbone weapons, and have completed my first Eldritch Citadel and stripped it for parts for my tower. The endgame of Thaumic Augmentation is kind of annoying (the enemies are super aggressive and the warp builds up), but the gear looks awesome and offers a lot of great additions and fun tools overall. I really like Impetus, it's a cool throwback to the old Aura system.

Though, I am fully sick of Crimson Cult ambushes and other irritating warp effects.

Basically, I'm focusing on magic and introducing mods and gear in my tower, they're learning modded MC (one's done Sky Bees with one, one's pretty new) and exploring. I'll probably be teaching TC and probably Embers, which I'll move onto once I successfully set up Impetus generation and storage. Next up is probably going into a

However, we've been having a lot of fun. First up is my increasingly "is, uh, that guy alright?" wizard tower, then the rest of our little starter town and increasingly-populated village.

I've never heard of people getting actual viruses from minecraft mods, but I also don't know anyone that would download a mod from 4shared. Considering mods are effectively extra java code that runs when minecraft loads, you could definitely write a malicious "mod" that is actually a virus and takes over your computer via minecraft. It'd be especially easy to get a virus if you download a file that claims to be an installer for a mod.

I'd take it seriously, but most viruses can be removed via safe mode and a virus scanner anyway.

The most likely result from this is that the kid had his account stolen.

My kid virus'd up our computer a few years ago trying to download an adventure map. I'm sure there are a zillion predatory sites that use minecraft as their bait because young kids aren't going to have learned to play "which of these seven buttons that say download is the real one?".

Depending on how they downloaded the mod, it's completely legitimate - minecraft mod download sites have the most predatory and confusing "click here to download" type ads and malware that I've ever experienced in my long history of modding, so that's what probably happened, it's probably not the mod itself.

As to what they accidentally ran and how to clean it up, uhhh good luck. It can be anywhere on the spectrum from "shady software the cleanly uninstalls when you ask" to "straight virus that hides through anything but a complete flatten and reinstall"

God, this is so true. Apparently the reason he went on sketchy sites is that all the mods he "downloaded from curseforge wouldn't work," so I went there on a completely stock Internet Explorer (yes, he uses IE, yes, it makes me shudder), and oh my god it's a nightmare. I haven't seen the internet unfiltered by uBlock Origin and NoScript for years, so I had no idea what they were up against. I'm reasonably certain I would have clicked one of those hostile links at least once, and I've been doing this for a long-rear end time. I suppose this is a lesson for folks with kids in their lives, either your own or family friends and such: take some time to make sure they're using real browsers with adblockers, you'll save them a lot of time and aggravation, and you won't end up having to unfuck their computers down the line (as much).
