The word war often evokes images of bombs, guns, and mass destruction. But what if that perception is outdated? Today, a new kind of warfare, silent, digital, and arguably just as devastating, dominates our world. Cybersecurity now stands at the front line of national defense, corporate survival, and personal safety. As our reliance on technology grows, so does the sophistication of cyber threats.

History is vital as it allows us to learn from the mistakes of past generations. In the same way, future generations will look to us, the “test bunnies” of the digital age. We are the first to rely so heavily on technology without fully understanding its long-term effects on safety, mental well-being, and even physical health.

Everything from banking to global transportation to national security and personal data is now tied to interconnected systems. Therefore, the question needs to be asked – what happens when those systems fail, or worse when they are deliberately compromised? As the first generation navigating this technological era, how do we protect ourselves whilst ensuring future generations learn from our experiences? More importantly, how will we seek to safeguard ourselves today from the potential dangers that lie ahead.

A digital battlefield

In February 2025, British bank Barclays suffered a wide-scale system outage, leaving customers unable to access their accounts for an entire day, and for some even longer. While this particular incident was not a cyberattack, it highlighted a critical vulnerability, our reliance on digital financial systems. If a well-coordinated attack were to target multiple banks simultaneously, entire economies could be brought to a standstill. The stakes are even higher when government databases, healthcare systems, or military intelligence are infiltrated, posing existential threats to individuals and nations alike.

Hackers: the new cybersecurity guardians?

As a way to counteract threats, governments and big corporations are now recruiting those who were once seen as posing risk, hackers. Many of the elite cybersecurity specialists today were once notorious cybercriminals. With invaluable expertise, they are a staple piece to the cyber army in identifying loopholes and protecting digital assets.

There have been many instances where hackers infiltrated government and corporate systems for the thrill of it, often alerting organizations to their overlooked vulnerabilities. Known as “white hat” hackers, there have been some cases where these ethical hackers receive a formal thank you letter or even a job offer from the very institutions they breached. The battle between security teams and hackers has become a neck-and-neck race, with each side constantly evolving to outwit one another.

The silent war: the cybersecurity battlefield

In an era dominated by artificial intelligence and digital tools, sensitive information is unknowingly exposed every day. Whether it be people innocently passing confidential contracts into AI tools such as ChatGPT for rapid edits or businesses using AI to refine corporate documents, this data doesn’t just disappear out of thin air, it’s stored. So, we have to ask ourselves, what would happen if these AI systems were to be hacked? Something as innocent as using ChatGPT for guidance could turn into a disastrous breach, exposing classified documents, trade secrets, and personal data.

Beyond individual risks, every nation is engaged in an invisible war, one where information is the most powerful weapon. It is no longer the case of solely competing on military strength, but also on digital intelligence. Countries deploy their top hackers to infiltrate rival systems, an attack just as strategic and destructive as warfare on land but carried out in silence. Classified files, covert operations, and internal corruption will all be exposed. Cyberattacks can destroy national security, and economies and completely dismantle infrastructure, all without one missile being fired.

Despite this ever-growing threat, global defense budgets remain primarily focused on physical warfare. For example, in the UK, billions are spent every year on military forces and weapons, yet in comparison, cybersecurity remains underfunded. In a world where practically every aspect of life is landscaped around being digital, investing in cyber defense is no longer an option, it is imperative. Without it, the next world war may be missing bombs and guns but with keystrokes and code.

The rise of digital mercenaries

One of the most unnerving developments in cyber warfare is the hacking of GPS systems. Reports emerged in 2019 that commercial ships in the Black Sea experienced GPS spoofing attacks, misleading vessels about their accurate locations. Likewise, in 2021, a cyberattack on Iran’s railway system caused mass disruption by manipulating GPS-based scheduling systems. Correspondingly at risk are aviation navigation systems, with instances such as the 2018 suspected GPS interference at Manila’s airport creating confusion for pilots. If such incidents continue, they could result in wide-scale disasters with fatal consequences.

A future where cyberwar is the norm

As the next generation becomes more technologically capable, cybersecurity threats will become at a rate of advancement that we can not yet comprehend. Coding could become a mandatory skill taught in schools, just as math is a compulsory learning skill in all schools now. We are still only at the very beginning of the technology boom. In the next 50-plus years, incomprehensible innovations will redefine the world. With the advancements comes an urgent need for new cybersecurity strategies that are just as, or if not more, revolutionary. It is now in the hands of governments and major corporations to prepare for this digital battlefield. The age of cyber warfare is here, and it is only those who adapt that will survive as we move towards a future where “guns don’t kill people, computers do.”
