Hello

My ftp server was hacked and i cannot delete empty folders created by the hackers.

Here is the folder stucture, directories are emprty.

ftproot > (C1C3~1, find using dir /x) > (0303~1, find using dir /x)  > (0200~1, find using dir /x) > com9 > HeHeHe  > con > ScanneD > con > by > lpt3 > JDX > lpt1 > TaGGeD  > com3 > by > com7 > GloomyFigure > aux > (not named) >  with Neo1907´s PuB-tAgGeR > com9 > uPPed > com8 > BY > com7 > GloomyFigure > con

I've tried to find solution with the previous posts but anyone is working for me.

I cannot explore over "C:\Program Files\Ensim\Sitedata\indywood\InetPub\ftproot\C1C3~1\0303~1\0200~1":

**********************
C:\Program Files\Ensim\Sitedata\indywood\InetPub\ftproot\C1C3~1\0303~1\0200~1>cd
 com9
The system cannot find the path specified.

Also i tried to delete them using RD and RM commands but anyone was working.

A few suggestions:

Perhaps you:

A. Are typing the wrong command
B. do not have permission to view/modify files
C. the data could be streamed covertly.

Forgive me if it's a little simple, but I don't know yr skill level. Make sure you read all the way through it before trying any of this. You may not have to go this drastic and it may spark an idea.

1. Ensure you have Administrator access and that there are no additional users with this access (they may have further exploited the machine and created user accounts).

2. Ensure you can see all files through explorer (including hidden and system)

3. Disconnect from the internet, reboot into safe mode and ensure the FTP service is stopped.

4. Copy any data you require from the FTP root sideways into a backup directory (anywhere but within you FTP Root directory! :)

5. Try to delete through DOS. - RM and RD won't work as far as I know as they are Unix commands. Try "DELTREE foldere_name"

WARNING:This will delete all files and folders so BE CAREFUL!!!!

6. Install a firewall and if you must use FTP, ensure both it and windows have been locked down and patched.

7. If all else fails, delete the whole FTP root directory and restore from backup in Step 4

Hope this helps.











5. Open up DOS, get into your FTP root directory ( c:\Program Files\Ensim\Sitedata\indywood\InetPub\ftproot )
6. Type: DELTREE folder_name
7. Hit <Enter>

how are you accessing the remote system??
and what are the different ways you have available to acces the system.

also you say you have admin rights on the machine,  can you start and stop services?

in that case,  

I bet there are special characters that are valid for unix/mac but not windows that is making the delete fail.  I have a mixed environment and sometimes have to deal with renaming files on the server  from one machine (unix/mac) so I can use them on another (pc)...  darn trailing periods...  anyway..  

you'll need to kick off all other ftp connections. (to hopefully get rid of files in use..) you might want to temporarily disable logins for all users  but yours.
or disable anonymous..  I don't know how your configured. or limit connections..  you get the drift.

I would use your ftpclinet dujour  and log in with privilege to the ftp server.
change the permissions so you can have full control over the files and folders that you wan to delete
and blow them away with the ftp client.

give it a try , and let us know how it goes.

Hi,

try using filezilla.
I just tried this with my own ftp server and when I deleted a directory with something in it,
filezilla was happy to decend into the dirs and blow away files.

you can get it here.

http://optusnet.dl.sourceforge.net/sourceforge/filezilla/FileZilla_2_2_8b_setup.exe

I just want to rule out file system damage...  (ie. the os thinks there are files there, but not really.. )

I've tried with Filezinna, same things happening:

Status:      Retrieving directory listing...
Command:      CWD /InetPub/
Response:      250 CWD command successful.
Command:      PWD
Response:      257 "/InetPub" is current directory.
Status:      Directory listing successful
Command:      RMD /InetPub/2300
Response:      550 /InetPub/2300: The directory is not empty.

Thank You

in filezilla while you are connected,
click on view, and then click on "show hidden files"

and see if there is anything there...

I'm running out of ideas...
