Which of the following paths will successfully activate Remediation Suggestions?
Remediation Suggestions is a feature of Cortex XDR that provides you with recommended actions to remediate the root cause and impact of an incident. Remediation Suggestions are based on the analysis of the causality chain, the behavior of the malicious files or processes, and the best practices for incident response. Remediation Suggestions can help you to quickly and effectively contain and resolve an incident, as well as prevent future recurrence.
To activate Remediation Suggestions, you need to follow these steps:
In the Cortex XDR management console, go toIncidentsand select an incident that you want to remediate.
ClickCausality Viewto see the graphical representation of the causality chain of the incident.
ClickActionsand selectRemediation Suggestions. This will open a new window that shows the suggested actions for each node in the causality chain.
Review the suggested actions and select the ones that you want to apply. You can also edit or delete the suggested actions, or add your own custom actions.
ClickApplyto execute the selected actions on the affected endpoints. You can also schedule the actions to run at a later time or date.
What is the Wildfire analysis file size limit for Windows PE files?
The Wildfire analysis file size limit for Windows PE files is 100MB. Windows PE files are executable files that run on the Windows operating system, such as .exe, .dll, .sys, or .scr files. Wildfire is a cloud-based service that analyzes files and URLs for malicious behavior and generates signatures and protections for them. Wildfire can analyze various file types, such as PE, APK, PDF, MS Office, and others, but each file type has a different file size limit. The file size limit determines the maximum size of the file that can be uploaded or forwarded to Wildfire for analysis. If the file size exceeds the limit, Wildfire will not analyze the file and will return an error message.
Under which conditions is Local Analysis evoked to evaluate a file before the file is allowed to run?
Local Analysis is a feature of Cortex XDR that allows the agent to evaluate files locally on the endpoint, without sending them to WildFire for analysis. Local Analysis is evoked when the following conditions are met:
The endpoint isdisconnectedfrom the internet or the Cortex XDR management console, and therefore cannot communicate with WildFire.
The verdict from WildFire is of a typeunknown, meaning that WildFire has not yet analyzed the file or has not reached a conclusive verdict.
Local Analysis uses machine learning models to assess the behavior and characteristics of the file and assign it a verdict of either benign, malware, or grayware. If the verdict is malware or grayware, the agent will block the file from running and report it to the Cortex XDR management console. If the verdict is benign, the agent will allow the file to run and report it to the Cortex XDR management console.Reference:

What is an example of an attack vector for ransomware?
An example of an attack vector for ransomware is phishing emails containing malicious attachments. Phishing is a technique that involves sending fraudulent emails that appear to come from a legitimate source, such as a bank, a company, or a government agency. The emails typically contain a malicious attachment, such as a PDF document, a ZIP archive, or a Microsoft Office document, that contains ransomware or a ransomware downloader. When the recipient opens or downloads the attachment, the ransomware is executed and encrypts the files or data on the victim's system. The attacker then demands a ransom for the decryption key, usually in cryptocurrency.
Phishing emails are one of the most common and effective ways of delivering ransomware, as they can bypass security measures such as firewalls, antivirus software, or URL filtering. Phishing emails can also exploit the human factor, as they can trick the recipient into opening the attachment by using social engineering techniques, such as impersonating a trusted sender, creating a sense of urgency, or appealing to curiosity or greed. Phishing emails can also target specific individuals or organizations, such as executives, employees, or customers, in a technique called spear phishing, which increases the chances of success.

How can you pivot within a row to Causality view and Timeline views for further investigate?
To pivot within a row to Causality view and Timeline views for further investigation, you can use the Open Card and Open Timeline actions respectively. The Open Card action will open a new tab with the Causality view of the selected row, showing the causal chain of events that led to the alert. The Open Timeline action will open a new tab with the Timeline view of the selected row, showing the chronological sequence of events that occurred on the affected endpoint. These actions allow you to drill down into the details of each alert and understand the root cause and impact of the incident.Reference:
