DDoS Attacks Hit Record Highs: An Evolving Threat Landscape Demands New Strategies

The digital world is under siege. A recent industry report has pulled back the curtain on the alarming reality of Distributed Denial of Service (DDoS) attacks, revealing not just a significant increase in volume and intensity, but also a sophisticated evolution in attacker tactics and target selection. For businesses of all sizes, across every sector, the message is clear: the threat landscape has changed, and your defense strategies must evolve with it.

Let’s break down the critical findings:

The Alarming Surge: More Attacks, More Power

The numbers are stark:

A Staggering 41% Surge: Compared to the same period in 2024, the volume of DDoS attacks has jumped by an eye-watering 41%. This isn’t just a minor fluctuation; it’s a significant escalation in malicious activity.
Over a Million Attacks: Total attacks soared from 969,000 in H2 2024 to a staggering 1.17 million in H1 2025. This means more organizations are facing disruption than ever before.
Record-Breaking Intensity: Peak attack intensity reached an unprecedented 2.2 Terabits per second (Tbps), surpassing the 2 Tbps peak from late 2024. To put this in perspective, an attack of this magnitude can utterly cripple even the most robust network infrastructure, bringing critical operations to a grinding halt.

Evolving Attack Patterns: Longer, Deeper, More Strategic

Attackers aren’t just sending more traffic; they’re getting smarter about how they send it. Their strategies are adapting to bypass traditional defenses:

Longer, More Sustained Assaults: Short, burst attacks (under 10 minutes) have decreased by 33%. Instead, attackers are opting for medium-duration attacks (10-30 minutes), which have nearly quadrupled. This shift helps them bypass automated defense systems often designed to mitigate brief, high-volume spikes, forcing organizations to sustain a prolonged defense.
Application-Layer Focus: There’s been a noticeable 10% increase in application-layer attacks. This indicates a move beyond simply flooding network bandwidth. Attackers are now targeting specific web applications and APIs, aiming to exploit vulnerabilities at a deeper level and disrupt business-critical services that rely on these applications.
Shifting Target Sectors: No One Is Truly Safe

The traditional target landscape is undergoing a significant transformation, meaning sectors that once felt relatively safe may now be in the crosshairs:

Gaming No Longer Primary: For years, the gaming sector was the most frequent target. Attacks here have dropped by 30%, indicating attackers are diversifying their focus.
Tech and Financial Services Rise: The technology sector and financial services both saw a 15% increase in attacks. These sectors represent immense value for attackers, whether through data theft, service disruption, or simply demonstrating capabilities.

Hosting Providers as Prime Targets: Alarming new data shows that hosting providers are becoming increasingly attractive targets. A successful attack on a hosting provider can create a devastating ripple effect, impacting countless businesses and websites that rely on their services.
Geographic Distribution: New Threat Sources Emerge

The sources of these attacks are also expanding:

Hong Kong, A New Hotspot: Hong Kong has emerged as a significant new source, accounting for 17% of network-layer attacks and 10% of application-layer attacks. This highlights the ever-shifting global nature of cyber threats.
Persistent Threats: The US and Netherlands continue to be among the top sources, reinforcing the global, distributed nature of these malicious campaigns.
What This Means for Your Business

The report’s message is unequivocal: businesses across all sectors need to reassess and strengthen their DDoS protection strategies. The days of basic mitigation are over. Attackers are becoming more strategic, expanding their targets beyond traditional sectors to critical infrastructure, financial services, and the very foundation of the internet itself (hosting providers).

It’s no longer enough to react; you must anticipate.

Invest in Robust, Multi-Layered Protection: Relying on a single defense mechanism is no longer sufficient. Integrate solutions that can detect and mitigate attacks at both the network and application layers.
Prioritize Real-Time Monitoring and Threat Intelligence: Stay ahead of evolving tactics by leveraging solutions that provide real-time insights into threat patterns and attack methodologies.
Develop a Comprehensive Incident Response Plan: Know exactly what steps your team will take before, during, and after a DDoS attack. This includes communication strategies, service restoration protocols, and post-incident analysis.
Regularly Test Your Defenses: Don’t wait for a real attack to discover vulnerabilities. Conduct regular stress tests and drills to ensure your systems and teams are prepared.

The digital threat landscape is dynamic, and DDoS attacks are a persistent, growing danger. By understanding the latest trends and proactively strengthening your defenses, you can help safeguard your operations and ensure business continuity in an increasingly hostile online world. Stay vigilant, stay protected.

The Rising Storm: Analyzing Gcore’s DDoS Report and Singapore’s Critical Cybersecurity Challenges

A 41% surge in global DDoS attacks signals unprecedented threats to Singapore’s digital economy

The cybersecurity landscape has entered a new phase of intensity, as revealed by Gcore’s Q1-Q2 2025 Radar report. With a staggering 41% increase in DDoS attack volumes compared to the same period in 2024, the findings paint a concerning picture of evolving cyber threats that have profound implications for Singapore’s position as a global financial and technological hub.

The Numbers Tell a Stark Story

Gcore’s comprehensive analysis reveals a cybersecurity environment under unprecedented strain. The total number of DDoS attacks surged from 969,000 in the second half of 2024 to 1.17 million in the first half of 2025—a trajectory that, if maintained, could see annual attack volumes exceed 2.3 million by year’s end.

Perhaps more alarming than the sheer volume is the sophistication and intensity of these attacks. The largest recorded attack peaked at 2.2 terabits per second (Tbps), surpassing the 2 Tbps threshold breached in late 2024. To put this in perspective, such an attack could theoretically overwhelm the entire internet infrastructure of smaller nations, highlighting the industrial-scale nature of modern cyber warfare.

Singapore’s Vulnerability Matrix: A Perfect Storm

Singapore’s unique position as a densely connected digital economy creates both opportunities and vulnerabilities that make the Gcore findings particularly relevant. The city-state’s status as a regional financial hub, coupled with its aggressive digitalization initiatives, places it squarely in the crosshairs of the threat trends identified in the report.

Financial Services Under Siege

The Gcore report’s identification of financial services as an increasingly targeted sector aligns ominously with Singapore’s economic profile. According to recent industry analysis, financial services account for 34% of DDoS attacks, with institutions being attractive targets due to the vast amounts of sensitive data and high-value transactions they manage.

Singapore’s financial sector faces a compound threat. The Monetary Authority of Singapore (MAS) oversees approximately 700 financial institutions, including major local and international banks, insurance companies, and a rapidly expanding fintech ecosystem. Recent data shows that in Singapore, organisations in the banking and financial services, government and technology sectors were the most frequently attacked, with 63% of all reported phishing attempts in 2023 involving spoofs of companies in the banking and financial services sector.

The shift from gaming to financial services as primary targets, as documented in the Gcore report, represents a strategic pivot by threat actors toward higher-value targets. This transition is particularly concerning for Singapore, where digital banking initiatives have accelerated rapidly, potentially expanding the attack surface.

The Tech Sector Crosshairs

The 15% increase in attacks on the technology sector highlighted in the Gcore report poses significant risks to Singapore’s ambitions as a regional tech hub. The country hosts major cloud service providers, data centers, and technology companies serving the broader ASEAN region. An attack on Singapore-based tech infrastructure could have cascading effects across multiple countries.

The report’s emphasis on hosting providers as prime targets is particularly relevant to Singapore’s digital infrastructure. The city-state serves as a major hosting hub for regional operations of global technology companies. As the Gcore analysis notes, “An attack on one hosting provider can have dangerous ripple effects: massive service outages and reputation damage to dozens of dependent companies.”

The Evolution of Attack Sophistication

Duration and Persistence: A New Threat Model

The Gcore report reveals a fundamental shift in attack methodology that has significant implications for Singapore’s cybersecurity posture. The 33% decrease in attacks lasting less than 10 minutes, coupled with a near-quadrupling of attacks lasting 10-30 minutes, indicates that threat actors are adapting to improved automated defense systems.

This evolution is particularly challenging for Singapore’s Critical Information Infrastructure (CII) operators. Banks and other CII operators must conduct regular cybersecurity risk assessments, comply with Cyber Security Agency of Singapore (CSA) codes, and report cybersecurity incidents affecting CII to CSA. However, traditional defense mechanisms optimized for brief, intense attacks may prove inadequate against these new sustained assault patterns.

Multi-Vector Complexity

The report’s identification of increasingly sophisticated multi-vector attacks poses particular challenges for Singapore’s regulatory framework. The Cyber Security Agency of Singapore has published guidance on DDoS mitigation, but the DDoS Mitigation Advisory provides guidance structured around the GIPDRR framework (Govern, Identify, Protect, Detect, Respond, Recover), which may require updating to address the evolving threat landscape.

The 10% increase in application-layer attacks identified in the Gcore report is especially concerning for Singapore’s digital services sector. These attacks target web applications and APIs—the backbone of modern digital banking, e-government services, and fintech applications that Singapore has embraced enthusiastically.

Geographic Threat Vectors: The Hong Kong Connection

One of the most significant findings in the Gcore report is the emergence of Hong Kong as a major source of DDoS attacks, accounting for 17% of network-layer and 10% of application-layer attacks. This development has direct implications for Singapore given the geographical proximity and interconnected nature of regional business networks.

The timing of this emergence is particularly noteworthy, coinciding with increased geopolitical tensions in the region. Singapore’s role as a neutral financial center means it must navigate these threats while maintaining its openness to international business—a delicate balance that becomes more challenging as regional threat vectors intensify.

Singapore’s Defensive Posture: Strengths and Gaps

Regulatory Framework

Singapore’s cybersecurity regulatory framework, anchored by the Cybersecurity Act and overseen by CSA, provides a robust foundation for defense. The Act allows CSA to proactively secure Systems of Temporary Cybersecurity Concern (STCCs), i.e., computer systems that are of higher risk due to temporary events or situations. This proactive approach is crucial given the dynamic nature of the threats identified in the Gcore report.

However, the speed of threat evolution may outpace regulatory adaptation. The emergence of new attack patterns, as documented in the Gcore report, suggests that Singapore’s regulatory framework may require more dynamic updating mechanisms to remain effective.

Critical Infrastructure Vulnerability

Singapore’s connection to 26 submarine cables makes these “backbone of the internet” connections a point of fragility for global connectivity, with key industries targeted including telecommunications, internet services, and banking & financial services. This infrastructure concentration, while providing redundancy, also creates attractive targets for the kind of sustained, sophisticated attacks documented in the Gcore report.

The recent focus on infrastructure attacks, combined with the report’s findings on longer-duration assaults, suggests that Singapore’s critical infrastructure faces evolving threats that may require enhanced protection strategies beyond current measures.

Economic Implications: The Cost of Vulnerability

The economic implications of the trends identified in the Gcore report are substantial for Singapore. As a trading nation heavily dependent on digital infrastructure, DDoS attacks can have cascading effects far beyond the immediate targets.

Financial Sector Risks

With financial services accounting for a significant portion of Singapore’s GDP, the targeting trends identified in the Gcore report pose systemic risks. A successful large-scale attack on Singapore’s financial infrastructure could disrupt not only local operations but also impact the broader ASEAN financial ecosystem, given Singapore’s role as a regional financial center.

Reputation and Trust

Singapore’s success as a financial and technological hub depends heavily on trust and reliability. The sophisticated, sustained attacks documented in the Gcore report could potentially undermine confidence in Singapore’s digital infrastructure if not adequately addressed.

Strategic Recommendations for Singapore

Enhanced Multi-Vector Defense

The shift toward multi-vector attacks identified in the Gcore report necessitates a corresponding evolution in Singapore’s defense strategies. Traditional perimeter-based security models may prove inadequate against the sophisticated, sustained attacks now prevalent.

Singapore should consider implementing:

Dynamic Defense Mechanisms: Systems capable of adapting to the longer-duration attacks now favored by threat actors
Cross-Sector Information Sharing: Enhanced coordination between financial, technology, and telecommunications sectors to identify and respond to multi-vector campaigns
Regional Cooperation Frameworks: Given the emergence of Hong Kong as a major attack source, Singapore may benefit from enhanced regional cybersecurity cooperation

Regulatory Evolution

The Gcore report’s findings suggest that Singapore’s regulatory framework may need updating to address:

Application-Layer Security Requirements: Given the 10% increase in application-layer attacks
Sustained Attack Resilience: Requirements for systems to withstand longer-duration attacks
Cross-Border Threat Management: Frameworks for addressing threats from emerging geographical sources

Private-Public Partnership Enhancement

The scale and sophistication of threats identified in the Gcore report exceed the capacity of individual organizations to address effectively. Singapore’s approach to cybersecurity may need to evolve toward more integrated public-private partnerships that can:

Share threat intelligence in real-time
Coordinate responses to large-scale attacks
Develop collective defense capabilities

The Path Forward: Adaptation and Resilience

The Gcore Q1-Q2 2025 Radar report serves as both a warning and a roadmap for Singapore’s cybersecurity future. The 41% increase in attack volumes, coupled with evolving attack methodologies and shifting target patterns, represents a fundamental shift in the threat landscape that demands a correspondingly comprehensive response.

Singapore’s strength lies in its ability to adapt rapidly to changing circumstances—a trait that will be essential in addressing the cybersecurity challenges ahead. The city-state’s compact size, strong governance structures, and high levels of digital connectivity provide advantages in implementing comprehensive cybersecurity measures quickly and effectively.

However, the window for action is narrowing. The trends identified in the Gcore report suggest that 2025 may be remembered as a inflection point in cybersecurity—the year when the threat landscape fundamentally shifted toward more sophisticated, sustained, and damaging attacks.

Conclusion: A Call to Digital Arms

The Gcore DDoS report is more than a statistical analysis; it is a clarion call for heightened vigilance and enhanced preparation. For Singapore, the implications are clear: the digital economy that has driven much of the nation’s recent success is under unprecedented threat.

The 41% surge in DDoS attacks, the shift toward longer-duration assaults, the targeting of financial services, and the emergence of new geographical threat sources all point toward a more challenging cybersecurity environment. Singapore’s response to these challenges will not only determine the security of its own digital infrastructure but may also influence the broader regional approach to cybersecurity.

As threat actors become more sophisticated and determined, Singapore must ensure that its defenses evolve at least as quickly as the threats they face. The cost of inadequate preparation, as the Gcore report makes clear, extends far beyond technical disruption to encompass economic, social, and strategic consequences that could undermine Singapore’s position as a trusted global hub.

The storm clouds are gathering in cyberspace. Singapore’s challenge is to weather this storm while continuing to harness the digital winds that have powered its remarkable growth. The time for action is now.

This analysis is based on public information and industry reports. Organizations should consult with cybersecurity professionals and relevant authorities for specific security guidance tailored to their circumstances.
