This project is born with the aim to develop a lightweight, but useful tool. The reason is that the existing hex editors have some different limitations (e.g. too many dependencies, missing hex coloring features, etc.).

This project is based on qhexedit2, capstone and keystone engines. New features could be added in the future, PRs are welcomed.

Features

Chunks loader - Used to load only a portion of large files without exhaust the memory (use alt + left/right arrows to move among chunks). Please note that in chunk mode, all the operations (e.g. search) applies only to the current chunk except for file save (the entire file is saved). However, each time you edit a chunk, save it before to move to another chunk, otherwise you will lose your changes.
Search and replace (UTF-8, HEX, regex, reverse search supported) [CTRL + F]
Colored output (white spaces, ASCII characters, 0xFF, UTF-8 and NULL bytes have different colors)
Interpret selected bytes as integer, long, unsigned long [CTRL + B]
Copy & Paste [CTRL + C and CTRL + V]
Copy selected unicode characters [CTRL + Space]
Zeroing all the selected bytes [Delete or CTRL + D]
Undo & Redo [CTRL + Z and CTRL + Y]
Drag & Drop (Hint: Drag&Drop two files to diff them)
Overwrite the same file or create a new one [CTRL + S]
Goto offset [CTRL + G]
Insert mode supported in order to insert new bytes instead to overwrite the existing one [INS]
Create new instances [CTRL + N]
Basic text viewer for the selected text [CTRL + T]
Reload the current file [F5]
Compare two different files at byte level
Browsable Binary Chart (see later for details) [F1]
Hex - Dec number converter [F2]
Hex String escaper (e.g from 010203 to \x01\x02\x03) [F3]
Pattern Matching Engine (see later for details)
Disassebler based on Capstone Engine [F4]
Assembler based on Keystone Engine [F4]
Zoom-Out/Zoom-In bytes view (CTRL + Up/Down or CTRL + -/+)
Shortcuts for all these features

Pattern Matching Engine

Fhex can load at startup a configuration file (from ~/fhex/config.json) in JSON format with a list of strings or bytes to highlight and a comment/label to add close to the matches.

Examples:

{
    "PatternMatching":
    [
        {
            "string" : "://www.",
            "color" : "rgba(250,200,200,50)",
            "message" : "Found url"
        },
        {
            "bytes" : "414243",
            "color" : "rgba(250,200,200,50)",
            "message" : "Found ABC"
        }
    ]
}

To activate pattern matching press CTRL + P At the end, Fhex will show also an offset list with all the result references. Note: Labels with comments are added only if the window is maximized, if labels are not displayed correctly please try to run pattern matching again.

Binary Chart

Fhex has the feature to chart the loaded binary file (Note: In order to compile the project, now you need also qt5-charts installed on the system). The y-axis range is between 0 and 255 (in hex 0x0 and 0xff, i.e. the byte values). The x-axis range is between 0 and the filesize.

The chart plots the byte values of the binary file and let you focus only on the relevant sections. For example, if in a binary file there is an area full of null bytes, you can easily detect it from the chart.

What is Bug Bounty ?

A bug bounty program, also called a vulnerability rewards program (VRP), is a crowdsourcing initiative that rewards individuals for discovering and reporting software bugs. Bug bounty programs are often initiated to supplement internal code audits and penetration tests as part of an organization's vulnerability management strategy.

Many software vendors and websites run bug bounty programs, paying out cash rewards to software security researchers and white hat hackers who report software vulnerabilities that have the potential to be exploited. Bug reports must document enough information for for the organization offering the bounty to be able to reproduce the vulnerability. Typically, payment amounts are commensurate with the size of the organization, the difficulty in hacking the system and how much impact on users a bug might have.

Mozilla paid out a $3,000 flat rate bounty for bugs that fit its criteria, while Facebook has given out as much as $20,000 for a single bug report. Google paid Chrome operating system bug reporters a combined $700,000 in 2012 and Microsoft paid UK researcher James Forshaw $100,000 for an attack vulnerability in Windows 8.1. In 2016, Apple announced rewards that max out at $200,000 for a flaw in the iOS secure boot firmware components and up to $50,000 for execution of arbitrary code with kernel privileges or unauthorized iCloud access.

While the use of ethical hackers to find bugs can be very effective, such programs can also be controversial. To limit potential risk, some organizations are offering closed bug bounty programs that require an invitation. Apple, for example, has limited bug bounty participation to few dozen researchers.
