ExeInfoPE also supports plugins. Sometimes you may need to access HDD, memory or applications in binary mode. This is where hex editors come in handy, as exemplified by HxD. This program is free and frequently updated, supports popular formats, is good for searching and offers a user-friendly UI.
There are other well-executed features, such as the ability to remotely erase zerofill files. There is also a portable version for easy storage on a flash drive. This hex editor has a long history, but it is still supported by its devs. The Norton Commander-like interface might scare off a younger crowd, but it is easy to get used to. A useful program for malware analysis. It also enables you to work with resources. In other words, this is a versatile antivirus tool for initial sample analysis.
If you want to, you can view sections in hex mode and disassemble them into regular assembler mnemonics. PE-bear has a user-friendly UI and file-comparing utility. So, if you find a bug, you can fix it yourself. This program emulates working with a network. When studying malware samples, you often need to see all their Internet activities: monitor DNS and HTTP queries, sniff traffic and identify IP addresses of the controlling servers for example, if you are dealing with a ransomware bot.
Fakenet-NG is fully supported with frequent updates, so this utility can be used in the latest operating sytems. It would be hard to perform reverse engineering without programs from Sysinternals that monitor how applications access the filesystem and processes. ProcessExplorer shows all processes in a hierarchical tree view, so you can easily see their spawning order.
You can also see which dynamic libraries they use, as well as their priority, digital signatures, processor usage and much more. A handy utility for monitoring registry changes. RegShot takes snapshots of the registry before and after you do some system or software changes. You can see which ports it accesses both local and remote , together with protocols, process identifiers and transmitted packet counters.
Overall, this is one of the most useful tools for any hacker! A popular program for editing resources, including manifests, icons, text dialog lines, cursor info and much more. We have covered the main utilities used for most reverse engineering tasks. I think this should be enough for a beginner. Your own list will grow as you progress. Many reverse engineers end up writing their own targeted programs, plugins and scripts.
With the right tools, you can examine the inner workings of a program and experiment with reverse-engineering. You'll need have a firm grasp on assembly programming and hex code to get started, and a disassembler app. Once you're familiar with the code, you can modify the DLLs so their corresponding programs never have to be registered or purchased.
Open the application in a disassembler. Find the counter function you want to change. Set a break-point on the counter. Change the counter code. Recompile the software. Did this summary help you?

If you want to crack most software, you will need to have a good grasp on assembly , which is a low-level programming language.
Most assembly language is expressed through binary and hexadecimal. Install a disassembler. To examine and modify DLLs, you will need several different tools, including a disassembler. IDA Pro is a great option, as it's a disassembler and debugger. You can also try dotPeek , which is a DLL-supporting decompiler that decompiles. Here's what they all mean I'll explain how to use them later. Frequently this is the actual EXE of the main program, but in modified form.
It could also be a DLL or a key file that the program uses to register itself or check an online activation server. A cracked file has such checks removed. A drawback of a crack is it can be big sometimes many MBs since it's just a modified version of the original file. Frequently, updating a program that has been cracked will overwrite the crack, causing the program to return to it's "pre-cracked" state trial, non-functioning, etc.
Not to mention it's one of the more difficult to use along with a patch ; that is, for a n00b. It's rarely more then a few hundred KB at most and frequently contains information on what it is such as what it's for, how to use it, etc.
With a patch, you can make a crack. When you start up a patch, frequently you'll be greeted with information such as the release group's name, the cracker who made it, information on the "target file" more on that later , and so on.
In most cases, it has all the same drawbacks as a crack does listed above , except for the file size issue. Frequently a provided serial will register the software program, however it will register it with the name of the cracker or website that distributed it. A technique known as "serial fishing" is the cause of that. Sometimes a serial can be used with any information such as your own name , and sometimes it is vital to use the information provided with it name, email, company, etc.
The biggest drawback to serials is a term called "blacklisting", which will be discussed later. A keygen, in most cases, is the "best" or most sought after form of a fix. A keygen allows you to generate the correct registration data for a program using any information you like such as your name, email, company, etc without modifying anything in the actual program similar to a serial, but always just for you.
Sometimes a keygen will generate a serial for you that you can use, other times it might generate a license file that needs to be imported into the program. Keygens can have multiple uses as well. For software that requires activation that is, it needs to contact the software author or website to ensure the registration data is legit , frequently a keygen will provide the means to use the "Phone Activation" method in a program. Most every program that requires activation allows you to do so via the Internet or over the phone.
The keygen simply mimics what a person at the software company would do for you. In most cases, the pitfalls of cracks, patches and serials do not hold true with a keygen; hence why it is considered the best! The only real drawback is the cracker could possibly be off a bit in the algorithm, causing some generated keys to not work completely. Frequently the fixes are provided along with an NFO. This is an information file that tells information about the release.
For example, if you have a Patch and an NFO file, the NFO may tell you how to properly use the patch, as well as provide information on the program itself. You may also see DIZ files - these usually just contain file version information. Though handy to have and informative, they rarely need to be used in the process of "fixing" a software application.
NFO and DIZ files are simple text files, so you could simply view them in Notepad or any other simple text editor and get the info you needed. However, they were designed to be viewed with an NFO viewer. It makes them easier to read and look pretty.
There are thousands of download locations, so I won't bother to list any here. It's freeware. That means don't just double-click on everything you download hoping it will do what you want.
That's a sure-fire way to get yourself into trouble. Read the NFO files to be sure you know which files you actually need. It's also very important to use an up-to-date and competent antivirus program. This is paranoid AV programs trying to deter you from using such tools. Follow what the NFO says in those cases. Bloated messes is what they are. Remember to follow the directions in the NFO files! This is only a general guide and could be incomplete in some cases. Always remember that, like Google, backups are your friend!
