From Viruses to Deepfakes: The Real Evolution of Cybersecurity

The beginning: from Creeper to the first worms

The first computer virus wasn’t a devastating attack, but a curiosity. In 1971, Creeper displayed the message “I’m the Creeper, catch me if you can” on mainframes. It didn’t delete data or demand money: it was an experiment.

That experiment, however, hinted that software could become a weapon. What began as a game would eventually trigger a cycle of crime, war, and digital manipulation.

The 1990s and 2000s: the professionalization of crime

With the expansion of the Internet in the 1990s came worms like Morris Worm or ILOVEYOU, capable of collapsing entire networks.

In the 2000s, organized crime understood the economic potential: email scams, mass phishing, and the first ransomware variants (AIDS Trojan, Gpcode). An FBI report in 2005 already estimated annual losses of more than $67 million due to cyber fraud.

The decade of nation-states: Stuxnet and covert operations

In 2010, the discovery of Stuxnet marked a turning point. It was the first malware designed with a clear geopolitical goal: sabotaging nuclear centrifuges in Iran. Its existence proved that cyberweapons could alter world diplomacy.

Since then, attacks like NotPetya (2017) —attributed to state actors and causing damages of more than $10 billion— demonstrated that cyber conflicts have global economic impact.

The 2020s: deepfakes and perception manipulation

This decade brings a different challenge: it’s no longer just about attacking systems, but about attacking human perception.

In 2020, a British bank lost $243,000 after employees received a call from a “director” whose voice was in fact AI-cloned. Today, deepfakes are used in political campaigns, disinformation, and corporate fraud.

Cybersecurity is no longer just a problem of machines: it now requires training people to doubt what they see and hear.

Supply chain: the invisible Achilles’ heel

Organizations often protect their perimeter but forget they rely on hundreds of providers.

The 2020 SolarWinds case made it clear: compromising a management software allowed infiltration into government agencies and major corporations worldwide. In 2023, MOVEit repeated history, exposing data of over 60 million people through a vulnerability in a transfer tool.

The reality is that our infrastructure depends on chains where the weakest link is often invisible.

Artificial intelligence: defense and attack

AI accelerates threat detection but also multiplies them.

Today, models exist that generate phishing without grammatical errors, tailored to the victim’s style. Malware has even been detected retraining itself to evade antivirus after each failed attempt. What once required months of engineering can now be automated in minutes.

The quantum horizon

Though still experimental, quantum computing poses a real risk: current cryptography (RSA, ECC) could be broken in hours.

That’s why agencies like NIST are already working on post-quantum cryptography standards. The immediate risk isn’t that someone can decrypt communications today, but that encrypted data may be stored, waiting to be broken tomorrow (“harvest now, decrypt later”).

From technical to cultural

The major shift is that cybersecurity is no longer only technical, but cultural.

Checking a compliance box won’t stop a convincing deepfake or protect against a vulnerable supplier. Security also requires critical thinking: employees trained to doubt the plausible, and companies aware that their walls depend on external foundations.

Conclusion: the mind as the target

The greatest exploit of this decade is not in machines, but in the human mind.

We can reinforce firewalls and update algorithms, but if we stop questioning what we see and believe, any defense will be insufficient. The cybersecurity of the future will demand not only cryptography and machine learning, but also critical education and a culture of intelligent distrust.
