Did you know that the ‘Nigerian prince’ email spam still brings in over $700,000 USD per year? It’s one of the most successful scams campaigns to date.

Solution

We are given a text file which contained a usual scam email like message. I tried common stuff like viewing the hexdump, trying whitespace steganography tools like stegsnow etc.., but nothing worked. So I searched “text file steganography” and came across the link Steganography to hide text within text. There was a link to https://www.spammimic.com/ in the answer. Decoding the message using spammimic, we get the flag.
