Some editors distinguish themselves at helping the user derive meaning from the examined file, extracting ASCII and Unicode contents, searching for patterns, recognizing common structures, and so on. There are lots of hex editors out there; I want to mention a few that I find particularly useful for analyzing malware and examining malicious document files.

As expected, it can perform standard hex editor duties, such as viewing and editing file contents in a hex form, but it also does more than that. Furthermore, the tool has a built-in x86 disassembler: simply point the cursor at the area of the file you want to treat as code, and the tools will show you the corresponding assembly instructions. The disassembler is especially helpful when looking at shellcode embedded in malicious files. FileInsight includes numerous other analyst-friendly features, such as the ability to import data structure declarations, HTML syntax highlighting, and tools for decoding various data obfuscation methods xor, add, shift, Base64, etc.

FileInsight also allows you to automate actions using JavaScript and Python. The tool's biggest weakness is, perhaps, its inability to open very large files. For instance, when attempting to load a MB file, FileInsight produced a "Failed to open document" error.

Malware Analysis - What is a Scantime Crypter?

Its freeware version provides typical hex editor features in a friendly and highly-customizable interface, but is not particularly impressive. The features of Hex Editor Neo relevant to malware analysis are present in its commercial versions see version comparison. For instance, the Standard version introduces the support for handling data manipulations, such as decoding, encrypting and deobfuscating using common algorithms.

Notably, these features are included for free in FileInsight. The Professional version introduces support for viewing and editing local resources, such as NTFS streams, local disks, process memory and physical RAM.

The Ultimate version includes scripting support and built-in disassemblers for x86, x64 and. NET code. FileInsight is probably a better match than Hex Editor Neo for regular malware analysis use. However, Hex Editor Neo's commercial versions add value to the toolkit by supporting very large files, x64 and.

NET disassembly, local resource editing, searching for Unicode strings and extensive customization support of its user interface. FlexHex is a powerful commercial hex editor from Heaventools Software that includes many features comparable to commercial versions of Hex Editor Neo, though FlexHex does not support scripting. However, FlexHex might get confused when attempting to parse some malicious OLE files, presenting a "The docfile has been corrupted" error. Overall, this is probably the weakest editor of those examined here from the perspective of a malware analyst.

Its core features are comparable to those of the commercial versions of Hex Editor Neo and FileHex: support for very large files, data manipulation, local resource editing, and so on.

Like Hex Editor Neo, Editor also supports scripting. This makes it easier for the analyst to navigate various file formats, including Windows executables PE filesWindows shortcut LNK files, Zip archives, Java Class files, and many more.

It supports macros, scripts and even has an API set for additional extension and automation. It works in a DOS-style console window and is generally unfriendly towards a new user, in comparison to the other hex editors I discussed so far.

Convert is operating correctly. This gives you the decimal value of the hex number. Now to get it back out as a hex number you can do this:. You can still XOR it with another number. The base a number is represented in doesn't matter. The number 15 base 10 decimal and the number 0xF in hex are the same number. Just using different bases to represent them.
