Hash Browns

Password-cracking Points - 400

Thanks to your help, we have found evidence relating to the unF0r7un@t3s at the location you uncovered in  in "(un)F0r7un@t3". We apprehended a couple subjects.  It turns out they were planning something bigger, and that was only the beginning.
We found a drive containing password-encrypted, and managed to find the passwords hash, located in hash.txt below.
We have reason to believe that the password starts with the name of a city (in lowercase) in France (which is the country they attacked last), and ends with up to 7 numbers.  For example: paris1337 (don’t try that that’s not the flag).  Please decrypt the password.

Since it says name of a city in France we downloaded fr.csv, a file containing the biggest cities of France. Then we wrote exploit.py to brute force compare hashes with the one from hash.txt.
