What is Zero Day Attack?

1741 reads · Last updated: December 5, 2024

A zero-day attack (also referred to as Day Zero) is an attack that exploits a potentially serious software security weakness that the vendor or developer may be unaware of. The software developer must rush to resolve the weakness as soon as it is discovered in order to limit the threat to software users. The solution is called a software patch. Zero-day attacks can also be used to attack the internet of things (IoT).A zero-day attack gets its name from the number of days the software developer has known about the problem.

Definition

A Zero-Day Attack, also known as Day Zero, is an attack that exploits a potentially serious software security vulnerability that the software vendor or developer may not be aware of. Software developers must address this vulnerability as quickly as possible to limit the threat to software users. The solution is called a software patch. Zero-Day Attacks can also be used to target the Internet of Things (IoT). The name 'Zero-Day' comes from the number of days the software developers have known about the problem.

Origin

The concept of Zero-Day Attacks originated in the field of computer security and has evolved with the proliferation of the internet and software. The earliest Zero-Day Attacks can be traced back to the 1990s when hackers began exploiting undisclosed vulnerabilities. As technology advanced and networks became more complex, Zero-Day Attacks became more common and sophisticated.

Categories and Features

Zero-Day Attacks can be categorized into several types, primarily targeting operating systems, applications, and IoT devices. Their characteristic is that attackers exploit the vulnerability before it is publicly disclosed, making defense extremely difficult. The advantage of Zero-Day Attacks lies in their stealth and efficiency, but the downside is that they require a high level of technical skill and resources.

Case Studies

A famous case of a Zero-Day Attack is the Stuxnet worm in 2010, which exploited multiple zero-day vulnerabilities to attack Iran's nuclear facilities. Another case is the 2017 WannaCry ransomware attack, which exploited a zero-day vulnerability in the Windows operating system, causing widespread disruption to computer systems globally.

Common Issues

Investors dealing with Zero-Day Attacks may face issues such as how to promptly detect and patch vulnerabilities and how to protect IoT devices. A common misconception is that installing antivirus software can fully defend against Zero-Day Attacks; in reality, a more comprehensive security strategy is required.

Chi-Square Statistic

A chi-square (χ2) statistic is a test that measures how a model compares to actual observed data. The data used in calculating a chi-square statistic must be random, raw, mutually exclusive, drawn from independent variables, and drawn from a large enough sample. For example, the results of tossing a fair coin meet these criteria.Chi-square tests are often used to test hypotheses. The chi-square statistic compares the size of any discrepancies between the expected results and the actual results, given the size of the sample and the number of variables in the relationship.For these tests, degrees of freedom are used to determine if a certain null hypothesis can be rejected based on the total number of variables and samples within the experiment. As with any statistic, the larger the sample size, the more reliable the results.

A rival good is a product or service that can only be consumed by one user or a limited number of users. The rivalry is among consumers, whose competition to obtain the good can create demand and drive up its price. A non-rival good, on the other hand, can be used simultaneously by many consumers.Most common household products and supermarket foods are rival goods. A bar of soap or a bottle of beer can only be consumed by a single person. If the product is in short supply, the rivalry among consumers is intensified. A limited-edition designer t-shirt is a rival good that may increase in price simply because demand outweighs supply.A non-rival good may be consumed by many people at the same time without any pressure on its supply. Streaming videos are an example.

Vendor Financing

Vendor financing is a financial term that describes the lending of money by a vendor to a customer who uses that capital to purchase that specific vendor's product or service offerings.Sometimes called "trade credit," vendor financing usually takes the form of deferred loans from the vendor. It may also include a transfer of stock shares from the borrowing company to the vendor. Such loans typically carry higher interest rates than those associated with traditional bank loans.

A vendor note is a short-term loan a vendor makes to a customer that is secured by goods the customer buys from the vendor. A vendor note is classified as a form of "vendor finance" or "vendor financing," which is a type of lending that usually takes the form of a deferred loan made by a vendor. Vendor notes are most likely to be employed when a vendor has more confidence in a customer's business prospects than a traditional lender (a bank) would.

Supply Chain Finance

Supply chain finance (SCF) is a term describing a set of technology-based solutions that aim to lower financing costs and improve business efficiency for buyers and sellers linked in a sales transaction. SCF methodologies work by automating transactions and tracking invoice approval and settlement processes, from initiation to completion. Under this paradigm, buyers agree to approve their suppliers' invoices for financing by a bank or other outside financier--often referred to as "factors." And by providing short-term credit that optimizes working capital and provides liquidity to both parties, SCF offers distinct advantages to all participants. While suppliers gain quicker access to money they are owed, buyers get more time to pay off their balances. On either side of the equation, the parties can use the cash on hand for other projects to keep their respective operations running smoothy.
