Drones are growing in popularity with consumers, agriculture, for delivery and for government use. Some of the first practical and commercial use of aerial drones includes data gathering in the form of geographical mapping, general reconnaissance, rescue surveillance, video and photography, and other such applications. Agricultural companies were some of the first to begin wide use of drones to collect data related to crop yields, soil quality, nutrient measurements, rainfall, and other such applications, even prior to the FAA lifting a usage ban in 2014. Now in more ubiquitous and acceptable use, large carrier companies are about to widely implement their usage in a way long envisioned: for transportation and physical delivery of consumer goods.  

For example, Pizza Hut is trying out a new approach for delivery. The Wall Street Journal reported that Pizza Hut Israel will test out sending drones to drop multiple orders at government-approved landing zones where delivery drivers will collect orders and take them to customers. Other companies, like Wingcopter, are doing great things with drones as well including partnering with Unicef for COVID-19 vaccine delivery to remote areas. 

With all of the positive things that drones can accomplish, there also comes the need for assessing security of the devices themselves, or the threats they can directly impose. Bad actors could exploit a number of things and cause issues.

For starters, exploiting a drone directly threatens the confidentiality of the data it carries or has gathered. That data can be used for a multitude of purposes or further exploits including outright theft and use of data for espionage, sale of data if someone else finds value in it, or use in further exploits. 

There is also the threat to the integrity of the data, which can beget more nefarious and resource-impacting exploits. For instance, if I can manipulate agricultural data then I have potentially threatened at least a portion of the food supply, or at least the bottom line of a food supplier. Naturally the threat to availability of data (e.g., if the data is deleted before it can be properly used), it can create potential hardships or at least affect outcome efficiencies that might be lost.

There is the threat of commodity theft or supply disruption, given that drones are likely to become part of the consumer transportation economy. Opportunity works both ways, and undoubtedly bad actors will make attempts, in addition to pilfering goods directly from the drones, to hijack and redirect their intended destination, or otherwise bring them down through other interfering means. The scariest use of drones, in my opinion, is their weaponization either as individual units or, for maximum damage and effect, in a swarm.

Drones are also being used for more close-quarter, precision cyber attacks against devices that might be more physically removed in terms of access from the outside. Whereas a bad actor may have been able to scan for active wif-fi networks from a more openly-accessible location outside the facility, attenuation issues often made it difficult to proceed beyond detection. This has been a practice known as war-driving. Now, with the use of drones, proximity is no longer an obstacle to scan and attempt penetration of a wi-fi network. This practice, referred to by some as “war flying,” uses the drone more directly as an offensive platform to perform a cyberattack. In fact, there are even special toolkits with hacking programs available on the web that are optimized for use by drones.

It begs the question: what can I do about it? The last part about weaponization is almost too much to think about, though it should not be lost on anyone that drones, as well as other IOT devices, have made more of a direct impact on life/safety than almost anything else in the cyber realm (short of outright cyber warfare). One of the first things to consider as an organization that uses or will use drones is your supplier or manufacturer. It has always been feared that some nation states may have tampered with certain electronic components, chips or products they manufacture, in order to facilitate at best some level of espionage, or at worst direct physical sabotage. In fact, an executive order was issued in January of this year encouraging entities of the U.S. government to abstain from procuring and using drones manufactured by companies on the blacklist maintained by the Commerce Department.  

The tentacles of this executive order are only starting to reach out, concurrently as the likes of Amazon, UPS, FedEx and other major carriers won FAA approval in late 2020 to employ drones “over people” and at night. Here’s the rub…it doesn’t take a nation state altering drones of its own manufacturing devise, when they can affect the source of electronics and other “coded” components in countries not on the blacklist. And if nation actors can do it, so can other actors with the right support, patience and time.

With the increase of bad actors going for the source, the ways that they can access it are growing as well. In the recent cyber attacks that affected many companies, the source (such as the SolarWinds breach) unknowingly infected the other companies. Bad actors are always looking for new opportunities to get ahead and the increase of drone usage may be their next target. 

Almost comically, though proven to be effective, the use of predatory birds to counter the drone threat has been used by the military. Certainly most companies are likely keen on maintaining a flock of eagles or hawks for this purpose, so other defense mechanisms such as lasers, net cannons, or jammers will continue to gain market share over time. The reality is that there is not a uniform mitigation strategy or set of best practices to mitigate the threats posed by drones at present. Perhaps there will be one day, but the reality is that the drone is simply a delivery mechanism that can be used for malicious purposes; another means of conveyance for bad actors to commit malfeasance. Aside from security of the hard-coded components, it is largely a physical security issue. But we all know that poor physical security can undermine even the strongest level of cyber security, so don’t expect that this will continue to be a fringe activity.  Drones are omnipresent these days, and now we should expect to see them more often in the normal course of our daily lives. Sooner or later there will be a reckoning, and I believe it will be the cybersecurity industry that leads the way in drone defense, one way or another.

As a Managed Detection and Response (MDR) service, we actively hunt all data that we have access to, including data from drones and autonomous vehicles. If there is a threat, we are able to detect and mitigate the incident working with our customers to restore operations to normal. Stopping the bad actor at their source is the best defense.
