Botnet InfrastructureChinaNet (AS4134, China Telecom)
ChinaNet (AS4134) is one of the highest-volume attack-originating ASNs globally, consistently ranking in SANS/DShield top-10 attacker lists.

SSH brute-force from this network targets common username dictionaries at scale — automated, persistent credential-harvesting botnet behavior.
Attack Analysis
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.
