[Samba] Ransomware?

[gimili17]

Would something like this help?  I put a bunch of junk pictures and 
other files in a samba share that everyone has access to.  If I modify 
them in any way, I get warned.  I was thinking it might warn me so I 
could prevent it spreading to backups.


#!/bin/sh

$MY_EMAIL="some at email.com"
$MY_DIR=/home/shared_to_everyone_via_samba/pictures_for_test_sub_folder

while inotifywait -qre modify "$MY_DIR"; do
     #play a sound on server
     play -v .3 /home/warning.wav
     #send an email
     mail -s "Possible malware" $MY_EMAIL </home/warning.txt
done
