Malware triage is the fast first-pass review of suspicious files, code, or artifacts to decide how dangerous they may be and what to do next. Analysts and security tools look for indicators such as file hashes, packer signs, imports, strings, network destinations, and basic sandbox behavior. The goal is not full reverse engineering, but quick prioritization: is this likely benign, suspicious, or an active threat?
It matters because incident response depends on speed. Good triage helps separate urgent samples from noise, focus deeper analysis on the right artifacts, and trigger containment before spread. In real attacks, malware authors try to slow or mislead triage with obfuscation, packing, junk code, or text designed to confuse automated analysis. Defenders reduce that risk by treating untrusted content as adversarial, isolating analysis steps, using layered detection, and keeping human review for high-impact decisions.
