4 AI-powered cyber threats and why AI cybersecurity is the most effective response

AI is shaping every aspect of our digital lives, including cybersecurity. What was once a field dominated by human ingenuity and manual processes has now become a battleground of algorithms and machine learning systems. The transformative power of AI is undeniable, but it comes with a paradox: it’s both a shield and a weapon.

As 2025 unfolds, cyber threats and defenses are escalating in sophistication, with AI driving innovations on both sides. This article explores four ways that attackers are leveraging AI to launch advanced cyberattacks and how security professionals are using the same technology to counter these threats effectively.

4 AI-powered cyber threats on the rise

The potential of AI to cause harm mainly lies in its capability to make traditional attack methods faster, more efficient, and harder to detect. Four of the most popular kinds of AI-driven threats shaping the current face of cybersecurity are automated phishing campaigns, social engineering, zero-day exploits, and deepfake attacks. Let’s look at them in detail.

1. Automated phishing campaigns

Phishing has always been the foundation of online criminal activities for decades. It was also the most reported kind of cybercrime last year, with nearly 300,000 FBI complaints accounting for about 34% of all reported cybercrimes. Traditional phishing relies on sending generic emails in bulk, hoping a fraction of recipients will fall for the bait.

AI changes the game entirely. With the use of NLP, attackers study linguistic patterns, formats of company emails, and social media profiles of individuals to create very personalized phishing messages. AI tools can even emulate the writing styles of CEOs or colleagues, making such emails sound highly convincing. AI-powered phishing systems can improve by failing: once a tactic doesn’t pay off, the system refines the approach and tries again. This iterative process makes phishing campaigns more successful over time.

2. AI-enhanced social engineering

While social engineering has been based on the exploitation of human psychology for a long time, with AI, the tactics have become more sophisticated and widespread. By analyzing vast amounts of data from social media, online forums, and leaked databases, AI lets attackers build detailed psychological profiles of their targets.

Imagine someone calling you, stating your last vacation, naming your pet, and even timing their call to your next meeting. AI makes these manipulative interactions alarmingly personal to create a false sense of trust.

These tactics are not only a danger to individuals but also to organizations, where attackers manipulate employees who have access to sensitive information with the help of AI. One example is AI-driven voice cloning, which has been used to impersonate executives to sanction fraudulent transactions, successfully bypassing security measures that were in place.

3. Zero-day exploits and AI-generated malware

AI is reshaping the cybersecurity threat landscape by automating tasks that once required significant human expertise and time. In the case of zero-day exploits—vulnerabilities in software that developers aren’t aware of—AI can rapidly analyze massive codebases to identify weaknesses before they’re patched. This accelerates the timeline for attackers, reducing the window of safety for organizations.

Malware development has also evolved with AI-driven automation. A key example is polymorphic malware, which constantly changes its structure to evade traditional detection methods like signature-based antivirus systems. While older malware could be recognized by its digital fingerprint, polymorphic malware morphs frequently, making it harder for defenses to keep up.

4. Deepfake attacks

Deepfake technology leverages AI to create realistic but fabricated audio and video content. While it has legitimate uses in, for example, entertainment and education, it also introduces significant security risks by enabling convincing impersonations and disinformation campaigns.

Attackers can use deepfakes to impersonate key individuals in video or audio calls, facilitating fraud, corporate espionage, or spreading false information. For instance, a fake executive could authorize a fraudulent wire transfer or deliver false statements, causing financial or reputational damage. Or deepfakes could simulate a company spokesperson announcing fake news, triggering market instability or harming investor confidence.

AI as a cybersecurity ally: fighting fire with fire

To counter sophisticated AI-powered threats, the best defense is one that also involves AI. AI-powered cybersecurity solutions are faster, more accurate, and more adaptive than their predecessors. Predictive threat detection, real-time defense, and endpoint security are three powerful AI tools to counter the threats mentioned above.

Predictive threat detection

Unlike traditional systems, which depend on predefined rules, AI detects behavioral patterns. This makes it difficult for attackers to exploit static defenses.

For example, AI can analyze network traffic and identify abnormal behavior that could be the precursor to an attack. Using machine learning models, these solutions use historical data to predict potential threats before they happen.

Real-time defense

AI reacts instantly, giving it an upper hand over human-led defenses. Upon identifying any malicious activity, an AI system can automatically release deployment mechanisms like isolating affected devices or blocking malicious activities.

This is particularly important when trying to prevent AI-driven zero-day exploits before they cause serious harm. AI-driven zero-day exploits can spread rapidly due to their automated nature. Traditional security responses rely on human detection and intervention, which can be slow, leaving systems exposed. Since zero-day exploits target previously unknown vulnerabilities, there are no pre-existing patches or defenses. AI-powered defenses, however, can recognize unusual patterns of behavior in real time, even if the specific exploit is unknown. This speed and adaptability are crucial when dealing with zero-day exploits, where time is the most critical factor.

Endpoint security

AI-powered cyberattacks on laptops, smartphones, and IoT devices include personalized phishing, adaptive malware, and deepfake-based authentication bypasses. These attacks exploit device vulnerabilities, automate data theft, and enable network intrusions faster than traditional methods.

AI-powered endpoint detection and response tools monitor these devices continuously for any form of suspicious activity. AI can flag unusual behavior, like a device accessing sensitive files at odd hours or connecting to an unknown IP address. By detecting these vulnerabilities early, AI will be able to neutralize the threat before it has time to spread.

Best practices for leveraging AI in cybersecurity

To fully harness AI while minimizing risks, organizations should:

  • Keep the AI models current: It’s important to make sure your AI model, through constant updating, uses state-of-the-art threat intelligence technology; otherwise, its effectiveness is compromised as the attack vectors keep changing with time.
  • Embed AI into existing tool sets: Integration of AI with encryption and multi-factor authentication, among other security means, forms a strong multi-layered defense.
  • Embrace transparency: Invest in explainable AI systems where the security teams understand and trust the decisions taken by the AI.
  • Collaborate and share intelligence: Sharing AI insights across sectors will improve collective resilience to new emerging threats.

Gcore Radar Q1–Q2 2025: three insights into evolving attack trends

Cyberattacks are becoming more frequent, larger in scale, and more sophisticated in execution. For businesses across industries, this means protecting digital resources is more important than ever. Staying ahead of attackers requires not only robust defense solutions but also a clear understanding of how attack patterns are changing.The latest edition of the Gcore Radar report, covering the first half of 2025, highlights important shifts in attack volumes, industry targets, and attacker strategies. Together, these findings show how the DDoS landscape is evolving, and why adaptive defense has never been more important.Here are three key insights from the report, which you can download in full here.#1. DDoS attack volumes continue to riseIn Q1–Q2 2025, the total number of DDoS attacks grew by 21% compared to H2 2024 and 41% year-on-year.The largest single attack peaked at 2.2 Tbps, surpassing the previous record of 2 Tbps in late 2024.The growth is driven by several factors, including the increasing availability of DDoS-for-hire services, the rise of insecure IoT devices feeding into botnets, and heightened geopolitical and economic tensions worldwide. Together, these factors make attacks not only more common but also harder to mitigate.#2. Technology overtakes gaming as the top targetThe distribution of attacks by industry has shifted significantly. Technology now represents 30% of all attacks, overtaking gaming, which dropped from 34% in H2 2024 to 19% in H1 2025. Financial services remain a prime target, accounting for 21% of attacks.This trend reflects attackers’ growing focus on industries with broader downstream impact. Hosting providers, SaaS platforms, and payment systems are attractive targets because a single disruption can affect entire ecosystems of dependent businesses.#3. Attacks are getting smarter and more complexAttackers are increasingly blending high-volume assaults with application-layer exploits aimed at web apps and APIs. These multi-layered tactics target customer-facing systems such as inventory platforms, payment flows, and authentication processes.At the same time, attack durations are shifting. While maximum duration has shortened from five hours to three, mid-range attacks lasting 10–30 minutes have nearly quadrupled. This suggests attackers are testing new strategies designed to bypass automated defenses and maximize disruption.How Gcore helps businesses stay protectedAs attack methods evolve, businesses need equally advanced protection. Gcore DDoS Protection offers over 200 Tbps filtering capacity across 210+ points of presence worldwide, neutralizing threats in real time.

No capacity = no defense: rethinking DDoS resilience at scale

DDoS attacks are growing so massive they are overwhelming the very infrastructure designed to stop them. Earlier this year, a peak attack exceeding 7 Tbps was recorded, while 1–2 Tbps attacks have become everyday occurrences. Such volumes were unimaginable just a few years ago.Yet many businesses still depend on mitigation systems that were not designed to scale alongside this rapid attack growth. While these systems may have smart detection, that advantage is moot if physical infrastructure cannot handle the load. Today, raw capacity is non-negotiable — intelligent filtering alone isn’t enough; you need vast, globally distributed throughput.Lukasz Karwacki, Gcore’s Security Solution Architect specializing in DDoS, explains why modern DDoS protection requires immense capacity, global distribution, and resilient routing. Scroll down to watch him describe why a globally distributed defense model is now the minimum standard for mitigating devastating DDoS attacks.DDoS is a capacity war, not just a traffic spikeThe central challenge in DDoS mitigation today is the total attack volume versus total available throughput.Attacks do not originate from a single location. Global botnets harness compromised devices across Asia, Africa, Europe, and the Americas. When all this traffic converges on a single data center, it creates a structural mismatch: a single site’s limited capacity pitted against the full bandwidth of the internet.Anycast is non-negotiable for global capacityTo counter today’s attack volumes, mitigation capacity must be distributed globally, and that’s where Anycast routing plays a critical role.Anycast routes incoming traffic to the nearest available scrubbing center. If one region is overwhelmed or offline, traffic is automatically redirected elsewhere. This eliminates single points of failure and enables the absorption of massive attacks without compromising service availability.By contrast, static mitigation pipelines create bottlenecks: all traffic funnels through a single point, making it easy for attackers to overwhelm that location. Centralized mitigation means centralized failure. The more distributed your infrastructure, the harder it is to take down — that’s resilient network design.Why always-on cloud defense outperforms on-demand protectionSome DDoS defenses activate only when an attack is detected. These on-demand models may save costs but introduce a brief delay while traffic is rerouted and protections come online.Even a few seconds of delay can allow a high-speed attack to inflict damage.Gcore’s cloud-native DDoS protection is always-on, continuously monitoring, filtering, and balancing traffic across all scrubbing centers. This means no activation lag and no dependency on manual triggers.Capacity is the new baseline for protectionModern DDoS attacks focus less on sophistication and more on sheer scale. Attackers simply overwhelm infrastructure by flooding it with more traffic than it can handle.True DDoS protection begins with capacity planning — not just signatures or rulesets. You need sufficient bandwidth, processing power, and geographic distribution to absorb attacks before they reach your core systems.At Gcore, we’ve built a globally distributed DDoS mitigation network with over 200 Tbps capacity, 40+ protected data centers, and thousands of peering partners. Using Anycast routing and always-on defense, our infrastructure withstands attacks that other systems simply can’t.Many customers turn to Gcore for DDoS protection after other providers fail to keep up with attack capacity.Find out why Fawkes Games turned to Gcore for DDoS protection

Protecting networks at scale with AI security strategies

Network cyberattacks are no longer isolated incidents. They are a constant, relentless assault on network infrastructure, probing for vulnerabilities in routing, session handling, and authentication flows. With AI at their disposal, threat actors can move faster than ever, shifting tactics mid-attack to bypass static defenses.Legacy systems, designed for simpler threats, cannot keep pace. Modern network security demands a new approach, combining real-time visibility, automated response, AI-driven adaptation, and decentralized protection to secure critical infrastructure without sacrificing speed or availability.At Gcore, we believe security must move as fast as your network does. So, in this article, we explore how L3/L4 network security is evolving to meet new network security challenges and how AI strengthens defenses against today’s most advanced threats.Smarter threat detection across complex network layersModern threats blend into legitimate traffic, using encrypted command-and-control, slow drip API abuse, and DNS tunneling to evade detection. Attackers increasingly embed credential stuffing into regular login activity. Without deep flow analysis, these attempts bypass simple rate limits and avoid triggering alerts until major breaches occur.Effective network defense today means inspection at Layer 3 and Layer 4, looking at:Traffic flow metadata (NetFlow, sFlow)SSL/TLS handshake anomaliesDNS request irregularitiesUnexpected session persistence behaviorsGcore Edge Security applies real-time traffic inspection across multiple layers, correlating flows and behaviors across routers, load balancers, proxies, and cloud edges. Even slight anomalies in NetFlow exports or unexpected east-west traffic inside a VPC can trigger early threat alerts.By combining packet metadata analysis, flow telemetry, and historical modeling, Gcore helps organizations detect stealth attacks long before traditional security controls react.Automated response to contain threats at network speedDetection is only half the battle. Once an anomaly is identified, defenders must act within seconds to prevent damage.Real-world example: DNS amplification attackIf a volumetric DNS amplification attack begins saturating a branch office's upstream link, automated systems can:Apply ACL-based rate limits at the nearest edge routerFilter malicious traffic upstream before WAN degradationAlert teams for manual inspection if thresholds escalateSimilarly, if lateral movement is detected inside a cloud deployment, dynamic firewall policies can isolate affected subnets before attackers pivot deeper.Gcore’s network automation frameworks integrate real-time AI decision-making with response workflows, enabling selective throttling, forced reauthentication, or local isolation—without disrupting legitimate users. Automation means threats are contained quickly, minimizing impact without crippling operations.Hardening DDoS mitigation against evolving attack patternsDDoS attacks have moved beyond basic volumetric floods. Today, attackers combine multiple tactics in coordinated strikes. Common attack vectors in modern DDoS include the following:UDP floods targeting bandwidth exhaustionSSL handshake floods overwhelming load balancersHTTP floods simulating legitimate browser sessionsAdaptive multi-vector shifts changing methods mid-attackReal-world case study: ISP under hybrid DDoS attackIn recent years, ISPs and large enterprises have faced hybrid DDoS attacks blending hundreds of gigabits per second of L3/4 UDP flood traffic with targeted SSL handshake floods. Attackers shift vectors dynamically to bypass static defenses and overwhelm infrastructure at multiple layers simultaneously. Static defenses fail in such cases because attackers change vectors every few minutes.Building resilient networks through self-healing capabilitiesEven the best defenses can be breached. When that happens, resilient networks must recover automatically to maintain uptime.If BGP route flapping is detected on a peering session, self-healing networks can:Suppress unstable prefixesReroute traffic through backup transit providersPrevent packet loss and service degradation without manual interventionSimilarly, if a VPN concentrator faces resource exhaustion from targeted attack traffic, automated scaling can:Spin up additional concentratorsRedistribute tunnel sessions dynamicallyMaintain stable access for remote usersGcore’s infrastructure supports self-healing capabilities by combining telemetry analysis, automated failover, and rapid resource scaling across core and edge networks. This resilience prevents localized incidents from escalating into major outages.Securing the edge against decentralized threatsThe network perimeter is now everywhere. Branches, mobile endpoints, IoT devices, and multi-cloud services all represent potential entry points for attackers.Real-world example: IoT malware infection at the branchMalware-infected IoT devices at a branch office can initiate outbound C2 traffic during low-traffic periods. Without local inspection, this activity can go undetected until aggregated telemetry reaches the central SOC, often too late.Modern edge security platforms deploy the following:Real-time traffic inspection at branch and edge routersBehavioral anomaly detection at local points of presenceAutomated enforcement policies blocking malicious flows immediatelyGcore’s edge nodes analyze flows and detect anomalies in near real time, enabling local containment before threats can propagate deeper into cloud or core systems. Decentralized defense shortens attacker dwell time, minimizes potential damage, and offloads pressure from centralized systems.How Gcore is preparing networks for the next generation of threatsThe threat landscape will only grow more complex. Attackers are investing in automation, AI, and adaptive tactics to stay one step ahead. Defending modern networks demands:Full-stack visibility from core to edgeAdaptive defense that adjusts faster than attackersAutomated recovery from disruption or compromiseDecentralized detection and containment at every entry pointGcore Edge Security delivers these capabilities, combining AI-enhanced traffic analysis, real-time mitigation, resilient failover systems, and edge-to-core defense.

Outpacing cloud‑native threats: How to secure distributed workloads at scale

The cloud never stops. Neither do the threats.Every shift toward containers, microservices, and hybrid clouds creates new opportunities for innovation…and for attackers. Legacy security, built for static systems, crumbles under the speed, scale, and complexity of modern cloud-native environments.To survive, organizations need a new approach: one that’s dynamic, AI-driven, automated, and rooted in zero trust.In this article, we break down the hidden risks of cloud-native architectures and show how intelligent, automated security can outpace threats, protect distributed workloads, and power secure growth at scale.The challenges of cloud-native environmentsCloud-native architectures are designed for maximum flexibility and speed. Applications run in containers that can scale in seconds. Microservices split large applications into smaller, independent parts. Hybrid and multi-cloud deployments stretch workloads across public clouds, private clouds, and on-premises infrastructure.But this agility comes at a cost. It expands the attack surface dramatically, and traditional perimeter-based security can’t keep up.Containers share host resources, which means if one container is breached, attackers may gain access to others on the same system. Microservices rely heavily on APIs to communicate, and every exposed API is a potential attack vector. Hybrid cloud environments create inconsistent security controls across platforms, making gaps easier for attackers to exploit.Legacy security tools, built for unchanging, centralized environments, lack the real-time visibility, scalability, and automated response needed to secure today’s dynamic systems. Organizations must rethink cloud security from the ground up, prioritizing speed, automation, and continuous monitoring.Solution #1: AI-powered threat detection forsmarter defensesModern threats evolve faster than any manual security process can track. Rule-based defenses simply can’t adapt fast enough.The solution? AI-driven threat detection.Instead of relying on static rules, AI models monitor massive volumes of data in real time, spotting subtle anomalies that signal an attack before real damage is done. For example, an AI-based platform can detect an unauthorized process in a container trying to access confidential data, flag it as suspicious, and isolate the threat within milliseconds before attackers can move laterally or exfiltrate information.This proactive approach learns, adapts, and neutralizes new attack vectors before they become widespread. By continuously monitoring system behavior and automatically responding to abnormal activity, AI closes the gap between detection and action, critical in cloud-native, regulated environments where even milliseconds matter.Solution #2: Zero trust as the new security baseline“Trust but verify” no longer cuts it. In a cloud-native world, the new rule is “trust nothing, verify everything”.Zero-trust security assumes that threats exist both inside and outside the network perimeter. Every request—whether from a user, device, or application—must be authenticated, authorized, and validated.In distributed architectures, zero trust isolates workloads, meaning even if attackers breach one component, they can’t easily pivot across systems. Strict identity and access management controls limit the blast radius, minimizing potential damage.Combined with AI-driven monitoring, zero trust provides deep, continuous verification, blocking insider threats, compromised credentials, and advanced persistent threats before they escalate.Solution #3: Automated security policies for scalingprotectionManual security management is impossible in dynamic environments where thousands of containers and microservices are spun up and down in real time.Automation is the way forward. AI-powered security policies can continuously analyze system behavior, detect deviations, and adjust defenses automatically, without human intervention.This eliminates the lag between detection and response, shrinks the attack window, and drastically reduces the risk of human error. It also ensures consistent security enforcement across all environments: public cloud, private cloud, and on-premises.For example, if a system detects an unusual spike in API calls, an automated security policy can immediately apply rate limiting or restrict access, shutting down the threat without impacting overall performance.Automation doesn’t just respond faster. It maintains resilience and operational continuity even in the face of complex, distributed threats.Unifying security across cloud environmentsSecuring distributed workloads isn’t just about having smarter tools, it’s about making them work together. Different cloud platforms, technologies, and management protocols create fragmentation, opening cracks that attackers can exploit. Security gaps between systems are as dangerous as the threats themselves.Modern cloud-native security demands a unified approach. Organizations need centralized platforms that pull real-time data from every endpoint, regardless of platform or location, and present it through a single management dashboard. This gives IT and security teams full, end-to-end visibility over threats, system health, and compliance posture. It also allows security policies to be deployed, updated, and enforced consistently across every environment, without relying on multiple, siloed tools.Unification strengthens security, simplifies operations, and dramatically reduces overhead, critical for scaling securely at cloud-native speeds. That’s why at Gcore, our integrated suite of products includes security for cloud, network, and AI workloads, all managed in a single, intuitive interface.Why choose Gcore for cloud-native security?Securing cloud-native workloads requires more than legacy firewalls and patchwork solutions. It demands dynamic, intelligent protection that moves as fast as your business does.Gcore Edge Security delivers robust, AI-driven security built for the cloud-native era. By combining real-time AI threat detection, zero-trust enforcement, automated responses, and compliance-first design, Gcore security solutions protect distributed applications without slowing down development cycles.Discover why WAAP is essential for cloud security in 2025
