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 ,

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.…

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.

SIPVicious PRO 6.0.0-beta.4 getting close to take-off!

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.…
