A Zero-Day Attack is a cyberattack that exploits a software vulnerability that is unknown to the vendor or has no available security patch at the time of exploitation. Because the flaw is undiscovered or unpatched, attackers can take advantage of it before developers have a chance to fix it.
Zero-day attacks are considered highly dangerous because they can bypass traditional security measures and cause significant damage before detection or mitigation.
For example:
Hackers exploit a newly discovered security flaw in a web browser before the company releases an update.
A malware campaign uses an unknown vulnerability in an operating system to gain unauthorized access.
Attackers target a business application using a security weakness that has not yet been patched.
Common technologies and concepts related to Zero-Day Attacks include:
- Vulnerability Exploits
- Cybersecurity
- Patch Management
- Threat Intelligence
- Malware
- Penetration Testing
- Security Updates
- Intrusion Detection Systems
