Description

My friend sent me some skibidi data... Can you help me understand his goofy sentences?

A *.docx file was attached.

Solution

*.docx files are actually ZIP archives. We can extract the file and search through its content. Eventually, we find the following file under .\word\img.xml:

<root>
  <person
  firstname="QnNpZGVzVExWMjAyNHt3M19k"
  lastname="M2YzNXQzZF90aDNfc2sxYjFkaX0="
  city="Haifa"
  country="Israel"
  firstname2="QnNpZGVzVExWMjAyNHt3M19k"
  lastname2="M2YzNXQzZF90aDNfc2sxYjFkaX0="
  email="[email protected]"
  />
  <random>6</random>
  <random_float>89.838</random_float>
  <bool>true</bool>
  <date>1986-09-28</date>
  <regEx>helloooooooooooooooooooooooooooooooooooooooooooo world</regEx>
  <enum>generator</enum>
  <elt>Alyssa</elt><elt>Flory</elt><elt>Ulrike</elt><elt>Teriann</elt><elt>Reeba</elt>  
  <Ulrike>
    <age>56</age>
  </Ulrike>
</root>

We decode the Base64 string and get the flag:

>>> import base64
>>> base64.b64decode("QnNpZGVzVExWMjAyNHt3M19kM2YzNXQzZF90aDNfc2sxYjFkaX0=")
