Forgotten Ruins -OSINT

Hello, this is my first writeup and I hope you enjoy it.
So we have an OSINT challenge called Forgotten Ruins on vulnbydefault.com

How much a person can reveal about himself? connect through nc

first we start by connecting through nc (netcat)

We can log in, and we can reset our password, so that’s what I did

We received an email, and received our first clue

The company policy for passwords is to use 3 things that are important in your life.

Then we can see our second and most important clue

Full Name : Owen Rosz
Username: owenrosz
Email: Owenrosz@vbd.com

Now we have a full name, username, and email
Let’s try searching for his username

We found an Instagram account, which is our starting point

From the Instagram account, we found three things:

1-istanbul
2-Turkey
4-another account: cuteomencat

Based on what we found, we need to identify three personal elements, such as the security questions used by big companies

Next, we will check the@cuteomencat account

We found a text in the cat pic that leads to a Reddit account

We found his DOB (Date Of Birth)

DOB: 7 sept 2013 (edited)

We also found a social link to Pinterest

i love my house number its literally leet so nerdy remember its numbers only

We can see the word leet in the text, so it should mean something
in the tech world

leet = 1337

This is what we found so far

city = "Istanbul"
animal = "Omen"
DOB (years)= "1995–2025"
leet= "1337"

If you think about it, we have two words and two numbers, and from the first clue, we want three things that are important to our target, so here is how it should work

(part1) Omen (part3)
(part1) Istanbul (part3)

So we will have to make a wordlist and start trying all the combinations on nc (netcat)

after some time and hard work

The username was

owenrosz

and the password was

1337Omen2003

It was a bit hard, but I liked it because it simulates a real case scenario, which is awesome if you think about it, but after all, it was a great one and I really enjoyed it
See you in another write-up
