Fix security loopholes and defend your VoIP security

VoIP technology enables any mobile device service to operate and deliver voice communication using the internet protocol. Here, the PSTN implements voice communication over the landline telephone calls between two endpoints. Similar to other networks, voice communications are prone to VoIP security attacks. Organizations are often unaware of the security posture concerning their VoIP and PSTN infrastructure. They are not adequately able to protect from the VoIP security risks and threats that come with sensitive devices and networks.

How it works?

Methodology

Footprinting
Gather information about IP of the servers, VoIP devices, PSTN’s Signalling System with tools such as Shodan, SVmap, etc.
Enumeration
Scan and discover information about the services running in the environment.
Vulnerability Analysis
Discover the vulnerabilities in the services using tools such as Nessus, Viproy.
Exploitation
Exploit the vulnerabilities and gain leverage over the services using tools such as Metasploit.
Reporting
& Support
Prepare a comprehensive report of all the vulnerabilities which examine the strength, risk, and standards associated with the security posture of the infrastructure. Provide assistance to develop mitigation strategies based on the observations made in the assessment.

Top Vulnerabilities

Attacking VoIP authentication
Traffic capture and Eavesdropping
SBC access
Attacking SS7 components
Identifying DoS vulnerabilities
Caller ID impersonation
