In an era where digital infrastructure powers everything from national economies to daily commutes, cyber attacks have emerged as the invisible weapons of the 21st century. From the disruptive WannaCry ransomware that paralyzed hospitals worldwide in 2017 to the sophisticated espionage campaigns attributed to nation-states like North Korea, the past decade has seen cyber threats evolve from opportunistic hacks to strategic assaults on critical systems.
As we mark the 10-year anniversary of some of the most infamous incidents, this article delves into the major cyber security attacks from 2015 to today, spotlighting key cases like the Sony Pictures breach, WannaCry, and North Korea’s relentless operations.
We’ll examine affected countries, financial tolls—including billions siphoned from banks—and the human cost. Amid rising threats, we’ll also highlight top cybersecurity firms leading the defense, the booming market size, and the latest disruptions, such as the ongoing EU airport attacks. This comprehensive resource draws on verified data to equip readers with actionable insights for navigating the current state of cybersecurity.
A Timeline of Devastation: Major Cyber Attacks Worldwide (2015–2025)
The period from 2015 to 2025 has witnessed an explosion in cyber incidents, with attacks surging 47% year-over-year in Q1 2025 alone, according to Check Point Research.
Ransomware, state-sponsored espionage, and supply-chain exploits dominate, affecting over 150 countries in some waves.
Global costs are staggering: Cybercrime is projected to inflict $10.5 trillion in damages by year’s end.
Below is a curated table of pivotal attacks, including countries impacted, attack medium (e.g., ransomware, malware), estimated financial losses, and loss of life (where applicable).
Data is aggregated from CSIS timelines, Wikipedia, and industry reports for transparency and depth.

Human impact is rare but severe in healthcare/energy sectors. Sources emphasize underreporting, with unreported incidents likely doubling figures.
Spotlight: Iconic Attacks and Their Ripples
The Sony Entertainment Attack: Hollywood’s Wake-Up Call
In November 2014— with effects lingering into 2015—the Guardians of Peace (GOP), linked to North Korea, unleashed destructive malware on Sony Pictures.
Triggered by the satirical film The Interview, the breach leaked 47,000+ employee records, unreleased movies, and executive emails, causing chaos. Primarily hitting the USA, it rippled to international partners in the UK and Japan. Losses topped $100 million in IT restoration and legal fees, with no direct deaths but profound reputational damage—co-chair Amy Pascal resigned.
This attack underscored nation-state motives beyond profit, blending cyber sabotage with geopolitical theater.
WannaCry: The Global Ransomware Pandemic
May 2017’s WannaCry, a North Korea-attributed worm exploiting Microsoft’s EternalBlue flaw, infected 200,000+ systems in 150 countries.
The UK’s NHS alone canceled 19,000 appointments, contributing to one indirect death.
Hardest hit: Russia (1% GDP dip), Taiwan, and Ukraine. Demands started at $300 in Bitcoin, but global losses hit $4 billion from downtime and recovery.
A British researcher’s “kill switch” halted its spread, but it exposed unpatched legacy systems’ dangers.
North Korea’s Cyber Arsenal: From Espionage to Heists
North Korea’s Lazarus Group has orchestrated over $3 billion in thefts since 2015, funding WMD programs amid sanctions.
Key ops: 2016 Bangladesh Bank ($81M via SWIFT), 2017 Bithumb ($7M crypto), and 2025 ByBit ($1.5B Ethereum).
Targets span 38 countries, including USA, South Korea, and UAE, via phishing and malware. No direct fatalities, but espionage (e.g., 2025 South Korean defense hacks) risks escalation.
Pyongyang’s ops blend financial gain with intelligence, making it a top global threat.
Bank Heists: The Silent Billions
Banks lost billions to cyber thefts, with North Korea alone siphoning $2B+ from 2015–2025.
Notable: 2015 Ecuador’s Banco del Austro ($12M), 2016 Vietnam’s Tien Phong ($1M), and 2024 Santander (30M records exposed, $ undisclosed).
SWIFT exploits enabled $1B attempts, like Bangladesh’s.
Cumulative global bank losses:
5B+indirecttheft,plus5B+ in direct theft, plus 5B+ in direct theft, plus trillions in fraud ripple effects.
The Latest Crisis: EU Airport Attacks (September 2025)
In a stark reminder of critical infrastructure vulnerabilities, a ransomware attack on Collins Aerospace’s MUSE software—used for check-ins and boarding—disrupted Europe’s busiest airports starting September 20, 2025.
Heathrow (UK), Brussels (Belgium), Berlin (Germany), and Dublin/Cork (Ireland) saw hundreds of cancellations and delays, stranding thousands.
The EU’s ENISA confirmed ransomware, with manual processes in place; full recovery may take days.
Losses: $50–100M+ from ops halts. This follows pro-Russian DDoS on Italian sites (including Milan airports) in February.
Aviation’s shared systems amplify risks—experts urge layered defenses like AI monitoring.

Drivers: AI threats (60% of IT pros fear AI malware), ransomware (126% rise in Q1 2025), and regulations like NIS2.
North America leads (34% share), but Asia-Pacific grows fastest.
The Current State of Cybersecurity: Trends, Threats, and a Call to Action
In 2025, cybersecurity is a high-stakes arms race: Attacks per org hit 1,925 weekly, up 47% YoY, with ransomware and AI-enhanced malware topping threats.
Key trends per Gartner/WEF:
- AI Dual-Edge: 60% of pros see AI malware as top risk, but it boosts detection (e.g., predictive analytics).
- Zero-Trust Dominance: Micro-segmentation essential amid supply-chain breaches (e.g., MOVEit).
- Quantum Looming: “Harvest now, decrypt later” stockpiling threatens encryption.
- Talent Crunch: 64% burnout risk; need for upskilling in AI/quantum.
- Ransomware Surge: 126% increase; double-extortion tactics target healthcare/municipalities.
- Supply-Chain Focus: 60% of execs fear third-party risks post-SolarWinds.
The state? Precarious yet proactive—25% see dramatic improvements, but 78% report gaps.
Organizations must invest in AI defenses, zero-trust, and training to counter $10.5T threats. As North Korea and Russia escalate, global cooperation (e.g., G7 norms) is vital. Stay vigilant: Patch, monitor, and collaborate.
The digital shadow war rages—will you fight back?
