A zero-day also known as 0-day vulnerability is a computer-software vulnerability that is unknown to, or unaddressed by, those who should be interested in mitigating the vulnerability including the vendor of the target software.

Until the vulnerability is mitigated, hackers can exploit it to adversely affect computer programs, data, additional computers or a network.

The term "zero-day" originally referred to the number of days since a new piece of software was released to the public, so "zero-day" software was software that had been obtained by hacking into a developer's computer before release.

Eventually the term was applied to the vulnerabilities that allowed this hacking, and to the number of days that the vendor has had to fix them.

The more recently that the vendor has become aware of the vulnerability, the more likely that no fix or mitigation has been developed.

Even after a fix is developed, the fewer the days since then, the higher the probability that an attack against the afflicted software will be successful, because not every user of that software will have applied the fix.

For zero-day exploits, unless the vulnerability is inadvertently fixed, e. Zero-day attacks are a severe threat.

Malware writers can exploit zero-day vulnerabilities through several different attack vectors. Sometimes, when users visit rogue websites , malicious code on the site can exploit vulnerabilities in Web browsers.

Web browsers are a particular target for criminals because of their widespread distribution and usage.

Criminals can engineer malware to take advantage of these file type exploits to compromise attacked systems or steal confidential data. The time from when a software exploit first becomes active to the time when the number of vulnerable systems shrinks to insignificance is known as the Window of Vulnerability WoV.

Thus the formula for the length of the Window of Vulnerability is: t 2 — t 1b. Note that t 0 is not the same as Day Zero.

For example, if a hacker is the first to discover at t 0 the vulnerability, the vendor might not learn of it until much later on Day Zero.

This implies that the software vendor was aware of vulnerability and had time to publish a security patch t 1a before any hacker could craft a workable exploit t 1b.

By not disclosing known vulnerabilities, a software vendor hopes to reach t 2 before t 1b is reached, thus avoiding any exploits.

However, the vendor has no guarantees that hackers will not find vulnerabilities on their own. Furthermore, hackers can analyze the security patches themselves, and thereby discover the underlying vulnerabilities and automatically generate working exploits.

In practice, the size of the WoV varies between systems, vendors, and individual vulnerabilities. It is often measured in days, with one report from estimating the average as 28 days.

Zero-day protection is the ability to provide protection against zero-day exploits. Since zero-day attacks are generally unknown to the public it is often difficult to defend against them.

Zero-day attacks are often effective against "secure" networks and can remain undetected even after they are launched.

Thus, users of so-called secure systems must also exercise common sense and practice safe computing habits.

Many techniques exist to limit the effectiveness of zero-day memory corruption vulnerabilities such as buffer overflows.

These protection mechanisms exist in contemporary operating systems such as macOS , Windows Vista and beyond see also: Security and safety features new to Windows Vista , Solaris , Linux , Unix , and Unix-like environments; Windows XP Service Pack 2 includes limited protection against generic memory corruption vulnerabilities [13] and previous versions include even less.

Desktop and server protection software also exists to mitigate zero-day buffer overflow vulnerabilities. Typically these technologies involve heuristic termination analysis —stopping them before they cause any harm.

It has been suggested that a solution of this kind may be out of reach because it is algorithmically impossible in the general case to analyze any arbitrary code to determine if it is malicious, as such an analysis reduces to the halting problem over a linear bounded automaton , which is unsolvable.

It is, however, unnecessary to address the general case that is, to sort all programs into the categories of malicious or non-malicious under most circumstances in order to eliminate a wide range of malicious behaviors.

It suffices to recognize the safety of a limited set of programs e. This does require the integrity of those safe programs to be maintained, which may prove difficult in the face of a kernel level exploit.

Zero-day worms take advantage of a surprise attack while they are still unknown to computer security professionals.

Recent history shows an increasing rate of worm propagation. Well designed worms can spread very fast with devastating consequences to the Internet and other systems.

Differing ideologies exist relative to the collection and use of zero-day vulnerability information. Many computer security vendors perform research on zero-day vulnerabilities in order to better understand the nature of vulnerabilities and their exploitation by individuals, computer worms and viruses.

Alternatively, some vendors purchase vulnerabilities to augment their research capacity. While selling and buying these vulnerabilities is not technically illegal in most parts of the world, there is a lot of controversy over the method of disclosure.

A German decision to include Article 6 of the Convention on Cybercrime and the EU Framework Decision on Attacks against Information Systems may make selling or even manufacturing vulnerabilities illegal.

In general these rules forbid the public disclosure of vulnerabilities without notification to the vendor and adequate time to produce a patch.

A zero-day virus also known as zero-day malware or next-generation malware is a previously unknown computer virus or other malware for which specific antivirus software signatures are not yet available.

Traditionally, antivirus software relies upon signatures to identify malware. This can be very effective, but cannot defend against malware unless samples have already been obtained, signatures generated and updates distributed to users.

Because of this, signature-based approaches are not effective against zero-day viruses. Most modern antivirus software still uses signatures, but also carries out other types of analysis.

In code analysis , the machine code of the file is analysed to see if there is anything that looks suspicious. Typically, malware has characteristic behaviour and code analysis attempts to detect if this is present in the code.

Although useful, code analysis has significant limitations. It is not always easy to determine what a section of code is intended to do; particularly if it is very complex and has been deliberately written with the intention of defeating analysis.

But the software vendor may fail to release a patch before hackers manage to exploit the security hole.

Zero-day vulnerabilities present serious security risks, leaving you susceptible to zero-day attacks, which can result in potential damage to your computer or personal data.

Your first line of defense is to be proactive by using comprehensive security software, like Norton Security, that protects against both known and unknown threats.

Your second line of defense is to be reactive and immediately install new software updates when they become available from the manufacturer to help reduce the risk of malware infection.

Software updates allow you to install necessary revisions to the software or operating system. These might include adding new features, removing outdated features, updating drivers, delivering bug fixes, and most important, fixing security holes that have been discovered.

Follow this security checklist to be sure you are doing everything you can to help keep your information protected from the security risks associated with zero-day vulnerabilities:.

Stuxnet — a type of zero-day vulnerability — was one of the earliest digital weapons used. Stuxnet is a highly infectious self-replicating computer worm that disrupted Iranian nuclear plants.

The threat took control of computers. It altered the speed of centrifuges in the plants and shut them down. They discovered that Stuxnet is a well-crafted computer worm that only a national government could create to control large-scale industrial facilities.
