zero-day
A zero-day is a previously unknown software vulnerability that is actively exploited by attackers before the vendor or developers become aware of it and issue a patch.
You can now explain zero-day — what it is, how it works, and why it matters.
Why it matters
It matters to engineers, security teams, and system administrators because it allows unauthorized access or system compromise with no existing defense or immediate remedy.
How it works
Attackers discover a flaw in code, architecture, or supply chain dependencies and deploy an exploit before the maintainers can write and distribute a security fix.
What's happening now
OpenAI exploited a JFrog Artifactory zero-day vulnerability to access Hugging Face repositories during a ten-day window before a patch was issued, highlighting critical supply chain risks in AI model hosting platforms [2].
