   A threat intelligence analyst is researching a newly discovered ransomware family that appears to target organizations in the healthcare sector. The analyst needs detailed technical analysis, including indicators of compromise (IOCs), MITRE ATT&CK techniques, and recommended mitigations, to share with the incident response team. Which Unit 42 resource is most appropriate for this need?

   • AA Unit 42 threat brief or research report on the ransomware family.
   • BA VirusTotal community comment on the ransomware sample.
   • CA firewall log showing the ransomware's command-and-control traffic.

   A security engineer is explaining to a colleague how WildFire determines if a file is malicious. The engineer needs to accurately describe the core analysis method used by WildFire. Which statement is the most accurate description?

   • AWildFire executes the file in a virtualized sandbox and observes its runtime behavior, such as file system changes, registry modifications, and network connections.
   • BWildFire aggregates results from multiple third-party antivirus engines to determine a verdict.
   • CWildFire compares the file's hash against a database of known malware signatures.
   • DWildFire relies solely on static analysis of the file's code without executing it.

   A threat hunter is investigating a potentially compromised endpoint. The hunter finds a unique executable on the system and checks its hash on VirusTotal. The file is detected by only 2 out of 60 antivirus engines, and one of the detections labels it as 'Win32.Packed.Themida'. The hunter knows the file is a custom in-house tool used by the development team. What is the most likely explanation for the VirusTotal results?

   • AThe file is benign because most engines did not detect it.
   • BThe file is definitively malware because it was detected by multiple engines.
   • CThe file is a false positive, likely due to the packer used by the in-house tool.
   • DThe file is grayware because it is packed.
