For example, the program might check to see if some pointer value stored in the global data section is NULL, and if so, allocate memory and overwrite that NULL pointer with the allocation.
When programs execute, they tend to modify global data structures to indicate that things have been initialized already. One complication in dumping executable images out of memory is that, if you want the end result to be a working EXE that you can run (or in this case, a working DLL that can be loaded into memory), you need to be meticulous about the precise time to dump. Many tools exist such as Scylla, LordPE, ImpRec and its dump plugin, etc. Given that EXEs and DLLs share the same file format, and are loaded within a process' address space in an identical fashion, the same tools and procedures for dumping an EXE out of memory also apply to dumping a DLL out of memory. If the DLL is encrypted separately from or regardless of the network traffic's encryption or lack thereof, then these ideas won't give you an unencrypted DLL, so you might have to fall back on the idea of dynamically dumping the DLL out of memory at some point. If the traffic is encrypted (say, via HTTPS) but the DLL is not, perhaps you can place a breakpoint inside of the HTTPS library to retrieve the unencrypted traffic. Since you say it's downloading the DLL off of the network, perhaps you can just read the raw contents of the DLL from the network traffic? If the traffic, and the DLL, are unencrypted, this should be easy (you can use Ethereal, for example). If you still can't find the file you need, you can leave a "message" on the webpage.I had written up a lengthy answer about some of the subtleties of dumping executables and DLLs before I realized that you may have simpler solutions available.If yes, please check the properties of these files, and you will know if the file you need is 32-bit or 64-bit. If you encounter this situation, check the file path to see whether there are any other files located in. There is a special case that, the operating system is a 64-bit system, but you are not sure whether the program is 32-bit or 64-bit. If your operating system is 32-bit, you must download 32-bit files, because 64-bit programs are unable to run in the 32-bit operating system. (Method: Click your original file, and then click on the right key to select "Properties" from the pop-up menu, you can see the version number of the files) If your original file is just corrupted but not lost, then please check the version number of your files. If you know MD5 value of the required files, it is the best approach to make choice Tip: How to correctly select the file you need
