How zero-day attack is detected?

A zero-day exploit tends to be difficult to detect. Antimalware software, intrusion detection systems (IDSes) and intrusion prevention systems (IPSes) can't recognize the attack signature because one doesn't yet exist. This is why the best way to detect a zero-day attack is user behavior analytics.

What is zero-day malware detection?

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.

Why is zero-day attack difficult to detect?

Zero-day attacks are by definition difficult to detect because there are currently no antivirus signatures or patches for them. To find previously undiscovered software vulnerabilities, there are numerous methods of zero-day vulnerability detection.

What is an example of a zero-day attack?

Real World Examples

In April 2017, Microsoft was made aware of a zero-day attack on its Microsoft Word software. The attackers used a malware called Dridex banker trojan to exploit a vulnerable and unpatched version of the software.
