Hello Angry Employer,

I will not stand for this, it was a simple mistake that anyone could have
made.
If anything, I should blame your company training!
I'm leaking all confidential information, on purpose this time.

Hope you like being the center of attention on infosec twitter!

Hello Mr. imdeveloper123,

Are you kidding me? You leaked company info by making the dot-files you use
for work purposes *public* on your GitHub?
It should come at no surprise that as of the time of writing this email,
you are permanently released from your current job.

Please talk to HR ASAP.

## Solution
We were able to open the file given with Notepad++. Since this was an OSINT challenge, I looked for things that could be found online
in public webpages.

```Hope you like being the center of attention on infosec twitter!```

This line hints to look at the twitter page of **imdeveloper123**. Going to https://twitter.com/imdeveloper123, we find that he has
made two tweets.

The first tweet hints that we should use Wayback Machine to find an old archived version of his deleted blog. Using the Wayback Machine
on the https://iamthedeveloper123.weebly.com/ gives us one snapshot on December 24th. Opening the website gives us the flag.
