Top 10 Zero-Day Attacks

Introduction:

A zero-day attack refers to the exploitation of a vulnerability in software or hardware that is not yet known to the developers, hence preventing them from addressing and patching the fault in a timely manner.  These attacks can do significant harm when they exploit systems that are commonly perceived as being secure.
