I just logged onto my ftp and saw that a folder has been added to my WordPress folder, and it is from a corresponding 404 i got earlier today.
for the 404, the referrer was listed as libwww-perl/5.803.
My wp install is CHMOD 755.
Nothing has changed on my site.
The folder that has been put onto my server just contains more folders, no files.
What can i do to stop this happening again, and am I ok to just delete this folder straight up?
