We received two emails over the holiday allegedly from WordPress with this subject line: WordPress data base upgrade required! (and marked High Priority). ARE THESE LEGIT (really from WordPress) OR are they spam/malware??
From: WordPress.org <email@example.com>
Database Upgrade Required
Your WordPress database is out-of-date, and must be upgraded before 30-Nov-2013.
The upgrade process may take a while, so please be patient.
