Microsoft to Block Office VBA Macros by Default Due to Security Concerns
Citing an increase in cyberattacks, Microsoft has announced that it will disable Visual Basic for Applications (VBA) macros in Office apps. This change will help improve the security of Office users as VBA macros as susceptible to malicious activities that can target users and access their devices.
Microsoft to Block VBA Macros in Office by Default
Microsoft, viaa blog post, announced that it willdisable VBA macros obtained from the internet by default. It means that Office users will not be able to enable certain content on Office files with a simple click of a button.
For those unaware, Microsoft Office has been supporting VBA macros, whichallows users to run custom-generated functionswith easy access, since the release of Excel 5.0 in 1993. The company rolled out the feature to its other applications with Office 97.
While the feature was pretty useful, hackers have been using VBA macros in Office documents to send malicious programs to users, who unknowingly enable them after downloading the file from the internet. Although Microsoft introduced awarning sign that shows the risk of enabling VBA macros in Office documentsobtained from the web, users could still enable them.
As a result, the “impact can be severe including malware, compromised identity, data loss, and remote access.” However, with this new policy in place, Microsoft willentirely disable VBA macros in Officeand show a new warning bar, notifying the user about the change along with a “Learn More” button. There won’t be an easy way to download the macros from now on. You can check out the preview of the new warning bar right below.
The new change will be available on five Microsoft most Office apps on Windows. These include Excel, Access, PowerPoint, Visio, and Word. Although these apps do support VBA macros on macOS as well, Microsoft says thatthis will be exclusive to the Windows platform.
The company plans to roll out the VBA macro change to its Current Channel (Preview) users with Office 365 version 2203 in early April this year. Microsoft will expand it to other update channels like Monthly Enterprise Channel and Semi-Annual Enterprise Channel later. This is also expected to reach Office LTSC, Office 2021, Office 2019, Office 2016, and Office 2013 at a later date, which is yet to be determined.
