There are several warning signs that could indicate your business email has been compromised. These can include unusual login notifications, unfamiliar devices or locations appearing in your account, emails being sent without your knowledge or unexpected password reset requests.
You may also notice emails disappearing from your inbox, unfamiliar forwarding addresses or rules being added to your account. If customers or suppliers tell you they've received suspicious messages from your email address, this could also be a sign that your account has been compromised.
