#Zero-day threats, often referred to as “zero-day vulnerabilities” or “zero-day #exploits,” are a category of #cybersecurity risks that arise from software vulnerabilities that are unknown to the software vendor or the general public. These vulnerabilities are called “zero-day” because, from the moment they are discovered or exploited by cybercriminals, there are zero days of protection for the affected software or systems. #kaspersky #tomorrowunlocked #hackernews #hacker | Kaspersky
