Memory Viewer: A Lightweight Tool for Hex & Structure Analysis

Overview

Memory Viewer is a compact utility designed to let developers, reverse engineers, and forensic analysts inspect process memory as raw hex and as interpreted structures. It focuses on speed, low resource use, and clarity — showing bytes, offsets, ASCII interpretation, and configurable structure layouts side-by-side for rapid analysis.

Key Features

• Hex dump with offsets: byte-level view with configurable word widths (8/16/32/64-bit) and base display (hex, decimal).
• ASCII/UTF-8 rendering: printable characters shown alongside hex; non-printables rendered as dots or escape codes.
• Structure interpretation: define structs (types, sizes, endianness) and map them onto memory to see field values in-context.
• Search & navigation: fast pattern and string search, jump-to-offset, and bookmarking.
• Live process attachment: optional read-only attach to local processes or load memory dumps.
• Annotations & notes: tag offsets and fields with comments for later reference.
• Exporting: save hex ranges, structure interpretations, or annotated reports.

Typical Use Cases

• Rapidly inspecting a program’s memory for strings, pointers, or signatures.
• Verifying in-memory structures when debugging serialization issues.
• Supporting malware or incident analysis by revealing in-memory artifacts.
• Teaching low-level data layout and endianness in systems courses.

How It Works (Workflow)

1. Load memory source: live process (read-only) or memory dump file.
2. Configure view: select base address, bytes per row, endianness, and word width.
3. Define or load structure templates (C-like or JSON) that describe fields and types.
4. Map a template to an address range; fields render with interpreted values next to raw bytes.
5. Search for patterns or strings, add bookmarks/notes, then export findings.

Structure Definition Example

Use a simple C-like struct to interpret data:

c
Copy CodeCopied
struct User {
uint32_t id;
  uint16_t flags;
  uint16_t name_len;
  char name[name_len]; // variable-length
};

The Memory Viewer resolves fixed fields first, then shows the inferred name slice as ASCII next to the hex.

Tips for Effective Analysis

• Start with small regions around pointers or discovered strings to limit noise.
• Use little/big-endian toggles when values look wrong.
• Save commonly used structure templates for repetitive tasks.
• Combine pattern searches with structure mapping to locate scattered records.

Performance & Safety

Memory Viewer operates read-only for live attachments to avoid modifying target processes. Lightweight parsing and lazy loading of file-backed dumps keep memory and CPU usage low while allowing large-address-space navigation.

Export & Reporting

Generate concise reports containing:

• Hex excerpts with annotated fields
• Resolved field values and offsets
• Bookmarks and investigator notes

Reports export to plain text, JSON, or HTML for sharing or archival.

Limitations

• Not a full debugger — no write or execution control.
• Complex dynamic data (deep pointers, in-memory compression) may require manual interpretation.
• Live process attachment may be restricted by OS permissions.

Conclusion

Memory Viewer strikes a balance between simplicity and power: a fast, readable hex inspector with structured interpretation capabilities that speed debugging and forensic tasks without the overhead of heavyweight toolchains.
