I can't say whether it was or wasn't. I just know something is fishy. This is totally separate from the phishing emails. The email today said the file was changed today by this Leandro Nogueira person and sure enough, when I went to onedrive on the web, there was a valid file there by that name showing it had been altered this morning with his name by it. It was not a shared file and was useless to anyone but me. So the only way it could have been altered was for someone signed in as me to alter it. But if that be the case, why was this Leandro Nogueira person's name listed being the one who altered it. It makes no sense to me how this could have happened.I 've reported it to Onedrive support to see if there's an explanation.
Gary, you know I'm not a big onedrive user. I use the vault for a few important files and I have a list of passwords in there. I've dropped a few files into onedrive documents to use on the go. 3 or 4 times I've shared a file here on this forum. Other than that there's so little in my onedrive so I'm not too concerned about the files and I'm pretty confident the vault wasn't breached. I didn't get 2FA on my phone. What concerns me is the possibility that someone has access to my MS account. That email account is my user name for just about every other account I have. Every one of my finances and health related accounts. Of course now I've changed the password and am in the process of changing a bunch of other passwords for important accounts that have that email tied to them.
Oh well, I'll probably never know the how and why of it.
As you know, I'm a heavy OneDrive user and have been for many years. I keep all my data in my Local OneDrive folder and I have "Files On Demand" turned OFF. This gives me a 24/7 real-time mirror backup of all my data, including all my photos, in cloud OneDrive. Never, in all the years I've used OneDrive, have I ever had any evidence of anything like you're relating.
I have to ask this, when you went to OneDrive to check for the file that was changed by Leandro Nogueira, did you do so by your own OneDrive link or by a link in the email you received? Did you check that same OneDrive file using your System Two computer?
OneDrive requires an active Microsoft Account. In order to get to your cloud OneDrive, you must log in to an active Microsoft Account. If, in fact, someone has access to your OneDrive files, they have access to your Microsoft Account. You said that you immediately changed your Microsoft Account password. That should stop anyone that had the old MS Account password.
Unless someone has gained access to your computer itself without your knowledge!
If this were my situation, I would do a clean install of both of my computers. There is no other way to be certain that you are using a clean system, not even with a Macrium Restore.
