1. Zero-day definitions:

The term “zero-day” refers to a newly discovered software vulnerability and the fact that developers have zero days to fix the problem because it has been — and has the potential to be — exploited by hackers. Sometimes written as 0-day, zero-day definitions run the gamut: A zero-day vulnerability, also known as a zero-day threat, is a flaw in security software that’s unknown to someone interested in mitigating the flaw, like a developer. A zero-day exploit is when hackers take advantage of a zero-day vulnerability for malicious reasons, oftentimes by way of malware to commit a cyberattack.

zero-day malware or more broadly as a zero-day exploit. And they might deliver this by way of social engineering tactics or phishing. Once the zero-day exploit is downloaded on devices, the zero-day attack is executed. The havoc that ensues can include: Data is stolen Hackers taking remote contro...

Individual computer users saw their bank accounts compromised after opening a Microsoft Word document containing zero-day malware.

Government agencies across Eastern Europe saw their Microsoft Windows software exploited, resulting in suspicious apps being installed, data changed, and programs compromised.

A bug in Apple’s iOS software allowed hackers to compromise devices from remote locations.

Hackers exploited a vulnerability in the video conferencing platform that allowed them to take remote control over PCs.

inally, don’t underestimate the threat of zero-day exploits. Cybercriminals will seek to exploit security holes and gain access to your devices and your personal information. They can use your information for a range of cybercrimes including identity theft, bank fraud, and ransomware. Just consid...

Oftentimes, zero-day vulnerabilities are detected when it’s too late — when they’re exploited, that is. There are some more technical ways to identify zero-day vulnerabilities, including scanning internet traffic, examining codes of incoming files, and leveraging malware detection methods. For ev...

While software developers are constantly looking to patch security vulnerabilities we see this in the form of software updates cyberattackers are constantly seeking to exploit them. And there are many types of cyberattackers, each with its own motivations: Cybercriminals or hackers are often fina...

Zero-day attacks begin with zero-day vulnerabilities, meaning flaws or holes in security software. These can result from improper computer or security configurations or programming errors by developers themselves. The whole notion of a zero-day attack is that cyber attackers exploit these vulnera...

Even as we can’t always detect these vulnerabilities, we can protect our devices and data in the event an exploit does occur. Consider these proactive and reactive security measures. Keep software up to date to ensure security patches are in place and to reduce the risk of malware infection. Limi...

Security software vulnerabilities can come in many forms, including unencrypted data, broken algorithms, bugs, or weak passwords. What makes a vulnerability a zero-day is when someone interested in mitigating the flaw is unaware of it, meaning an official patch or update to fix the flaw doesn’t e...
