Enhanced VoIP security: What to expect in 2022

Enhanced Voip Security What To Expect In 2022

Ever since the first version of VoIP-based (Voice over Internet Protocol) phone hit the ground running in 1995, there has been a rapid development which gained frantic pace over the last five years. Pushed forward by digitization and the need to stay connected 24//7, VoIP solution providers have also evolved to serve innovative offerings in the form of instant messaging, voice and video calls, and conferencing among others. The biggest draw still, is its affordability, and the VoIP application’s framework to fuse seamlessly with new technologies.
The number of rising VoIP business solutions have also started attracting malicious actors, who try to make quick gains by tampering with the network. Consider the fact that distributed denial of service (DDoS) attacks surged 35% in the last quarter of 2021. They increased in size, quantity, and complexity making vigilance difficult. Many businesses do not have their proprietary VoIP, which leaves them susceptible to threats and looming dangers of hackers penetrating the system.

Voice Vs Data: Understanding threat parameters

For both hosted and on-site VoIP users, preventing voice network threats requires similar attention and effort as data. The device on which the call lands, either a mobile phone, VoIP phone or, business telephone system PBX (Private Branch Exchange), evaluates the request from an incoming user to accept the call or not. The entire process is based on plain text transmission taking over the open office or home network, in the absence of an encrypted connection. Nowadays, some tools also let you eavesdrop on encrypted wi-fi-based calls.
Data, on the other hand, poses different challenges than voice. The highly prevalent transnational cybercrime occurring these days is Business E-mail Compromise (BEC). Without any specialized technical skills, threat actors can impound huge losses. The US FBI’s Internet Crime Complaint Center (IC3) estimated a whopping USD 1.77 billion in losses for the year 2019 on account of business email compromise.
Depending on the industry, size, and usage, a company can seek assistance from VoIP application development services providers to understand the appropriate level of protection required. Going into 2022, companies need to beef up their VoIP security to avert threats. We bring a lowdown of security threats in the light of what can 2022 bring, read on to find out more.

Threat types and their remediation measure you should know in 2022

1.DDoS Attacks

Unarguably the most prevalent security concern among users of VoIP today. These attacks mostly affect VoIP services that use the same servers, particularly MSPs (multi-tenant service providers) and ISPs (internet service providers). In a situation when outages due to these attacks occur, the quality of service is hampered. About 44% of organizations have experienced or been targeted with ransom related attacks between August 2020 and 2021 as per Nuestar International Security Council.

Measures to ensure enhanced security:

You can take proactive steps to avoid DDoS attacks by using content delivery networks. Security solutions offered by VoIP software development organizations can detect malicious actors on the basis of algorithms that check any abnormal behavior. Some solutions have the capability to accurately detect malicious traffic on the network.

2.Packet sniffers

As the name suggests, this attack occurs during the transit of the packets. Hackers resort to sniffing logs on unencrypted networks and based on that they steal voice data packets even before they reach their destination. They can also intercept and maneuver the voice packets combining other tools. With the rising use of voice data, it is one of the most important threats to look out for in 2022. According to a study, the number of JavaScript (JS) family sniffers more than doubled. As many as 4,60,000 bank cards were compromised by JS sniffers in 2019.

Measures to ensure enhanced security:

By encrypting data end to end with a custom VoIP development service users can check packet sniffing. The other way to secure yourself is using a private VPN (virtual private network) and regularly monitoring your network.

3.Black storm attacks

Apparently, easier to launch than DDoS attacks, Black Storm Attacks can impact a service provider when hackers compromise any device connected through VoIP. It poses larger risks sometimes, as attackers can terminate the whole enterprise’s data in one instance. The manipulated IP source gets more devices to respond, and as the volume of responses increases, it chokes the service provider’s network, thus creating a Black Storm attack.

Measures to ensure enhanced security:

VoIP business solutions providers should undertake consistent vulnerability scans, install access control with router restrictions and employ machine learning-based strategies to proactively detect threats with their VoIP software development partner. The other advantage of deep learning is churning out quick insights data. Uncovering the inefficiencies accurately at the threshold level can help remediate any issues.

4.Ransomware attacks

Ransomware attacks have shot up the roof in 2021, posing a continued threat in 2022. Ransomware attacks take place by pushing in malicious software which blocks access unless a ransom is paid to free the computer or files from being held hostage. Such attacks have become more common with the amount of ransom increasing multiple times in proportion. Early in 2021, computer giant Acer received a ransom threat amounting to USD 50 million.

Measures to ensure enhanced security:

Begin by securing your end points by onboarding a VoIP solutions provider. Many ransomware actors try to get access through Remote Desktop Protocol (RDP) and the Server Message Block ports. Restricting access to these ports can be one way of abating security risks. Installing intrusion detection systems can also be useful.

As the name suggests, hackers use VoIP-based phones and impersonate them as a trusted source to extract sensitive information like passwords, debit card PIN, credit card details, and more. By a technique called caller ID spoofing, hackers try to use familiar names and numbers, already existing on your phones. The targets are timed as per the season or a particular day. A popular example is the tax season when vishing hackers make more attempts. Common ways vishing occurs are war dialing, VoIP, Caller ID spoofing.

Measures to ensure enhanced security:

Not responding to suspicious calls and allowing them to go into voicemail and at the same time registering for national do not call registry can cut down the telemarketing and vishing calls.

6.Malware and viruses

One of the biggest threats to network and security systems, malware, trojans, and viruses continue to challenge in 2022 as well. The dangerous programs provide access to the criminals into the entire system, eating up bandwidth and impacting the quality of signals. Malware and viruses on their own can do considerable damage, but they can also assist hackers to pull out important information or steal data. Eavesdropping can also be a consequence.

Measures to ensure enhanced security:

Using quality anti-virus and anti-spyware software can bring down malware and virus risks. Other ways can be secure authentication, fewer usage of admin accounts, adopting the least privilege model, applying email and spam security.


Having security over multiple layers to not only protect data on-site but remote server fortification are required in the era of hybrid work. As attacks continue into 2022, businesses must take additional steps for voice encryption and data protection. Most often, VoIP security at the periphery and level of business is better than the service provider’s stage. Securing your SIP with session control by VoIP solution providers can offer better control with an integrated network and robust server performance.

With remote and hybrid work taking a leap forward, it is necessary to fortify all devices and networks in business use. A VoIP business solution provider will help you secure your assets by going several notches over VPN-based security. When your branch and head offices operate in multiple cloud environments, your IT team will need intelligent protection to secure dynamic connectivity across multiple pathways. A holistic assessment to secure identities, avert threats and protect endpoints requires specialized skills and expertise to implement.
