The malware must decrypt the parts that it runs. (There's an obfuscation technique that's apparently quite strong in existence, but it produces gigabyte executables for simple 5-condition if statements you can brute force by hand, so it's ludicrously impractical.) This could be worse. It could have encrypted routines for which the commands are the decryption keys. It doesn't appear to be particularly polymorphic. If there's a BIOS/PCI dropper, it's (sadly) long gone here.
