Question 4

A security analyst is investigating a malware incident on an endpoint using Microsoft 365 Defender. The analyst wants to see all processes that were created on the device in the last hour, including the command line arguments. Which advanced hunting table should they query?

Accepted Answer

DeviceProcessEvents. The DeviceProcessEvents table in Microsoft 365 Defender's advanced hunting schema captures process creation events, including the command line arguments used to start each process. This directly meets the analyst's need to see all processes created in the last hour with their command-line details, making it the correct table for investigating malware that spawns processes.

Answer

DeviceNetworkEvents

Answer

DeviceFileEvents

Answer

DeviceRegistryEvents

Question 5

A security analyst is investigating a potential malware outbreak detected by Microsoft 365 Defender. The analyst needs to identify all devices that have executed a specific parent process with a given ProcessId. Which column in the DeviceProcessEvents table should be used to find processes whose parent is the specified process?

Accepted Answer

ParentProcessId. The ParentProcessId column in the DeviceProcessEvents table stores the process ID (PID) of the parent process that initiated the current process. To find all child processes spawned by a specific parent process with a known ProcessId, you query the ParentProcessId column for that value. This directly links child processes to their parent, enabling the analyst to trace the malware's execution chain.

Answer

InitiatingProcessId

Answer

ProcessId

Answer

LogonId

Question 6

A security analyst is investigating a phishing incident and needs to find the specific email message that was delivered to a user. The analyst knows the subject line and the sender domain. Which advanced hunting table should the analyst query?

Accepted Answer

EmailEvents. The EmailEvents table in Microsoft Defender XDR's advanced hunting schema contains the core properties of email messages, including subject line, sender domain, recipient details, and delivery status. Since the analyst needs to find a specific email by subject and sender domain, this table is the correct starting point for querying delivered messages.

Answer

EmailAttachmentInfo

Answer

EmailUrlInfo

Answer

EmailPostDeliveryEvents

Question 7

A security analyst is investigating a phishing campaign using Microsoft 365 Defender advanced hunting. The analyst needs to find all emails sent from a specific sender address in the last 7 days. Which table should be queried?

Accepted Answer

EmailEvents. The EmailEvents table in Microsoft 365 Defender advanced hunting stores metadata about email messages, including sender addresses, recipients, timestamps, and delivery actions. To find all emails from a specific sender in the last 7 days, you query EmailEvents because it contains the 'SenderFromAddress' or 'SenderMailFromAddress' fields needed to filter by sender. The other tables focus on attachments, URLs, or device-level events, which are not relevant for identifying emails by sender address.

Answer

EmailAttachmentInfo

Answer

EmailUrlInfo

Answer

DeviceEvents

Question 8

A security analyst is investigating a potential malware outbreak using Microsoft 365 Defender advanced hunting. The analyst wants to find all devices where a file with a specific SHA256 hash was first created and then later deleted, which may indicate a cleanup attempt. Which query pattern on the DeviceFileEvents table is appropriate?

Accepted Answer

DeviceFileEvents | where SHA256 == "<hash>" | summarize Actions = make_set(ActionType) by DeviceId | where Actions has_all ("FileCreated", "FileDeleted"). Option A is correct because it first filters by the specific SHA256 hash, then uses `make_set(ActionType)` to collect all actions per device, and finally checks that both 'FileCreated' and 'FileDeleted' appear in the set. This precisely identifies devices where the file was both created and later deleted, indicating a potential cleanup attempt.

Answer

DeviceFileEvents | where SHA256 == "<hash>" and ActionType == "FileDeleted" | project DeviceId

Answer

DeviceFileEvents | where FileHash == "<hash>" | summarize Actions = make_set(ActionType) by DeviceId | where Actions has "FileCreated"

Answer

DeviceFileEvents | summarize by DeviceId, ActionType | where ActionType in ("FileCreated", "FileDeleted")

Question 9

A security analyst is investigating a suspected lateral movement attack in Microsoft 365 Defender. The analyst wants to identify all devices where a specific user account (user@contoso.com) had an interactive logon, and then check which of those devices subsequently made outbound RDP connections to other internal IP addresses. Which KQL query approach is most efficient to find this chain?

Accepted Answer

Join DeviceLogonEvents (where AccountName == 'user@contoso.com' and LogonType == 'Interactive') with DeviceNetworkEvents (where RemotePort == 3389) on DeviceName, and filter for NetworkEvents timestamp > LogonEvents timestamp. Option A is correct because it directly correlates interactive logon events (DeviceLogonEvents with LogonType == 'Interactive') for the specific user with subsequent outbound RDP connections (DeviceNetworkEvents with RemotePort == 3389) on the same device, using a join on DeviceName and a timestamp filter to ensure the network event occurs after the logon. This approach efficiently identifies the lateral movement chain by linking the initial compromise device to the target device via RDP, leveraging the native schema of Microsoft 365 Defender.

Answer

Use IdentityLogonEvents to find the user's logons and join with DeviceNetworkEvents on IP address

Answer

Query EmailEvents to find emails sent from the user and then check DeviceNetworkEvents on the sender device

Answer

Union DeviceLogonEvents and DeviceNetworkEvents, then summarize by DeviceName and filter for the user

Question 10

A security analyst is investigating a suspicious process on an endpoint and wants to see all changes made to the Windows Registry by that process. Which advanced hunting table should the analyst query to find registry modification events associated with the process?

Accepted Answer

DeviceRegistryEvents. DeviceRegistryEvents is the correct table because it specifically captures Windows Registry modification events, including create, modify, and delete operations. For a process-based investigation, this table includes the InitiatingProcessId and InitiatingProcessFileName columns, allowing the analyst to filter by the suspicious process's PID or name to see all registry changes it made.

Answer

DeviceProcessEvents

Answer

DeviceEvents

Answer

DeviceFileEvents

Question 11

A security analyst is investigating an advanced persistent threat campaign that involves lateral movement using RDP. The analyst suspects that an attacker uses RDP from DeviceA to DeviceB, and then within a few minutes executes a malicious PowerShell script on DeviceB. The analyst wants to create a custom detection rule in Microsoft 365 Defender that triggers when this pattern occurs. Which KQL query pattern should be used to correlate these events across devices?

Accepted Answer

Use a self-join: query DeviceProcessEvents for mstsc.exe, extract the target device (e.g., from command line), and then join with another query on DeviceProcessEvents for PowerShell on the target device where the time difference between the events is less than 10 minutes.. Option A is correct because it uses a self-join on DeviceProcessEvents to first detect the mstsc.exe process (RDP client) on DeviceA, extract the target device name from the command line, and then join with a second query on DeviceProcessEvents for PowerShell on DeviceB. The join condition includes a time difference of less than 10 minutes, which directly correlates the lateral movement (RDP) with the subsequent malicious script execution across devices, matching the described attack pattern.

Answer

Query DeviceNetworkEvents for RDP connections (port 3389) and then join with DeviceProcessEvents for PowerShell on the same device.

Answer

Use the 'union' operator to combine all mstsc.exe and PowerShell events, then summarize by device and time.

Answer

Query DeviceLogonEvents for RDP logon type and then join with DeviceProcessEvents for PowerShell on the same device.

Question 12

A security analyst is investigating a sophisticated attack chain that started with a user clicking a link in a phishing email, which led to a drive-by download from a malicious website. The analyst wants to see the full list of URLs visited from the user's browser on the device. Which Advanced Hunting table contains this information?

Accepted Answer

DeviceEvents. DeviceEvents in Microsoft Defender XDR captures browser-based activities, including URL visits, via the 'ActionType' field (e.g., 'BrowserUrlClicked' or 'BrowserUrlNavigation'). This table is specifically designed to log web navigation events from browsers like Microsoft Edge or Chrome, making it the correct source for the full list of URLs visited during the phishing attack chain.

Answer

DeviceNetworkEvents

Answer

DeviceProcessEvents

Answer

DeviceFileEvents

Question 13

A security analyst is investigating an incident in Microsoft 365 Defender that involves a user who clicked a phishing link. The analyst wants to find all processes executed on the user's device immediately after the email was opened. Which advanced hunting table should the analyst query to obtain process creation events with timestamps relative to the email event?

Accepted Answer

DeviceProcessEvents. DeviceProcessEvents is the correct table because it stores process creation events (including image name, command line, and timestamp) for all devices onboarded to Microsoft Defender for Endpoint. By querying this table with a time range starting immediately after the email event (identified from EmailEvents), the analyst can correlate the phishing click with subsequent process executions on the user's device.

Answer

EmailEvents

Answer

DeviceNetworkEvents

Answer

IdentityLogonEvents

Question 14

A security analyst is reviewing an incident in Microsoft 365 Defender where malware was detected on multiple endpoints. The analyst wants to see a visual representation of the attack progression, including the initial entry point and all affected devices.
