Process Memory Scanner

Fast pattern scanning for Linux processes with wildcard support.

Features

• Read executable regions (r-xp) and scan for byte patterns.
• Wildcards (??) in patterns for build-to-build stability.
• Efficient chunked scanning to reduce memory usage.
• Example test target with build-dependent bytes.

Requirements

• Linux
• gcc or compatible C compiler
• Permission to read target process memory (ptrace_scope may apply)

Build

make

This produces process_memory_scanner.

Usage

./process_memory_scanner [-v] [-p pattern_file] <process_name>

• -p: pattern file path (default: pattern.txt)
• -v: verbose region scanning logs

Example:

./process_memory_scanner -v -p pattern.txt mygame

Pattern format

pattern.txt example:

Pattern: 488d05????????4889c7b800000000

• Each pair of hex digits is a byte.
• ?? matches any byte.
• Spaces are allowed.

Notes

• Scanning other processes may require elevated permissions.
• Use least privilege and only scan authorized processes.
