passive threat
Technical term in security and risk analysis for a threat that does not actively attack but exploits existing weaknesses or waits for an opportunity.
Passive threats include eavesdropping and traffic analysis.
能動的脅威 (active threat) directly attacks or manipulates systems, while 受動的脅威 is passive and often involves monitoring or information gathering without altering data.
Compound of 受動的 (passive) + 脅威 (threat). A modern technical term likely calqued from English 'passive threat'.
