Logon Type 2 - Strange Activity

Question

This morning I noticed some strange activity last night on my event viewer. I checked it after seeing in my internet history that the Microsoft Edge had accessed two sites at 12.29am. See attached.

In my event log there is an event type 4624 logon type 2 at 12.29am. Is this likely someone has physically logged onto my laptop or an automated event?

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 impersonation level field indicates the extent to which a process in the logon session can impersonate.

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.

Answer 1

I have been working on this for a while now as I have about 8 pc's experiencing this as well . They are using font process , winlog on and consent.exe to log in but tracking them is difficult as I am still working on this . Has anyone had any success ?

Using SOPHOS central to find what's going on as i have some decent logs but unable to id the process or the incoming ip address . I have a few log on's using guest NT Authority and adding in new log in names as they first attack the SAM entries in the registry taking over the device / pc . Trying to find how they are maneuvering also . Just discovered about 2 months ago !
Found some strange ports on Process monitor but could not find out where on both sides ( IP Side and Internal side ) as I am working on this now !

My Windows 11 Pro even after multiple times restoring has become seriously problematic at my house !

The more I dig into this I find so many vulnerabilities !
Looks like possible log4J but there are so many other relevant viruses that I am going around in circles attempting to id this !

Does anyone here have a hardening guide ?

Looking for Microsoft to lend a hand here !

Regards

Rich

Answer 2

CVE-2020-1355]

Does anyone know if this was resolved in Windows 11 Pro ?
It looks like there are no resolutions to these vulnerabilities as the more I review the more I find and no answers to active remote vulnerabilities !
Microsoft added so many features that they increased the hackers abilities !
And we pay for them !

Good day

We have the same logins in the middle of the night.

Have you found a solution or explanation for this?
