What is a zero-day malware attack?
Zero day malware is malware that exploits unknown and unprotected vulnerabilities. This novel malware is difficult to detect and defend against, making zero day attacks a significant threat to enterprise cybersecurity.
How zero-day attack can be detected and prevented?
Vulnerability disclosed publicly – the vendor, or security researchers, announce the vulnerability, making both users and attackers widely aware of it. Anti-virus signatures released – if attackers have created zero-day malware, anti-virus vendors can identify its signature relatively quickly and protect against it.
