just a wild guess but maybe something like printf("what to put \n") will work . I never accused you of having a similar backdoor in your code, I only said "hey look, I guess not having networking code in the program isn't as strong of proof that it is not backdoored as you thought" Which is 100% true. It is stupid to buy a script if you don't know what it is doing and it has not been checked out by enough people who can figure it out. If it is posted publicly anyone can check it out and any backdoor will be quickly found. I could ask a dozen people I know who know python to look it over and let me know if it is safe or not and pass that on to the forum. I am sure a lot of people here either know python or know people who do, and that they could do the same. I point out that it is not necessarily obvious if a script is capable of transmitting data over the internet, that is all that I demonstrated. Even you couldn't figure out what the script was doing until I correctly commented every line of it, it seem that you actually thought the initial bullshit comment I left explaining away the call to unpack was legitimate, even when I intended for my initial post to clearly demonstrate the backdoor. Do you think someone with no programming or command line experience is going to be able to find what was going on there, or will they think it looks innocent and be satisfied with the detailed if partially incorrect (intentionally so) comments I left? No I said 100% of users who use your software will not be able to identify something like the backdoor I demonstrated in a different language. Because if they could identify it they would program the tool themselves. The solution to keep everyone secure and happy, is to get donations for your work and let the code be publicly audited, because I guarantee you if I read the Ruby script I wrote but someone else had written it, that I would have noticed what was going on. Someone who knows Python but not Ruby looked at it and had a difficult time to figure it out even with most of it commented correctly, I think that goes to show that you should know the language well enough to audit code or be confident that others who know the language well enough to audit code have done so, before you run scripts from anyone.
