. I search for it and found some informations:
- a song : https://www.youtube.com/watch?v=cPkE0IbDVs4
- some article about the last Avengers movie : https://www.insider.com/avengers-endgame-robert-downey-jr-i-love-you-3000-2019-5
- a IT virus : https://en.wikipedia.org/wiki/ILOVEYOU
The last point is the most relevant for our search. With its name and github, we can found the source code https://github.com/onx/ILOVEYOU.
We got a love letter that correspond to our challenge : https://github.com/onx/ILOVEYOU/blob/master/LOVE-LETTER-FOR-YOU.TXT.vbs.
We need to found now what are the number and how we can combine the both?
Some looking on the dcode.fr website, we found a cipher using number as word/letter references for a text/book.
We enter all the source code as book to use and the number as indexes. We got the flag : RTCP{I10V3H0WBROKENMY3MAILZR}
