SCENARIO:
A security analyst has been assigned a ticket from the help desk stating that users are experiencing errors when attempting to open files on a specific network share. These errors state that the file format cannot be opened. IT has verified that the file server is online and functioning, but that all files have unusual extensions attached to them.
The security analyst reviews alerts within Cortex XSIAM and identifies malicious activity related to a possible ransomware attack on the file server. This incident is then escalated to the incident response team for further investigation.
Upon reviewing the incident, the responders confirm that ransomware was successfully executed on the file server. Other details of the attack are noted below:
• An unpatched vulnerability on an externally facing web server was exploited for initial access
• The attackers successfully used Mimikatz to dump sensitive credentials that were used for privilege escalation
• PowerShell was used on a Windows server for additional discovery, as well as lateral movement to other systems
• The attackers executed SystemBC RAT on multiple systems to maintain remote access
• Ransomware payload was downloaded on the file server via an external site "file io"
QUESTION STATEMENT:
Which forensics artifact collected by Cortex XSIAM will help the responders identify what the attackers were looking for during the discovery phase of the attack?
A security analyst is reviewing alerts and incidents associated with internal vulnerability scanning performed by the security operations team.
Which built-in incident domain will be assigned to these alerts and incidents in Cortex XSIAM?
An incident in Cortex XSIAM contains the following series of alerts:
10:24:17 AM - Informational Severity - XDR Analytics BIOC - Rare process execution in organization
10:24:18 AM - Low Severity - XDR BIOC - Suspicious AMSI DLL load location
10:24:20 AM - Medium Severity - XDR Agent - WildFire Malware
11:57:04 AM - High Severity - Correlation - Suspicious admin account creation
Which alert was responsible for the creation of the incident?
For a critical incident, Cortex XSIAM suggests several playbooks which should have been executed automatically.
Why were the playbooks not executed?
In which two locations can mapping be configured for indicators? (Choose two.)
In addition to defining the Rule Name and Severity Level, which step or set of steps accurately reflects how an analyst should configure an indicator prevention rule before reviewing and saving it?
A Cortex XSIAM analyst is reading a blog that references an unfamiliar critical zero-day vulnerability. This vulnerability has been weaponized, and there is evidence that it is being exploited by threat actors targeting a customer's industry. Where can the analyst go within Cortex XSIAM to learn more about this vulnerability and any potential impacts on the customer environment?
In the Endpoint Data context menu of the Cortex XSIAM endpoints table, where will an analyst be able to determine which users accessed an endpoint via Live Terminal?
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"?
Based on the artifact details in the image below, what can an analyst infer from the hexagon-shaped object with the exclamation mark (!) at the center?
