Solution

ArtemisTest.exe Test Program
To test GTI, use the password-protected ArtemisTest.zip file in the Attachment section of this article.

NOTES:

Password protection is applied to the .zip file to make sure that it is not blocked when sent using email. Passwords normally meet higher security standards. The password is password.
The ArtemisTest.exe process is a test program and is harmless.

After you extract ArtemisTest.exe, you can run an on-access scan test and an on-demand scan test on this file.

On-access scan test
1. Make sure that your endpoint protection product (ENS or VSE) is running.
2. Open Windows Explorer and navigate to the folder that contains the test utility.
3. To start the program, double-click ArtemisTest.exe. If GTI File Reputation is enabled, ENS or VSE deletes the file or denies access and prevents the file from running. (The action taken depends on the configuration.)
4. Verify the contents of the DNS client through the command line and check whether the test file has been passed to the GTI server.
  1. To perform the on-access scan test again, double-click ArtemisTest.exe.
  2. At the command prompt, type ipconfig /displaydns and press Enter.

On-demand scan test
NOTE: To avoid an on-access scan detection, either exclude the file or directory or temporarily disable the on-access scan.

Make sure that your endpoint protection product (ENS or VSE) is running.
Open Windows Explorer and navigate to the folder that contains the test utility.

Right-click the folder or start an on-demand scan through the console for ENS or VSE. If GTI is working correctly, the On-Access Scan Messages dialog (similar to below) reports that ArtemisTest.exe has been detected. Depending on your settings, the test file is deleted and quarantined as malware.

On-Access Scan Messages
Message	VirusScan Alert!
Name:	x:\path\Artemistest.exe
Detected As:	Artemis5DB32A316F07
State:	Deleted

Solution

GTI Connectivity Test
GTI File Reputation requires that the computer can communicate with the GTI server directly using the internet or indirectly using an internal GTI proxy server. It is vital to verify that endpoints can communicate with the GTI server to make sure that the endpoint remains up to date.

Use nslookup to verify that the endpoint can connect to the GTI server.

Press Windows+R, type cmd, and click OK.
Type or paste nslookup sfqpit75pjh525siewar2dtgt5.avts.mcafee.com and press Enter.
- You see a response similar to the following if there is connectivity to the GTI server:
  
  Server: <mylocaldnsserver.org>
  Address: 161.69.135.201
  
  Name: 4z9p5tjmcbnblehp4557z1d136.avts.mcafee.com
  Address: 127.0.4.8
- Here is an example of failing connectivity to the GTI server:
  
  Server: exampleserver.your.domain.org
  Address: xxx.xx.xxx.xxx
  
  *** exampleserver.your.domain.org can't find sfqpit75pjh525siewar2dtgt5.avts.mss
  mcafee.com: Non-existent domain

Solution

PDF Lookup Test
To test GTI, use the password protected ArtemisPDF_test.pdf file in the Attachment section of this article.

NOTES:

Password protection is applied to the .zip file to make sure that it is not blocked when sent using email. Passwords normally meet higher security standards. The password is password.
The ArtemisPDF_test process is a test program and is harmless.

For GTI lookups on PDF files to happen, the following conditions must be met:

The ENS or VSE setting for GTI File Reputation must be set to Medium or higher. For instructions, see KB70130 - How to enable Global Threat Intelligence Technology in various products.
Lookups are limited to PDF files that are read or written to disk using the web browser or email client.
