Clicking on the link will download the malicious payload or takes the user to a site that would automatically download the malware. This technique is often used by organized cyber-criminal organizations. Embedding exploit kits in malvertisements and malicious sites.
In this scenario, bad actors have successfully compromised a web site and injected a malicious code that would redirect a visitor to the exploit kit server. Compromising a system, network, or server. For example, applying brute force and then using the exploit to execute the attack. Heartbleed Shellshock Stuxnet a worm that exploited multiple vulnerabilities Aurora an organized attack that exploited several vulnerabilities BlueKeep Vulnerability CVE Have a solid vulnerability management program and a patching program.
For example, update software ASAP, especially critical security release updates. Cyber security awareness training focused on social engineering, recognizing phishing and spear-phishing campaigns, and avoiding malicious websites. Applying micro-segmentation and least privilege, especially in high-value systems, to make it more difficult and expensive for attackers to reach their targets.
Threat intelligence, auditing and monitoring of user activity, connectivity, and anomaly detection. Have a thought-out disaster recovery and back-up plan. Real-time visibility enables security, IT ops, and networking teams to model and understand the normal traffic and application behavior. It helps them detect new connectivity and unusual failed attempts to connect to a workload, which could be indicators of an attack. Micro-segmentation is a preventative control. Micro-segmentation as a compensating control in the event of an attack.
When a zero-day is publicly disclosed, and no patch is available or if patching is not operationally feasible, an organization can use process-level segmentation to lock down traffic between workloads and between workloads and users only to specific ports, protocols and services.
Learn more on how to stay protected from the latest Ransomware Pandemic. What is Zero Day Attack? What is a Software Vulnerability? Zero Day Attacks If a hacker manages to exploit the vulnerability before software developers can find a fix, that exploit becomes known as a zero day attack.
If you stay tuned to the news and you pay attention to releases from your software vendors, you may have time to put in security measures or respond to a threat before it gets exploited. Keep your systems updated Developers work constantly to keep their software updated and patched to prevent the possibility of exploitation. The best approach here is to enable automatic updates, so your software is updated routinely, and without the need for manual intervention.
Employ additional security measures Ensure that you are using security solutions that protect against zero day attack because these security measures may not be enough to fully protect you from a zero day attack. What is Malware? What is Cybersecurity?

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. A zero-day attack is when hackers leverage their zero-day exploit to commit a cyberattack, oftentimes resulting in problems like identity theft or data loss.
What makes a vulnerability a zero-day? How do zero-day attacks work? 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. Keep software up to date to ensure security patches are in place and to reduce the risk of malware infection.
Use a firewall to monitor and block suspicious activity, such as zero-day exploits. Educate yourself on zero-day exploits and seek out solutions when zero-day vulnerabilities are discovered. Consider using antivirus software to protect against both known and unknown threats. Just consider these recent and headline-making examples of zero-day exploits. Google Chrome, : Google Chrome fell victim to several zero-day threats, attributed to a bug in JavaScript.
