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. If you know similar software or want to share links to other useful tools, please do so in the comments! Click here to cancel reply.
Name required. Email will not be published required. The process is a little different depending on which disassembler you're using. This will show you what DLL files are being loaded by the program. Use the debugger to examine which functions are being called from the DLL. Find the counter function. Many programs use a timer for copy protection, and when the timer runs out, the user is no longer able to access the program. The goal is to find this counter code, and then bypass it.
If the program you are cracking uses a different form of protection, you will need to look for that instead. Once you've isolated the counter function, set your disassembler to break when it is encountered. This will allow you to look at the exact code that is occurring when the counter function is called.
Now that you've found the code for the counter function, you can change the code so that the counter never reaches the point where it shuts you out of the program.
For example, you could make it so that the counter cannot count up to the break limit or you can bypass the counter by jumping over it. Recompile your newly-cracked software. After disassembling and editing, you'll need to compile the new version of the program so your changes propagate to the DLL files and other dependencies. Theoretically, any activation can be bypassed. If you know assembly, I suggest you search for an input value being compared against a complex algorithm and bypass that block of code.
Not Helpful 9 Helpful Tutorialspoint has assembly programming in it. It has a link to Coding Ground which has an assembly IDE on it so you can practice assembly without installing software on your computer. It's a great site, but you can utilize the internet too! Look up tutorials to help you learn.
