The cybercriminal aims to attack the public available critical infrastructure of the organization, such as VoIP telephone systems. These attacks are usually performed on the man-in-the-middle between the inbound and outbound connection of the telephone. Using such attacks, the attacker can listen to incoming or outgoing calls. The cybercriminals gain access to the internal VoIP network if network devices are vulnerable to weak passwords or using vulnerabilities.

HackiVist assesses the VoIP network penetration testing for identifying the VoIP network vulnerabilities after determining the scope of work and a detailed report prepared, which includes vulnerabilities details along with recommendations.
