readelf and objdump are both excellent utilities if you are on a Unix box. Both are provided by Cygwin. readelf will give you a good overview of the ELF header information, section headers. You can also use it to get relocation and symbol information. Overall, readelf can give greater detail on the contents of an … Read more

I stumbled across this question and thought it deserved an answer. Have elf.h handy. You can find it on the internet.

Pokemon Red/Blue were the first of the series and had so many other glitches that Nintendo would normally kick out of lot-testing, that I wonder how it got through. The scroll screen shift … Read more
JNZ is short for “Jump if not zero (ZF = 0)”, and NOT “Jump if the ZF is set”. If it’s any easier to remember, consider that JNZ and JNE (jump if not equal) are equivalent. Therefore, when you’re doing cmp al, 47 and the content of AL is equal to 47, the ZF is … Read more
You can absolutely make a c program from assembler. The problem is it may not look like what you are thinking, or maybe it will. My PIC is rusty but using another assembler, say you had add r1,r2 In C lets say that becomes r1 = r1 + r2; Possibly more readable. You lose any … Read more
You cannot get the exact code, but you can get a decompiled version of it. The most popular (and best) tool is Reflector, but there are also other .Net decompilers (such as Dis#). You can also decompile the IL using ILDASM, which comes bundled with the .Net Framework SDK Tools.
Welcome to the wider world of defensive programming. There are a couple of options, but I believe all of them depend on some form of obfuscation; which, although not perfect, is at least something. Instead of a straight string value you can store the text in some other binary form (hex?). You can encrypt the … Read more
Try these: Deserialize data: analyze how it’s compiled your exe (try File Analyzer). Try to deserialize the binary data with the language discovered. Then serialize it in a xml format (language-indipendent) that every programming language can understand Analyze the binary data: try to save various versions of the file with little variation and use a … Read more
