Exploit Computer Viruses

An "exploit" is a short piece of code or script that uses a computer security vulnerability in software or an operating system to perform certain malicious actions. The most famous exploit is called 'Incorrect MIME Header exploit' or 'Iframe'. The Incorrect MIME Header exploit allows one to automatically run an e-mail attachment on certain unpatched versions of Microsoft e-mail and web browsing software. This exploit is widely used by famous e-mail worms - Nimda, Klez, Yaha, Bugbear, Bridex and many others. When a recipient of an infected e-mail only previews an infected message, an infected attachment is activated by the Iframe exploit and a computer becomes infected.
