Post Views: 3,006 Great question. In one sentence it is a purple tool, meaning both! Wireshark itself is a passive tool, it is non-intrusive — it doesn’t create attacks — but it’s a force multiplier for both Red and Blue Teams depending on who controls the capture point and how the data is used. Let
