Mystery Folders found on our server
Posted on 2008-10-03
We have noticed the sudden mysterious appearance of a folder (and over 200 subfolders) on our server in the root folder of one of our websites.
Our server is running Microsoft Server Standard 2008 and SQL Server 2005.
The name of the folder is "ÿta12311-ÿ" and inside is a series olf subfolders named "1", "2", "3", "4" and inside those... more folders also named "1", "2", "3", "4".
There are a total of 271 folders, all of them empty.
We did not create these folders, and assume the are part of a hack attempt.
Can anyone tell us
A) How they would have accessed our server
B) What they were attempting to do
C) What we should do abou this attempt
D) What we should do now to prevent further attacks like this
