All the truths and lies of Zero Day on Netflix, from worst to best

Netflix’s Zero Day places viewers in the middle of a massive cyberattack that paralyzes the United States. With Robert De Niro playing a former president investigating the attack, the series explores themes such as political intrigue, digital warfare, and the fragility of modern infrastructure. But how realistic is Zero Day from a cybersecurity perspective?

As experts in development and technological solutions at Q2BSTUDIO, we analyze the scenarios presented in the series to assess which threats are plausible and which are pure fiction. Below, we break down three threats that could occur in the real world and three that, at least for now, are cinematic exaggerations.

Three threats that could happen

The series depicts various attack vectors combined with severe consequences. Among the main methods are an attack on critical infrastructure with specialized malware and a supply chain offensive through fake versions of legitimate software.

When comparing these attacks to real events, we see there are worrying parallels.

Attack on critical infrastructure (Colonial Pipeline, 2021)

Cybercriminals targeting essential services is one of the most realistic threats in Zero Day. Attacks against power grids, water systems, and hospitals are not only possible but have already occurred. An example is the ransomware attack on Colonial Pipeline in 2021, which paralyzed one of the largest fuel pipelines in the U.S., causing fuel shortages and panic among citizens.

Malware with destructive capability (Stuxnet, 2010)

The series suggests that a nation could be attacked using malware specifically designed to sabotage industrial infrastructure. This type of threat has already influenced global geopolitics. A well-documented example is Stuxnet, a sophisticated cyberweapon that affected nuclear centrifuges in Iran. This malware operated as a worm capable of spreading through networks, affecting devices, and causing persistent hardware failures.

Supply chain attack (NotPetya, 2017)

Zero Day presents a situation where an attack spreads rapidly through interconnected systems. This is not only possible but has happened in real life. Supply chain attacks can infect thousands of organizations through a single compromised vendor. A notable case is the NotPetya attack in 2017, which spread via a compromised software update, causing billions of dollars in damages globally.

Three threats that are exaggerated

Netflix knows how to make its productions impactful, but Zero Day also dramatizes certain situations beyond reality.

Instant and simultaneous system collapse

In the series, the cyberattack seems to bring everything down at once: financial markets, emergency services, and transportation. Although coordinated attacks exist, in real life cyberattacks do not spread with such immediate precision. Attacks like NotPetya or SolarWinds took time to propagate, and the responses from affected organizations varied in speed and effectiveness.

Total control with just a few keystrokes

Zero Day falls into the typical Hollywood cliché of a hacker typing lines of code in the dark and bringing down entire systems in seconds. In reality, a cyberattack requires weeks or months of preparation, including social engineering, vulnerability research, and evasion of detection. It is not as easy as pressing a few keys and watching the world burn.

The unstoppable supervirus

The series depicts a cyberattack that is supposedly impossible to stop. While highly sophisticated malware exists, there are always ways to counter it through endpoint protection, network segmentation, and manual controls. No malware is completely indestructible, and countermeasures can always be developed.

Could fiction become reality?

Although Zero Day exaggerates several situations, some of its ideas could become viable in the future. The advancement of AI-based tools, attack automation, and autonomous malware are trends moving in that direction. At Q2BSTUDIO, we constantly work on risk analysis and the development of technological solutions to protect companies and organizations from future cyber threats.

For example, the use of AI is already facilitating phishing campaigns with personalized content, reducing the effort required by attackers. Additionally, with the growth of state-sponsored cyberwarfare, the line between fiction and reality is becoming increasingly blurred.

Conclusion

The series Zero Day may be a dramatization of cybersecurity, but it sends a clear message: our digital infrastructure is vulnerable. Although we may not see a cinematic virus that wipes out everything, threats like ransomware, attacks on critical infrastructure, and AI-driven cybercrime are unsettlingly real.

At Q2BSTUDIO, as experts in software development and technological solutions, we believe that the best defense is education and prevention. Learning from past attacks and being prepared for new threats is key to mitigating risks in an increasingly digital world.
