Today let’s talk about why zero-day vulnerabilities in software are so dangerous. There are many types of vulnerabilities known to the information security community and classified by threat or severity level. The term ‘zero-day’ refers to the number of days that the developers have had to fix a new vulnerability. Thus, a zero-day vulnerability is a program security breach for which a security patch or protection tool is not yet available. Zero-day vulnerabilities are not always exploited by the hackers who found them, but sometimes this info is sold on the darknet to buyers who want to monetize it: to steal a database of user contact details, deliver phishing attacks, etc. To keep safe, one needs to update its software regularly using automatic updates. This will minimize the risk of incidents caused by zero-day vulnerabilities.
