3AM Ransomware Note Detection

This rule detects elements commonly found in 3AM ransomware notes. It looks for the strings "threeam" or "3 am", a specific onion URL pattern associated with 3AM ransomware (e.g., http://threeam[0-9,a-z]*.onion or http://3am[0-9,a-z]*.onion), and at least one of the keywords "encrypted", "data", or "payment". The combination of these indicators suggests the presence of a 3AM ransomware note, likely indicating a ransomware infection or an attempt to communicate ransom demands.
