We saw an immediate drop in fraudulent traffic when we implemented the automatic system onto our network .
COVER STORY
Arnd Baranowski , CEO of Oculeus
How has the Oculeus solution helped SFR tackle fraud ?
Thanks to the Oculeus tool , so far we have been able to lower the amount of fraud by 50 %. We did a calculation at the end of last year and when we compared 2017 and 2016 , we had 53 % less fraud thanks to Oculeus ’ automatic fraud detection and blocking tools .
So would you say you ’ ve found the solution beneficial for SFR ?
Yes , I consider it very beneficial and it is a very productive tool .
When the system discovers fraud , what does it do to block it ?
When we discover fraud , we kill the traffic because in general it occurs at night or during the weekend so there is an automatic blocking of the fraudulent traffic . Then we carry out some analysis to find out the origin of the fraud and sometimes we also have a discussion with the suppliers to inform them of the fraudulent traffic that we have revealed .
Is the solution quick and has this been beneficial for SFR ?
The solution had a very quick effect and we saw an immediate drop in fraudulent traffic when we implemented the automatic system onto our network . The solution did not take several months to see the impact , rather it was immediate .
What are the other advantages of the system ?
First of all , you reduce the fraud attacks , so of course it is an advantage in terms of these reductions . We don ’ t know who is offering this money behind these fraud attacks , some people are using cash for maybe ransom or other criminal acts .
The solution is described as being able to identify and fight nearly every type of fraud within minutes . Could you expand on this ?
I can give you an example of traffic to several destinations but we can ’ t detect fraud traffic coming from customers going to expensive destinations . We know that this traffic is perhaps not going to this destination , but to the fraud equipment and there is a flow of cash afterwards following this flow of traffic . There are some countries using termination of traffic so in this case , it is huge volumes generated from fake customers on the corporate side and there is also fraud traffic coming from wholesale .
This means that this traffic is coming from our customers which are advert operators . For example , a large Tier 1 operator could be hacked or generating some fraudulent traffic which it hasn ’ t detected and it is part of our responsibility to warn it of this as we sometimes receive some traffic when

using the automatic tools . We avoid having to discuss fraud too much with our customers .
What are the hackers interested in gaining from the fraudulent attacks to the system ?
The objective of the hacker is to find a way to go into the system , so in general they are using a corporate switch to generate lots of traffic without paying for it at the beginning .
You have people involved in this fraud at the beginning and at the end , so at the beginning they generate traffic without paying for it and at the end they receive this cash because it is very hard for the operators to detect this transmission . u www . intelligentciso . com | Issue 02
