 Its main focus are ELF binaries that are commonly found on Linux and Unix operating systems. *cwe_checker* is built on top of [BAP](https://github.com/BinaryAnalysisPlatform/bap)(Binary Analysis Platform). By using BAP, we are not restricted to one low level instruction set architectures like Intel x86. BAP lifts several of them to one common intermediate represenetation (IR). cwe_checker implements its analyses on this IR. At time of writing, BAP 1.5 supports Intel x86/x64, ARM, MIPS, and PPC amongst others. Hence, this makes *cwe_checker* a valuable tool in firmware analysis.
 
 *cwe_checker* implements a modular architecture that allows to add new analyses with ease. So far the following analyses are implemented:
-- [CWE-190](https://cwe.mitre.org/data/definitions/190.html): Integer Overflow or Wraparound
-- [CWE-215](https://cwe.mitre.org/data/definitions/215.html): Information Exposure Through Debug Information 
-- [CWE-243](https://cwe.mitre.org/data/definitions/243.html): Creation of chroot Jail Without Changing Working Directory
-- [CWE-332](https://cwe.mitre.org/data/definitions/332.html): Insufficient Entropy in PRNG
-- [CWE-367](https://cwe.mitre.org/data/definitions/367.html): Time-of-check Time-of-use (TOCTOU) Race Condition
-- [CWE-426](https://cwe.mitre.org/data/definitions/426.html): Untrusted Search Path
-- [CWE-457](https://cwe.mitre.org/data/definitions/457.html): Use of Uninitialized Variable
-- [CWE-467](https://cwe.mitre.org/data/definitions/467.html): Use of sizeof() on a Pointer Type
-- [CWE-476](https://cwe.mitre.org/data/definitions/476.html): NULL Pointer Dereference
-- [CWE-676](https://cwe.mitre.org/data/definitions/676.html): Use of Potentially Dangerous Function

 Please note that some of the above analyses only are partially implemented at the moment. Furthermore, false positives are to be expected due to shortcuts and the nature of static analysis.

 ## Why use cwe_checker? ##
 The following arguments should convince you to give *cwe_checker* a try:
-- it is very easy to setup, just build the Docker container!
-- it analyzes ELF binaries of several CPU architectures including x86, ARM, MIPS, and PPC
-- it is extensible due to its plugin-based architecture
-- it is configureable, e.g. apply analyses to new APIs
-- view results annotated in IDA Pro
-- *cwe_checker* can be integrated as a plugin into [FACT](https://github.com/fkie-cad/FACT_core)

 ## How to install cwe_checker? ##
 There are three ways to install cwe_checker. The recommended way is to get cwe_checker from the Ocaml package manager Opam. You can install cwe_checker via the package [fkie-cad-cwe-checker](https://opam.ocaml.org/packages/fkie-cad-cwe-checker/) (`opam install fkie-cad-cwe-checker`).
 
 The second way is to utilize the installation script `install.sh`, which is just a wrapper around Docker. Make sure to have the latest version of Docker. 
 
 The second way is to build it using the provided `Makefile`. In this case you must ensure that all dependencies are fulfilled:
-- Ocaml 4.05.0
-- Opam 1.2.2
-- BAP 1.5 (and its dependencies)
-- yojson 1.4.1
-- alcotest 0.8.3
-- Sark for IDA Pro annotations
+-  Ocaml 4.05.0
+-  Opam 1.2.2
+-  BAP 1.5 (and its dependencies)
+-  yojson 1.4.1
+-  alcotest 0.8.3
+-  Sark for IDA Pro annotations
 Just run `make all` to compile and register the plugin with BAP.
 ## How to use cwe_checker? ##
 The usage is straight forward: adjust the `config.json` (if needed) and call BAP with *cwe_checker* as a pass.
