Which data type is the most beneficial to recreate a binary file for malware analysis

Alert data only signals that a suspicious event occurred and does not contain the raw packet payload needed to reconstruct a file.

Session data, in the context of network security monitoring, refers to full packet capture (PCAP) data that retains the entire payload of each packet exchanged between hosts. Because binary files are transmitted as raw bytes within these payloads, a complete session recording allows analysts to reassemble and extract the original binary artifact for malware analysis.

Statistical data provides aggregated metrics such as byte counts and connection frequencies, not the actual content required to rebuild a binary.

Extracted content data may already be partially processed or incomplete, whereas the raw session provides the unaltered byte stream necessary for accurate binary reconstruction.
