A useful chart on what type to use for flags in C/C++ depending on your D&D alignment:

Glitches in games, especially used for speedrunning, are one of the most fun aspects of hacking to watch! As an example, check out this video "How Speedrunners BEAT Hollow Knight Silksong In 10 Minutes!" by Abyssoft www.youtube.com/watch?v=M6Jn...

One of my favorite projects just hit a HUGE milestone of 1 million downloads! Kudos to the team and everyone who supported us!

You can write '2' (0x32) anywhere in the filesystem of a Linux-based network switch. How do you get root? That's basically what my talk at GreHack conference was about - enjoy! youtu.be/F4CudbWHZ7Y?... youtu.be/X-ZJH4d2tuE?...

With the newest Black Alps 2025 and GreHack 2025 additions, my printed Paged Out! collection is slowly growing!

Here's some blursed Python code for you: a, b, c = {"alice", "has", "a cat"} print(a, b, c)

Here's a Saturday Python 3 Puzzle for you:

If you've liked my "Linux Terminal: CTRL+D is like pressing ENTER" article (hackarcana.com/article/ctrl...), be sure to checkout @mina86.com's "Is Ctrl+D really like Enter?" (mina86.com/2025/is-ctrl...) :)

Heeey, ncurses/terminfo has a small virtual machine! And if there's a VM, there are CTF challenges :) hackarcana.com/public-exerc... hackarcana.com/public-exerc... (third one coming next week, will be a bit harder)

We've received 50 required articles for issue #7 of @pagedout.bsky.social - this means we're publishing the issue in the few next weeks. 1. Want to get an article in #7? You should write it now and send it in in the next few days. 2. We're still looking for more issue sponsors!

OK, ChatGPT 5 admittedly surprised me in a positive way. I threw a PNG with a (small) Python AST graph at it and told it to reverse it to Python code, and it successfully did that. I have expected it to fail hard, but here we are 🤷.

Friendly reminder that order of operations makes a difference... more so than you think ;)

Lulu (print on demand) is increasing prices by 5% from Aug 1st, so if you were thinking of getting @pagedout.bsky.social #6 there, do it now: www.lulu.com/search?page=...

[Please share with people outside of cybersec] Do you have a horror story when you had to deal with cybersecurity companies / people? This is your chance to vent! → forms.gle/9aX24HrfnEQm... I'm running an anonymous survey to listen to stories and look into the disconnect we sometimes have.

A (not so) short analysis of anonymization schema used in the "Discord Unveiled" paper: hackarcana.com/article/anon...

Poll! What ANSI color types does your terminal support? "\x1b[1;31m3bpp+attr\x1b[m \x1b[91m4bpp\x1b[m \x1b[38:5:196m8bpp\x1b[m \x1b[38;2;255;0;0m24bpp\x1b[m" Reply with screenshot of the output of this string + add OS/terminal versions E.g. Ubuntu 24.04.2LTS, Konsole 23.08.5

Btw, is there sth like (www.web3isgoinggreat.com) but about AI fails?

Paged Out! #6 is out! pagedout.institute Totally free, 80 pages, best issue so far! 'nuff said, enjoy! (please repost to help spread out the news!)

Next Monday I'm doing a 2h webinar on files as seen through the eyes of a cybersecurity researcher. This will cover useful stuff for programmers, more junior pentesters, and other tech enthusiasts who enjoy knowing how stuff works on a computer :) hexarcana.ch/lp/files/?ut...

I'm getting some specific questions about my upcoming training – I'll update the training page later today. This said, I've also recorded a short show-case / case-study of what type of skill one will acquire on my training: www.youtube.com/watch?v=ib4Y...

tmp.0ut Volume 4 just came out!!! LET'S GO! And guess who's article is there ;) 08 .... FixedASLR: .o ELF loader in a CTF task tmpout.sh/4/

I'm running an "Intro to programming and Python" workshop (in Polish) in the evening with Sekurak / securitum and we have over 10 000 people registered. This is definitely and a new record for me!!! If you understand Polish, you can still sign up at sklep.securitum.pl/wstep-do-pro...

A lot of you were telling me I should do my courses in English, so here we go: Mastering Binary Files and Protocols: The Complete Journey hackarcana.com/bin?utm=gyn-b This is an A-to-Z course teaching a fundamental skill in practical IT, useful in cybersec/coding/etc Start Apr 8th

It's been a moment since I've posted sth on my YT channel, so here we go: www.youtube.com/watch?v=jBsV... I'm going here through my "pressing CTRL+D is like ENTER pressing" article – enjoy!

I've written another article, this time on the fundamental reason why we have all these XSSes/SQLIs/etc. At least that's the way I explain it ;) hackarcana.com/article/why-... There's also a CTF challenge for this article (misc60): hackarcana.com/article/why-... Enjoy!

If you like CTF challenges, we've been steadily pushing some of my favorite tasks to my new edu site: hackarcana.com/exercises From top to bottom: Linux RE, 2x JS RE, USB PCAP, ZIP/crypto, DOS/VGA RE, 2x BMP image stegano, 5x BMP file format stegano, Python 2.7 RE, and ROP RE HFGL

Did you know that pressing CTRL+D in linux terminal is like pressing ENTER? (to some extent, of course) Well, I didn't, so after randomly investigating what CTRL+D actually does, I've decided it's a fun topic to write about: hackarcana.com/article/ctrl...

Pro tip for protocol hand-crafting lovers: Having problems sending \r\n on Linux? Press CTRL+V to escape the next key press, and follow it up with ENTER to get \r. CTRL+V, ENTER, ENTER → \r\n

Worth reading!

This one is a fun one hackarcana.com/public-exerc... USB PCAP of a gamepad selecting the flag :) (Dejan, who was re-flagging this task, had to listen to my "back in my days the second thing you've learnt in programming was how to read the state of a joystick!" story. I am not sorry.)

Audio deepfakes will disproportionately affect people with hearing disabilities that rely on cochlear implants. This is the inconvenient reality of AI harms for marginalised groups. www.ndss-symposium.org/wp-content/u...

I've published a new blog post clearing up some confusion about what's what in the realm of securing input received from the user (or attacker): hackarcana.com/article/sani... That's a bit of app security theory for you, but I've seen this asked on job interviews. And it's actually important ;)

(funny, story in 4 posts) I asked Google to change "my" photo that pops up on Google Search's Knowledge Graph, since, well, that isn't me...

Problem with neural networks is that they don't always observer the feature you think they should. Case in point: I know that my tea is safe to drink if the cup isn't full. I've already had some tea, so it's not hot anymore, right? A half-full cup of boiling-hot tea is something I actively avoid.

ICYDK restrictions in PDF (copy pasting, printing…) are linked to encryption, which often uses an empty user password : no password prompt, but the file is still encrypted. So just decrypting the file (via qpdf, pdftk, print to PDF,…) removes these restrictions.

Oh this issue is going to be amazing! If you want to get your article in, you have around 10 more days before we set the number of pages in stone. Btw, know anyone who would like to sponsor Issue #6? pagedout.institute?page=ads.php

There is still a couple more days to submit your 1-page article to @pagedout.bsky.social #6! We're at 41 pages of content out of 50 required. We'll start finalizing the issue when we reach 50. Not much time left, but you can still make it! :) pagedout.institute?page=cfp.php

"Hacker", as we in the bizz know well, carries different meanings for different people, and this can cause hilarious misunderstandings. Yesterday, the second part of an ongoing documentary about issues in NEWAG trains that were analyzed by Dragon Sector was aired. [...] gynvael.coldwind.pl?id=799

Soft deadline for Paged Out! #6 is upon us – 1 Feb 2025 – pagedout.institute?page=cfp.php

If you're following NEWAG vs Dragon Sector suits: Citizens Network Watchdog Poland ("independent, apolitical and non-profit organization in the form of a watchdog & think-do-tank") filed an amicus brief with the court urging the court to dismiss the case as a SLAPP siecobywatelska.pl/od-niedziala...

Legal question: I've been following the Honey/PayPal case, where they are getting class-action-sued left, right, and center in the US. Will we be seeing individual lawsuits and class-action-equivalents in other countries as well? If yes/no – why?
