Microsoft to block VBA macros on all Office apps

Microsoft has announced that it will now start blocking macros by default, prompting the user with a new banner that will explain them the risks of running macros from an untrusted source. The company has also added a Learn More button that links to an article explaining the security risks.

Visual Basic for Applications (VBA) macros are powerful automation tools for Microsoft Office, that are designed to make routine entry work simpler.

The problem is that these have long been abused by hackers and bad actors to deliver malicious payloads such as ransomware to unsuspecting users.
