WHAT IS THE ZERO-DAY VULNERABILITY ?
WHAT IS THE ZERO-DAY VULNERABILITY ? A zero-day vulnerability is a previously unknown flaw in a computer program that exposes the program to external manipulation. Zero-day vulnerabilities have been found in many OS & programs, including Chrome, Internet Explorer, Adobe, and Apple products. Zero-day vulnerabilities also appear in software running critical infrastructure, such as power plants. What differentiates a zero-day from other computer vulnerabilities, and what makes it valuable, is that it is unknown to the software’s makers and users. Whoever has knowledge of a zero-day can exploit it from the “zero-th” day of its discovery, until the software maker or users learn of it and fix the vulnerability. What makes a zero-day vulnerability different from other cyber tools is that it is simply information. A zero-day encapsulates the knowledge that X could happen if you do Y. As Auriemma and Ferrante of ReVuln, a zero-day seller, argue, “we don’t sell weapons, we s...
