VoIP Pen Testing determines the risks of attacks to these telecommunications based systems which are customarily employed in Enterprises.
In any environment around the world communication is the key. Previously whole world uses telephone networks as the mode of communication but with the advent of VoIP (Voice over IP) the mode of communication around the world has been changed.
Because of the cost effectiveness of VoIP the organizations are the first one to switch towards it. Now small businesses and household users also switched to VoIP Networks because of its cost effectiveness and good quality,
A major security threat has been created for the growing number of VoIP users around the world day by day. Any organization big or small is using VoIP as the mode of communication.
Multifaceted technology and modern day requirements increase the chance of complex assaults like call- tracking, call data manipulation, wire-tapping phone calls or even unauthorized recording of calls. Threats are posed to internal networks through VLAN because of data interchange between the client and the VoIP server.
VoIP Pen Testing determines the risks of attacks to these telecommunications based systems which are customarily employed in Enterprises.
Eavesdropping – Attackers can intercept unencrypted voice traffic and listen in on calls.
SIP Spoofing – Manipulating SIP headers to impersonate users or devices.
Denial of Service (DoS) – Overloading the system to disrupt services.
Toll Fraud – Exploiting systems to make unauthorized international or premium calls.
Man-in-the-Middle (MitM) Attacks – Intercepting and altering call data in transit.
Registration Hijacking – Taking over user accounts to reroute calls.
Weak Authentication – Using default or easily guessed credentials.
Lack of Encryption – Transmitting data without TLS/SRTP protection.
VoIP penetration testing is a structured approach to identifying and exploiting vulnerabilities in VoIP systems. It begins with information gathering to map out the VoIP infrastructure, including SIP servers, IP phones and network services. Scanning and enumeration follow, using tools like Nmap and SIPVicious to detect open ports, extensions and system versions. Vulnerability assessment identifies weak configurations, outdated software, and insecure protocols. The exploitation phase includes testing for SIP registration hijacking, toll fraud, DoS attacks and man-in-the-middle interception. This methodology ensures a comprehensive evaluation of VoIP security, helping organizations mitigate risks and strengthen their communication infrastructure against real-world threats.
