    Behaviour hypotheses and follow-up planInclude the evidence supporting your conclusion. Hashes and tool versions let another analyst identify the same sample and method.

    Write a static triage report for a benign training binary

    An analyst must assess an unfamiliar educational binary before deciding whether further analysis is justified. The exercise focuses on evidence and safe handling.
