What is absolutely no day malware?

Zero day malware is malware that is not yet understood to anti-virus software suppliers or companies. It makes use of vulnerabilities in software or hardware that have not yet been covered or repaired. The term "no day" originates from the reality that when the malware is discovered, there is zero time to spot the vulnerabilities before enemies can exploit them.

https://cleardex.io/?p=1350 Absolutely no day malware is typically used in targeted attacks against particular companies or individuals. The opponents will carefully choose their targets, and after that craft their malware to specifically exploit the vulnerabilities in those target's systems. This makes no day malware extremely tough to discover and protect against.

Among the most famous examples of no day malware is the Stuxnet worm, which was utilized to attack industrial control systems. Stuxnet was able to spread itself through USB drives and contaminated networks of computer systems, without being detected by anti-virus software. It then specifically targeted Siemens industrial control systems, and triggered physical damage to centrifuges in Iran.

No day malware is a severe risk to individuals and companies. It is essential to keep your systems current with the current security patches, and to be familiar with the current dangers.
