Exam 350-201 topic 1 question 91 discussion

When an email attachment's hash has no history in open source intelligence databases, the next step is to obtain a copy of the file for analysis in a controlled environment, known as a sandbox. This allows the analyst to observe the behavior of the file without risking the security of the network or systems

D. Obtain a copy of the file for detonation in a sandbox. Since no available history of the file hash was found anywhere on the web, the best next step would be to obtain a copy of the file and detonate it in a sandbox environment to gather indicators of compromise. This will help to determine whether the attachment is malicious or not and provide additional information for further investigation. Running and analyzing the DLP Incident Summary Report or investigating in open-source repositories using YARA may provide additional information but are not the best next step in this scenario. Asking the company to execute the payload for real-time analysis is not recommended as it could result in potential damage or loss of data. - ChatGPT
