zero-day vulnerability
A zero-day vulnerability is a yet-to-be-discovered chink in the armor of safety, the whistle that signals the start of a cyberwar. The finder is instantly hailed as hero or villain overnight and forced into a fugitive life until a patch is distributed. Manufacturers want to pretend it never existed, and users live in constant dread of the next attack. Everyone prays for the patch’s arrival while endlessly playing digital tag with an invisible enemy. It is the ultimate self-denial of a system striving for perfection.
