| Research Abstract |
A rapid automatic virus detection algorithm using static code analysis is necessary.However,recent computer viruses are almost compressed into the executable compress format and are obfuscated.Thus,it is difficult to determine the characteristics of the binary code from the obfuscated computer viruses.
In this research,a method that unpacks compressed computer viruses automatically without restriction to compression type is proposed.The proposed method unpacks the common compression formats accurately 80% of the time,while unknown compression formats can also be unpacked.The proposed method is effective against unknown viruses by combining it with the existing known virus detection system like Bayesian Virus Filter.We could achieve to implement 95% detection rates and 0.02% false detection rates.
