Changes to Default Behavior in Cortex XDR Agent 7.6
The following topic describes changes to default behavior
in Cortex XDR agent 7.6.
Change to Behavior
To support the Benign with Low Confidence
verdict, a new field was added to the WildFire verdict local database.
As a result, when you upgrade a Cortex XDR agent release prior to
7.6 to a Cortex XDR agent 7.5, the local WildFire cache is deleted,
which could increase the number of initial WildFire queries on the
endpoint after upgrade.
Retaining Cortex XDR extensions in macOS
To comply with the new operating system
behavior starting with macOS 11.3, where uploading a configuration
file in MDM automatically unloads from the endpoint any previously
uploaded extensions by the same vendor, the Cortex XDR agent 7.6
and later retains its extensions on the endpoint in such cases.
Aggregated pop-up for Agent Uninstall
To improve user experience, now when you uninstall
the Cortex XDR agent from endpoints running macOS 10.15.4 or later,
you are prompted only once to enter your admin password.
Reverse Shell Protection
Starting with this release, if the Cortex
XDR agent is operating in asynchronous mode then Reverse
Shell Protection is not supported. For more information on supported
kernel modules, see the Palo Alto Networks Compatibility Matrix.
Ransomware files set with different
Some ransomware decoy files will now be
set with a different set of Windows attributes that result in better coverage
for specific ransom use case.
