Financial institutions and services are increasingly facing overwhelming online traffic due to Denial-of-Service (DDoS) attacks.
In the rapidly changing digital landscape, financial institutions are finding themselves at the forefront of a growing threat: distributed denial-of-service (DDoS) attacks. These cyber assaults, which are becoming increasingly sophisticated, are a significant concern for the industry due to the sensitive data and critical infrastructure they target.
The financial sector is the most targeted sector for DDoS attacks, with the rapid adoption of APIs in financial services expanding the potential attack surface for bad actors. These APIs, which power modern banking infrastructure, allowing banks to work with partners, are now a prime target for cybercriminals.
DDoS attacks often focus on organizations' websites, but there has been a notable increase in attacks on APIs as well. This trend is part of the growing malware-as-a-service trend, with DDoS being one of its subsets. In fact, DDoS attacks are increasingly being outsourced by cybercriminals, making it easier for a broader adversary base to launch these disruptions.
The study found that DDoS attacks peaked in October with 350 recorded events. The increasing effectiveness of DDoS attacks is a major concern for the financial industry, with each attack involving thousands or even millions of malicious activities. DDoS attacks pose a threat to payment infrastructure, making it crucial for financial institutions to find new ways to defend themselves.
To combat these sophisticated, multi-dimensional DDoS attacks, current trends in defense include the increasing use of AI-powered threat detection and automated response systems, real-time data monitoring, and strengthening identity and access management (IAM) protocols. Financial institutions are also investing heavily in business continuity planning (BCP), incident response plans (IRP), and continuous cyber hygiene training for staff.
However, challenges remain due to the growing scale and complexity of DDoS attacks, often leveraging AI and automation for more aggressive, high-volume assaults via accessible DDoS-for-hire (DDoS-as-a-Service) platforms. These platforms lower the barrier to launching such attacks, making them a formidable challenge for financial institutions.
Regulatory and compliance pressures also force financial firms to manage not only direct cyber threats but also risks introduced through complex third-party vendor ecosystems. Rigorous vendor risk management is essential to prevent security gaps.
Despite these efforts, the increasing scale, complexity, and accessibility of such attacks remain formidable challenges for financial institutions in 2025. Financial institutions must remain vigilant and continue to adapt their defensive strategies to stay ahead of the evolving threat landscape posed by multi-dimensional DDoS attacks amplified by cybercrime-as-a-service models.
The financial industry, with its rapid integration of technology in banking-and-insurance, is particularly vulnerable to cybersecurity threats, such as DDoS attacks, which target APIs and critical infrastructure. These sophisticated assaults, often outsourced by cybercriminals, pose a significant risk to the banking-and-insurance sector, particularly to payment infrastructure.
To counter these threats, the industry is investing in various defense strategies, including AI-powered threat detection, real-time data monitoring, stronger identity and access management (IAM) protocols, business continuity planning (BCP), incident response plans (IRP), and continuous cyber hygiene training for staff. However, the growing scale and complexity of DDoS attacks, facilitated by cybercrime-as-a-service models, continue to present formidable challenges for financial institutions in 2025.
