SS7 MAP (pen-)testing toolkit
As a lot of people run into problems building the tool, there are binary releases which can be found here: https://github.com/ernw/ss7MAPer/tree/master/releases
As people also run into problems using the binary release, there is a docker image with ss7MAPer running on ubuntu 16.04
If you use the binary version, skip right over the next chapter.
You will need:
-
Erlang. Get it from your repo or from http://www.erlang.org.
-
Rebar. Get it from your repo or from https://github.com/rebar/rebar
-
The code (;
git clone https://github.com/ernw/ss7MAPer -
The dependencies
cd ss7MAPer rebar get-deps -
Patch the dependencies
cd deps/osmo_map patch -p1 < ../../patches/osmo_map.patch cd ../osmo_sccp patch -p1 < ../../patches/osmo_sccp.patch cd ../osmo_ss7 patch -p1 < ../../patches/osmo_ss7.patch -
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 makeCopy 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/pktAnd 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
rebar co
If all the steps above are too much to do by hand (as for me testing ;) you can use the build script here: https://github.com/ernw/ss7MAPer/blob/master/prepare_n_build.sh
The config file is split in 4 section, sctp, m3ua, sccp and target.
In the sctp section source and destination ip as well as source and destination port of the SCTP connection are configured.
In the m3ua section all the M3UA parameters, like local and remote point code are configured.
In the sccp section currently only the local (or source) global title needs to be configured.
Last but not least in the target section information about the tested environment need to be configured, like the global title of the HLR, or the MSISDN of the tested phone.
Be sure to modify it to your needs.
To run the tool one needs to start a rebar shell:
cd ss7MAPer
rebar shell
Start the application and its dependencies with:
application:start(sasl).
application:start(ss7MAPer).
If everything is set up correctly the m3ua connection comes up.
Run the application by starting it from the root directory:
cd ss7MAPer
./bin/ss7MAPer console
If everything is set up correctly the m3ua connection comes up.
Once the application is started, there are some commands that can be executed from the erlang command line:
- ss7MAPer:test_hlr()
- ss7MAPer:test_msc()
- ss7MAPer:test_smsc()
and each of them does exactly as its called, running MAP tests against the targets defined in the config file.
