Quote:A new phishing campaign is underway that pretends to be a list undelivered email being held for you on your Outlook Web Mail service. Users are then prompted to decide what they wish to do with each mail, with the respective links leading to a fake login form.

Recently, we have seen quite a few interesting spam campaigns such as account cancellation notices and alerts about unusual volumes of file deletions.

This campaign is just as interesting as it uses the subject line of "Notifications | undelivered emails to your inbox" and pretends to be a list of email being held on the server for you.
