Abstract
A technique for finding malicious code such as viruses in an executable binary file converts the executable binary to a function unique form to which function unique forms of virus code may be compared. By avoiding direct comparison of the expression of the viral code but looking instead at its function, obfuscation techniques intended to hide the virus code are substantially reduced in effectiveness.
