Oh shit.
Excel adds JavaScript support.

As if macro viruses weren't enough now we can worry about spreadsheets having crypto-mining malware.
This is not the future I signed up for.
@craigmaloney According to @Hairyears, VB Script has been in there for aaaaages; so, this is not a new risk.
Excel is his bread and butter, so he'd know.
@artsyhonker @Hairyears Right, I remember the first iteration of Word macro viruses flitting about on our network at Ford. They have locked things down for VBA (mostly by making it so they don't auto-run). But VBA was a bit stripped down in capabilities (last I remember playing with it) so adding a full-on JavaScript engine in there with a bunch of folks who understand JavaScript is where my pessimism begins.

VBA can make the Windows API MemCopy 'RTL' call. After that, everything is possible.
