About Ivan Nyarko (Kwancro)

helping SIP security by providing free honeypot data

With the help of honeypots, I am gathering and analysing SIP data. You can read about how it all started in my blog post 'Understanding Voip Hackers'. Hourly statistics can be seen here. All data is shared with the hugely popular and free service APIBAN to help block bad SIP traffic.

All support is deeply appreciated!

Interesting findings:

Open relay abuse

Massive attacks through VPN
