Morphology
zero-day + exploit
The term pairs a technical time-based modifier 'zero-day' (i.e., occurring at day zero, before a fix) with 'exploit' (attack/code that abuses a vulnerability), so a learner who understands those elements could roughly infer an attack targeting a newly discovered or unpatched flaw. However, 'zero-day' is jargon and the precise security sense and implications are specialized and unlikely to be fully predictable for an average B1 learner, making the expression only partially transparent.
Etymology
The term zero-day exploit comes from the image of zero-day, meaning there are 'zero days' to prepare, and exploit, meaning someone uses a new bug. So it refers to an attack that happens before the software maker has time to 'fix' the problem.
