With more organizations turning to VoIP (Voice over Internet Protocol) and cloud-based Unified Communications (UC) systems to underpin their commercial services and corporate communications, IT response and security testing teams are struggling to keep pace with the VoIP attack surface and growing number of threats in the wild, according to Fatih Ozavci from Context Information Security, speaking at the Black Hat USA 2016 on Thursday.
“A lack of understanding of modern VoIP and UC security, means that many service providers and businesses are leaving themselves at risk to threat actors repurposing this exposed infrastructure for attacks such as botnets, malware distribution, vishing, DoS and toll fraud,” says Ozavci.
