A compromised business mailbox can expose internal conversations, enable fraudulent messages and create additional risks for customers and employees. Fast action is important.<\/p>\n
If you can still access the account, create a strong new password that has never been used before.<\/p>\n
If the same password was reused elsewhere, update those accounts as well.<\/p>\n
Attackers sometimes create forwarding rules to silently copy incoming messages to another address.<\/p>\n
If unauthorized messages were sent, inform affected employees, customers or partners.<\/p>\n
Business account incidents should be reviewed at both the mailbox and server-security level.<\/p>\n
Suspicious IP addresses and repeated failed logins may provide useful information about the attack.<\/p>\n
