- TACIXAT 9y agoupx -d packed.exe UPX is fairly easy to defeat, but many malicious samples will have their own packers / loaders.
- wiz21c 9y agonot alone. It's been long time since I've hacked anything but first one had fun by storing the decompression code into the interrupt table (yes, there). Or by making sure the decompression routine used accurate timings (so that if you fiddle with step by step execution it fails). Or calculating jump's based on values on the screen (that is, not the values show by your debugger). That way the decompiler should, at least, be able to execute the code. But that was before the protected mode in intel. My knowledge stops there.
