πŸ¦‘WHY REVERSE ENGINEERING ?
#Basic

> To disassemble a program, someone doing reverse engineering on software can use several tools. One instrument is a hexadecimal dumper that prints or shows a program's binary numbers in hexadecimal format (which is easier to read than a binary format).

> The reverse engineer will classify some parts of a program and see how they operate by understanding the bit patterns that represent the processor instructions as well as the instruction lengths. The disassembler is another popular method. The disassembler reads the binary code and then reveals the text form of each executable command.

> A disassembler can not say the difference between an executable instruction and the program's code, so a debugger is used to keep the disassembler from disassembling the program's data parts. A cracker may use these techniques to change code to gain access to a computer system or inflict other harm.

> Reverse engineering of electronics means pulling a system apart to see if it functions. For example, if a maker of processors needs to see how the processor of a competitor operates, they might buy the processor of a competitor, disassemble it, and then make a processor close to it. In certain nations, however, this method is unconstitutional. In general, reverse engineering of hardware involves a great deal of experience and is very costly.

SS7 TOOL

1) git clone https://github.com/ernw/ss7MAPer
The dependencies

2) cd ss7MAPer
rebar get-deps
Patch the dependencies

3) cd deps/osmo_map
patch -p1 < ../../patches/osmo_map.patch

4) cd ../osmo_sccp
patch -p1 < ../../patches/osmo_sccp.patch

cd ../osmo_ss7
patch -p1 < ../../patches/osmo_ss7.patch

5) Get the deps to build (; This is not as easy as it might sound, I needed to:
Patch the epacp/rebar.config and replace

{port_envs, [
{"DRV_CFLAGS", "-g -Wall $ERL_CFLAGS"},
{"DRV_LDFLAGS", "-lpcap $ERL_LDFLAGS"}
]}.
with

{port_envs, [
{"CFLAGS", "-g -Wall $ERL_CFLAGS"},
{"LDFLAGS", "-lpcap $ERL_LDFLAGS"}
]}.
Another dependency is not covered by rebar, so you need to fetch it manually:

cd deps
git clone http://cgit.osmocom.org/erlang/signerl/
Build the ASN.1 source files:

cd deps/signerl/TCAP/asn_src/ITU
make
Copy the ASN.1 files to osmo_sccp:

cp deps/signerl/TCAP/asn_src/ITU/*rl deps/osmo_sccp/src/
Also the osmo libs have dependencies on each other and some other deps are shared, so I created some symlinks:

mkdir deps/epcap/deps
ln -sd ../../pkt deps/epcap/deps/pkt
mkdir deps/osmo_sccp/deps
ln -sd ../../osmo_ss7 deps/osmo_sccp/deps/osmo_ss7
ln -sd ../../epcap deps/osmo_sccp/deps/epcap
ln -sd ../../pkt deps/osmo_sccp/deps/pkt
ln -sd ../../signerl/MAP deps/osmo_sccp/deps/MAP
ln -sd ../../signerl/SCCP deps/osmo_sccp/deps/SCCP
ln -sd ../../signerl/TCAP deps/osmo_sccp/deps/TCAP
mkdir deps/osmo_map/deps
ln -sd ../../osmo_ss7 deps/osmo_map/deps/osmo_ss7
ln -sd ../../epcap deps/osmo_map/deps/epcap
ln -sd ../../pkt deps/osmo_map/deps/pkt
And copy some files in place:

cp deps/signerl/SCCP/itu/include/sccp.hrl deps/osmo_sccp/src/
cp deps/signerl/TCAP/include/tcap.hrl deps/osmo_map/src/
Build the code

MacOS Apps Hacks:

This is a shared libraries that spoofs some ObjC method calls.

Make sure to disable SIP (csrutil disable from Recovery) :

1) git clone https://github.com/gebeto/macos-hacks

2) cd macos-hacks

3) cd <APPLICATION>

4) make

5) You can use run.sh, it's a wrapper script that sets necessary environment variables to insert the lib and launches Applications (it assumes that installed to /Applications, edit the script if it differs for you).
