Do I have a risk of someone accessing my Mac environment through W7/Virtualbox?
Have to ask yourself first, how they would get into the Win7 virtual machine.
Generally you’re not going to “break out” of a virtual environment into the host OS. But all of them have had exactly that reported a handful of times.
What you’re really concerned with is the same problems as if there was a Win7 machine on your desk and a Mac right next to it, just for basics. If the real Win7 machine had malware on it, would that malware attempt to attack a Mac on the same network?
Not typically. Most malware sticks to a single OS. But certainly not unheard of on “smarter” malware. A few ransomeware examples that are smart enough to attack anything they find on the local LAN have been documented in the wild.
As an aside, I believe that serial driver issue is caused by your manufacturer using fake Prolific chips from China and Prolific fought back with their new drivers. Same thing happened to FTDI chips.
That’s digging back a few years so I may have remembered the Prolific story wrong, but it’s documented why the newer driver fails on the internet and I believe how to stop Win10 from messing with it.
Yeah. Quick google reminded me. Tons of the PL2303 chips are counterfeit.
If it’s built into your device you should ask the manufacturer what they’re going to do to fix it.
If it’s just a serial to USB cable, throw it away and use one with a non-counterfeit chipset (either Prolific or FTDI is fine). It’s so bad, most Amazon and eBay sellers even say that they’re using non-counterfeit ones in their listings.
That counterfeit chipset thing goes all the way back to the early days of Windows 8, which is when one of my cheap cables got hit by it. The googling reminded me when it said Win8 also did it.
And I recently bought a serial converter specifically for multi-voltage serial stuff like programming chips that need 3.3VDC serial and remember making sure it had a non-counterfeit Prolific on the board. Cost was $5 more for the real deal boards vs the ones with the fakes.
Yay China.
