What is Cyber Warfare?
Cyber warfare is fundamentally defined as the application of technology, including computer networks and the internet, to carry out military operations and various hostile activities within cyberspace.
It involves deploying digital weapons to disrupt or destroy computer systems, pilfer sensitive information, or inflict other forms of damage on critical infrastructure or communication networks.
This type of conflict presents a significant threat to national security, economic stability, and individual privacy. Here are the key aspects of cyber warfare as described in the sources:
Nature and Objectives
Cyber warfare aims to inflict painful, asymmetric damage on an adversary from a distance. Its objectives include attacking an enemy's information systems, communication networks, and other critical infrastructure to gain strategic and tactical advantages.
It can lead to the disruption or destruction of computer systems, theft of sensitive information, or damage to essential services like power grids, water supplies, and transportation networks.
The ultimate goal is often control over information, infrastructure, and power.
Beyond direct damage, cyber warfare can be used for espionage, sabotage, economic disruption, propaganda, and can even precede physical attacks. While potentially devastating, cyber attacks alone may not achieve the lethality of traditional strategic weaponry.
Actors Involved
Cyber warfare can be executed by both state and non-state actors.
While typically involving one nation-state attacking another, non-state actors like terrorist organizations or hacktivists can also be involved, sometimes working to further the goals of a hostile nation.
Increasingly, cybercriminals are being co-opted by nation-states to conduct espionage, destabilize economies, and support military operations, blurring the lines between financial crime, state-sponsored espionage, and warfare.
Characteristics of Attacks
Cyber attacks can be launched remotely and anonymously, making it easier for perpetrators to hide their tracks compared to conventional warfare.
They often employ sophisticated techniques such as advanced persistent threats (APTs) and zero-day exploits.
The rise of Artificial Intelligence (AI) is significantly reshaping cyber warfare, enabling more complex, automated, and adaptive attacks, including AI-driven malware that can learn and adapt to defenses.
This domain of conflict transcends borders, sovereignty, and even time, as seen in incidents like the 2007 Estonia cyber attack.
Challenges and Ethical Considerations
A significant challenge is the lack of a universal, formal definition for what constitutes an act of cyber warfare. Experts debate what level of activity or damage qualifies as cyber warfare, with some suggesting it only applies when an attack results in death.
The anonymity inherent in the internet's design makes attributing cyber attacks difficult, as perpetrators can hide their tracks, mimic other threat actors, or engage in false flag operations to deflect blame. Detection latency and a lack of visibility further complicate investigations. Even when evidence is found, it can be ambiguous, potentially pointing to multiple entities. This ambiguity complicates deterrence and retaliation.
Cyber warfare raises numerous ethical concerns, including the potential for unintended harm to civilians and non-military targets, issues of proportionality and discrimination, and questions about national sovereignty.
The international legal framework for cyber warfare is still evolving, posing challenges for accountability and the application of existing laws like the Geneva Conventions.
What types of cyber attacks exist?
Cyber attacks encompass a broad spectrum of malicious activities conducted within cyberspace, employing technology to achieve various objectives, ranging from financial gain to military and political goals. They pose significant threats to national security, economic stability, and individual privacy.
Here are the main types of cyber attacks and related activities as described in the sources:
Espionage:
This involves monitoring other countries to steal secrets and sensitive information. It can use sophisticated techniques like spear phishing attacks and botnets to compromise computer systems. Chinese espionage groups have disguised their activities as ransomware attacks to steal intellectual property.
Russian intelligence services have also leveraged cybercriminal networks to steal classified information from European governments.
Examples include Chinese hackers stealing information related to the F-35 fighter jet design and trade secrets from US companies in technology, pharmaceuticals, and energy.
Pegasus spyware, used to target journalists, activists, and politicians, also falls under surveillance and espionage.
Sabotage:
This involves the theft, destruction, or compromise of sensitive information by hostile governments or terrorists, sometimes leveraging insider threats from dissatisfied or careless employees.
The Stuxnet worm, a sophisticated cyber weapon, was designed to sabotage Iran's nuclear program by subtly altering centrifuge speeds to cause physical damage.
Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks:
These attacks aim to prevent legitimate users from accessing a website or service by overwhelming it with fake requests. They can disrupt critical operations, block access to sensitive websites, and cripple government, banking, and media websites. Black market botnets provide massive DDoS resources with a high level of anonymity.
Malware Attacks:
This is a broad category involving malicious software.
Ransomware:
This type of malware encrypts a victim's files, demanding payment (often cryptocurrency) for their release.
It has evolved to be used by nation-states to destabilize economies and support military operations.
Examples include the Colonial Pipeline attack, the CONTI group's attack on Costa Rica's government systems, and the NotPetya attack attributed to Russia against Ukraine.
North Korea and Iran have used ransomware for fundraising and intelligence gathering.
Worms:
Self-replicating malicious programs that spread across networks. Stuxnet is a prime example of a sophisticated worm used for strategic military purposes.
WannaCry is another ransomware worm that affected hundreds of thousands of computers globally.
Trojans and Spyware:
Malicious programs disguised as legitimate software.
The X-Agent spyware, spread via an infected Android application, was attributed to the Russian group Fancy Bear and reportedly led to the destruction of over 80% of Ukraine's D-30 Howitzers.
Pegasus spyware is another example, designed to be installed on phones to access data without the target's knowledge.
Rootkits, Cryptojacking, Backdoor Attacks:
Other forms of malware for stealthy access and resource hijacking.
AI-driven Malware:
These are advanced forms of malware that can adapt their behavior in reaction to defenses, learn from errors, and modify their tactics, making them very difficult to detect and counteract.
Attacks on Critical Infrastructure: These target essential services.
Electrical Power Grid Attacks:
Aim to disable critical systems, disrupt infrastructure, and cause physical harm or widespread blackouts.
Examples include the 2015 blackout in Ukraine, a "surgical strike" on energy distribution companies, and past investigations into Chinese hacking attempts on a California electric power grid test network.
Water Supply Systems:
Vulnerable to cyber attacks, as seen in the 2021 incident in Oldsmar, Florida, where a hacker attempted to poison the water supply.
Foreign actors have also been linked to attacks on water facilities in Pennsylvania, Indiana, and Texas.
Transportation Networks and Financial Systems:
These are also critical infrastructures susceptible to disruption, potentially leading to widespread chaos and economic instability.
Propaganda Attacks and Information Operations:
These attempts control the minds and thoughts of people in a target country by exposing embarrassing truths, spreading lies, or eroding public trust in authorities.
This can involve psychological warfare and disinformation campaigns, including the use of fabricated images like deepfakes. The Russian interference in the 2016 US elections, involving the hacking and dissemination of stolen emails, is a significant case study in this area.
Economic Disruption:
Targeting the computer networks of economic establishments like stock markets, payment systems, and banks to steal money or block access to funds.
Cybercrime, generally, has evolved into a national security threat, blurring lines between financial crime and warfare.
Surprise Attacks/Digital Pearl Harbor:
These are massive, unexpected attacks designed to weaken enemy defenses and potentially prepare the ground for a physical attack.
The cyber attack on Syrian air defense systems reportedly preceded an Israeli air force strike on an alleged nuclear reactor, demonstrating this concept.
Data Breaches and Data Leaks:
Involve the unauthorized access and theft of sensitive corporate and government data, which can then be leaked online for espionage or to cause reputational damage.
Notable examples include the 2014 Yahoo data breach, the 2011 PlayStation Network attack, the 2013 Adobe cyber attack, and the Marriott data breach.
Web Attacks:
Website Defacement:
Changing the homepage text or content of a website.
Injection Attacks:
Such as SQL Injection, NoSQL Injection, Command Injection, HTML Injection, where malicious code is inserted into input fields.
Cross-Site Scripting (XSS) Attacks:
Injecting malicious scripts into web pages viewed by other users.
Cross-Site Request Forgery (CSRF) Attacks:
Tricking a web browser into executing an unwanted action in an application where the user is authenticated.
DDoS and Other Attacks:
On websites and APIs to prevent legitimate users from accessing services or to exploit vulnerabilities.
Network Attacks:
Man-in-the-Middle (MITM) Attacks:
Intercepting communication between two parties.
ARP Spoofing, DNS Spoofing, DNS Hijacking, Sybil Attack, Pharming, IP Blacklist: Various techniques to manipulate network traffic or identity
Social Engineering:
Manipulating individuals into divulging confidential information or performing actions that compromise security.
This includes phishing, spear phishing, vishing attacks, account takeover, brute force attacks, credential stuffing, session hijacking, and insider threats.
Malware Distribution: Using methods like malvertising (malicious advertising) and drive-by downloads to spread malware.
Advanced Persistent Threats (APTs):
Highly sophisticated and stealthy cyber attacks conducted over a prolonged period, often by state-sponsored actors, to gain persistent access to a network and steal data.
Zero-Day Exploits: Exploiting newly discovered software vulnerabilities before a patch is released, often used in sophisticated state-sponsored attacks.
Fraud Attacks:
Including Magecart (e-commerce skimming), carding, and credit card cracking.
Automated Bots and Machine Learning Algorithms: Used by adversaries to conduct large-scale and subtle attacks that can evade conventional detection techniques.
AI is increasingly enabling attackers to plan and implement more comprehensive and precise attacks, including large-scale DDoS attacks and exploiting zero-day vulnerabilities at high speed.
These diverse types of cyber attacks reflect the dynamic and evolving nature of cyber warfare, requiring comprehensive and adaptable defense strategies.
How has cyber warfare evolved from hacktivism to state-sponsored attacks?
Cyber warfare has significantly evolved from its origins in hacktivism to its current status dominated by sophisticated state-sponsored attacks.
This transformation reflects an increase in complexity, resources, and the strategic objectives of the actors involved. Here's how cyber warfare has evolved:
Early Days: Hacktivism and Cybercrime
The origins of cyber warfare can be traced back to hacktivism and cybercrime. Hacktivists were individuals or groups who used hacking as a form of activism, often motivated by political statements or mischief. Early actions typically involved website defacement and the theft of sensitive information, which were initially perceived more as nuisances than significant threats.
Hacktivists played a crucial role in shaping the cyber warfare landscape by pushing the boundaries of what was possible, thereby laying the groundwork for more sophisticated actors and prompting improvements in cybersecurity measures by governments and organisations.
Notable Early Examples:
Estonia (2007):
One of the earliest significant examples was the massive distributed denial-of-service (DDoS) attack on Estonia following a diplomatic dispute with Russia.
This attack crippled government and banking websites, highlighting the vulnerability of modern societies to cyber threats.
It was seen as an "awakening to a new form of conflict".
Georgia (2008):
During its conflict with Russia, Georgia experienced cyber attacks, including DDoS attacks and government website defacements. This incident demonstrated the potential for cyber warfare to precede or accompany physical conflict as a tool of statecraft.
The Rise of State-Sponsored Attacks
As cyber warfare progressed, nation-states began to take a more active role, backed by significant resources and increased sophistication. Their motivations expanded to include espionage, sabotage, and influencing political outcomes.
State-sponsored attacks are characterised by their complexity and significant impact, often employing advanced persistent threats (APTs) and zero-day exploits.
Unlike domestic cyber terrorism, state-sponsored cyber warfare originates from a foreign government that either directly plans or funds the attack.
These attackers may seek moral victories, send warnings to adversaries, or directly harm enemies, often operating with a sense of protection behind government backing.
Why Countries Engage in Cyber Warfare:
Countries engage in cyber warfare because it can be a relatively inexpensive means of attacking enemies compared to conventional warfare, especially for nations that cannot maintain a large conventional army. It allows them to fight from within their borders' safety.
Additionally, it can make the attacking country appear strong both domestically and internationally if publicised, and it is easier to hide one's tracks than with physical attacks.
Blending with Cybercrime:
More alarmingly, some governments now co-opt cybercriminal networks or directly employ cybercriminals to carry out attacks, buying hacking tools or leveraging existing criminal groups. This allows governments to deny responsibility while benefiting from stolen data, financial disruptions, and espionage.
For instance, Russia's GRU-linked APT44 (Sandworm) has used ransomware tools developed by criminal hackers to disrupt Ukrainian infrastructure, and North Korean groups have stolen cryptocurrency to fund their weapons programs.
Examples of State-Sponsored Cyber Warfare Operations:
Stuxnet (2010):
This was a sophisticated computer worm believed to be a joint American/Israeli cyberweapon.
It was designed to target and sabotage Iran's nuclear centrifuges by subtly altering their speeds while reporting normal operations.
Stuxnet demonstrated the potential for cyber warfare to cause significant physical harm and was one of the first known instances of a cyber weapon used for strategic military purposes.
Its use raised significant ethical concerns about unintended harm, the potential for a cyber arms race, and the need for transparency and accountability.
NotPetya (2017):
Initially thought to be ransomware, NotPetya was later attributed to Russia and designed to target Ukraine. It caused widespread damage both within Ukraine and globally, highlighting the far-reaching consequences of state-sponsored cyber attacks.
Russian Interference in US Elections (2016):
Attributed to Russian hackers believed to be affiliated with the Russian government, this multi-faceted attack involved hacking the Democratic National Committee (DNC) and disseminating stolen emails.
It led to a loss of public trust in the democratic process and raised ethical concerns about foreign interference in elections and the impact of cyber warfare on free and fair elections.
Chinese Cyber and Industrial Espionage:
China has been accused of state-sponsored cyber and industrial espionage, including the theft of intellectual property and trade secrets from foreign companies and access to sensitive government information.
Examples include the theft of F-35 fighter jet designs from Lockheed Martin and trade secrets from US companies like Westinghouse Electric. This undermines fair competition and innovation, raising ethical questions about state-sponsored theft.
North Korean Cyber Attacks:
North Korea has been accused of state-sponsored attacks against South Korea and private companies, like the Sony Pictures hack (2014), which was believed to be in response to "The Interview" film.
These attacks involved stealing sensitive data and causing reputational damage, raising ethical concerns about privacy violations, intellectual property rights, and the potential for escalation.
North Korea's cybercriminal groups have also stolen billions in cryptocurrency to fund their weapons program.
What are the most significant threats posed by cyberattacks on critical infrastructure?
Cyberattacks on critical infrastructure pose a multitude of significant threats that extend beyond mere digital disruption, impacting national security, economic stability, and the well-being of citizens. The most significant threats include:
Widespread Disruption and Physical Damage to Essential Services:
Cyberattacks aim to disrupt or destroy computer systems, steal sensitive information, or cause damage to critical infrastructure or communication networks.
A primary fear is the loss of infrastructure and power grids, given that electricity is indispensable and underpins all other critical systems. Such attacks can lead to lasting blackouts, disrupt a wide array of services, and jeopardize public health and safety.
For instance, the 2015 cyberattack on Ukraine's power grid compromised energy distribution companies, causing power outages for 230,000 people, which was considered a "surgical strike against sovereignty". Similarly, the 2007 cyberattack on Estonia crippled government and banking websites.
In a full-scale cyber war, hackers intend to create chaos and destruction by causing critical systems such as dams and nuclear plants to malfunction in dangerous and potentially deadly ways. An example of this potential was the Iranian hackers gaining access to a dam's control system in Rye Brook, New York.
Modern critical infrastructures are highly interconnected with the digital world, rendering them both their "lifeblood and greatest vulnerability".
Vulnerabilities exist in systems like municipal water systems, which often rely on outdated technology and lack robust cybersecurity, as highlighted by incidents like the attempted poisoning of a water supply in Oldsmar, Florida. Assessments have shown that 100% of examined water and wastewater plants were highly susceptible to external attacks.
Compromise of National Security and Economic Stability:
Cyber warfare directly threatens national security and economic stability. It can weaken national security and cause economic disruption by targeting critical financial systems like stock markets, payment systems, and banks to steal money or block access to funds.
State-sponsored cyber espionage, exemplified by China's theft of intellectual property and trade secrets, undermines fair competition and can lead to economic instability and national security compromises.
Cyberattacks serve as a tool of statecraft, enabling countries to exert influence without conventional military means, carrying significant risks of escalation and international destabilization.
The 2021 Colonial Pipeline ransomware attack, while financially motivated, underscored how such disruptions could cripple supply chains, ignite economic panic, and even alter the outcome of military operations.
Cybercrime has evolved into a global security threat, with nation-states increasingly co-opting cybercriminal networks for espionage, destabilizing economies, and supporting military objectives.
Data Theft, Loss of Privacy, and Erosion of Trust:
Cyberattacks frequently involve data theft, encompassing sensitive corporate, government, and personal information such as names, addresses, phone numbers, email addresses, passport numbers, and payment details.
The 2014 Yahoo data breach, affecting 500 million user accounts, showcased how state-sponsored actors can conduct large-scale identity theft, financial fraud, and espionage.
Attacks on private entities, like the Sony Pictures hack or the Marriott data breach, result in violations of privacy, damage to reputation, and substantial financial losses.
Propaganda attacks aim to manipulate public opinion by exposing truths, spreading lies, and eroding trust in authorities. The use of deepfakes and other AI-generated content can lead to psychological warfare and disinformation campaigns, destabilizing governance and public trust.
The Russian interference in the 2016 US elections notably resulted in a loss of public trust in the democratic process.
Escalation of Conflict and Ambiguity in Attribution:
The employment of cyberattacks raises profound ethical questions regarding the use of force and the appropriate boundaries for military operations, posing risks of unintended collateral damage and escalation.
The anonymity inherent in cyber warfare makes accurate attribution incredibly challenging, complicating deterrence and retaliation strategies, as it is often difficult to ascertain the perpetrator. This can also lead to false accusations.
Cyberattacks have the potential to escalate tensions between nations and lead to broader conflicts.
Existing international laws and traditional concepts of sovereignty and deterrence are often ill-suited to the complexities of cyber warfare, leaving significant legal and regulatory gaps.
Persistent Vulnerability and Challenges in Defense:
There is a growing concern about national security threats stemming solely from computer network attacks as critical infrastructures become increasingly digitized and connected to the Internet.
Experts warn that the public remains largely unaware of the imminent danger posed by massive cyberattacks that could potentially plunge society into a "dark age of confusion and panic".
The sheer volume of vulnerabilities in hyper-connected systems may be overwhelming to defend against, despite dedicated efforts by cybersecurity professionals. Critical infrastructure often employs outdated technology and lacks robust cybersecurity measures.
Cyber attackers constantly develop new methods to compromise systems and steal, delete, or modify information. They leverage advanced persistent threats (APTs) and zero-day exploits.
The integration of Artificial Intelligence (AI) is expected to enable more sophisticated, autonomous, stealthy, and personalized attacks, making detection and counteraction even more difficult.
The proliferation of Internet of Things (IoT) devices further expands the potential attack surface, creating new avenues for cyber threats.
What strategies and challenges exist for attributing and defending against cyberattacks?
Attributing and defending against cyberattacks present a complex array of strategies and challenges in the evolving landscape of cyber warfare.
Challenges for Attributing Cyberattacks
Attribution, which involves identifying the perpetrator of a cyberattack, is crucial for effective incident response and strengthening defenses. However, it faces significant challenges:
Internet Anonymity The internet is designed to favor anonymity, which benefits malicious actors like cybercriminals and terrorists.
Sophisticated Attacker Tactics Attackers use advanced techniques such as code obfuscation, polymorphic designs, fileless malware, dynamic attack infrastructure, and traffic blending, which render traditional static indicators of compromise (IOCs) largely ineffective.
Mimicking and False Flag Operations Perpetrators may deliberately mimic other threat actors or mount false flag operations to deflect blame, hide their intelligence efforts, or create conflict between countries.
Detection Latency and Lack of Visibility Cyberattacks like data breaches or low-and-slow Advanced Persistent Threat (APT) attacks can remain undetected for months, allowing attackers ample time to dispose of assets, scramble attack infrastructure, and erase evidence.
Low visibility is often due to gaps in monitoring, insufficient logging, or deliberate log purging.
Ambiguous Evidence Even when clues are found, they might point to multiple entities, especially if attackers borrow components from others or if multiple attacks overlap on a single target.
Lack of Transparency Many governments and military organizations are not transparent about their cyber warfare capabilities, which hinders accountability.
Unclear Legal Status There is no universal, formal definition for what constitutes an act of cyber warfare, and the international legal framework is still evolving, making accountability difficult.
Difficulty in Identifying Combatants The nature of cyberspace makes it challenging to distinguish between military and civilian targets, as well as combatants, raising ethical issues.
Dangers of Rushing Attribution Premature attribution risks prosecuting the wrong actor, disclosing crucial evidence or attribution methods to the actual attacker, or missing the true target or purpose of the attack (e.g., a website defacement serving as cover for a deeper intrusion).
Strategies for Attributing Cyberattacks
To overcome these attribution challenges, various strategies are being developed:
Reliance on Tactics, Techniques, and Procedures (TTPs) As static IOCs become less useful, defenders increasingly rely on TTPs built on behavioral models, looking for clues such as language indicators in compiled code, file modification time zones, or accidental access to command and control (C&C) servers from identifiable IPs.
Leveraging Artificial Intelligence (AI) AI, particularly machine learning, has the potential to improve attribution accuracy by analyzing vast numbers of attack indicators and uncovering patterns that human analysts might miss. However, this requires extensive data collection and prior attributions to train the AI systems.
Cloud Platform Capabilities Cloud platform providers possess the scale and resources to consolidate cloud-wide and application-specific data, integrating with AI-driven security analytics tools to enhance attribution accuracy.
Public Sector Collaboration Governments can aid in attribution by consolidating attack indicators across major players and augmenting them with human, signal, and open-source intelligence.
Coordinated Offensive Response For high-confidence targets, the government's role includes coordinating a broad range of offensive actions—from cyber countermeasures to diplomatic and economic sanctions—to shield private companies from legal and political repercussions.
Challenges for Defending Against Cyberattacks
Defending against cyberattacks is a continuous battle due to several persistent challenges:
Rapidly Evolving Threats The technology and tactics of cyber warfare are constantly evolving, making it difficult for defenses to keep pace. AI-driven attacks are becoming more complex, automated, and adaptable, enabling adversaries to operate on a large scale and with stealth.
>Expanding Attack Surface Increasing reliance on interconnected devices, such as those in the Internet of Things (IoT), expands the potential attack surface, creating new vulnerabilities.
Vulnerability of Critical Infrastructure Many national critical infrastructures, including power grids, water supplies, transportation, and financial systems, are increasingly computerized and connected to the internet, making them prime targets and dangerously susceptible to attack.
These systems often rely on outdated technology and lack robust cybersecurity measures.
AI's Dual Use While AI can bolster defenses, it also significantly enhances attacker capabilities, enabling more sophisticated and autonomous attacks, including AI-powered malware that can adapt its behavior to evade detection.
Adversarial Machine Learning Attackers can specifically design malicious data to exploit vulnerabilities in AI models used for defense, allowing them to evade detection.
False Positives and Negatives in AI AI systems, despite their advantages, can still produce false positives (flagging benign behavior as malicious) or, more critically, false negatives (missing actual threats).
Privacy Concerns AI-powered cybersecurity solutions often require analyzing vast amounts of data, including user behavior, which raises significant privacy concerns and legal compliance challenges (e.g., GDPR).
Decentralized Cybercrime Economy Cybercriminal organizations operate across borders with decentralized structures, making them challenging to track and dismantle.
Ethical Dilemmas Cyber warfare raises complex ethical questions regarding proportionality, discrimination between combatants and civilians, sovereignty, privacy, and human rights, which complicate the development of clear guidelines.
Strategies for Defending Against Cyberattacks
Countries and organizations can employ a multi-faceted approach to mitigate the risks of cyber warfare:

Endpoint Protection and Response (EDR):
Integrate AI into EDR tools to monitor endpoint devices, facilitate immediate incident response, and provide forensic insights into hacker tactics.
What are recent cyberattack trends?
Recent cyberattack trends indicate a landscape of increasing sophistication, speed, and strategic targeting, driven by emerging technologies and global instability. Here are the key trends:
Increased Sophistication and Speed
Cyberattacks are becoming more sophisticated, executing faster, and impacting a wider array of sectors. Attackers are adapting rapidly, targeting more strategically, and leveraging new technologies and global instability.
AI-Generated Attacks are a significant driving factor, lowering the entry barrier for cybercrime and enhancing the scale, speed, and effectiveness of existing attack methods.
This includes a predicted surge in ransomware attacks, large-scale phishing, and disinformation campaigns that employ more convincing fake audio, video, and images. Cybercrime is projected to cost $15.6 trillion globally by 2029, largely due to AI.
Accelerated Zero-Day Exploitation is a major concern. There's a spike in the exploitation of zero-day vulnerabilities (flaws exploited before patches are released), particularly in widely used platforms like Windows, Exchange, and VMware. Over 25% of vulnerabilities exploited in Q1 2025 were attacked within 24 hours of disclosure, putting intense pressure on IT and security teams.
Dominance of Privilege Escalation flaws has emerged, especially in systems like Windows Common Log File System (CLFS). These are increasingly popular among ransomware operators for zero-day exploitation, accounting for over half of all zero-days exploited in 2025 so far.
Overwhelming CVE Volumes (Common Vulnerabilities and Exposures) are making it difficult for defenders to prioritize patching. Over 40,000 CVEs were disclosed in 2024, with projections of nearly 50,000 in 2025.
Vulnerability exploitation was linked to 20% of breaches in the 2025 Verizon Data Breach Investigations Report (DBIR), placing it on par with stolen credentials and ahead of phishing as a breach vector.
Ransomware as a Top Threat
Ransomware continues to evolve and remains a primary global threat.
Advancements in AI and increasingly sophisticated techniques, including double extortion tactics (encrypting and exfiltrating data, then threatening public release) and supply chain compromises, are expected to increase its prevalence.
The emergence of Ransomware-as-a-Service (RaaS) platforms has democratized access to ransomware tools, enabling more cybercriminals to participate.
With AI and automation, ransomware operators are now moving faster, sometimes encrypting and exfiltrating data within hours of initial access.
Global Scale and Geopolitical Influence
Nation-state actors are increasingly leveraging cyber capabilities to conduct global-scale attacks, targeting critical infrastructure, multinational corporations, and supply chains. These attacks often involve cross-border collaboration among cybercriminal groups, hacktivists, and state-sponsored actors.
Governments remain high-value targets, becoming the third most targeted sector by nation-state actors. These attacks frequently aim to gather intelligence, disrupt operations, or influence political outcomes. For example, Russian hackers increased attacks on Ukraine by nearly 70% in 2024, with 4,315 incidents targeting critical infrastructure, government services, energy, and defense. Chinese groups doubled attacks on Taiwan to 2.4 million daily attempts in 2024.
The war in Ukraine has significantly increased the perceived threat of cyberwarfare, with over 64% of IT and security professionals surveyed agreeing that it has created a greater threat. This has led to increased threat activity on networks globally.
There is a growing concern about "kinetic cyber threats", where cyberattacks move beyond espionage to cause physical harm or destruction, such as the 2017 Triton malware attack on a Saudi Arabian petrochemical plant's safety systems or the 2021 attempt to poison a U.S. city's water supply.
Evolving Targets Across Different Sectors
Cyberattacks are increasingly targeting specific, high-value sectors, moving beyond broad, opportunistic campaigns.
Critical Infrastructure (CI) systems (e.g., power grids, water systems, financial institutions, communication networks) are prime targets due to their indispensable role in society, public safety, national security, and economic stability.
Notable incidents include the DP World Australia attack (November 2023) and the Colonial Pipeline ransomware attack (2021). Many OT/ICS systems in CI were built decades ago and are now vulnerable due to increasing interconnectivity.
Healthcare remains a top target due to the breadth of its attack surface and severe impact on patient health and safety, incurring high costs. In 2022, 89% of healthcare organizations experienced an average of 43 attacks, and it was the most common victim of third-party breaches.
Financial Services are experiencing increased attacks due to their interconnected nature, with ripple effects across global economies. The ICBC Financial Services ransomware attack (November 2023) disrupted the US Treasury market.
Manufacturing has been the top attacked industry for three consecutive years (2024), accounting for over a quarter of incidents within the top 10 attacked industries.
Retail and Logistics have become hotbeds for advanced persistent threat groups.
Defense Industrial Base (DIB) contractors and subcontractors are high-value targets.
Supply Chain Vulnerabilities are heavily exploited as an initial access method, with many breaches originating through trusted third-party vendors rather than direct attacks on victim organizations.
The number of software packages affected in known supply chain attacks increased from 700 in 2019 to over 185,000 in 2022, and Gartner predicts 45% of organizations worldwide will experience such attacks by 2025.
Financial Impact and Organizational Preparedness
Cyberattacks incur significant financial losses, including investigation, remediation, customer notifications, legal fees, and operational disruptions. Examples include LoanDepot ($27 million), CrowdStrike incident ($1 billion estimated global outage cost), MGM Resorts ($100 million), and U.S. government agencies ($18.8 billion in 2020).
Despite improving defenses, 7 out of 10 organizations still experienced an attack in the past year. CISOs and IT leaders are increasingly concerned about their ability to recover mission-critical data.
Over half (55%) of surveyed organizations have stalled or stopped digital transformation projects due to cybersecurity threats, hindering innovation.
Cybersecurity spending is increasing globally, with an average of 11% of IT budgets allocated to security.
The significant shortage of skilled cybersecurity professionals (3.5 million unfilled jobs predicted by 2025) remains a critical challenge, increasing demand for external services.
A notable portion of global organizations (one-third) are not taking the threat of cyberwarfare seriously, identifying as indifferent or unconcerned. Preventing nation-state attacks is often a low-ranked security element.
Social engineering tactics, like phishing and vishing, continue to be primary initial access methods and are expected to increase in sophistication due to AI.
How has AI impacted cyberattacks?
Artificial intelligence (AI) has significantly impacted cyberattacks by making them more sophisticated, faster, and accessible to a wider range of malicious actors.
Key impacts of AI on cyberattacks include:
Lowering the Entry Barrier:
AI reduces the technical skill required for cybercrime, enabling more individuals and groups to engage in malicious activities.
Enhancing Scale, Speed, and Effectiveness:
AI improves the efficiency and impact of existing attack methods, allowing for large-scale operations to be executed more rapidly.
Ransomware operators, for instance, are leveraging AI and automation to encrypt and exfiltrate data within hours of initial access.
Increased Sophistication of Social Engineering and Disinformation:
AI is expected to lead to a surge in large-scale phishing and disinformation campaigns. It enables threat actors to create more convincing and legitimate-sounding phishing emails, as well as highly realistic fake audio, video, and images (known as deepfakes), which increase the success rate of social engineering tactics.
Fueling Ransomware Evolution:
Advancements in AI are contributing to the increasing prevalence and sophistication of ransomware attacks, which remain a top global threat.
Potential for Kinetic Cyberweapon Enhancement:
AI can potentially enhance the capability of kinetic cyberweapons, shifting cyberattacks beyond espionage into more direct and impactful applications that could cause real-world physical harm or destruction.
Significant Financial Projections for Cybercrime:
