Well, I'm also an attorney, and a very heavy user of Word. DO NOT allow the macro to run unless you are 100% sure that the file is from a trusted source and that it is supposed to have a macro in it. Now, when you receive a file that has a macro in it, you will get a notice to that effect when you go to open the file. Word menu -> Preferences -> Security & Privacy -> select: Disable all macros with notification To make sure that it is turned on, go to:

But.it doesn't work unless it is turned on AND the warnings it sends out are heeded. It's because Word has what is known as 'Macro Virus Protection' built-in. Why aren't they wildly common anymore? It's not because they have been stamped out. What you described sounds typical of the type of havoc that a Word macro virus used to cause. Because most versions of Word include Visual Basic for macros, 'Word macro viruses' used to be wildly common. It may not technically be a virus, because it does not self-replicate, and it may be incredibly uncommon, but malware for the Macintosh does exist. There is definitely malware for the Macintosh.

At minimum, it is a misleading statement. Assuming that one is using 'virus' to mean 'malware', which is how most of the world defines it, then that is patently false and I wish that folks who should know better would stop saying that. You've been told that there are 'no viruses for the Mac' in this thread. The overwhelming majority of attorneys use Word just about all day, every day.

This can be done via the File Block settings in the MS Office Trust Center settings. Outflank suggests the best way to mitigate abuse is to completely block SYLK files in MS Office. SYLK is not marked as dangerous in Chrome’s safe browsing file type list.” SYLK is not included in the default OWA blocked extensions list. Researchers note that attackers like to leverage SYLK files because it’s not just Office for Mac that can b vulnerable: “SYLK is not included in the MS Outlook blocked attachments list. “As it turns out, this file format is a very good candidate for creating weaponized documents that can be used by attackers to establish an initial foothold,” wrote researchers at Outflank in a report that posted Thursday. Using the two together, bad actors can put XLM macros into SYLK files. SYLK, on the other hand, is an ancient file format dating back to the 1980s that is still supported by Microsoft Office.

“By convincing a user to open specially-crafted Microsoft Excel content on a Mac that has ‘disable all macros without notification’ enabled, a remote, unauthenticated attacker may be able to execute arbitrary code with privileges of the user running Excel,” researchers wrote.Ī file with the XLM file extension is an Excel 4.0 Macro file. Macros allow automation so that repetitive tasks can be “played” to save time and lower the likelihood of errors. It is also been confirmed on Microsoft Office 2011 for Mac. This bug has been confirmed in fully patched Office 2016 and Office 2019 for Mac systems. “If Office for the Mac has been configured to use the ‘disable all macros without notification’ feature, XLM macros in SYLK files are executed without prompting the user,” they said. Ironically, only when a user plays it safe and configures their Office for Mac 2016 through 2019 to “disable all macros without notification” does the flaw exist. SYLK files aren’t subject to this, which leaves users “a single click away from arbitrary code-execution via a document that originated from the internet,” CERT wrote. Protected View (see image below) is a read-only mode where editing functions are disabled, which also renders malicious macros dead in the water. “Macros in the SYLK format are problematic in that Microsoft Office does not open in Protected View to help protect users.” “XLM macros can be incorporated into SYLK files,” wrote CERT on Friday. The warning comes from United States Computer Emergency Readiness Team (US-CERT), which said that symbolic link (SYLK) files can contain dangerous Excel macros. This leaves systems vulnerable to a remote, unauthenticated attackers who can execute arbitrary code. Microsoft Office for Mac users are being warned that malicious SYLK files are sneaking past endpoint defenses even when the “disable all macros without notification” is turned on.
