We have entered an era in which cyber-attacks can be more than disruptive and expensive. Investing in decent WAF DDOS Protection can save you time, money and frustration down the road.
– CISO
Key Challenges :
- A Canadian automobile giant faced a severe DDoS attack threat orchestrated by a determined hacktivist group
- The attacks disrupted the business’s online operations and posed significant financial risks, potentially costing the company thousands of dollars.
- The attackers, identified as Anonymous, employed a multi-stage strategy to launch DDoS attacks that led to downtime
- This Anonymous hacktivist group launched the DDOS attacks in 3 major steps.
- Prestrike Doxing: At this stage, the attacker sends a threatening message attributed to an anonymous person, demanding money from the customer by sharing some stolen customer details.
- Slow DDOS Attack: Over the course of a week, the attacker regularly threatened the customer by targeting their website with a slow DDOS attack, leading to the site’s slowness and irregular availability.
- Large DDoS Attack: In the third step, the attacker blocked the website access completely through a direct high-volume DDOS attack.
- After the last attack, the website went down & the customers started losing deals running through their online portal application. Here are some of the major effects faced by the customer after the DDoS attack:
- Inability to reach the client-server during a DDoS attack.
- Unable to receive customer information from the dealerships through their online portal.
- Inability to publish new deals/offers & for the clients, as the clients cannot visit the site and perform any payments or transactions.
- This spoilt the customer experience and led to too much inconvenience for the dealers as the attacks were targeted for over a week.
- The customer tried to block these attacks with their internal firewalls but couldn’t scale with their solution and felt the urgent need for a cloud-WAF solution with better detection and protection capabilities.
Strategy & Recommended Solution :
After understanding the above attack details, Indusface immediately deployed Apptrana WAAP/WAF in block mode and provided threshold-based protection with the default/core rules, which reduced the attacks by 60%.
For complete protection, the below-mentioned custom policies were deployed to protect from the DDoS attack:
- As the customer had the immediate need to make the website available during the downtime, AppTrana Cloud WAAP was made to auto-scale for the incoming traffic. This made sure that the business started running again smoothly.
- As a next step, the inbuilt rate-limiting with auto-suggestion of limits was enabled to control the frequency of requests by a user. This ensured that the attacker, even using multiple nodes/user agents, could make only a few requests, and each request was blocked quickly.
- Apptrana also performed IP reputation checks and blocked anything that was marked malicious as per our threat intelligence database.
- Further adding to the security levels, the solution provided advanced protection, including policies such as user-level tracking, honeypots, advanced input validation, and anomaly policies.
With the combination of all the above layers of defense, Apptrana WAAP made sure that the site was continuously running and mitigated all sorts of attacks in the run-time.
