Critical Infrastructure: Stop Whistling Past the Cyber Graveyard

An open letter to former colleagues in Homeland Security, peers in private sector cybersecurity firms, those who own and operate critical systems, academics, and politicians.

I woke up to a cyberattack double-whammy that frankly made me want to go straight back to bed.

First, the Department of Homeland Security and the FBI issued an alert about the Russian government's targeting of US critical infrastructure — nuclear power plants, chemical plants, heavy manufacturing facilities, and so on. The joint alert was an extraordinary and unprecedented move by two agencies that traditionally have avoided pointing the finger at nation-state actors. From my time as the founding director of the United States Computer Emergency Readiness Team (US-CERT), I can say this is highly unusual.

As if that were not enough, the New York Times published a lengthy analysis of a cyberattack on a Saudi petrochemical plant that took place in the summer of 2017. Though investigators have yet to publish their findings as to who was behind the attack and what the attackers hoped to achieve, cyber experts speaking on the condition of anonymity told the Times that they believe the attack was intended to cause an explosion and kill or injure hundreds of people.

These scenarios may read like a summary of the latest must-see episode from Homeland or the latest superhero flick, but they're not fiction — far from it. They reflect the stark and sobering reality of living in our digital-everything world. The fact that they are surprising to anybody is the most shocking (and some might say terrifying) thing of all. According to a study of the oil and gas industry by the Ponemon Institute, 68% of respondents report at least one security compromise. As recently as last year, the Department of Energy reported that the American electrical grid was in "imminent danger" from cyberattacks that are "growing more frequent and sophisticated."

The signs are all around us and they're multiplying and growing more strident. At best, the string of cyberattacks on petrochemical plants in Saudi Arabia is an alarming reminder of the threats facing critical infrastructure everywhere. At worst, they're a stark warning, if not a promise, of what's to come.

Let me put this another way: all of the hand-wringing and face-palming in Congress and in the media over the Equifax breach, which jeopardized the personal information of roughly 148 million Americans, will look like a walk in the park compared to what happens should a US energy facility be successfully attacked. And with reason. It's the difference between damages that can be more easily dismissed as a nuisance — a compromised driver's license number, for example — versus those with the potential to wreak widespread havoc in our communities. We're talking about the kind of cyberattack that jumps the digital divide and does physical damage with the intent to injure or kill people.

Securing decades-old power plants and manufacturing facilities that were deemed safe from cyberattack precisely because they were never designed to be connected to digital devices is incredibly complex, and I acknowledge that. But the fact is that these plants were designed for the old-school way of doing things, not for a digital world brimming with smart, connected heaters, window shades, cars, and phones.

We must view these attacks as an urgent call to change the way we handle the threats targeting the world's most valuable and vulnerable systems. Otherwise, the next story won't be about what could have happened. It'll be about the real-world consequences of what did happen. We'll be looking in the rearview mirror asking ourselves why we, collectively, were asleep at the proverbial wheel.

Securing the critical infrastructure that powers our modern lives has to be made a global priority. This is a sacred trust shared by both private and public sectors. This is an all-hands effort for cybersecurity — my former colleagues in Homeland Security, my peers in private sector cybersecurity firms, those who own and operate critical systems, academics, and politicians — to come together to address this issue now. We can't solve the security challenges facing these delicate, mission-critical systems by working in isolation. Industry experts and government agencies around the world need to work together to develop modern standards, processes, and regulations to address today's modern threat landscape. Let's start by protecting the systems that matter most.

Progress, 13 years later
As someone that started working to secure ICS/OT for a national lab back in 2006, there has been tremendous progress in the space, albeit, at a slow pace. Up until recently, companies that developed products to secure ICS/OT didn't have a market. There were no buyers; no one responsible for ICS/OT security; hence the reason that the government and national labs weighed in to the fray. We've now become self aware, the market has matierialized and we're finally holding conversations that I only dreamed of 13 years ago. The attack surface for ICS/OT has expanded rapidly during that timeframe and our technologies just aren't quite there to protect them, yet. What to do in light of that? One, know what you have - identify your key ICS/OT cyber terrain. Two, operate as if you're ICS/OT is compromised already. Three, prioritze your risk and be sure to include safety/all hazards into your analysis, not just cyber. As Amit correctly noted, "It'll be about the real-world consequences".

CVE-2020-15208
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, when determining the common dimension size of two tensors, TFLite uses a `DCHECK` which is no-op outside of debug compilation modes. Since the function always returns the dimension of the first tensor, malicious attackers can ...
CVE-2020-15209
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, a crafted TFLite model can force a node to have as input a tensor backed by a `nullptr` buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one....
CVE-2020-15210
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, if a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. We have patched the issue in d58c96946b and ...
CVE-2020-15211
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices f...
CVE-2020-15212
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger writes outside of bounds of heap allocated buffers by inserting negative elements in the segment ids tensor. Users having access to `segment_ids_data` can alter `output_index` and then write to outside of `outpu...
