Trend Micro Apex One - New File Location for iCore Service (PPPC Considerations)

Thanks for posting this so quickly. I've updated my previously working PPPC profile for our Apex One but I still don't see iCoreService listed after the profile applies and I've added the TrendMicroSecurity.app to the profile and that appears, but isn't checked. What am I missing?

Setting it up like above I get a Failed Command in the Inventory of my test machine.

In the payload (UUID: 543F8AE3-ED19-49E8-9645-9EB3BB104268), the key 'CodeRequirement' has an invalid value.

Don't we also need to give Trend Micro.app full disk access as well?

I was only made aware of the change following an overnight update to the Apex One application and being met with the attached image:

So I believe that the PPPC setup for Apex One on all versions up to v.3.5.3617 will be fine, but when the Agent and Console are updated you will need to have the new location added to the PPPC profile

I just pushed out the new PPPC but it does not start working until Trend is restarted. Anyone have a script for that?

I must be missing something Still getting invalid value in code requirement. Can I get a copy paste of what is in one that works? Or a download of one that works? I can deal with restarting the app that's way easier than trying to get the rest done for each user.

@erichughes Here is a screenshot of the PPPC config that works for us... Hope it helps.

Just in Case...

Identifier: com.trendmicro.tmsm.MainUI Identifier Type: Bundle ID Code Requirement: identifier "com.trendmicro.tmsm.MainUI" and anchor apple generic and certificate 1[field.1.2.840.113635.100.6.2.6] / exists / and certificate leaf[field.1.2.840.113635.100.6.1.13] / exists / and certificate leaf[subject.OU] = E8P47U2H32 App or Service: SystemPolicyAllFiles Allow

and

Identifier: com.trendmicro.icore Identifier Type: Bundle ID Code Requirement: identifier "com.trendmicro.icore" and anchor apple generic and certificate 1[field.1.2.840.113635.100.6.2.6] / exists / and certificate leaf[field.1.2.840.113635.100.6.1.13] / exists / and certificate leaf[subject.OU] = E8P47U2H32 App or Service: SystemPolicyAllFiles Allow

Thank you very much. Finally got it. The star characters were messing me up. Once I got that it works once the client machine is restarted. Much appreciated.

@erichughes I am also getting the same error. when you say the star characters, what exactly do you mean?

@erichughes Sorry. I see the star characters you were talking about. I just added them and am waiting to see if it works. Thank you all.

We use WFBS Trendmicro and had to do the same thing last night for our macs as well.

Has anyone successfully gotten this to work on Big Sur? I've followed the above comments and created my own PPPC(using the utility). I'm always getting: the key 'Authorization' has an invalid value. Anyone willing to export their working config for Big Sur?

How did you proceed with Kernel Extensiond Approved?

Can anyone please share their profile and Kernel Extension? I get the same screen as SAMT above.
I used the following article: https://success.trendmicro.com/solution/000277823#

I've been struggling with Trend also. Working both with JAMF and TrendMicro on this issue. Please if anyone has a PPPC that they can share, that would be most helpful.

@jbryant Were you ever able to get this resolved in Big Sur? Did JAMF or TrendMicro have any feedback?

We found checking the FIELD_ALLOW_NON_ADMIN_USER_APPROVALS at least allows users to authorize their own kernel extensions, but we've still been unable to completely automate it.

Hello everyone,

I stumbled upon this thread while trying to get TMSM upgraded to support Big Sur for my organization. I believe I have created a configuration profile to eliminate all prompts - I found the Trend documentation incomplete so I wanted to share what I put together.

I have three privacy profile settings. Two are based off of the Trend documentation, and the last one is based off the prompt from the application to give the extension full disk access (which is not in their documentation).

Next, I have a Kernel Extension payload. I did not specify the Bundle IDs, but you probably could (in Trend's documentation).

Next is a System Extension payload. This is also not in Trend's documentation, but will suppress the "iCoreService would like to filter network content" message.

Even with this system extension, after Trend starts up, there will be an additional "iCoreService would like to filter network content" message. To suppress that, I had to create a content filter payload. Full disclosure - I am not sure if the Filter Order should be Inspector or Firewall. I went with Inspector as that is what another application we use uses (CrowdStrike).

With all these pieces together, I no longer get any Apple prompts. On Big Sur, Trend will still prompt to approve the system extension (even though it's already approved). When the user opens system preferences, they will get a message that they need to reboot (new behavior with Big Sur that reboots are required for system extensions). After a reboot everything should be fine without any additional prompts.

You are correct mnickels. I have worked with our Trend Support rep and he actually provided me with some "Official" PPPC's. Granted I had to fix one of them and added a few more to the allowed list(Don't forget to restart after install). I can provided if someone has need of them. Also I'd like to point out that if you have M1 computers in your future, they are NOT supported by TrendMicro. Even manually installing the client, it will not function as inteneded. I just learned that support for the Apple M1 chips is planned for Q2 2021.

@jbryant Can you please share the profiles with me? We keep struggling with TM on Big Sur. Any help will be much appreciated.

@jbryant I've had a look on Big Sur on an M1 and Trend installs fine and appears to run but there is no way to automate approval of the kernel extension like before. It's incredibly annoying.

From TrendMicro (aka Horse's Mouth):
Screenshot was modified to protect the innocent...

Here is a link to my PPPC's: Google Drive Link. There are 5 PPPC's in this .zip file. 4 are from TrendMicro and the 5th one, "Trend Micro - iCoreService v2" was mine that I had to create and test and test and test. I'm sure someone out there could combine these PPPC's and make this a more pleasant experience to upload and manage but this is how I was able to make it work.

Again, this is for INTEL Big Sur computers ONLY and REBOOT IS NEEDED after install. M1 is NOT SUPPORTED. I hope this helps!!

PS- If you are able to combine these PPPC's hit me up with a download link.

Hello,
I've been able to get all but browser plugin extension for -Mozilla Firefox Extension working. The download to the mobileconfig is here: https://success.trendmicro.com/solution/000277823#
when I upload the mobileconfig, nothing is shown in Custom Settings. Has anyone gotten this to work? FWIW - on the macs that I've tested, I don't even have Firefox installed.

@ jbryant

Thanks for sharing the profiles. I had to make 1 adjustment in the "TrendMicro_-_System_Extension" profile (see attached image) .

@mnickels So I created all of this, looking at your screenshots and the Trend documentation, however I continually get Failed - Under Status it says: In the payload (UUID: 06BB9690-EC13-44DB-A756-B6E68A2B4135), the key 'CodeRequirement' has an invalid value.
