Abstract

Learn about using Cortex XDR agent app for Android after you have installed it.

After you install Cortex XDR for Android, scan all apps installed on the Android endpoint. For each app Cortex XDR detects, it generates a hash for the file and requests the file verdict from Cortex XDR. If necessary, Cortex XDR queries WildFire for the verdict.

After the initial scan, Cortex XDR inspects apps immediately as they are installed, and as automated or manual scans occur. At regular intervals, Cortex XDR also rechecks all verdicts with WildFire. For unknown apps, Cortex XDR agent sends the unknown file to Cortex XDR for in-depth analysis. If a verdict cannot be determined after the apk file was uploaded to Wildfire for analysis, Cortex XDR performs local analysis. The administrator can configure the behavior for both actions from Cortex XDR in the Malware Security Profile for Android.

The Cortex XDR home page displays the status of anti-malware protection, a numerical summary, and a list of the apps installed on the Android endpoint. Cortex XDR automatically refreshes the summary when it discovers new apps and receives updated or changed verdicts. You can access more information about each app from the home page.

The following categories are used to classify apps:

  • MalwareCortex XDR blocks an app if the app has a Malware verdict as determined by WildFire or local analysis, is blocked by a hash exception policy, or is unknown. To block unknown apps, the administrator must enable Cortex XDR to Block files with unknown verdict in the Malware Security Profile for Android endpoints. When Cortex XDR blocks an app due to a hash exception policy, Cortex XDR shows the app with a Block status.

  • AllowedCortex XDR allows an app to run if the app has a Benign verdict as determined by WildFire or local analysis, or is signed by a trusted signer. The administrator can add signers to the allow list as part of the Malware Security Profile for Android endpoints.

  • Pending—A pending app is an app that has not yet received an official WildFire verdict. Unknown apps are allowed to run only when this feature is enabled in the Cortex XDR policy.

Take action on malware, blocked apps, and unknown files

When you attempt to run a malicious app, a blocked app (as defined by a hash exception policy), or an unknown app, Cortex XDR automatically blocks the app from running according to your organization's policy. The administrator can configure Cortex XDR to treat grayware in the same way as it treats malware.

If Cortex XDR identifies a malicious or suspicious (unknown) app, Cortex XDR prompts you with the following actions:

  • Stop—Opens the corresponding settings page of that app, where you can stop the app.

  • Uninstall—Remove the malware from the Android device. From the home screen, go to Related AppsMalware, and then click the trash can icon for the app that you want to remove.
