DDoS Attacks Surge Globally: Finance and Healthcare Sectors Hit Hardest
February 21, 2025
Effective modern defense strategies against DDoS attacks incorporate traffic analysis, rate limiting, and advanced solutions that offer real-time detection and automated responses.
Modern DDoS attacks have evolved to focus on application logic, making traditional defenses that rely solely on bandwidth management insufficient.
Interestingly, smaller, stealthy attacks from single sources can be more damaging than larger botnet attacks due to their difficulty in detection.
These attacks can be categorized into three main types: volumetric, protocol, and application layer attacks, each designed to exploit different vulnerabilities in network infrastructure.
Volumetric attacks aim to overwhelm network bandwidth, while protocol attacks take advantage of weaknesses in network protocols to deplete server resources.
DDoS attacks are on the rise, with a staggering 260% increase in the Asia-Pacific region and a 196% surge in the Americas from 2022 to 2023.
The financial sector has emerged as the primary target for these attacks, accounting for 30% of incidents in 2023, followed closely by healthcare at 14.2%.
Application layer attacks, which target Layer 7 of the OSI model, are particularly sophisticated as they can mimic legitimate traffic, complicating detection and mitigation efforts.
Attackers employ a variety of tools, including low-and-slow techniques that minimize bandwidth usage to evade detection, as well as flood attack tools that generate overwhelming traffic.
In response to these threats, organizations are advised to adopt multi-layered defense strategies that emphasize real-time detection and visibility into attack patterns to maintain business continuity.
