python-patterns

Python implementation of patterns and offsets for fuzzing and buffer overflows.

Syntax

python3 patterns.py [Operation] [values]

Modes

Pattern Create (Mode C)

patterns creates patterns in blocks of 3 bytes, following an upper case letter, number and lower case letter pattern (A0aA0bA0c).

python3 patterns.py C 1000

Offset (Mode O)

This takes an input in 0xAABBCCDD format to look for a matching pattern in a generated pattern and it will return endian-ness and offset in bytes.

python3 patterns.py O 0x41306141

Badchars (Mode B)

This mode will generate a buffer of all hex codes followed by a buffer of 0x41 characters for a specified size, bad characters can be selected with -b 0x000102

Exploit (Mode E)

This will take shellcode from StdIn and create an output buffer of a specified size, offset, nopsled size and EIP value. It will automatically prepend append 0x41 characters to fill the specified buffer size.
