Office 365 Admins Can Now Block Malicious Microsoft Query IQY Files

Office 365 Admins Can Now Block Malicious Microsoft Query IQY Files. Microsoft has silently added a new Group Policy (GPO) to allow Office 365 admins to block Excel users from opening untrusted Microsoft Query files with IQY, OQY, DQY, and RQY extensions. Microsoft Query files are used to retrieve data from external sources such as corporate Microsoft Office Access, Microsoft SQL Server, and Microsoft SQL Server OLAP Services servers, Excel workbooks, and even from text files.

There have many reported malicious attacks actively using IQY files and delivering remote access trojans and malware loaders in the last 18 months. Unfortunately for most, user error is what causes most cyberattacks. It is not as simple as telling a user not to open any attachments from unknown users, as many malicious attacks imitate a known user and only the user paying strict attention could notice the slight infraction.
