disassembly

THe elf file is static linked and currently the objdump's output is something like: Disassembly of section: .init: xxxxxx Disassembly of section: .plt: xxxxxx Disassembly of section: .text: xxxxxx basically what I want to achieve is "elf-file -(disassemble by objdump)-> assemble file --(re-compile)--> same functionality " I don't need the re-compiled binary has the binary content same as the original one, only same functionality is enough. After a quick search, basically the answer is no , and they argued that disassemble file lost some stuff like symbolic information or others, but I think by

As an intro to learning Arm assembly, I'm trying to recreate disassembled functions in a higher level language. However I'm confused by the following bit of assembly: 0000315e 2101 movs r1, #1 00003160 e8dff000 tbb [pc, r0] 00003164 030e lsls r6, r1, #12 00003166 0907 lsrs r7, r0, #4 00003168 050b lsls r3, r1, #20 0000316a 2106 movs r1, #6 0000316c e008 b.n 0x3180 0000316e 2102 movs r1, #2 00003170 e006 b.n 0x3180 00003172 2103 movs r1, #3 00003174 e004 b.n 0x3180 00003176 2104 movs r1, #4 00003178 e002 b.n 0x3180 0000317a 2105 movs r1, #5 0000317c e000 b.n 0x3180 0000317e 2100 movs r1, #0

I think what I need is something the .net folks call "transparent dynamic proxy", but all the implementations I've seen this far (Castle DynamicProxy, Spring.NET AOP, etc) require me to do at least one of these: Declare intercepted method as virtual Wrap class and create instances of the wrapper instead of wrapped class Change inheritance or implement interfaces Obviously, if both caller and callee are nonvirtual and from thirdy-party closed source libraries, which is the case, there is nothing I can do. If C# were a dynamic language like Python I would do something like this: foo =

Article can be found here . I'm reading up on smashing the stack and have found myself to be getting stuck on example3.c. 0x80004a3 <main+19>: call 0x8000470 <function> 0x80004a8 <main+24>: addl $0xc,%esp 0x80004ab <main+27>: movl $0x1,0xfffffffc(%ebp) 0x80004b2 <main+34>: movl 0xfffffffc(%ebp),%eax The author indicates that we want to skip from 0x80004a8 to 0x80004b2 and that this jump is 8 bytes; how has the author determined this is 8 bytes? I have recreated the code and sent it through objdump and found that it's not 8 bytes (I am on a 64 bit machine but I've made sure to compile using 32

as titled, like function calls, application behavior when running You have a few options. "dexdump" is included with the SDK and is present on the device. With the "-d" option it produces a no-frills disassembly of the methods. The output format is intended to mimic the "--dump-to" output format of dx. "smali/baksmali" is an assembler/disassembler for Dalvik bytecode. It's open source , and is probably the most complete solution. "dedexer" is a disassembler that produces Jasmin-like output. It's also open source . As far as I know, nobody has written a program that attempts to convert Dalvik
