In the footer text on the [Contact](https://www.charliechaplin.dev/contact) page of the site, we can see a reference to a possible LinkedIn group, and we're given some search text, which is handy.
The easiest method is to search by "C3D" on LinkedIn and filter by "Groups".
You will find a group that is clearly what we are looking for, and the owner is yours truly.
In the Experience section, you will see an indication upon an event called "Top Hat Development Night"
Use that text to create a search on LinkedIn and filter by Events.
There you'll find the event we are looking for.
In the event description, there will be the flag:
`uiuctf{pr0f3s5iOn@l_bUs1n3sS_envIroNm3n7} `
