Zero-day malware is any malware that exploits a vulnerability not previously known to the public or to the vendor of the technology containing the vulnerability, and is, as such, often extremely potent.

Regularly creating zero-day malware requires significant resource and development. It’s quite expensive and is often crafted by the cyber armies of nation states rather than by other hackers.

Commercial purveyors of zero day malware have been known to charge over $1 million for a single exploit.
