At some stage in mid-late March one of the many bots that roam the web looking for vulnerable websites found mine, and exploited it to insert some sort of spamtacular crapware in every PHP file on the same account. That was nice of them, wasn’t it?
Since my blogging software was up to date, I can only assume it was my years-old customised theme. It wasn’t that great but I was attached to it. Oh well, it’s gone to live on a farm with lots of other little themes, all frolicking in the sunshine.
So it’s a fresh reinstall of WordPress and a stock theme for me. My host notified me and attempted to clean it up but really, the only way I could be sure it wouldn’t happen again was to nuke the old install and start from scratch.
