After finding a suspicious executable in a protected lab, an analyst observes code structures resembling a previously identified malicious tool. Which approach is an effective way to verify that the suspicious file is related to the older sample?
Conduct a hash check on the new sample against a global repository
Use a performance monitor to track resource consumption while it executes in a lab
Analyze the file’s metadata for similar names and file properties
Compare unique code structures in the suspicious file with segments from the known malicious tool
Comparing relevant code portions reveals if they share the same foundational logic. Hash checks and system resource observation offer broad indicators, and metadata reviews might provide basic details, but detailed comparison of unique code segments or function calls confirms if both samples stem from the same malicious lineage.
