typical simple encryption done by smartassembly. in the past, purecrypter tried to remain undetected by its own methods. However, purecrypter uses as stage1 a downloader which is encrypted with smartassembly.
As stage2 an embedded resource file is used to deploy the download and by runpe the final stage.
