A pricing signal is a change in market price that suggests something about demand, scarcity, or buyer interest. In cybercrime markets, it can appear when stolen access, malware, or other illicit goods become more expensive because more attackers want them, or cheaper because supply is abundant or quality is poor.
This matters in security because price movement can act as low-level threat intelligence. A rising price for a certain type of enterprise access may show that defenders are making that access harder to obtain, or that criminals value it more for ongoing attacks. A falling price may suggest oversupply, lower reliability, or a shift in attacker focus. Analysts watch these signals to understand where criminal attention is concentrating and which assets are becoming more attractive targets.
