Another story on the spirit of wk93. TL;DR I DOS'd the whole campus network for some beers.

In highschool teachers had this blackboard system (a sort of moodle) and we used to have really lazy teachers who only read the PowerPoint presentations and made us take notes. One day I was fed up with their bullshit and figured these lazy ass professors wouldn't "teach" crap as soon as there was no internet connection...so the race was on...

10 minutes before the bell rang a friend and I managed to break in into a computer lab, I booted up Kali and searched for the access points, 3 routers through the building all with CISCO OS.

I figured they had all the default configs, time was running out so I decided to Smurf the three access points with the lab's IP range, scheduled an automatic shutdown in 2 hours and blocked the PC. The bell rang and as predicted, no internet, no class, my friends and I used that free time to go to a bar (on a Monday afternoon).

Funny side note, since the 3 routers were down the whole network collapsed, no cameras, no access control, no faculty network or any network. We kept doing it and every time we did campus security would be desperately searching for someone with a black hoodie.

My last wk93 story, the time we discovered school faculty was spying on students and we uncovered student's deepest secrets.

I call it, kiddiegate.

So if you've read my past rants you've noticed I did some pretty childish and reckless stuff with my highschool's systems when I was younger, but nothing compares to this thing.

After resetting the sysadmin account pwd on some machines it occurred to me I could write a keylogger to capture teachers Moodle accounts and so on, I decided to try it out on a regular lab computer first.

Imagine my surprise when I found a hidden keylogger already installed! I couldn't believe it but then I thought, what if other PC's have it? So I recruited my mates and teached them the process to check if a PC had been infected...ALL PCs were, over 30 computers we checked had been logging for over 3 months! That damn sysadmin! >:[

We were shocked and angry, but then I thought "hey. . . My work has been done for me, better take advantage"

So we did, we extracted each log and then removed it from the PCs along with the keyloggers. There were hundreds of records and then one day we started snooping into the fb accounts of some students (we shouldn't have) we uncovered so many nasty, shocking secrets...

One of the school's lady's man had a drunk one nighter with one of our gay friends, the most secluded and shy guy was sexting like crazy with 15 chicks at the same time, things like that...we promised to never say a word and deleted the logs.

After that we didn't do much and continued highschool as every teenage minor should, getting drunk and avoiding responsibilities, though we could never see many of our classmates the same way. The sysadmin was fired shortly after I graduated, no reason was stablished.

I want to clear out we were minors and laws in my country weren't clearly stablished at the time plus no harm was ever done. I don't condone hacking or any kind of illegal activity, just thought I'd share.

Long rant ahead.. so feel free to refill your cup of coffee and have a seat 🙂

It's completely useless. At least in the school I went to, the teachers were worse than useless. It's a bit of an old story that I've told quite a few times already, but I had a dispute with said teachers at some point after which I wasn't able nor willing to fully do the classes anymore.

So, just to set the stage.. le me, die-hard Linux user, and reasonably initiated in networking and security already, to the point that I really only needed half an ear to follow along with the classes, while most of the time I was just working on my own servers to pass the time instead. I noticed that the Moodle website that the school was using to do a big chunk of the course material with, wasn't TLS-secured. So whenever the class begins and everyone logs in to the Moodle website..? Yeah.. it wouldn't be hard for anyone in that class to steal everyone else's credentials, including the teacher's (as they were using the same network).

So I brought it up a few times in the first year, teacher was like "yeah yeah we'll do it at some point". Shortly before summer break I took the security teacher aside after class and mentioned it another time - please please take the opportunity to do it during summer break.

Coming back in September.. nothing happened. Maybe I needed to bring in more evidence that this is a serious issue, so I asked the security teacher: can I make a proper PoC using my machines in my home network to steal the credentials of my own Moodle account and mail a screencast to you as a private disclosure? She said "yeah sure, that's fine".
Pro tip: make the people involved sign a written contract for this!!! It'll cover your ass when they decide to be dicks.. which spoiler alert, these teachers decided they wanted to be.

So I made the PoC, mailed it to them, yada yada yada... Soon after, next class, and I noticed that my VPN server was blocked. Now I used my personal VPN server at the time mostly to access a file server at home to securely fetch documents I needed in class, without having to carry an external hard drive with me all the time. However it was also used for gateway redirection (i.e. the main purpose of commercial VPN's, le new IP for "le onenumity"). I mean for example, if some douche in that class would've decided to ARP poison the network and steal credentials, my VPN connection would've prevented that.. it was a decent workaround. But now it's for some reason causing Moodle to throw some type of 403.

Asked the teacher for routers and switches I had a class from at the time.. why is my VPN server blocked? He replied with the statement that "yeah we blocked it because you can bypass the firewall with that and watch porn in class".
Alright, fair enough. I can indeed bypass the firewall with that. But watch porn.. in class? I mean I'm a bit of an exhibitionist too, but in a fucking class!? And why right after that PoC, while I've been using that VPN connection for over a year?

Not too long after that, I prematurely left that class out of sheer frustration (I remember browsing devRant with the intent to write about it while the teacher was watching 😂), and left while looking that teacher dead in the eyes.. and never have I been that cold to someone while calling them a fucking idiot.

Shortly after I've also received an email from them in which they stated that they wanted compensation for "the disruption of good service". They actually thought that I had hacked into their servers. Security teachers, ostensibly technical people, if I may add. Never seen anyone more incompetent than those 3 motherfuckers that plotted against me to save their own asses for making such a shitty infrastructure. Regarding that mail, I not so friendly replied to them that they could settle it in court if they wanted to.. but that I already knew who would win that case. Haven't heard of them since.

So yeah. That's why I regard those expensive shitty pieces of paper as such. The only thing they prove is that someone somewhere with some unknown degree of competence confirms that you know something. I think there's far too many unknowns in there.

Nowadays I'm putting my bets on a certification from the Linux Professional Institute - a renowned and well-regarded certification body in sysadmin. Last February at FOSDEM I did half of the LPIC-1 certification exam, next year I'll do the other half. With the amount of reputation the LPI has behind it, I believe that's a far better route to go with than some random school somewhere.

fancy coding standards

So I've been using this website that loads terribly and after sending the dev some emails on how he should reduce the amount of page requests to reduce the load time, I got this response. Anyone with moodle experience care to explain why one should have 200+ css requests before a page loads?

I'm adding content to a schools moodle for an online CS course I am creating. The dev thought it would be a good idea to have 250+ page requests so I get to wait for 10seconds everytime I click the next button.
Still no response to my email asking him to uglify and concat.
At least I'm getting paid by the hour.

"Hmm, I have one hour left to hand-in my complete program via Moodle. I can still do something.
Let's implement a cheat when a user types 12oatmeal at the menu."

Moodle is the worst shit ever

This semester, we have a lecture called IT Security by a guy, who absolutely know his subject.
Nevertheless, he wanted to show us that sha256 is broken by an existing collision. (Google that, fellow ranters!)
There are two pdf files by google researchers, that show the caption „SHAttered“ both on different backgrounds, although they give the same SHA-hash.
He then tried to share us these two files by moodle and wondered, why he uploaded the same file twice.
Guess what happened? The moodle backend checks new uploaded files for their ... hash ... and then decides, weather to upload or the file is already existing. So, it did just a new symlink to the old file.
Ironic, that an exercise, that should show us sha collision failures on sha collision 😃

tl:dr
i fucking hate that professor for whom i have to work on laboratory project right now.

reason#1
the project is using a stack full with java. JavaScript. react and some weird facebook api of which i have no clue about. not to mention the server side of this application which uses tomcat (ok its java after all) and sql.

well that wouldn't be not so bad if...

reason#2
we wouldn't have to fucking debug his mistakes he put into the fucking prepared code AND his fucking useless instructions how to set up the project for eclipse the first time. not to mention his fucking requirements which make no sense

oh yeah im a student. i can always go and ask him for help if i need any...

reason#3
i have another 70% mandatory course at the same time and that fucker refuses to upload hos sheets in moodle and answer even one fucking question via mail. not to mention no support if I am there unless i have eclipse setup. even through the projects should be build using gradle...

reason#4
oh. and have i mentioned that this course is only about design patterns? uts not like we could see several of them in a java only application. no we literally have to learn java itself. gradle. nodejs JavaScript Extended for react which i have no clue about at the moment... and yes i especially mentioned gradle and nodejs beccause we have to set shit up and not only use a script.

reason#5
and all that wont even give us a grade. no ita simply a pass or fail part of the module which the course is part of.

have i also mentioned that the whole shit should be done in 20 hours according to the schedule

It's my first rant. So please ++1 me.

Now my rant:

In this semester I had a subject about system architecture. In this class, we must learn Java script, C# (and ASP.NET framework ), PHP (and Zend Framework 2), but in the classes is taught only UML and patterns. In the moodle of the subject we don't have any information about any of the languages and if we ask the teachers they don't know anything.
And we need in 4 weeks do a work with a widget in javascript, 2 Asp.net mvc, 1 asp.net web api. All with authentication.

So we are all fucked

LOL I just found out the deloton adware is installed on my schools website (WordPress) and also they don't use HTTPS on the Moodle server to which hundreds of people sing in every day. Tomorrow I'll go with some friends to the admins and show them all the shit they've been doing. This will be fun!

So you guys know how universities can sometimes have TERRIBLE old software that hasn't been updated for years, and sometimes you want to do a specific process over and over again so you end up automating it, now, we've built a tool that automates downloading projects from the University Moodle website, and we would like to publish it for other students to use.

Problem.

The University is using SSO.

And so far we've made the application to work by observing the network connections over the Android app version in order to extract the cookie session, now imagine that we publish this little tool, and tell people to do those exact steps, of course it's impractical and misses the whole point of the tool itself for being easy to use.

So, where can I read more about SSO, how can I figure out what the University uses? And if I had to reverse engineer this, where should I start? (It goes over 4 pages and I'm not able to capture those requests to even figure out what's going on)

In short is there a guide where you take a university SSO service and build on top of it? I couldn't find anything that is helpful.

Hey everyone:)
Im working on a small project on moodle. Is there a way to link outcomes and competencies and how ?

Chrome vs Firefox ram usage. Chrome running 1 tab (moodle) and Firefox a blank startup tab. I was genuinely surprised to see Firefox using more than 50% more compared to chrome. Both browsers are 64 bit and chrome has perhaps 10 extensions while Firefox only 5

Everytime I feel like looking at something on Moodle.org... the site works.

Everytime I *NEED* to look at stuff on Moodle.org.... the site dies. Every. Time. FFS.

And no, there isn't "something wrong with the internet". -_-

To whose of you who contributed code to Moodle LMS in the past: what do you think of this LMS and the way they ( core developers ) treat non-core developers?
