When using the "File Search and Destroy" feature, which of the following search hash type is supported?
- A. MD5 hash of the file
- B. AES256 hash of the file
- C. SHA256 hash of the file
- D. SHA1 hash of the file
Answer: C
Explanation:
Explanation
The File Search and Destroy feature is a capability of Cortex XDR that allows you to search for and delete malicious or unwanted files across your endpoints. You can use this feature to quickly respond to incidents, remediate threats, and enforce compliance policies. To use the File Search andDestroy feature, you need to specify the file name and the file hash of the file you want to search for and delete. The file hash is a unique identifier of the file that is generated by a cryptographic hash function. The file hash ensures that you are targeting the exact file you want, and not a file with a similar name or a different version. The File Search and Destroy feature supports the SHA256 hash type, which is a secure hash algorithm that produces a 256-bit (32-byte) hash value. The SHA256 hash type is widely used for file integrity verification and digital signatures. The File Search and Destroy feature does not support other hash types, such as AES256, MD5, or SHA1, which are either encryption algorithms or less secure hash algorithms. Therefore, the correct answer is A, SHA256 hash of the file1234 References:

NEW QUESTION # 34
Cortex XDR is deployed in the enterprise and you notice a cobalt strike attack via an ongoing supply chain compromise was prevented on 1 server. What steps can you take to ensure the same protection is extended to all your servers?
- A. Create lOCs of the malicious files you have found to prevent their execution.
- B. Enable DLL Protection on all servers but there might be some false positives.
- C. Conduct a thorough Endpoint Malware scan.
- D. Enable Behavioral Threat Protection (BTP) with cytool to prevent the attack from spreading.
Answer: A
Explanation:
Explanation
The best step to ensure the same protection is extended to all your servers is to create indicators of compromise (IOCs) of the malicious files you have found to prevent their execution. IOCs are pieces of information that indicate a potential threat or compromise on an endpoint, such as file hashes, IP addresses, domain names, or registry keys. You can create IOCs in Cortex XDR to block or alert on any file or network activity that matches the IOCs. By creating IOCs of the malicious files involved in the cobalt strike attack, you can prevent them from running or spreading on any of your servers.
The other options are not the best steps for the following reasons:
* A is not the best step because conducting a thorough Endpoint Malware scan may not detect or prevent the cobalt strike attack if the malicious files are obfuscated, encrypted, or hidden. Endpoint Malware scan is a feature of Cortex XDR that allows you to scan endpoints for known malware and quarantine any malicious files found. However, Endpoint Malware scan may not be effective against unknown or advanced threats that use evasion techniques to avoid detection.
* B is not the best step because enabling DLL Protection on all servers may cause some false positives and disrupt legitimate applications. DLL Protection is a feature of Cortex XDR that allows you to block or alert on any DLL loading activity that matches certain criteria, such as unsigned DLLs, DLLs loaded from network locations, or DLLs loaded by specific processes. However, DLL Protection may also block or alert on benign DLL loading activity that is part of normal system or application operations, resulting in false positives and performance issues.
* C is not the best step because enabling Behavioral Threat Protection (BTP) with cytool may not prevent the attack from spreading if the malicious files are already on the endpoints or if the attack uses other methods to evade detection. Behavioral Threat Protection is a feature of Cortex XDR that allows you to block or alert on any endpoint behavior that matches certain patterns, such as ransomware, credential theft, or lateral movement. Cytool is a command-line tool that allows you to configure and manage the Cortex XDR agent on the endpoint. However, Behavioral Threat Protection may not prevent the attack from spreading if the malicious files are already on the endpoints or if the attack uses other methods to evade detection, such as encryption, obfuscation, or proxy servers.

NEW QUESTION # 35
A Linux endpoint with a Cortex XDR Pro per Endpoint license and Enhanced Endpoint Data enabled has reported malicious activity, resulting in the creation of a file that you wish to delete. Which action could you take to delete the file?
- A. Open X2go from the Cortex XDR console and delete the file via X2go.
- B. Open an NFS connection from the Cortex XDR console and delete the file.
- C. Manually remediate the problem on the endpoint in question.
- D. Initiate Remediate Suggestions to automatically delete the file.
Answer: D
Explanation:
Explanation
The best action to delete the file on the Linux endpoint is to initiate Remediation Suggestions from the Cortex XDR console. Remediation Suggestions are a feature of Cortex XDR that provide you with recommended actions to undo the effects of malicious activity on your endpoints. You can view the remediation suggestions for each alert or incident in the Cortex XDR console, and decide whether to apply them or not. Remediation Suggestions can help you restore the endpoint to its original state, remove malicious files or processes, or fix registry or system settings. Remediation Suggestions are based on the forensic data collected by the Cortex XDR agent and the analysis performed by Cortex XDR.
The other options are incorrect for the following reasons:
* A is incorrect because manually remediating the problem on the endpoint is not a convenient or efficient way to delete the file. Manually remediating the problem would require you to access the endpoint directly, log in as root, locate the file, and delete it. This would also require you to have the necessary permissions and credentials to access the endpoint, and to know the exact path and name of the file.
Manually remediating the problem would also not provide you with any audit trail or confirmation of the deletion.
* B is incorrect because opening X2go from the Cortex XDR console is not a supported or secure way to delete the file. X2go is a third-party remote desktop software that allows you to access Linux endpoints from a graphical user interface. However, X2go is not integrated with Cortex XDR, and using it would require you to install and configure it on both the Cortex XDR console and the endpoint. Using X2go would also expose the endpoint to potential network attacks or unauthorized access, and would not provide you with any audit trail or confirmation of the deletion.
* D is incorrect because opening an NFS connection from the Cortex XDR console is not a feasible or reliable way to delete the file. NFS is a network file system protocol that allows you to access files on remote servers as if they were local. However, NFS is not integrated with Cortex XDR, and using it would require you to set up and maintain an NFS server and client on both the Cortex XDR console and the endpoint. Using NFS would also depend on the network availability and performance, and would not provide you with any audit trail or confirmation of the deletion.

- A. File Seek and Repair
- B. File Search and Destroy
- C. File Seek and Destroy
- D. File Search and Repair
Answer: B
Explanation:
Explanation
File Search and Destroy is a feature of Cortex XDR that allows you to search for and remove malicious files from endpoints. You can use this feature to find files by their hash, full path, or partial path using regex parameters. You can then select the files from the search results and destroy them by hash or by path. When you destroy a file by hash, all the file instances on the endpoint are removed. File Search and Destroy is useful for quickly responding to threats and preventing further damage. References:

What kind of malware uses encryption, data theft, denial of service, and possibly harassment to take advantage of a victim?
- A. Ransomware
- B. Worm
- C. Rootkit
- D. Keylogger
Answer: A
Explanation:
Explanation
The kind of malware that uses encryption, data theft, denial of service, and possibly harassment to take advantage of a victim is ransomware. Ransomware is a type of malware that encrypts the victim's files or blocks access to their system, and then demands a ransom for the decryption key or the restoration of access.
Ransomware can also threaten to expose or delete the victim's data if the ransom is not paid.
