A highly targeted phishing campaign, with a Microsoft file platform twist, has successfully siphoned the Office 365 credentials of more than 150 executives since mid-2019.

Second, the initial phishing emails are sent from legitimate but previously compromised email addresses - which cloak the fact that they're attacker-controlled.

The email read, "Please+see+above+document+from[redacted] for your review and let me know if you have any concerns." The document being referenced is a PDF file attachment, which pretends to be a notification for Office 365 file sharing.

The page tells the recipient that the sender has shared a document on behalf of the company, and again asks the target to click on a button to "Get Started." Finally, this last link redirects the victim to the actual phishing landing page, which purports to be a Microsoft Single Sign On page for Outlook, and asks the victim to input their credentials.

"When the victim submits his or her corporate Office 365 credentials as if for a normal login, the sensitive data is sent to a separate data server with an extra email address which is hidden on the page," said researchers.
