Boop VS CyberChef

There's also Boop, which is open source: https://github.com/IvanMathy/Boop

I've been using Boop, it's pretty good for, json, yaml, datetimes, hashing etc! Missing a lot of what you've mentioned, but might be able to get some more ideas from it!

Another alternative to DevUtils would be Boop. Or CyberChef, for that matter (web, but available for local and selfhosted installation).

in addition to what's already mentioned, https://github.com/IvanMathy/Boop to convert and format things instead of googling for a converter every time

Also, Boop.

Boop: Collection of utilities/extensions for developers

Though may I suggest checking out Boop? I love how minimal it looks. Maybe you can implement a minimal mode later?

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...
