Exploitable LDAP server used for an attack: Microsoft Active Directory / Exchange Server

You've just received notice that your Active Directory server is being used as part of a wide scale dDoS attack. Here is how you can fix it.

Go to the firewall settings on the active directory server or reported server IP and look for the following rules.

  • Active Directory Domain Controller - LDAP (TCP-In)
  • Active Directory Domain Controller - LDAP (UDP-In)
  • Active Directory Domain Controller - LDAP for Global Catalog (TCP-In)
  • Active Directory Domain Controller - Secure LDAP (TCP-In)
  • Active Directory Domain Controller - Secure LDAP for Global Catalog (TCP-In)

For each of these alter the rule by choosing the Scope tab and entering only IP addresses that should have access to LDAP information. For example, Microsoft Exchange Servers within your network that need access to LDAP.

For assistance securing your network or if you are looking for hosted exchange services check out Area51.mn.

 

The volume (DRIVE:) was not optimized because an error was encountered: Neither Slab Consolidation nor Slab Analysis will run if slabs are less than 8 MB. (0x8900002D)

This error appears in the event viewer when the scheduled task "ScheduledDefrag" runs.

Cause: In most cases this is cause by the -k switch which tells the defrager to perform a slab consolidation on the selected volume. This will cause an error for slabs that are less than 8 MB, and will commonly toss an error on HyperV VM's.

Solution: remove the -k switch from the task.

  • Open scheduled tasks, Microsoft, windows, defrag: "ScheduledDefrag"
  • Now click properties, actions, edit [start a program]
  • under add arguments(optional): remove the -k and click "ok", "ok"

That's it, your done.
