Summary¶

Trying to come up with a fuzzing interface.

Participants¶

• André Boddenberg (email: dr.blobb@gmail.com)

Details¶

First setting up the femtocell and understand basics of UMTS communication.
Collecting information e.g. slides, talks, docu about fuzzing of wireless protocols.
Writing some code to craft requests and run fuzz tests against subscriber.

Note: first time fuzzing.

Journal¶

2017-03-07
pick up package at the sysmocom office.
having an informative conversation with Neels about jenkins.osmocom.

2017-03-12
Set up wiki page.
Seeing femtocell on network interface and knocking ports:

22/tcp open ssh
8089/tcp open http
8090/tcp open telnet
10002/tcp open documentum (needs investigation)

Compiled source as described, but couldn't configure/launch CN successfully (yet).
Next time trying Neels' launch script and same IP range.

Note: Feeling the need for an additional LAN port to not interfere with eth0.

2017-03-15
Reading data sheet [overview] data sheet [details] about ip.access nano3G S8.
Configuring femtocell via telnet (dry run).
Running in HLR issue mentioned in wiki when invoking run.sh.

Conclusions¶

- additional LAN port dedicated for femtocell is great.
- network LED does not indicate whether IP has been assigned by DHCP server.
