Wanna disable Defender when enabled Isolated Core and Tamper protection?

Its a bit more trouble- but doable, without ruining Isolated Core/Secureboot etc.

Defenders process will run as a unkillable protected service- so new tricks needed.

Here we go:

Ok- tamper protection is easy, just make .bat - run as adm:
:again
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WdFilter\Instances\WdFilter Instance" /v altitude /t REG_SZ /d -1 /f
goto again

Then unload minifilter with process hacker:
The registry key will be changed while the minifilter do not protect it, when tamper protection makes the driver load again it cannot attach to volumes nor protect registry keys.

Removing it will make it recreate, but invalid altitude do the trick
Notice now the service is: Protected light(antimalware)
Now we cant do anything to the service/process- not even see its open handles.
Lets start by elevating to SYSTEM- just launch a command prompt, then close process hacker- and run it again from the command prompt.
Now process hacker runs as SYSTEM
Find the services process again- select the token tab.

Right click and disable the two groups:

WinDefend
Administrators

Now defender no more constant opens files- it dosnt do anything actually....

If you wanna permanently disable it its easy enough now there is no protection on its files.

If you mklink MsMpLics.dll:q nul it will not run on restart- but you loose the isolated core status :S
But secure boot and core isolation is still running fine
I am surprised that the protected services tokens are not protected.... that seems like bad design...

It also means we can impersonate them- here I impersonate SecureSystem:

The Internet and mobile phones have taken over our lives. But it comes with increasing security concerns. Website data breaches, phishing attacks, and other online scams are commonplace. Here's a thread for regular people on how to increase your security online.

#1
Go to your Google account settings. Revoke permissions from all the apps you don't use:

Also check if any app has access to your contacts or - gasp! - your entire email. Strongly reconsider both, especially access to your email.

Giving access to your contacts lets companies spam those people.

Giving access to your email - email organising apps, for instance - renders your online security meaningless. Password resets are often done with email, and if an external entity can access that, game over!

#2
Go to your Twitter account settings and revoke permissions from all the apps you don't use or trust:

Online quizzes and such sites often ask for permission to post tweets for you, read your tweets, and even your DMs!.

People click "OK" without reading the fine print.

But imagine the security and privacy risk with having some unknown entity be able to post tweets and read your private DMs just to post the results of what Game of Thrones character you are.
