What is zero day malware?

Zero day malware is malware that is not yet understood to anti-virus software application vendors or business. It exploits vulnerabilities in software application or hardware that have actually not yet been patched or fixed. The term "absolutely no day" comes from the fact that once the malware is discovered, there is no time to patch the vulnerabilities before assailants can exploit them.

Absolutely no day malware is typically utilized in targeted attacks versus specific organizations or people. The assailants will carefully pick their targets, and then craft their malware to particularly exploit the vulnerabilities in those target's systems. This makes no day malware very difficult to secure and spot against.

Stuxnet was able to spread itself through USB drives and infected networks of computer systems, without being spotted by anti-virus software application. It then particularly targeted Siemens industrial control systems, and caused physical damage to centrifuges in Iran.

No day malware is a serious danger to people and organizations. It is necessary to keep your systems current with the current security patches, and to be aware of the current hazards.
