The broader U. Russia has specialized in a massive information warfare campaign to influence U. North Korea, Iran and even terrorist groups have shown they, too, can do damage with a few keystrokes. On June 11, national security adviser John Bolton publicly stated that the U. The Pentagon has said the Times reporting was inaccurate but has not provided any clarification.

Later that month, Yahoo News disclosed that U. Cyber Command had hit Iranian military computers after Iran shot down a U. Cyber Command. Without effective cyber-defenses, more aggressive overseas operations could come back to bite the United States, experts warn. The Defense Science Board, meanwhile, has delivered a similar message, recommending in that a second U.

The report chillingly warned that doubts about U. A lack of cyber hygiene by just one employee or subcontractor of the government can be the entryway for a cyber break-in with strategic consequences. Although the Federal Communications Commission regulates commercial satellite infrastructure, it does not require applicants to demonstrate how they will cyber-harden their satellites, nor is there an overall federal policy or oversight agency concerned with securing commercial space assets.

The future of warfare will be defined by emerging technologies, including artificial intelligence AI , quantum-based cryptography, quantum computing and the evolution of space-based internet infrastructure. While the U. Nowhere is the cyberthreat more urgent than in the code-cracking ability of quantum computing for everything from routine public key e-commerce transactions to the most sophisticated American terrestrial, maritime and space-based defense encryption systems.

It is also the only post-quantum encryption option that is also fully homomorphic; that is, allowing computation on encrypted data without ever exposing that data. That feature is especially important when large data sets are involved, such as efforts to advance machine learning and artificial intelligence. In , the Pentagon elevated United States Cyber Command to the status of a full and independent unified combatant command, recognizing that cyberwarfare constitutes a unique theater of combat.

Cyberwarfare - Wikipedia

Last week, President Donald Trump launched U. It will be the responsibility of Congress to bridge the technological investment gap, while United States Cyber Command, U. Lawrence Sellin, Ph. There are hints of how a future cyberattack might cause even more disruption, or even physical destruction. In August , a piece of malware called Triton or Trisis triggered the shutdown of an oil refinery owned by the Saudi Arabian firm Petro Rabigh. Stealthily borking those systems could have led to potentially lethal accidents like an explosion or gas leak.

Iran, meanwhile, has over the past three years continued to periodically launch new waves of data destruction against targets in Saudi Arabia, Qatar, and the United Arab Emirates with revamped versions of the Shamoon wiper malware it used against Saudi Aramco. Aside from the prospect of attacks on safety systems and the looming possibility of another NotPetya-style worm, plenty of other nightmare hypotheticals continue to trouble the sleep of cyberwar wonks. They fear cyberattacks on water distribution systems, financial systems, gas pipelines, hospitals—perhaps even combined with a mass-casualty physical attack.

And after the blackout attacks in Ukraine, they warn that far more severe attacks on the electric grid are possible. Way back in , for instance, US researchers at Idaho National Laboratory showed in a demonstration that it was possible to destroy a tank-sized diesel generator with malicious code alone.

We explain what cyber warfare is and why you need to pay attention to the threats it poses

See the video of their demonstration below. Given that seemingly inexorable ramp-up of cyberwar's destructive potential, how do humans head off a chaotic future of endless, widespread digital conflict?

The most obvious answer is, of course, better cybersecurity: The owners of critical infrastructure across the government and private sector could certainly invest more in hardening their networks, separating vital systems from the internet wherever possible. But in cyberwar, as in the larger game of cybersecurity, the offense has the advantage: Don't expect any security technology to prevent all future cyberattacks.

Perhaps most importantly, critical infrastructure operators, government agencies, and companies need to focus on building resilient systems—ones whose backups and redundancies mean that they can bounce back quickly from serious cyberattacks. But cyberwar wonks also say that old-fashioned deterrence needs to play a role, too.

Countries need to face serious repercussions when they launch a cyberattack that violates some sort of red lines defining global norms of acceptable and unacceptable hacking activities. The Obama and Trump White Houses have taken the first steps to that kind of deterrence regime: The Obama administration indicted seven Iranian hackers for their roles in attacking US banks.

Mounting problem

Obama himself called out North Korea for its Sony cyberattack in a speech, and imposed new sanctions against the country. The Trump administration, for all its alleged friendliness toward Russian hackers, did eventually impose new sanctions against the country's intelligence officials in response to their NotPetya chaos and operations that penetrated the US power grid.

But those actions aren't enough, in part because the red lines they seek to enforce are still being drawn. For nearly a decade, cyberpolicy doves have been calling, largely in vain, for some sort of global treaty or convention that could establish rules for cyberwarfare. In their book Cyber War , Clarke and Knake proposed a Cyber War Limitation Treaty, which would ban first-use attacks on another country's critical infrastructure. More recently, Microsoft president Brad Smith has called for a Digital Geneva Convention that would prohibit cyberattacks on civilian targets.

  • Josh Corman, a former director of the Cyber Statecraft Initiative at the Atlantic Council think tank, has suggested a more limited agreement that he describes as a "cyber no-fly-zone" around hospitals, one that would essentially start the process of limiting cyberwarfare by making any life-threatening attack on medical facilities a war crime. But as the cyberwar arms race escalates, none of those cyberpeace initiatives has gained much traction.

    Critics point out that cyberattack motives are hard to define—a cyberespionage or reconnaissance intrusion can often look a lot like a cyberwar attack in progress—and determining the identities of the hackers responsible can be even harder. That so-called attribution problem hasn't stopped the US government from definitively naming the governments responsible for most serious attacks that affected Western targets over the last decade.

    US intelligence agencies can use both human sources and their own powerful hacking capabilities to find the culprits behind cyberattacks even when the public can't. More fundamentally, governments haven't been willing to sign on to cyberwar limitation agreements because they don't want to limit their own freedom to launch cyberattacks at their enemies.

    The Trump administration has only loosened the leash on Cyber Command, elevating its authority and freeing it up to launch preemptive attacks on enemy infrastructure. Until they do, the cyberwar machine will roll onward, with nothing less than the infrastructure of modern civilization in its destructive path.

    Entering risky territory

    But its blast radius was the entire world. What Israel's Strike on Hamas Hackers Means For Cyberwar The assault seems to be the first true example of a physical attack being used as a real-time response to digital aggression—another evolution of so-called "hybrid warfare.

    How Not To Prevent a Cyberwar With Russia As the Trump administration increasingly beats its cyberwar drum, some former national security officials and analysts warn that even threatening that sort of attack could do far more to escalate a coming cyberwar than to deter it. The Highly Dangerous 'Triton' Hackers Have Probed the US Grid Security analysts at the Electric Information Sharing and Analysis Center and the critical-infrastructure security firm Dragos tracked a group of sophisticated hackers carrying out broad scans of dozens of US power grid targets, apparently looking for entry points into their networks.

    They probed the networks of at least 20 different US electric system targets. Responding to them all with an equal sense of alarm is like conflating a street mugging with an intercontinental ballistic missile attack. Enjoyed this deep dive?
