"Delete" Notification as Office 365 Phishbait


Attackers are posing as Office 365 support in phishing emails that warn users about an “unusual volume of file deletion” on their accounts, BleepingComputer has found. The emails claim that a medium-severity alert was triggered by fifteen file deletions within five minutes. If victims click on the link to view the alert’s details, they’ll be taken to a spoofed Microsoft login page. The attackers will then collect their credentials before forwarding them to the legitimate Microsoft login portal.

A notable feature of this campaign is that the phishing pages are hosted on Microsoft’s Azure cloud services, so the URLs end with “windows.net.” As a result, even users who know that they should inspect the top-level and second-level domains of the URL could still fall for the scam. Azure-hosted sites are also secured with Microsoft SSL certificates, increasing the appearance of authenticity.

Researchers have discovered hundreds of phishing sites hosted on Azure and other cloud services in the past month. While Microsoft takes these sites down as quickly as it can, the sheer volume of malicious domains means that attackers usually have several days to carry out their attacks. Additionally, when their sites are shut down, they can easily set up more. New-school security awareness training can give your employees up-to-date knowledge of the evolving techniques and technologies being used in phishing campaigns.
