VoIP companies have recently been the target of a series of ransom Distributed Denial of Service (DDoS) attacks around the globe with UK-based VoIP providers including VoIP Unlimited, and Quebec-based company VoIP.ms being hit by aggressive and sustained attacks destabilizing their infrastructure and causing massive disruption to services.
These DDoS attacks on VoIP providers have been making headlines and according to Hackread.com the attacks on VoIP.ms started on September 16th, targeting their DNS name servers and other infrastructure to disrupt their telephony services resulting in people being unable to make or receive calls. The company’s website remained difficult to access for some days after the attacks were first acknowledged.
