WordPress Username Enumeration
This IP probed the WordPress ?author= parameter to enumerate valid usernames (e.g. ?author=1, ?author=2). Harvested usernames are then fed into credential stuffing or password brute-force attacks. This is purely reconnaissance — there is no legitimate reason to systematically probe author IDs.
