Voice over internet protocol is a communication methodology that has revolutionized the telephony industry gaining acceptance and embrace from different quarters.

The rapid deployment of VoIP can be attributed to two major factors; its cost-saving nature and efficiency.

It is projected that the number of people using VoIP communication will reach 140 billion by the year 2024.

Many telecommunication service providers are rapidly integrating VoIP into their systems and availing the same to their customer base.

Longer stride towards the achievement of efficient and affordable communication has been achieved courtesy of VoIP.

However, challenges and derailments especially security concerns continue to frustrate these efforts.

Unemployment and loss of molarity fabric have led to a tremendous increase in malicious activities worldwide some of which halt the development of our economies.

The information, communication and technology sector is adversely affected, and cyber insecurity is now a global concern.

In 2017 alone the US reported seven serious cyber-attacks that nearly brought many businesses down to knees.

VoIP is not spared either, and risk of information leakage to un-desired spheres and system attacks are some of the areas that should be leveraged to assure users of a perfect telephony system.

VoIP attacks are now a worry to any company using the VoIP communication system.

Nettitude report of 2015 depicts VoIP attacks to account for 67% of server failures in the UK.

What is VoIP attack? Just as the VoIP system is uniquely designed to ensure seamless communication, the challenges are unique and complicated.

VoIP attack is now a common phenomenon in many organizations.

It is virtually any activity that is targeted at halting the operation and services of a Voice over Internet Protocol.

VoIP threats are classified into five categories by the Voice over Internet Protocol security alliance (VoIPSA), this include:

Eavesdropping

Malicious users gain access to communication between two endpoint VoIP and monitor conversations, and this is quite risky as they can reconstitute conversation and misinform one party, harvest numbers as well as capture call traffics.

Such activities will hinder communication and compromise productivity.

Third party accesses to conversations gives liberty to an analysis of discourse offline.

Eavesdropping is a fairly common occurrence, and hackers evolve techniques used in the capture of information.

Some of the widely used techniques include; VOMIT, SIPtap, and Peskyspy.

Using SIP identify information on the network, the hacker could move laterally within a VoIP system to compromise any phone at your company.

Interception and manipulation of calls

In this form of VoIP attack, unproven and wicked users have full control of your communications.

They hold you hostage by tapping your calls, redirecting to unintended destinations and even stopping calls.

It is sometimes challenging to identify such anomalies in your conversation.

Impersonation and false representation are a critical motive of such ill doings.

Hijackers are currently using these techniques to extort targeted people.

Social threats

Social threats involve uncalled for misrepresentation of social identity, legal users, authority, and information.

Such moves are meant to taint the image of an organization and have extensively affected the reputation of some well-established organizations.

Blackmail is also used by attackers to acquire funds from companies fraudulentl

Abuse of service

Service abuse is an enormous threat to the harmony of VoIP and is getting prevalent every day.

People in a bid to fulfill their curiosity will engage in some offensive activities that in the long run prove destructive to businesses.

Interruption of services

Whether intentional or unintentional, activities aimed at hindering communication in a VoIP system are a worrisome occurrence which is on the rise.

Physical threats for instance power loss or power surge are also a cause of VoIP attack.

In securing communication, a look at PBX is essential as a viable alternative.

However, things are not any better as the hackers never spare PBX as well.

So what is PBX hacking? It is a type of communication fraud whereby hackers infiltrate into telephone systems to listen to conversations and even make long distance international calls without one’s consent, this way, they collect revenue and sustain their unacceptable activities.

Generally, PBX web interface vulnerability predisposes users to such attacks, the simplest way to combat such insecurity is to block any outside traffic from getting to them (or disable them entirely if necessary).

Whether that’s through interface binding or firewall/ACL is up to you.

This way, you will achieve protection against criminals milking money from businesses.

VoIP is proven as a better avenue.

The question is; can VoIP be hacked? Yes! Hackers burn the midnight oil to find new ways and techniques to frustrate every noble initiative.

Standard methods used by hackers to attack VoIP are SIP scanning, phone vulnerability, signaling attack among others.

What is SIP attack? Session initiation protocol (SIP) attacks also known as Invite of Death attack occurs when there is an exchange of malformed or somewhat malicious information in the telephony network due to unwarranted entries.

SIP scanner is comprised in these situations.

What is a SIP scanner? It is one of the four tools crucial to the operation of VoIP.

It allows for authentication of devices and conversations.

Defects in SIP scanner will predispose to SIP attacks.

An understanding of how to hack VoIP servers and to put in place measures to prevent these is important.

Besides, knowledge of VoIP hacking tools is vital for both hackers and data expertise to restore functions.

SIPVicious SIP Scanner is a suite of tools that can be used to audit SIP based VoIP systems.

Do you have your VoIP phone system hacked? Worry not, expertise solutions can restore your communication, but you can instead opt for less costly preventive measures such as a proper configuration of protection, call controls within your organization and creating an effective response strategy.

It is a fact that downtimes related to communication system hacking are responsible for considerable losses in very many entities.

A clear understanding of hacking operations and mounting sufficient protective mechanisms will most likely ensure you are safe.

Let us overcome the downsides of technology and exploit it for the betterment of our society.
