Event log 4648 - Account used, but can't see where

Jump to solution

Hi All,
Would be great to get some help with this guys.
I get the following event IDs, using my admin account (which gets locked out). I can't see where these  credentials are used for the life of me. I've looked at server tasks and nothing there.

---------------------------------------------------------------------------------------------
---Event ID 4648
A logon was attempted using explicit credentials.

Subject:
    Security ID:        SYSTEM
    Account Name:        SYSTEM
    Account Domain:        NT AUTHORITY
    Logon ID:        0x7fbbb18
    Logon GUID:        {00000000-0000-0000-0000-000000000000}

Account Whose Credentials Were Used:
    Account Name:        ************Admin account
    Account Domain:        
    Logon GUID:        {00000000-0000-0000-0000-000000000000}

Target Server:
    Target Server Name:    ePO FQDN
    Additional Information:    ePO FQDN

Process Information:
    Process ID:        0x4
    Process Name:        

Network Information:
    Network Address:    -
    Port:            -

This event is generated when a process attempts to log on an account by explicitly specifying that account’s credentials.  This most commonly occurs in batch-type configurations such as scheduled tasks, or when using the RUNAS command.
---------------------------------------------------------------------------------------------


---------------------------------------------------------------------------------------------
---Event ID 4624
An account was successfully logged on.

Subject:
    Security ID:        SYSTEM
    Account Name:        My PC
    Account Domain:        Domain
    Logon ID:        0x3e7

Logon Type:            9

New Logon:
    Security ID:        SYSTEM
    Account Name:        SYSTEM
    Account Domain:        NT AUTHORITY
    Logon ID:        0x7fbbb18
    Logon GUID:        {00000000-0000-0000-0000-000000000000}

Process Information:
    Process ID:        0xc9c
    Process Name:        C:\Program Files\McAfee\DLP\Agent\fcags.exe

Network Information:
    Workstation Name:    
    Source Network Address:    -
    Source Port:        -

Detailed Authentication Information:
    Logon Process:        Advapi  
    Authentication Package:    Negotiate
    Transited Services:    -
    Package Name (NTLM only):    -
    Key Length:        0

This event is generated when a logon session is created. It is generated on the computer that was accessed.

The subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.

The logon type field indicates the kind of logon that occurred. The most common types are 2 (interactive) and 3 (network).

The New Logon fields indicate the account for whom the new logon was created, i.e. the account that was logged on.

The network fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.

The authentication information fields provide detailed information about this specific logon request.
    - Logon GUID is a unique identifier that can be used to correlate this event with a KDC event.
    - Transited services indicate which intermediate services have participated in this logon request.
    - Package name indicates which sub-protocol was used among the NTLM protocols.
    - Key length indicates the length of the generated session key. This will be 0 if no session key was requested.

I also have an event 4634 and 4672 - not sure they'll be of any value.

Thanks in advance.

fcags.exe is a DLP process.  I have no idea why that process would need any credentials.  You might want to post under the dlp team for that.  As for epo, there are several ways an account would be used.  If it is the account used to authenticate to the database, it also needs local logon rights (local administrative account on epo server).  If you have distributed repositories using that account for replication credentials (unc type), that can cause lockouts.  If you have server tasks that require credentials, such as an agent deployment, registered servers, etc., that also can cause lockouts.  I believe there are looks for Active Directory that can pin down the source of the use of that account to help identify it.

I've reporsted this to DLP, as I removed DLP and the events didn't appear on a Wakeup call.
Admin, please close this.
