Experts discuss Netflix miniseries Zero Day cyber themes

Netflix's new miniseries, "Zero Day," featuring Robert De Niro as a former United States president grappling with the aftermath of a massive cyberattack, has sparked a flurry of commentary among cybersecurity experts. Reflecting upon the series' depiction of a nationwide digital onslaught, professionals have lauded and critiqued its portrayal of cyber warfare.

James McQuiggan, a Security Awareness Advocate at KnowBe4, commends the series for raising awareness about the potential vulnerabilities of critical infrastructure, such as energy grids, transportation, and telecommunications, to cyberattacks. McQuiggan noted that nation-states or advanced persistent threats accessing systems long-term is a legitimate concern. However, he critiques the notion of immediate attribution of cyber attacks, explaining that tracing the origins of such attacks can take extensive time due to hackers' use of proxies and other obfuscation tactics.

Martin Jartelius, CISO at Outpost24, concurs that the series overestimates the scope of cyber threats. He explains that the simultaneous disruption of multiple industries, as depicted in "Zero Day," is highly improbable. He highlights that malware needs to be specifically tailored and that the UK's robust industrial control systems often operate on isolated networks, making remote infiltration challenging without insider assistance.

Chris Hauk, Consumer Privacy Champion at Pixel Privacy, regards "Zero Day" as a captivating drama that paints cyber threats as looming possibilities. However, its portrayal of a broad-scale attack remains speculative. Hauk appreciates the series' role in stirring public consciousness about cyber threats, albeit its somewhat hyperbolic representation.

Despite these critical observations, cybersecurity experts view the series as helpful in increasing vigilance and cyber preparedness. Brian Higgins from Comparitech found the fictional scenario akin to other exaggerated Hollywood depictions, suggesting it highlights deeper themes of power and corruption rather than serving as an accurate cybersecurity blueprint.

Roger Grimes, Data-Driven Defense Evangelist at KnowBe4, acknowledges that while cybersecurity concepts' terminology and general use were handled well, the feasibility of such widespread disruptions happening all at once was questionable. He pointed out that a single type of malware impacting an entire system is unlikely, as multiple targeted approaches would be required. Grimes also discusses the misuse of the 'zero-day' concept in the series, noting that such vulnerabilities are often known to specific entities rather than entirely undiscovered.

Overall, "Zero Day" generates interest and discussion about the risks inherent in our increasingly digital world. The experts unanimously agree that while the miniseries takes artistic liberties, it serves an important purpose. It underscores the need for governments, businesses, and individuals to remain vigilant and improve safeguards against potential cyber threats. The series also prompts discussions about the geopolitical dimensions of cyber warfare and the intricate balance of power it entails.

"Zero Day" may not capture the nuances of real-world cyber operations, but it serves as a reminder of our vulnerabilities. It urges stakeholders across various sectors to consider bolstering defences to mitigate the risks posed by such digital threats. As cybersecurity remains a critical aspect of global security, such portrayals play a pivotal role in shaping public and political discourse.
