LLT

Low-level toolkit

Introduction

A gathering of tiny scripts (mostly one-liners) that can help in low-level developmet and shellcoding.

Useful for hex/bytestream conversions, NASM compilation and instructions analysis.

The output of every script can be piped, except for nasm32/64 that simply drops a compiled binary in current dir.

Scripts

• bin2hex - converts raw binary file to a hexpair stream

• cmd2hex - constructs a base64 command executor and converts it to hex

• nulls - shows all instructions from object file that contain nullbytes

• rdlf - readelf pretty-printer

• binsrv - serves single or multiple binaries on random port and returns the port number

• v4hex - converts an IPv4 address to hex (prefixed with '0x')

• v6hex - converts an IPv6 address to hex (prefixed with '0x')

• nasm64 - compiles NASM source to 64 bit ELF

• nasm32 - compiles NASM source to 32 bit ELF

• txt - extracts raw .text section from executable

• push - creates an assembly push sequence that places a desired string on stack

• More coming soon...
