Hmm. How would ET know the English language (never mind any other terrestrial language) a-priori to enable him/her/it to write a message in HTB{s0m3_t3xt} format?
printable or otherwise.
sampriti is a madman for blooding this as fast as he did. Took me 2 days to wrap my head around this. Feels good though.
Now I know why we can’t find a way to communicate with strangers from space. Thanks @sampriti for little nudge
any nudges, i’m lost ! 
I could use some pointers on this one. I tried common image steganography techniques and none seems to work. Thank you in advance!

thanks @Kucharskov for nudging:)
