zero dayzero day attack occurs when hackers exploit a vulnerability in hardware or software that is unknown to the vendor. An attacker discovers the vulnerability, swiftly creates an exploit, and uses it to launch an attack. Zero-day attacks are severe security threats with high success rates as businesses do not have defenses in place to detect or prevent them.

 

A zero-day target attack typically goes after vulnerabilities in web browsers or Wi-Fi networks. It can also be launched via email by attaching files that exploit software vulnerabilities, such as Microsoft 365 applications and Adobe Flash Player. An attack will commonly target major enterprises, government departments, senior executives, hardware, and connected devices, as well as home users that operate a vulnerable system to compromise machines and build botnets.

 

Where Does the Term "Zero Day" Come From?

 

A zero-day attack is so-called because it occurs before the target is aware that the vulnerability exists. The attacker releases malware before the developer or vendor has had the opportunity to create a patch to fix the vulnerability.

 

However, the term "zero day" comes from the world of pirated digital media. A pirated version of a movie, music, or software is referred to as "zero day" when it becomes available at the same time or before the official release. In other words, the pirated version is published zero days after the official version.

Therefore, a zero-day vulnerability is a security risk in a piece of software that is not publicly known about and the vendor is not aware of. A zero-day exploit is the method an attacker uses to access the vulnerable system.

 

 

What is the Timeline After Exploitation?

 

A zero-day attack begins with a software developer releasing vulnerable code that is spotted and exploited by a malicious actor. The attack is then either successful, which likely results in the attacker committing identity or information theft, or the developer creates a patch to limit its spread. As soon as a patch has been written and applied, the exploit is no longer referred to as a zero day exploit.

The timeline of zero-day exploitation has been split into seven separate stages by security researchers Leyla Bilge and Tudor Dumitras from vulnerability introduction to security patch. They are as follows:

Stage 1
Vulnerability introduced: A developer creates software that, without them realizing, contains vulnerable code.

Stage 2
Exploit released: A malicious actor discovers the vulnerability before the developer realizes it exists or before they have been able to fix or patch it. The hacker then writes and deploys an exploit code while the vulnerability is still open.

Stage 3
Vulnerability discovered: The vendor becomes aware of the vulnerability but does not have a patch available.

Stage 4
Vulnerability disclosed: The vendor and/or security researchers announce the vulnerability publicly, which advises users and attackers of its existence.

Stage 5
Antivirus signatures released: If attackers have created zero-day malware targeting the vulnerability, then antivirus vendors can quickly identify its signature and provide protection against it. However, systems may remain exposed if there are other ways of exploiting the vulnerability.

Stage 6
Security patch released: The vendor releases a public fix to close the vulnerability. How long this takes to arrive depends on the complexity and how much of a priority it takes in their development process.

Stage 7
Security patch deployment completed: Releasing a security patch does not provide an instant fix as it can take time for users to deploy it. For this reason, organizations and individual users should switch on automatic software updates and take notice of update notifications.

Systems are vulnerable to attack through the entire process from stages 1 to 7, but a zero-day attack can only occur between stages 2 and 4. Further attacks can occur if the vulnerability remains unprotected. Zero-day attacks are rarely discovered quickly enough to prevent substantial damage. It can typically take days, months, and even years before a developer realizes the vulnerability existed and led to an attack and data breach.

 

Examples of Famous Zero Day Attacks

 

A zero-day attack can happen to any company at any time, often without them realizing. High-profile examples of zero-day attacks include:

  1. Sony Pictures: Potentially the most famous zero-day attack took down the Sony network and led to the release of its sensitive data on file-sharing sites. The attack, in late 2014, saw the leak of information around upcoming movies, the company’s business plans, and personal email addresses of senior executives.
  2. RSA: Another highly public zero-day attack saw hackers use an unpatched vulnerability in Adobe Flash Player to gain access to the network of security firm RSA in 2011. The attackers sent emails attached with Excel spreadsheets, which contained an embedded Flash file that exploited the zero-day vulnerability, to RSA employees. When employees opened the spreadsheet, it gave the attacker remote control of the user’s computer, which they used to search for and steal data. That information turned out to be related to its SecurID two-factor authentication products that employees use to access sensitive data and devices.
  3. Operation Aurora: In 2009, a zero-day exploit targeted the intellectual property of more than 20 major global organizations, including Adobe Systems, Blackberry, Dow Chemical, Google, Morgan Stanley, and Yahoo. It exploited vulnerabilities in Internet Explorer, various other Windows software versions, and Perforce, which Google used to manage its source code. The attack aimed to gain access to and modify source code repositories at high-tech organizations.

 

How to Protect Against Zero Day Attacks

 

Fortinet protects businesses against zero-day attacks by helping them prevent known threats, then detect and mitigate potential unknown malicious activity.

Our products provide advanced threat detection technologies that examine network traffic, users, and content to identify unknown threats. For example, sandboxing enables the observation of potentially malicious software without affecting the network, while botnet detection flags patterns that could suggest command-and-control activity.

While a zero-day attack, by its very definition, is impossible to patch, there are methods that allow organizations to defend against them.

  1. Vulnerability scanning: Solutions that scan for vulnerabilities can simulate attacks on software code, review code for errors, and attempt to find new issues that have been introduced in a software update. However, this approach will not detect all zero-day exploits, and scanning alone is not enough. Businesses need to act quickly on the results of a scan and review code to prevent an exploit.
  2. Patch management: Deploying software patches as soon as possible after discovering a software vulnerability can reduce the risk of an attack. However, it cannot prevent an attack if the hacker creates their exploit quicker than the patch is deployed. The longer the patch process takes, the higher the risk of a zero-day attack occurring.
  3. Input validation: Input validation, or data validation, is the proper testing of any input supplied by an application or user to prevent improperly formed data from entering a system. It protects organizations through the vulnerability scanning and patch management process and enables them to respond to new threats in real time. One of the best ways to prevent zero-day attacks is to deploy a web application firewall (WAF) on the network edge to review incoming traffic and filter out malicious inputs that could target security vulnerabilities.
  4. Zero-day initiative: The zero-day initiative is a program that rewards security researchers for disclosing vulnerabilities rather than selling them on the black market. Its aim is to create a community of vulnerability researchers who discover software problems before hackers do. In addition, organizations also offer bug bounty programs that compensate individuals for reporting vulnerabilities to them.

 

Types of Strategies

 

To remain vigilant against the threat of zero-day attacks, businesses must have a strategy in place. The key elements of this strategy need to be:

  1. Stay informed: Being proactive and staying informed on the latest risks in the threat landscape is a vital first step in preventing zero-day attacks. This includes deploying comprehensive security software that will block known and unknown threats. It also includes employees practicing safe and secure online habits and configuring security settings for their browsers and systems.
  2. System updates: Ensuring systems are up to date is crucial to protecting a business from the risk of zero-day attacks. This includes having the latest features installed, removing outdated or defunct features, updating drivers, fixing bugs, and filling potential holes in security.
  3. Fortinet next-generation firewall (NGFW) product: Traditional antivirus software cannot effectively protect businesses from zero-day threats. Instead, businesses need to look for solutions that block unknown zero-day malware. The Fortinet NGFW does this by combining deeper inspection capabilities that identify advanced attacks, malware, and threats. It not only blocks malware but also provides the flexibility to evolve with the threat landscape and keep organizations’ networks secure as new threats emerge.

zero dayYou’ve probably heard about zero day vulnerability but do you have any idea what it is? It’s actually a software security flaw, which the software vendor knows, but can’t fix it since there’s no available patch to fix it. It’s easy for cybercriminals to exploit it.

During these modern times, vulnerabilities are flaws that were not intended and are discovered in operating systems and software programs. Vulnerabilities could be the consequence of incorrect security or computer configurations as well as programming mistakes. If they aren’t addressed, the vulnerabilities will open up security holes that could be exploited by cybercriminals.

Why do zero day vulnerabilities threaten cybersecurity?

Hackers create codes that will target a certain security weakness. They will add it to a malware that is referred to as zero-day exploit. This malicious software will make the most out of the vulnerability so as to cause a certain unintended behaviour or to compromise a computer system. In many instances, a patch that comes from the software developer will be able to fix this.

 

 

What if your computer is infected? An exploit malware could easily steal your data, which will allow hackers to have an unauthorized control over your computer. Software could also be used in different ways that they weren’t supposed to do in the first place.  These includes the installation of other malware that could corrupt your files or access the contact list and then send some spam messages using your account. It may also install spyware that’s designed to steal confidential information from your computer.

If you are an avid computer user, a vulnerability will have serious cybersecurity risks since exploit malware could infect your computer through the harmless activities you do when browsing the web such as when you’re viewing a website, playing a compromised media, or opening an infected message.

How do you know if the vulnerability is a zero day?

Zero-day is a new software vulnerability. It simply means that the software developers have zero day to fix the problem since they don’t have the means to do so even if they know that the flaw exists. This is why it can easily be exploited by cybercriminals.

When the vulnerability becomes known in public, the vendor need to work right away to repair the issue in order to protect the users. However, the software vendor might fail to provide a patch before cybercriminals may manage to take advantage of the security hole. That’s referred to as the zero day attack.

How can you protect yourself against zero day vulnerabilities?

Zero-day vulnerabilities will present serious risks to Computer security – Wilmington NC. If you encounter it, you’ll end up dealing with possible damage to your personal data or your computer. If you want to keep your computer safe, then you have to go for a more proactive zero-day managed IT services.
