We just made two builds available to our SIPVicious PRO members. One is called the stable build, while the other is the experimental build. The v6.0.0-beta.5 stable build includes a large number of fixes, much better (or sane) defaults and full coverage of SRTP throughout the toolset. The experimental version is where the excitement is. Our members now have access to 5 new tools that we find useful in our work:…

Why volumetric DDoS cripples VoIP providers and what we see during pentesting
Published on Oct 13, 2021 in denial of service, voip security
An epiphany Until a few days ago, I was of the opinion that simulating volumetric DDoS attacks is not something we should be doing. If you had asked us for such a test, we would have given you a negative answer. Ironically, we had been unwittingly simulating volumetric DDoS attacks while quietly ignoring our own results. But, it’s time to stop neglecting bandwidth saturation and start giving it the attention that it deserves.…

Published on Sep 24, 2021 in denial of service, voip security
VoIP.ms and other VoIP providers under DDoS attack At the time of writing, a major VoIP provider called VoIP.ms is under a distributed denial of service (DDoS) attack since over a week. As a result, they are unable to serve their customers with everyone and their dog complaining that they cannot connect to VoIP.ms’s SIP servers as well as other resources. At the same time, someone claiming to be part of the REvil ransomware group is blackmailing the provider.…

SIPVicious PRO 6.0.0-beta.4 getting close to take-off!
Published on May 20, 2021 in sip security, sipvicious pro, sip security testing, sipvicious releases
This one’s a bit of a boring update for SIPVicious PRO. That’s because we’re getting to a stable place where flag names and values do not change too often. Which means, we’re getting out of beta rather soon! However, it is still a major update because we made a significant number of internal changes. For example, we standardized a number of flags to be the same across all tools. We discovered that we can minimize each tool’s flagset by making use of config flags such as --auth-config that allows you to configure behaviours specific to how SIPVicious handles authentication (e.…

OpenSIPIt'01: Lessons learned, STIR/SHAKEN security testing and RFC 8760
Published on Apr 16, 2021
Executive summary (TL;DR) It was a great event, highly recommended if you’re a SIP developer. We developed new STIR/SHAKEN capabilities in SIPVicious PRO. And we found some vulnerabilities during the event that got fixed in the process. What was OpenSIPIt#01 about? This week the humble security researchers from Enable Security participated in OpenSIPIt#01, an online event run by the community to test interoperability across various independent open-source SIP implementations especially when it comes to new RFCs.…
