What is no day malware?
No day malware is malware that is not yet understood to anti-virus software vendors or companies. It makes use of vulnerabilities in software or hardware that have actually not yet been patched or fixed. The term "no day" originates from the reality that when the malware is found, there is zero time to spot the vulnerabilities prior to attackers can exploit them.
Zero day malware is often used in targeted attacks versus particular organizations or people. The assaulters will carefully select their targets, and then craft their malware to specifically exploit the vulnerabilities in those target's systems. This makes absolutely no day malware really hard to spot and protect against.
Among the most well-known examples of absolutely no day malware is the Stuxnet worm, which was used to attack commercial control systems. Stuxnet was able to spread itself through USB drives and contaminated networks of computers, without being spotted by anti-virus software. https://sendtomark.co.uk/?p=157 It then particularly targeted Siemens commercial control systems, and caused physical damage to centrifuges in Iran.
