msfpatterns
msfpatterns (Buffer Overflow Finder) is a tool for generating and analyzing cyclic patterns, similar to pattern_create and pattern_offset from Metasploit. It helps exploit developers identify exact buffer overflow offsets across multiple architectures, including 16-bit, 32-bit, and 64-bit platforms.
Features
- Generate unique cyclic patterns for buffer overflow analysis
- Find offsets of overwritten return addresses in memory dumps
- Supports 2-byte, 4-byte, and 8-byte searches (suitable for MSP430, x86, x86-64, etc.)
- Returns all matching offsets (useful for 16-bit systems where repeats may occur)
- Simple CLI interface
Installation
Using uv (recommended)
uv tool install msfpatterns
Using pip
pip install msfpatterns
CLI Usage
Generating a Pattern
pattern 128 # Generates a pattern of length 128
Finding an Offset
pattern -q 0x41306241 128 # Find offset of 0x41306241 in a 128-byte pattern
Library Usage
You can also use msfpatterns as a Python library:
from msfpatterns import generate_pattern, find_offset
pattern = generate_pattern(128)
print(pattern)
offset = find_offset("0x41306241", 128)
print(f"Offset: {offset}")
