Which TWO of the following initial actions should a technician take to resolve this security issue?

  1. Uninstall the unverified application from the device settings.Answer
  2. Revoke any device administrator privileges or untrusted certificates granted to the application.Answer
  3. C
    Contact the mobile carrier to submit a support ticket for local cell tower connectivity outages.
  4. D
    Reconfigure the corporate wireless network authentication protocol to use TKIP encryption.
  5. E
    Immediately perform a full factory reset on the device without isolating the application first.

Answer

Uninstall the unverified application from the device settings and revoke any device administrator privileges or untrusted certificates granted to the application.
Uninstalling the unverified application directly removes the malicious code causing high resource consumption and ad redirects. Revoking device administrator privileges or untrusted certificates removes any elevated access rights the application used to bypass mobile OS security restrictions.

Step-by-Step Solution

1
Identify and remove the unverified sideloaded application.
Stops the unauthorized background processes and stops pop-up ad redirects.
Applications obtained outside official app storefronts often contain adware or malicious code.
2
Inspect device administration settings and profile configurations to revoke elevated privileges.
Ensures the application cannot retain administrative access or bypass standard mobile OS sandbox controls.
Malicious software frequently attempts to install management profiles or claim admin rights to prevent easy uninstallation.
