What is an EDoS attack?
An Economic Denial of Service (EDoS) attack is a type of cyber attack that aims to disrupt or disable the online services of an organization. Unlike traditional DDoS (Distributed Denial of Service) attacks, which focus on overwhelming a target’s network infrastructure, EDoS attacks specifically target the financial resources of a victim, making it an attractive option for cyber criminals seeking financial gain.
EDoS attacks exploit vulnerabilities in an organization’s online infrastructure or business processes to cause financial harm. The attackers often flood the victim’s online platform with a massive number of requests or initiate fraudulent transactions, leading to increased operational costs, resource exhaustion, or financial losses.
Common Types of EDoS Attacks
1. Payment Processing Attack: In this type of attack, cyber criminals flood an organization’s payment system with a large number of illegitimate payment requests, overwhelming the system and causing it to slow down or crash. This tactic forces the victim to spend significant resources to process and verify the influx of requests.
2. Account Creation Attack: This attack involves automated or manual creation of a large number of accounts on an organization’s platform. By overwhelming the system with fake accounts, the attackers cause the victim to expend resources on managing and verifying the authenticity of each account, diverting valuable time and money.
3. Inventory Scrape Attack: E-commerce platforms that manage inventories are susceptible to this type of attack. Attackers target the platform by scrapping the entire inventory or individual products at a much higher rate than the platform can handle. This can lead to inaccurate stock information, operational delays, and financial losses.
Countermeasures for EDoS Attacks
1. Implement Rate Limiting: Protecting online resources by implementing rate limits can help reduce the impact of EDoS attacks. This involves setting limits on the number of requests allowed from a single IP address or account within a certain timeframe. By doing so, organizations can prevent overwhelming traffic or fraudulent activities.
2. Utilize Web Application Firewalls (WAFs): WAFs can detect and mitigate EDoS attacks by filtering incoming traffic based on predefined security rules. These rules can be customized to identify patterns or anomalies associated with EDoS attacks, providing an additional layer of protection to the online infrastructure.
3. Conduct Regular Security Audits: Regularly assessing and testing the security of an organization’s online infrastructure can help identify and address vulnerabilities before they are exploited. Conducting comprehensive penetration testing, vulnerability scanning, and code reviews can strengthen the defense against EDoS attacks.
4. Educate Staff and Users: Raising awareness among staff and users about the risks and potential indicators of EDoS attacks is vital. Training employees on secure coding practices, safe account management, and recognizing phishing attempts can help prevent successful attacks.
5. Monitor Network Traffic: Deploying network monitoring tools can help identify any suspicious or abnormal network traffic patterns. By monitoring incoming and outgoing traffic, organizations can detect and respond to EDoS attacks in a timely manner, mitigating potential damage.
By implementing these countermeasures, organizations can reduce the risk of falling victim to EDoS attacks and maintain the stability and integrity of their online services. Staying proactive in identifying and addressing vulnerabilities is crucial in the ever-evolving landscape of cyber threats.
