Yesterday, 12:41 AM, the emails say, I've got one email for each worpdress account I manage locally. Between 1 and 4 emails were sent for each blog, with the following message:
Your new WordPress blog has been successfully set up at:
You can log in to the administrator account with the following information:
We hope you enjoy your new blog. Thanks!
--The WordPress Team
XXXXXX were random passwords. One different each time.
There are different hours in the source code, all of them end with 41min, so I'm not so sure of the time they were sent/generated, but I installed a Chrome extension to manage the passwords that same day.
Is there any chance it hacked my blogs?
The extension is: LastPass.
I don't think someone outside trying to access my blogs since I'm behind a router and a modem. If my webserver (Mac) is serving pages is not outside this house.
Now, what concerns to wordpress: What is what triggers those messages in a non hacked (e.g. accidentally damaged database or deleted files) blog? (Rather several blogs)
