Voice over IP (VoIP) infrastructure has become more susceptible to cyber attacks in recent years due to the proliferation of both its use and the tools that can be used for malicious purposes. During the first quarter of 2015, our security researchers have observed a large amount of VoIP attacks worldwide; however, the majority were against UK servers.
Our researchers found that VoIP attacks often started just a few minutes after a new server went live. Worryingly, they also identified that 88 percent of VoIP attacks took place outside of regular working hours, when there would typically be no security staff present to monitor the situation.
Nettitude has released the findings of this research in full, detailing the key findings and explaining the tools and techniques that are being used by today’s VoIP attackers.
