Senior Security Researcher, Proofpoint Emerging Threats. Digital Arcanist

I've been doing this cybersecurity thing for the better part of a decade now. Probably longer than that. I'm starting to forget. Time is relative, but it surely isn't kind to my memory.

I'd like to think I do cybersecurity well, but blue teamers collectively get told they're doing it wrong constantly. So maybe I just failed forward throughout my career.

Oh, I wrote a book. Its a good framework for setting up a virtual machine lab. See my bookmarked toots if you're curious.

Finally, I occasionally write about tech/nerd-related things over at https://www.totes-legit-notmalware.site where I expose that I have a short fuse, and no filter.

its been an interesting winter here in SE Michigan. We got pounded with snow in November. It was an icy slushy mess, and ever since then, its been intermittent, but in most cases, not heavy enough to justify the snowblower.
Last year, we didn't get major snowfall till about now (January-ish).

THE INFOSEC EXCHANGE BETTING POOL ON THE CLOUDFLARE OUTAGE HAS BEGUN.

we live in a world now of systems with multiple gigabytes of RAM. Multiple Multi-Gigahertz processing cores. SSDs with blazing I/O. Even in the face of moore's law, multi-core systems, and even ARM-based multi-core systems are still performing extremely well. All this, and even in spite of the business world's best effort, broadband has, in general, improved greatly.
So how is that, the way forward with web protocols is "my dogshit-performing JS framework has lead us to web servers that have to use UDP to perform at scale." and not "javascript was a language created in a handful of days, maybe we should re-visit that."

goodness. one of the times that HTTP Traffic wasn't on port 80 (port 9090) that I didn't have to re-write the snort rule with no content modifiers. Miracles do happen. #Just_Rule_Writing_Things

I mean, I get that its supposed to be this funny Sun Tsu moment about not interrupting your enemies when they're making mistakes, but also, it should be a cautionary tale about the kind of mess that AI integration well truly is. "We're going to make better on-system assistants" should have been the call, as opposed to "Let's shovel money at nvidia to make our own AI datacenter."

remember when operating systems stayed the fuck out of the way and didn't try to either nanny-state you or jam fucking ads into every orifice available?
I almost understand why arch users are the way they are.

kinda sortta. It takes a lot of effort to build deb packages and get them to the point where they are just fire and forget. Then the packages all require maintenance to update, and packages it depends on, as well as packages depending on that package need to be checked for compatibility.
Its a pondorous thing, and the trade-off for pre-packaged binaries: You get the convenience of: Its in a central location, managed by a trusted entity, and I don't need CPU cycles or systems know-how to compile it. Give me a laundry list of things to install for the thing I want to run, and boom, its done.

good thing I'm dogfooding the installation instructions. The version of cmake in ubuntu 20.04 isn't new enough to compile one of the libraries I need to make snort 3 work. Had to add instructions to add the kitware apt repo for 20.04 to use cmake in order to build vectorscan.

Game enjoyed a Very Positive Steam review rating. It got review bombed. 14,000 negative reviews just yesterday.
Have a feeling they aren't going to drop the PSN requirements. Probably publisher demands, considering how popular the game is right now.
Only thing I think would make them reconsider/make it optional would be for steam to start issuing refunds.
Its really interesting to watch something like this unfold.

"But wait, there's more!"™
Community leaders have called the users entitled and said it takes 120 seconds to set up a PSN account.
Completely disregarding regions that don't have PSN access.
"Use a VPN!" you say. If Sony detects VPN usage, your account gets banned. If they detect failed password login attempts, your account can get banned.
Allegedly some users are posting screencaps that Sony demans gov issued ID to create an account. Photoshop is a thing, I can't verify that. I didn't need to in the US.
But even better yet, is that someone high up at arrowhead was mentioning that this was to help "benefit from the Security of the PSN".
Allegedly PSN has had security problems. Recently.
Edit: Neither of these are PSN *specifically* but Sony networks have been getting popped by ransomware gangs recently.

Game had so many players that the devs would put major goals like "Kill 1 billion bugs in 7 days", and fuckers had it done in like 3 and a half days.
So, recently, they announced that they're bringing back the ability to link your PC game with PSN accounts. Only, its not optional, its mandatory.
Which is all well in good, but this directly contradicts Sony's policy (that they changed literally yesterday) that states that PSN linking isn't supposed to be mandatory for PC releases.
Which is also all well and good, but the PSN network doesn't exist or allow users from some countries. They support 60ish countries? Not even the entirety of the EU is supported.
This means there are a lot of people who bought a game who are out the 40 bucks this game cost.

I imagine most of you have better shit to do than wax philosophical about video game news, but that's why I'm here: I'm a no-lifer.
Helldivers 2 is a pretty popular squad-based FPS. Think of it as Starship Troopers. Its basically that. Fight bugs, or fight autonomous robots.
It developed quite the following. The developer, Arrowhead Studios (I said publisher earlier. Pretty sure Sony was the publisher) had a lot of problems during initial launch. Turns out the game was very popular on launch. So much so, they disabled PSN account linking until they could scale things and work on stability.

I have never witnessed a publisher set their good will on fire as fast as Arrowhead has in the past 24 hours.
