As some of you know, I was speaking at the Digium Asterisk World event, that took place in Miami a couple of weeks ago – as part of the ITexpo show (http://www.tmcnet.com/voip/conference/digium-asterisk-world/default.htm). During my presentation, I had showed the following slide:

Well, apparently, I was slightly wrong – well, not all the way wrong. While the general term is that fraudsters don’t publish their success on the Internet, it would appear that we are now at the verge of seeing “Fraud Enabling Services”.

Everybody is talking about BIG DATA. Since the proliferation of data accumulation during the past few years, almost any business is confronted with the BIG DATA question. While Google, Facebook, Twitter, FourSquare and such are more than able to utilize this trend, how can other companies benefit from the BIG DATA advantage?

International roaming services had been around since the early beginnings of mobile networks, well, not all that early – but still fairly early. Most people believe that international roaming relies on your phone number, but actually, it involves the usage of something called an MSRN – A Mobile Station Roaming Number.

First of all, before I go on and add additional information on the previous post – I’d like to do one thing – sound the ALL CLEAR alarm signal. It would appear that while the Humbug engine had identified an anomaly, it had identified something that was out there for some time now, was catered by Asterisk internally – however, we didn’t have a clear indication of what it looks like as the attack is going on. And now, with a bit more details.

The amount of data collected by the Humbug platform is sometimes mind boggling. With over 5000 connected PBX systems and over 4 million events on a daily basis – the amount of information stored can be overwhelming at start. As with any type of system that collects information at such rates, you sometimes need to step back and look at the data from a fresh point of view – and at some brief moments of clarity, a new pattern emerges and sheds new light on your accumulated data.

The data being analyzed and aggregated by the Humbug engine is very interesting. While the various usage patterns and call patterns being analyzed are fairly common and identical around the world (bearing in mind the various locations), we like analyzing our black lists – specifically those that include verified fraud destinations.

According to the above, Telephony Fraud can be described as combination between cases 2 and 3 of the theory. Primarily due to the following:
We can’t predict or calculate when our PBX system will be hit by a fraud attack
When we are attacked – usually the ramifications are profound, specifically we maintain a high volume system
When it comes to handling it – we usually put our heads into the sand, negating the problem as the carriers problem

Well, the past month had been as hectic as can be, specifically with us hard at work re-working parts of the UI and preparing our alert services. As you may have noticed, the SaaS version had been changed from 0.3 (Falcon) to 0.4 (OSPREY). Version 0.4 brings a slightly slicker look, that makes the usage a bit more stream lined.

Well, if you tried logging into your account today, you may have been greeted by a fairly short message saying that we are currently undergoing some upgrades. Well, in general, the reason for this upgrade is good, we’re upgrading simply because we need more capacity. The only annoying part is that the upgrade is taking just a bit longer than we anticipated.
