Comprehensive Detailed Explanation:To safely analyze malware while avoiding unintended disclosure of company information, it is best to use a local sandbox in a microsegmented environment. Here’s why:
A. Upload the malware to the VirusTotal website
Risk: VirusTotal and similar services are public and may share uploaded files with other security vendors, potentially exposing proprietary or sensitive information.
B. Share the malware with the EDR provider
Limitation: While EDR providers may offer insight, sharing potentially sensitive malware samples externally still introduces risk of disclosure or data leaks.
C. Hire an external consultant to perform the analysis
Cost and Risk: Hiring an external consultant can be costly and may introduce risks related to third-party handling of sensitive data. Although it may provide insights, this is typically not the most efficient initial response.
D. Use a local sandbox in a microsegmented environment
Explanation: A local sandbox provides a secure, isolated environment for malware analysis without exposing sensitive data outside the organization. Microsegmentation enhances security by further isolating the sandbox from the network, preventing lateral movement if the malware attempts to communicate externally.
