A zero-day exploit targets a vulnerability that the software vendor doesn't know exists. There are ZERO days of protection.
How Zero-Days Are Discovered
- Bug Bounty Hunters: Report to vendor for reward
- Security Researchers: Analyze code for flaws
- Government Agencies: NSA, Unit 8200 find and sometimes stockpile
- Criminal Groups: Find and sell or use for attacks
