Hmmm.... don't think so. Unless marked with a Copyright it is NOT. Also private companies often have legal clauses to show that anything you create while employed by them becomes their property not yours.

But not all Countries have the same laws. We in California just happen to have more Sharks (lawyers) probably then some Countries have so they love to fight over stupid minor things

well, due to the fact that most likely the code was never in public dir, it was same if he was coding it at work.
he published the exe, thus the company has rights to it.
not the source itself.
if he had left the source somewhere, it would have been otherwise.

It does depend on the employment contract or employee hadnbook. However, in general anything developed on company time or with company equipment is the property of the company. This includes source code that is then compiled. The company not only owns the compiled product but also the source code. Inventions are handled slightly different, the normal procedure is that the inventors assign the patent to a company, however, AfAIK, the company itself cannot be an inventor.

Put delete inhibit on the temp folder and it should stay even after the script finishes.




Not unless you are using one of the early versions of KiXcrypt which did not have much in the way of hack defeats. The "delete inhibit" exploit was fixed in Version 2.08b released 1st Feb 2002. It is noted in the version history and the warning messages as the "Russ Exploit" in recognition of the guy that found and reported it to me privately

If you look at the version info you will see that quite a few exploits have been identified and defeated.

Certainly by the time I got around to the console-less versions these simple exploits were defeated.

Specifically regarding delete inhibit, KiXcrypt performs a few checks to ensure that it will be able to both overwrite and remove the temporary file before it starts to write real script code out.

If the "-x" flag was used on the package creation then it is more secure as the primary script is never commited to disk. A small bootstrap script is written and the primary script is passed directly to it for execution.

It is not impossible to defeat KiXcrypt packages but it is (I believe) sufficiently difficult to be "good enough".

I tried that.
at least with newer kixcrypt versions it does not work.
seems like kixcrypt tries to first create empty file and then delete it before writing the actual script there.





thanks for proving my case
