[pmwiki-users] Attack ?

[Drechsel Wolf]

Hi everybody,

I'd been a happy pmwiki admin for years now. But now: It looks as if  
my wiki is being attacked:

With high cpu load on the server, the PmWikiDe.PmWikiDe file has grown  
to 106 MB, the contents is garbage of spam urls. I installed the most  
recent pmwiki 2.2.45 a few days ago, but the same happened again.

The file can be viewed at:

http://verkehrsplanung.com/PmWikiDe.PmWikiDe

I put all permissions to 777 to make the wiki work - that wasnt a good  
idea, err?
Any help would be appreciated.

Yours,
Wolf
