In the last few years, there has been a surge in DDoS attacks, specifically on VoIP providers. Several DDoS or Distributed Denial of Service attacks target communication service providers, leading to voice outages and severe impairments to organizations’ critical systems. As per a report by Atlas VPN, it has been revealed that cybercriminals committed about 5.4 million DDoS cyberattacks in the first half of 2021, which is an 11% increase as compared to the first half of 2020. Among these attacks, cybercriminals leveraged compromised computer systems and botnet networks in 2.8 million of the attacks. In this blog, you will learn about DDoS and useful tips to deal with such attacks.

A DDoS or Distributed Denial-of-Service attack is one of the most powerful weapons on the internet today that has become a great threat to several businesses. Several websites have been brought down by hackers with the help of a DDoS attack. This cyberattack aims to make a website unavailable by flooding the company’s website or service with fake requests and traffic. These overwhelming requests or traffic to a company’s website makes customers unable to access its services. 

How DDoS cyberattacks are carried out?

DDoS cyberattacks are done by overpowering the targeted websites, web servers, or networks with a lot of fake requests for connections or messages. When the targeted server attempts to fulfill all the incoming requests, it surpasses its bandwidth limit. When the bandwidth limit of a web server exceeds, it causes the server to slow down, crash, or become unavailable. 

In many cases, the targeted victims are vulnerable to a low level of DDoS cyberattack. This attack may be combined with an extortion threat of creating a more distressing attack if the company doesn’t pay a cryptocurrency sum. These attacks are sometimes done to distract the attention of the target organization. While the target company emphasizes on the attack, the cybercriminals may achieve their key motivation like installing malicious software or stealing data.

In all, DDoS attacks have been used as a weapon by profit-motivated cybercriminals and hacktivists to steal important information, disturb a company’s operations, or demand a ransom. 

How do DDoS cyberattacks affect VoIP providers?

Over a while, there has been a great increase in the DDoS cyberattacks hitting multiple Voice over Internet Protocol (VoIP) services worldwide. 

The motive of cybercriminals behind such attacks always differs. Sometimes it’s related to financial gain and sometimes it is focused on creating unnecessary chaos and disruption of services. The attackers usually steal sensitive information about the company to interrupt its daily operations or to demand a ransom amount. To cause such interruptions to the services of targeted company’s, cybercriminals generally rely on Distributed Denial of Services (DDoS) techniques. 

VoIP providers are the service providers who offer internet-based call services to different types of users and organizations such as the law enforcement departments, the police, and organizations in the public sector. With the help of DDoS techniques, cybercriminals make the target service or network inaccessible to its users by overflowing it with uninvited inbound traffic from various sources. 

Being an unprecedented attack, DDoS techniques are expected to target the weaknesses in VoIP providers to cause utmost damage to the services. Since remote working is gaining a lot of popularity especially after the pandemic, the demand for VoIP services is also rising. And cyberattacks like DDoS on VoIP services could lead to severe disruptions to internet-based communication services.

How to deal with DDoS cyberattacks?

Whether it’s a Fortune 500 company or a retailer, cybercrime is a genuine threat to your business, brand, and revenue. To ensure web and network security and ward off any cyberattacks, organizations need to implement effective DDoS protection. 

To deal with such attacks, organizations can follow certain effective measures like:

  • Organizations can leverage perimeter-level defenses, maintained and handled by an in-house team.  These can be run automatically to identify DDoS traffic and block the incoming traffic dynamically, averting the effect on core critical systems. 
  • Organizations can also get the services of significant Content Delivery Network (CDN) providers who integrate anti-DDoS technologies into their platforms. These service providers usually maintain substantial worldwide network infrastructures which can be extended in response to riveting an incoming DDoS attack.

Eventually, any approach that can help organizations to deal with the DDoS attack effectively with the same level of automated scaling proficiencies while offering a dynamic response is the need of the hour to prevent these immense network flood attacks.

Conclusion: 

With the advancement in technology, cyberattacks including DDoS attacks are also becoming more recurrent and disruptive. The VoIP providers not just deliver voice services to businesses but also provide a platform for various emergency services to manage call traffic. To ensure secure services, VoIP providers must implement all the best practices to prevent the chances of such attacks.
