No day malware, also understood as zero hour malware or zero day attacks, is a type of malware that takes benefit of a previously unidentified software vulnerability. Attackers who have the ability to make use of these vulnerabilities can get to a system or network without any detection. This makes zero day malware a severe hazard to individuals and services alike.
Traditional malware, on the other hand, is malware that is well-known and has been around for a long time. Although traditional malware can still be dangerous, it is not as difficult or sneaky to discover as no day malware. https://tastykoreachannel.com/?p=240
