Auto Posting with Spammy Posts

Recently I have been seeing posts that have been automatically posted to my website blog with titles and descriptions showing Louis Vuton, Air Jordans, and other random spam. I am all updated as far as plugins and wordpress core is concerned. .htaccess all clean and I am running Wordfence with no errors. I also have sitelock monitoring so I know this is more of a spam hack.

Any suggestions, not really a meta pharma hack so not sure where to look.

Anyone see this before?

BTW they are posting with my admin account even with password changes – and no my name is not admin ??
