The phrase Office macros is a harmless-sounding, low-tech name that refers, in real life, to program code you can squirrel away inside Office files so that the code travels along with the text of a document, or the formulas of a spreadsheet, or the slides in a presentation. Even though the code is hidden from sight in the file, it can nevertheless sneakily spring into life as soon as you use the file in any way.

Microsoft is shutting the door on a couple of routes cybercriminals have used to attack users and networks. The issue of macros has become a particularly gnarly one for the software giant.

Microsoft has officially resumed blocking Visual Basic for Applications macros by default across Office apps, weeks after temporarily announcing plans to roll back the change. Earlier this February, Microsoft publicized its plans to disable macros by default in Office applications such as Access, Excel, PowerPoint, Visio, and Word as a way to prevent threat actors from abusing the feature to deliver malware.

DOUG. A brief history of Office macros, a Log4Shell style bug, two OpenSSL crypto bugs, and more. DUCK. If you have a Windows network where you can use Group Policy, for example, then as an administrator you can turn this function on to say, "As a company, we just don't want macros off the internet. We're not going to even offer you a button that you can say, Why not? Why not let the macros run?".

A massive phishing campaign has been targeting Office 365 users in over 10,000 organizations since September 2021 and successfully bypassing multi-factor authentication set up to protect the accounts. The attackers use proxy servers and phishing websites to steal users' password and session cookie.

It's demanding a return to the freewheeling days of the last millennium, when Office macro viruses didn't face the trials and tribulations that they do today. Worst of all, perhaps, an infected document could implant macros into the global template, thus infecting the computer, and the same macros could copy themselves back out again.
