the new PS4 jailbreak is sort of hilarious 

I love my programing looking like it was written in 2005 and horid function names.

Did you say your name is Ed instead of Low Level Learning for the first time? Classic Ed move to sneak that in

I believe any system can be jail broken, via the ethernet port....and of course some smart developers,

going off on a limb here but i would say they wrote the code in that manner to make it harder for people to read on purpose.

That "im not a cop" at the end makes everything 10 times more sketchy 🙂

Probably equally as insane as the tweezer hack on the wii, was doing a man-in-the-middle attack on the pcie bus of the ps4. The same team that did the tweezer hack on the wii used an fpga board(connected to the ps4 apu) and another PC(where the ps4 “chipset” was connected) and connected those 2 using 115200baud serial(kinda downgrading PCIe to 0.00002x)

Man. When I hacked my PSP, I did by loading images of eggs to it that make it crash lol Those were the day am I right

Bro, that was cold, but so true... hahaha

don’t talk about when the design of Go as a language looks like it came from

I came to write this 😂

"buf" is still common and that's a good thing

But think of all the bytes you could save by shortening your variable names!

Even in the 80s we were trained to use descriptive variable names. Did we do it? Arguably. I mean, buf isn't that bad.

The code shown for the exploit used the exact same naming conventions.... It's not that bad

​@@VonCarlssonDepends on the context. If there's more than one, such as I see daily in rendering code, ibuf vbuf isbuf is very fun to read and decipher....

Sony dev in disguise

The achilles heel of the PS4 has really been relying so much on open source modules, especially FreeBSD for the kernel. Every time there is a critical CVE, it's open season for another jailbreak. Microsoft has the privilege of being able to build around in entirely closed source environment. It makes reverse engineering a much more daunting task.

It also gives you dev mode for $20

The polar opposite is the Wii U, which can be hacked with an SD card and the web browser.

​@@tbuk8350 Wii is easier to hack and way easier to set up storage

Probably because it's a POS no one is really interested in. Being able to softmod a PS4 opens easy piracy to a LOT of less technical gamers.

That’s most likely because the PS4 kernel is a modified OpenBSD kernel. They likely just didn’t disable it

​@@ryanilari3537 It's based on FreeBSD, but yes, this was just inherited functionality. Weirdly, the PS4's OS is supposedly based on FreeBSD 9, which is from 6 years after this was patched, so I'm guessing they didn't fully rebase on FreeBSD 9 but kept code around from the PS3's OS (also partially based on FreeBSD), which is basically contemporary with the vulnerability.

Exactly what I was thinking like pppeewhat

Maybe they do and that API makes use of the device as a persistent location.

waw, a course covering all those aspects of reverse engineering sounds interesting. Where can i find this course??

Im also interested on that course xD

@@hriad I would also be interested in that

@@nicolasfuchs3072 yeah cough it up buddy

OP, please bless us w/ the course

It sounds like there are 11 kinds of people 😉

legally, the console hardware is yours, but the software on it is licensed to you by sony, and sony can revoke that license at any time (though I am not aware of any instances where they have done this to anyone). given that the software is installed in such a way that sony hopes you will never be able to modify it without their consent, the hardware is also effectively controlled by them in practice unless you find a way to get past their protections, hence what is said in the video that is to say, ownership means what it always has, in a sense, but software companies keep trying to find ways for that to be less useful to you. another good example is with modern games; technically you don't own those either, they're also just licensed to you, and that license can be revoked at any time. I believe it's technically been that way from day 1, but it's only within the last 10-20 years that publishers have gained the ability to actually enforce that through modern DRM but also remember: if buying isn't owning, then piracy isn't stealing :)

@@powerLien Wait, even the OS IS GIVEN under a license?! Wow, I want to read the T&Cs on this one!...

@@Brahvim windows is like this too. if you change the hardware in your computer too much without reinstalling windows, it will revoke itself, because microsoft bases the validity of a windows license on the particular hardware configuration windows sees when it's first installed technically, you don't really own any software that you don't make yourself, even if it's free. what matters is the terms under which it's licensed to you. ex: linux is licensed to you under the GPL, which in practice means it's free forever

Eh, Linux is free and fully yours

@@powerLien amen to that

there has been a lot of other exploits before this one, iirc 4-5 years after release

@@klairm9097 flatz jailbroke 1.76

PS4 has been jailbroken many times before on earlier firmwares. This one is just the latest one that works until 11.00. Also Sony is constantly patching the software with updates, this bug could have been patched at any point between 2013 and now, but it wasn't because no one knew it was in there until now.

True, but what he was referring to is that this exploit was already in the wild in 2006, which is why it the claimed date is roughly correct. There are plenty of other exploits using the same vulnerability, just with different hardware, or ordered increments. Honestly can't wait till PS4 stops getting updates, so we don't ever need 2 worry about patches screwing with custom ecosystems anymore.

@@elvendragonhammer5433 Might be a long ways off. Even the PS3 had a recent-ish update. But definitely share the sentiment!

They do; they just hope the defenses last long enough so they can get to their next iteration without someone breaking it and defeating DRM etc. It's why I suspect Microsoft allowed developer mode on the Xbones, those who want to write games and apps can do so, without having to exploit the whole system, leaving that area only for the pirates to investigate.

The PS3 let you officially install Linux. I think they removed that because they were worried someone would use the Linux environment for jailbreaks... But ironically, taking away Linux created a much bigger incentive to jailbreak the console, that is, bringing Linux back 😆

@@DigitalDiabloUK Wasn't the Switch broken, like, Day 1? You can't defend anything with an OS

Yeah, steam is this whole "piracy is a utility issue" thing, provide a good service and it goes away mostly.

Eventually though steam servers will one day shutdown, and then do we really own anything?

MVG is a king. He gets down and dirty with the code, but this channel is even lower-level than that!

agreed!! would be awesome to see a low level oriented console hacking series

although, Windows apps are meant to run, and be updated for years. Game consoles, not so much.The only coders looking at this code are trying to hack the console! It's not nearly so desirable to have readable code in the console world (unless you're porting a particular game to other platforms)

Ah the good'ol "too broken to be lockpicked" strategy

This comment deserves more likes 😂

Yeah I've been unironically wondering about this. It's nice that software is less likely to be taken advantage of by malicious third parties, but what do you do when it's the vendor themselves who is the malicious actor?

I'm curious as to how much we'd be able to achieve with this. Cause I'd love to install Linux and Steam on my PS4 and use its GPU for essentially PC gaming lol.

@@FelipeV3444 sadly the gpu driver for the ps4 is not shared by sony so on linux you will be using the integrated graphics of the cpu which is horrible for gaming

​@@btwiusearch2linux has been ported to ps4 (currently only for older jailbreaks like 9.00) and it has gpu drivers. also ps4 doesnt even have dedicated graphics iirc

@@SanekGamer007 sorry i meant gpu acceleration it doesnt have that

@@SanekGamer007 i also had linux on a jailbroken ps3 and that too had gpu driver but no graphics acceleration but some one somehow programmed a graphics acceleration driver for the ps3

You get charged by the character when you read it. The longer the name, the more it distracts you from seeing the shape of the code and understanding what it actually does.

@@hobbified only if the code itself is short, neatly written, and contains no bugs. I've spent way too much time deciphering unreadable mumbo jumbo in my career just because some bright minds wanted to use up the entire alphabet for variables instead of treating a programming language as, well, an actual language 😅

Short variable names should only be used within very short functions. People are making out like you write all go code like this. Calling an integer you are manipulating, i, in a 3 line function for instance. If you are using short variable names in any other way, you are doing it wrong.

@@repairtech9717 ideally yes. however, in my dealings with the arbiters of Go style from my time at Google, and from reading the stdlib, there was a strong cultural norm towards shortness for its own sake, even at the expense of what I would judge as readability.

@@repairtech9717 when writing Go code at Google, in my experience the style reviewers for the language strongly pushed authors to shorten variable names in most situations, even beyond the “just a few lines” case (which, in that particular context, I would not find objectionable)

"If it was hard to write, it should be hard to read."

You can search for Critical Program Reading (1975) to see just how old it is. People have been struggling with unreadable source code since the dawn of programming and have tried to figure out solutions. Part of it is the background too. If you're used to math then single character variables often feels like the cleanest solution, but in Java it should be a sentence.

In 2006 Perl still saw regular ( yet dwindling use). Php owned the web and jQuery wasnt really on the scene yet. I think a lot of people are confusing 2006 and 2014...

@@DavidCowie2022 some developers seem to think that “security through obscurity” is a coding style and applies to job security.

That was the whole pitch of the Ouya way back in the day. Wound up not being very successful, but I always admired the ideal behind it. It's just very difficult to be successful in the modern console space. there's a lot of open portable devices though, so there's something at least

We have that - it's a regular computer XD

That laugh hurt.

Memory exploits often cause the ps3 to crash. The risk for bricking is too high so they are not ideal.

Not accurate at all ​@@wingedzero

Entirely different processor, definitely won't work. Ps3 was a weird console that developers hated because it was so weird.. same reason it's so hard to emulate even to this day.

thank you youtube is trying to end my career ong

I mean, they have x86_64 CPUs, you just would need drivers for GPUs (same arch as AMD desktop GPUs) and the wifi chip, and some more firmware.

from what i know, you can run linux on the ps4, if you have the firmware 9.00 and below jailbreak, i don't know how it is for the 11.00 one.

Not, if you round up

Why the hell would you run it with gpt, just run the file directly

Your variable names don't exist after compilation, so no need to be terse for that. If you're talking about memory limitations of the developer's computer... In 2004, it wasn't unusual to have a GB of RAM. The contents of a text file really didn't bother computers by then. Maybe this was an issue in the 80's, but not in the 00's. Half Life 2 came out in 2004. Crysis would release just 3 years later. It really wasn't the dark ages anymore. Computers were fast and had plenty of RAM for software development. I've worked with a guy who still named variables like that in 2016 or so. He was getting close to retirement and just stuck in bad habits. People just didn't think as much about code maintainability.

@@Niosus Those are definitely good points! I keep forgetting how 20 years ago means 2004 😭 I'm getting too old! 🤣

@@Niosus I was basically gonna write the same comment, I was a kid back then but I think our home PC had a 128gb hard drive and 512mb of ram around that time. I think the variable names do exist somewhere in interpreted languages so maybe it was a concern for late 90s Java/JS/PHP programmers? More likely to be habits taught by people who programmed even earlier tho

Yeah, it's not so much hardware limitations, since the names don't stick around after compilation, but more because C programmers for a while had a habit of writing this way and that got passed down to many developers. A lot of older c programmers came from assembly which is where some of it stems from. Sort of the opposite of Java devs 800 character names, LOL

Wew mate my childhood 386 machine back in the early 90s had more than 100MB of hard drive space. I'd very surprised if even back then people worried about how much space their variable names would take up

Who told you
