DDoS Attacks

A DDoS Attack is an attempt to make a Web Server or Website unavailable or to go down by overwhelming it with traffic from numerous sources. The attacks will target a broad range of websites from banks and news sites and target small businesses, individual websites, political platforms. No Website or Web Server is immune to DDoS Attacks.

DDoS attacks can have a damaging consequence on a businesses bottom line, both with mitigation costs and lost revenue. The attacks result in lasting damage to the reputation of a company and could hurt customer loyalty.

How DDoS Attacks Happen

Attackers create a network of infected machines called botnets. This is done by spreading malicious software through Websites, Social Media, and even emails. They can then manipulate these machines without your knowledge or consent and even use these machines as an army to launch an attack against the targeted Website or Web Server. Some botnets can be hundreds or thousands of computers linked in an attack. An unprotected website stands almost no chance.

Botnets can produce massive floods of traffic to overwhelm a Server. The floods can be produced in a large range of different ways, which can include sending vast amounts of random data to consume the target's bandwidth.

Unfortunately, almost anyone can get their hands on DDoS For Hire Services through underground markets to disrupt a company’s online operations.

The Impact of DDoS Attacks

When a website or online service is inundated with malicious traffic (DDOS attacks), it can experience significant disruption, leading to loss of availability and severe consequences for business operations. This disruption often results in immediate financial losses due to interrupted services or sales, and can cause long-term reputational damage as users and customers lose trust in the affected entity's reliability. Additionally, the financial burden of mitigating the attack and recovering systems can be substantial, encompassing costs for technical resources, legal fees, and compliance-related expenses. In extreme cases, persistent DDoS attacks can lead to regulatory penalties if they breach service level agreements or industry regulations, compounding the overall impact on the organization's financial health and public image.
The consequences of a successful DDoS attack can be severe, including:

• • Service Downtime: Website or service unavailability can lead to loss of revenue, productivity, and customer trust.
• • Reputation Damage: Frequent or prolonged downtime can tarnish a brand’s reputation and erode customer confidence.
• • Increased Costs: Mitigating attacks and recovering from their impact often involves significant financial and operational costs.
• • Legal and Compliance Issues: For businesses, downtime can lead to legal ramifications, particularly if it breaches service level agreements (SLAs) or compliance regulations.

How to Identify a DDoS Attack

The most common symptom of a DDoS attack is when a website, Server, or services suddenly becoming slow or unavailable.

Keep in mind that a number of causes, such a legitimate spike in traffic, can create similar performance issues. Traffic analytics tools can help you spot some signs of a DDoS attack.

• • Suspicious large amounts of traffic coming from a single IP address
• • A flood of traffic from users who share a single behavioral profile, such as device type, geolocation, or web browser version
• • An unexplained surge in requests to a single page or endpoint
• • Odd traffic patterns, such as spikes at odd hours of the day
• • Patterns that appear to be unnatural (e.g., spikes every 15 minutes)

There are other, more specific signs of attacks that can vary depending on the type of DDOS attack.

Types of DDoS Attacks

Application Layer Attacks

DDoS Application Layer Attacks are sophisticated cyber threats designed to disrupt services by overwhelming the application layer, where user interactions occur. They fill the botnets with a complex request that overwhelms the target Server. And If the target Web Server receives thousands or millions of requests, it can be overwhelmed and either slow down or stop completely. Unlike traditional DDoS attacks that flood networks, these target specific application processes, such as HTTP, DNS, or database queries, simulating legitimate user behavior. By inundating servers with resource-intensive requests, attackers exhaust system capabilities, slowing or crashing services entirely. These attacks are stealthy, often harder to detect, and can cripple business-critical applications. Effective defense requires advanced traffic analysis, robust security protocols, and scalable infrastructure to distinguish malicious activity from genuine user interactions and maintain seamless service availability.

Protocol Attacks

This type of attack is focused on the networking layer of the target Web Server or Website. Its focus is to overwhelm the table space at the firewall, central network services or load balancer that sends requests to the target. Generally, network service follows the first in first out (FIFO) command, where the Server processes the first request before it goes to the next one. In a DDoS Attack, the queue can become so large that the Server lacks the resources to handle the first request.

Volumetric Attacks

The botnet is used to generate a large amount of traffic and block the works on the target – more of like an HTTP Flood attack, but with more exponential response component. Think of 50 orders coming in for 20 items each at the same store at the same exact time. When such an attack is directed to a Web Server, it will increase the response size, and the traffic amount explodes and clogs up the target.

Rate Limiting Attacks

Rate limiting restricts the volume of network traffic over a specific time period, essentially preventing Servers from getting overwhelmed by requests from IP addresses. Rate limiting can be used to prevent DDoS attacks that use botnets to spam an endpoint with an abnormal amount of requests at once. It is a strategy for managing and regulating traffic flow to ensure that the service remains available and responsive.

Why DDoS Protection is Crucial

DDoS attacks can have severe consequences for businesses and organizations:

• • Financial Loss: Prolonged downtime can result in lost revenue and additional recovery costs.
• • Reputation Damage: Customers lose trust in businesses that experience frequent disruptions.
• • Operational Disruptions: Attacks can cripple critical business operations, leading to inefficiencies.
• • Data Breaches: Some attackers use DDoS attacks as a smokescreen to distract from other malicious activities.

DDoS Attacks Are Evolving

In February 2018, there was the first-ever terabit-size DDoS attack. This was followed days later by an attack nearly twice that big, measuring 1.7 Tbps. (terabits per second).

Not only are more DDoS Attacks being launched today, but the attackers are also uncovering new ways to integrate the latest technologies for large scale attacks. In 2019, the attacks inclined towards big volumes and large websites, but in 2021 we have seen the highest level of attack ever recorded. And this is not about to slow down.

DDoS Disruption

Attackers are starting to combine the attacks with other expensive illegal activity that can raise the recovery cost to include compulsory customer notification, breach reporting, and more complex recovery.

DDoS Attacks are increasingly multilayered and multivector, using a blend of massive volume attacks and stealth infiltration. This is the newest trend in an evolving landscape where perpetrators adapt their services and utilize advanced tools and abilities to try to evade and overcome existing defenses. Organizations need to maintain a consistent vigilance on the methods used to target their systems and constantly adjust their defenses as per the industry standards to stay safe.

How To Prevent DDoS Attacks

A good hosting provider should have staff that is experienced in stopping DDoS attacks. In the event that you identified symptoms of a DDoS attack, contact your hosting provider and ask for their help. Depending on the Provider, they might have detected and stopped it before doing any harm.

But for any organization, the best solution is to plan ahead for a DDoS attack. Using a “Always On” type of protection or clear protocols in place for your business to follow when the attack occurs.
For example, instead of stopping all traffic, you might continue to allow users to use the website as much as you can. You could also switch to a different system to work from.

Businesses that are vulnerable to attacks on mobile devices should make sure that private devices connected to the corporate network have an approved mobile security solution to protect against infections. And the means to prevent installation of unauthorized apps. Your IT department should be vigilant in sniffing out and intercepting any malicious communications.

• • Never keep passwords written on post-it notes
• • Create strong passwords for all devices
• • Lock your computer when away
• • Completely log off at the end of the day
• • Ensure High Levels of Network Security
• • Have Server Redundancy
• • Continuous Monitoring of Network Traffic
• • Do not reveal your login credentials to anyone

If it is absolutely necessary to share login information, make sure that it is sent via encrypted channels.

Educate Your Team

Educating your team about DDoS attacks is crucial for ensuring a swift and effective response to these disruptive threats. Providing comprehensive training helps team members recognize the early signs of a DDoS attack, understand the appropriate response procedures, and implement preventative measures. By fostering a culture of awareness, you empower your staff to quickly identify anomalies in traffic patterns, coordinate with IT and security professionals, and execute predefined incident response plans. Regular training sessions and simulations not only keep the team informed about the latest attack techniques and mitigation strategies but also enhance their ability to act decisively under pressure. This proactive approach minimizes the potential impact of DDoS attacks and strengthens the overall resilience of your organization's digital infrastructure. Ensure that your team understands:

• • Attack Recognition: How to recognize the signs of a DDoS attack and the steps to take in response.
• • Response Procedures: Clearly defined procedures for responding to and mitigating attacks, including communication protocols and escalation processes.
• • Regular Training: Conduct regular training and simulations to keep your team up-to-date with the latest threats and mitigation techniques.

Responding to a DDoS Attack

Despite best efforts, some attacks may still succeed. Having a response plan is crucial to minimize damage:

• Detect the Attack: Monitor for unusual traffic patterns, such as sudden spikes or repeated requests from the same IP.
• Activate Mitigation Protocols: Enable rate limiting, block malicious IPs, and redirect traffic using a WAF or CDN.
• Communicate with Stakeholders: Notify your team, customers, and service providers about the incident.
• Engage Your DDoS Protection Provider: If using a DDoS protection service, contact them immediately for assistance.
• Analyze and Learn: Conduct a post-attack analysis to identify vulnerabilities and strengthen your defenses.

Leveraging AI for Advanced DDoS Mitigation

As DDoS attacks become more sophisticated, integrating artificial intelligence (AI) into mitigation strategies has revolutionized website protection. AI-driven systems analyze traffic patterns in real-time, distinguishing legitimate users from malicious botnets with high precision. By predicting attack behaviors and dynamically applying rate limits, these solutions effectively counter even subtle, short-lived attacks that traditional defenses might miss.

AI-powered DDoS protection ensures robust security, maintaining website uptime and safeguarding brand reputation against evolving cyber threats.
