Types of Cyber Attacks There are several effective methods for disrupting computer systems. We are talking of a method known as cyber attack, or computer network attack , which uses malicious computer code to disrupt computer processing, or steal data.  A brief description of three different methods are shown here. However, as technology changes, future distinctions between these methods may begin to blur. An attack against computers may be targeted or un-targeted (i) disrupt equipment and hardware reliability, (ii) change processing logic, or (iii) steal or corrupt data. The methods discussed here are chosen based on the technology asset against which each attack mode is directed, and the effects each method can produce. The assets affected or effects produced can sometimes overlap for different attack methods.  Conventional kinetic weapons can be directed against computer equipment, a computer facility, or transmission lines to create a physical attack that disrupts

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 sell infor
