Question 1

A threat hunter discovers a true negative event from a zero-day exploit that is using privilege escalation to launch "Malware pdf.exe". Which XQL query will always show the correct user context used to launch "Malware pdf.exe"?

Aconfig case_sensitive = false | dataset = xdr_data | filter event_type = ENUM.PROCESS | filter action_process_image_name = 'Malware.pdf.exe' | fields causality_actor_effective_username

Bconfig case_sensitive = false | dataset = xdr_data | filter event_type = ENUM.PROCESS | filter action_process_image_name = 'Malware.pdf.exe' | fields actor_process_username

Cconfig case_sensitive = false | datamodel dataset = xdrdata | filter xdm.source.process.name = 'Malware.pdf.exe' | fields xdm.target.user.username

Dconfig case_sensitive = false | dataset = xdr_data | filter event_type = ENUM.PROCESS | filter action_process_image_name = 'Malware.pdf.exe' | fields action_process_username

Answer : A

The correct answer is A -- the query using the field causality_actor_effective_username.

When analyzing events where privilege escalation is used, it is essential to identify the original effective user that initiated the causality chain, not merely the process's own running user (as provided by other fields). The field causality_actor_effective_username specifically provides the effective username context of the actor behind the entire chain of actions that resulted in launching the suspicious executable.

Explanation of fields from Official Document:

causality_actor_effective_username: This field indicates the original effective user who started the entire causality chain.

actor_process_username and action_process_username: These fields indicate the immediate process username, not necessarily reflecting the correct original context when privilege escalation occurs.

Therefore, to always identify the correct user context in privilege escalation scenarios, option A is the verified correct answer.

Question 2

An analyst conducting a threat hunt needs to collect multiple files from various endpoints. The analyst begins the file retrieval process by using the Action Center, but upon review of the retrieved files, notices that the list is incomplete and missing files, including kernel files.

What could be the reason for the issue?

AThe file retrieval policy applied to the endpoints may restrict access to certain system or kernel files

BThe retrieval process is limited to 500 MB in total file size

CThe endpoint agents were in offline mode during the file retrieval process, causing some files to be skipped

DThe analyst must manually retrieve kernel files by accessing the machine directly

Answer : A

The correct answer is A -- The file retrieval policy applied to the endpoints may restrict access to certain system or kernel files.

Cortex XSIAM and XDR implement security policies and permissions that may restrict the retrieval of sensitive system files, including kernel files, for safety and compliance reasons. When a file retrieval action is initiated, the endpoint policy controls which files are accessible; kernel and other protected files are often excluded from remote retrieval actions to prevent accidental or unauthorized access.

'The file retrieval policy controls which files can be remotely collected from endpoints. Sensitive files, such as kernel or system files, may be restricted by policy and are not accessible through standard remote retrieval actions.'

Question 3

Which statement applies to a low-severity alert when a playbook trigger has been configured?

AThe alert playbook will automatically run when grouped in an incident.

BThe alert playbook will run if the severity increases to medium or higher.

CThe alert playbook can be manually run by an analyst.

DOnly low-severity analytics alerts will automatically run playbooks.

Answer : A

The correct answer is A. When a playbook trigger is configured for an alert---regardless of severity---the playbook will automatically run when the alert is grouped into an incident, unless a severity condition is specifically configured in the playbook trigger. By default, the playbook will execute for any alert (including low severity) as soon as it is grouped within an incident.

''A playbook that is configured as a trigger for an alert will automatically execute when that alert is grouped as part of an incident, independent of the alert's severity unless a specific severity threshold is set.''

Question 4

A Cortex XSIAM analyst in a SOC is reviewing an incident involving a workstation showing signs of a potential breach. The incident includes an alert from Cortex XDR Analytics Alert source "Remote service command execution from an uncommon source." As part of the incident handling process, the analyst must apply response actions to contain the threat effectively.

Which initial Cortex XDR agent response action should be taken to reduce attacker mobility on the network?

AIsolate Endpoint: Prevent the endpoint from communicating with the network

BRemove Malicious File: Delete the malicious file detected

CTerminate Process: Stop the suspicious processes identified

DBlock IP Address: Prevent future connections to the IP from the workstation

Answer : A

The correct answer is A -- Isolate Endpoint.

The most effective initial response to contain a breach and reduce attacker mobility is to isolate the endpoint. This action ensures that the compromised machine can no longer communicate with the network or external systems, effectively cutting off lateral movement and exfiltration by attackers, while still allowing controlled response operations.

'Isolate Endpoint is the primary response action used to immediately contain a threat by severing all network communication, thus limiting attacker movement during active incidents.'

Question 5

How can a SOC analyst highlight alerts generated on C-level executive hosts?

AAdd the C-level executive users to the Executive Accounts asset role.

BAdd a tag to the C-level executive users

CCreate a Featured Alert field for the C-level hosts

DCreate a dynamic group for the C-level hosts.

Answer : A

The correct answer is A -- Add the C-level executive users to the Executive Accounts asset role.

By assigning C-level executives to the Executive Accounts asset role, any alerts generated from those accounts or devices are highlighted and given higher visibility in Cortex XSIAM.

''Adding C-level users to the Executive Accounts asset role ensures that related alerts are highlighted and prioritized.''

Question 6

What information is provided in the timeline view of Cortex XSIAM?

ADetailed overview of behavior or activity that triggered an Analytics Alert, Analytics BIOC alert or correlation rule

BGraphic representation of an event Causality Instance (CI) with additional capabilities to enable further analysis

CTab within an incident where analysts can collaborate and initiate further actions and automations

DSequence of events, alerts, rules and other actions involved over the lifespan of an incident

Answer : D

The correct answer is D -- Sequence of events, alerts, rules and other actions involved over the lifespan of an incident.

The timeline view in Cortex XSIAM provides a chronological sequence of all events, alerts, and actions that have occurred in relation to a specific incident, helping analysts understand the incident's progression from start to finish.

'The timeline view provides a detailed, chronological sequence of events, alerts, and actions for the lifespan of an incident.'

Question 7

Which dataset should an analyst search when looking for Palo Alto Networks NGFW logs?

Adataset = pan_dss_raw

Bdataset = ngfw

Cdataset = panwngfwtraffic_raw

Ddataset = ngfw_threat_panw_raw

Answer : C

The correct answer is C -- dataset = panwngfwtraffic_raw.

The correct dataset for Palo Alto Networks Next-Generation Firewall (NGFW) logs in Cortex XSIAM is panwngfwtraffic_raw, which contains all relevant traffic, threat, and system logs ingested from PAN NGFW devices.

''The panwngfwtraffic_raw dataset contains raw traffic logs collected from Palo Alto Networks NGFW devices and is the recommended source for investigation.''
