Zero Day - 10 things to know with detail

• Definition: Zero day refers to a computer vulnerability that is unknown to the software vendor or security community. It is called "zero day" because once the vulnerability is discovered, the vendor has zero days to fix it before attackers can exploit it.
• Exploitation: Zero day vulnerabilities are highly sought after by cybercriminals and state-sponsored hackers because they provide an opportunity to launch targeted attacks without detection. These attacks can range from stealing sensitive data to disrupting critical infrastructure.
• Detection: Detecting zero day vulnerabilities is challenging because they are not known to security researchers or vendors. Attackers can exploit these vulnerabilities for months or even years before they are discovered and patched.
• Disclosure: When a zero day vulnerability is discovered, ethical hackers or security researchers may choose to disclose it to the vendor so that a patch can be developed. However, some researchers may sell the vulnerability to governments or cybersecurity firms for profit.
• Patching: Once a zero day vulnerability is disclosed to the vendor, they must develop and release a patch to fix the issue. This process can take time, leaving users vulnerable to attacks in the meantime.
• Mitigation: In the absence of a patch, users can mitigate the risk of a zero day attack by implementing security best practices such as using strong passwords, keeping software up to date, and using endpoint protection solutions.
• Exploitation methods: Zero day vulnerabilities can be exploited through various methods, including phishing emails, malicious websites, and malware. Attackers may use these techniques to gain access to a system and carry out their malicious activities.
• Impact: Zero day attacks can have serious consequences for individuals, businesses, and governments. They can lead to data breaches, financial losses, reputational damage, and even national security threats.
• Vulnerable software: Zero day vulnerabilities can exist in any type of software, including operating systems, web browsers, mobile apps, and IoT devices. No software is immune to these types of attacks.
• Prevention: To protect against zero day attacks, organizations should implement a multi-layered cybersecurity strategy that includes regular security updates, intrusion detection systems, network segmentation, and employee training. It is also essential to collaborate with the security community to stay informed about emerging threats and vulnerabilities.
