Thanks. And,

Difficulty: ?

Only experimenting like I said, just wondering whether its worth totally re-basing the image if relocs are present.

Difficulty: ? <-- No not really.So you know I can just give you my opinion.

-no IAT redirection

-no AntiDump / dump protection feature

-no manipulation detection / CRC / PE

You should also insert more [self] and debug checks.

So keep going maybe you next one will be harder.

NullPointerException

also you should pack bigger file if you are developing your own protector so we can fully test it.

As for protection you should do what lcf said, plus:

1) try to hide the jmp to oep

2) add some primitive obfuscation (by using jumps)

3) dont make the code too linear: use calls inside calls to hide what your packer does. It's stupid but effective

regarding antidebugs try to develop your own way to detect debuggers: altough they are more or less all known, try to make some little tricks (plugin detection, hook of patches made by plugins detection etc)

last week i found a paper from blackhat explaining malware protection but i cant find it anymore. was nice for some inspiration :)
