Ciao a tutti, Hola a todos, Hello everyone

Well I begin the challenge to taking an piece of code.

74 1 8 19 7 63 74 6 1 63 12 53 16 22 37 39
74 8 92 3 105 6 8 12 63 53 7 1 13 7 105 39
         22 8 105 13 39?
and with my script in python I checked the frequency

4 8
3 74
3 7
3 63
3 39
3 105
3 1
2 6
2 53
2 22

Is it the way just ? I don't know....I'll try with an combination:rolleyes:

Seems it:

My decryption is:

WHOKNEWCHECHEMISTRY WOULDCOMEINHADY TODAY ? CONGRATULATIONS, YOUWINAPENETRATION TESTINGSTUDENT COURSE.

so should be

WHO KNEW CHECHEMISTRY WOULD COME IN HANDY TODAY ? CONGRATULATIONS, YOU WIN A PENETRATION TESTING STUDENT COURSE.

I tried with a simple substitution cipher where each letter was assigned a number and with an analysis of frequency of letter more common in English. I didn't found any words good:blink:

I'm sorry:(

Managed to crack the code? Here's the answer to last week's brainXploit 9:

What cipher was used? Well, like we said, it's quite ELEMENTary - and it gets much easier once you're solving it by a TABLE! ;)
