Detects the creation of user accounts or modifications to sensitive groups (Event IDs 4720, 4728, 4732, 4756) where the account name matches naming conventions typically associated with backup service accounts or elevated administrative roles (e.g., prefix 'backup_', 'bkp_' or suffix '_da', '_ea'). This activity can indicate an attacker attempting to establish persistence or escalate privileges via compromised or newly created accounts.
