An achievement in the field of computer security is an element of a program allowing an individual or a Malware to exploit a security vulnerability in an operating system or software. Worms exploit remote vulnerabilities to automatically spread from one PC to another within a network. For example, the Conficker worm, to spread itself, exploits the vulnerability (MS08-067) within the Windows operating system.
Prévention et protection
