BlobPE

Description

BlobPE is a lightweight and experimental .NET (C#) library that enables standalone applications to persist structured data directly within their own executable files. By injecting a compact blob (typically JSON) into the binary, BlobPE allows applications to store and modify internal key/value data without relying on external files or configurations.

The library is intended for advanced use cases such as proof-of-concept tools, binary experiments, or environments where minimizing external traces is desired. Data is stored within the executable itself, delimited by clear markers (e.g., [BLOB_START]... [BLOB_END]), and can be read, updated, and re-injected at runtime.

Warning ⚠️: BlobPE uses a non-standard approach to binary self-modification. It is not recommended for production environments, but rather for educational, exploratory, or controlled scenarios.

Features

  • Inject structured data (JSON format) directly into the application's binary
  • Read and update key/value pairs embedded in the executable
  • Rewrite the binary to persist updated data
  • Self-relaunch after patching
  • No need for external configuration or storage files
  • Designed for use with Windows Forms.

Features in Development
Blob size limiter Automatic padding and blob size enforcement to ensure binary integrity
Binary offset alignment More robust detection and modification of embedded blobs
Obfuscation Support for basic encoding or encryption of stored data
Custom section placement Ability to store the blob in custom PE sections instead of only at the end of the file

Prerequisites

  • .NET 6.0 SDK or later
  • Windows operating system
  • Write permissions on the application’s executable file
