CyberChef VS reveal.js

Then we take the encrypted text and use CyberChef to decrypt it.

Let's go to CyberChef and insert our pieces of evidence.

A parameter was changed from '2AMBCgIQBg' to 'CgIIAdgDAQ%3D%3D' which is just the correct base64 encoding they should have been using the entire time.

I don't think this was a hostile action by Google, I think someone just added better input validation for security reasons and it accidently broke the bad requests they were sending.

❗This is indeed the flag, but the text is encrypted with Base64. Usually, the presence of padding character "=" indicates that's Base64 type of encoding (but that's only one of the hints). To decrypt it, we can use CyberChef. Copy-paste the text and we either:

It uses a combination of magic bytes (like the `file` command), entropy analysis and character frequency detection to determine whether an output is likely to be of interest to the user.

The file type mechanism is written here[0]. There's a list of all signatures we detect here[1].

I think this can be deciphered using CyberChef...

There are a few GitHub repositories on my account where you can find some of my presentations, created with reveal.js, a framework for creating presentations using HTML and Markdown.

I did not come about trying it out yet but Reveal.js looks very interesting to me and I think I will use it once I find the time to learn it...

I think i'm not in the same ballpark but i really really liked reveal.js

it's reveal.js for those unfamiliar

https://revealjs.com/

I've not tried it myself or seen an example, but given the structure, it would seem like Reveal.js might give you the the sort of functionality you're looking for while having many other affordances one might look for in a digital and/or online zettelkasten.

As an aside, learning Reveal.js ( https://revealjs.com ) would be something for longer term growth, but if you don't know it now and you have a time limit, its not something to get into. If you do know JavaScript, HTML and want to give it a try (don't spend more than 2h without results - time boxing the "this doesn't work" is important) you could host it in a GitHub repo and point a browser at it.

Most of these use https://revealjs.com/ to create static HTML and Javascript files for display in a browser.

In the end I settled for reveal.js which as far as I remember has this notes functionality (although I never used it). It creates an html for you which I find very convenient for any presentation over internet. It has some learning curve but it's not too complicated.
