Scenarios for crime and terrorist attacks using the internet of things


The Internet of Things is a paradigm in which everyday items are connected to the internet and share information with other devices. This new paradigm is rapidly becoming a reality in the developed world, and while it holds an immensely positive potential, it also means that criminals and terrorists would be able to influence the physical world from the comfort of their homes. We can expect that hackers, ransomwares, viruses, spywares and many of the other woes of the internet today will migrate to the internet of things as well. In this research we used General Morphological Analysis and brought together fifty experts on an online platform to develop novel scenarios about the crimes and terrorist acts of the future. The experts developed 21 scenarios, which were then ranked according to their plausibility. We provide a brief description of every scenario, and focus particularly on the four most plausible ones: blackmailing by connecting to smart homes, gaining insider information from wearable devices and using it for financial gains, assaulting a smart city through the internet, and performing sex crimes via connected items in the smart home.


The Internet of Things (IoT) is a paradigm under which common objects are equipped with sensing, information processing and communication capabilities, and communicate with each other over the internet [1]. While many digital devices like desktop and laptop computers and smartphones are already connected to the internet, the core idea of the IoT is to expand this capability for networking to practically every object which we use: from tiles on the pavement to cars on the street, and from the kitchen sink and smoke detector in our houses right down to the lowly toothbrush and hair comb.

The Internet of Things (IoT) is expected to proliferate widely in the coming decade. According to CompTIA, about 50.1 billion objects will be connected to the IoT by 2020 [2]. Other notable forecasts by respected firms like Morgan Stanley and Huawei state that we will see 75 billion and 100 billion networked devices by 2020 [3] and 2025, respectively [4]. It seems clear that the IoT will become a definite part of our lives in the future, with all the benefits it can confer on us – as well as the risks.

It is common knowledge that criminals and terrorists are early adopters of new technologies [5] – largely because the conventional technologies are already well-defended and highly regulated. Many IT firms are concerned that the IoT is a “security disaster waiting to happen” [2], but few know exactly what to expect, as criminals and terrorists are making their first forays into the open sea of IoT-enabled crime and terror attacks. Security breaches from cloud-based devices are constantly on the rise (with a 152% rise in just 1 year between 2014 and 2015 [6]). The number of cyber-attacks is rising precipitously as well, and since in the future many objects and machinery will be connected to the IoT, the implications are that cyber-attacks can be translated directly from the virtual to the physical world. Terrorists will be able to profoundly impact the physical world in other countries, without actually getting up from their chair in front of the computer.

The future of the IoT means that security forces must prepare themselves for new kinds of crime and terrorist attacks. To do that, in this study we have worked with fifty experts on Wikistrat’s crowdsourcing platform, and together we have developed a series of scenarios that describe future potential crime and terrorist attacks that utilize and rely on the IoT. The scenarios were developed using General Morphological Analysis (GMA), and were then graded by the experts according to their plausibility. The most plausible scenarios are described in length in this paper, along with lessons and insights about the usability of Wikistrat’s platform for collaborative thinking and scenario development.

Scenario development and morphological analysis

There are many methods used to distinguish between different categories of scenarios and scenario development processes [79]. In their seminal review of the field, Bishop, Hines and Collins have identified eight general categories of scenario techniques, and more than 23 different techniques used to develop scenarios [10].

Out of all of those, we have chosen to use General Morphological Analysis (GMA) as the technique with which to develop the scenarios. Bishop et al. describe Morphological Analysis as a technique that is especially relevant when dealing with dimensions of uncertainty. In their words: “(…)we have to deal with systems in chaos and/or emergent states that are inherently unpredictable” [10].

It therefore seems that GMA is particularly suitable to analyze the possible uses terrorists and criminals will have for the IoT.

The original concept of GMA was born in the mind of astronomer Fritz Zwicky in 1948 [11]. The method was later utilized widely and disseminated by Tom Ritchey of the Swedish Morphological Society. Ritchey has also added layers of sophistication and capabilities to the method by developing a computerized system for automated analysis and cross-consistency assessment (CCA) functions [1214]. GMA has been widely used in many different fields, from design to policy analysis [15]. In security and defense studies, in particular, it has been used recently to evaluate preparedness for HAZMAT accidents [16], to create threat and sabotage scenarios for nuclear facilities [17], and to outline a framework for proactive risk management in civil aviation [18].

Morphological analysis is conducted by identifying several categories of factors that influence the final scenario, and which are grouped into different categories called parameters. The factors are then cross-matched to produce kernels (as Bishop et al. eloquently put it) for scenarios that can then be more fully developed.

We have made use of GMA on Wikistrat’s crowdsourcing platform, to produce novel scenarios describing how criminals and terrorists could use the IoT in the near future to accomplish acts of crimes and terror. Fifty experts in cyber-security and other fields have meshed together different factors from three categories: targets, motives, and methods. They then ranked each factor according to its likelihood or impact. A typological field was created containing 9,660 combinations of factors – each of which being the basis for a scenario to be developed. We have also expanded on three combinations of high impact and high likelihood, and on three combinations of high impact but low likelihood (the ‘wild cards’) and developed scenarios around them, which were then reflected upon, edited in a highly collaborative crowdsourced fashion, finalized and graded according to their plausibility.

Wikistrat’s crowdsourcing platform

Wikistrat is a crowdsourcing consulting company that utilizes the ‘wisdom of experts’ on a crowdsourcing online platform. The platform is similar in style and looks to Wikipedia, and enables experts to easily discuss issues with each other, collaborate on scenario development and vote on various questions. The participants can openly share information and knowledge with each other, correct each other’s mistakes and work together to improve their ideas [19]. These properties make Wikistrat’s platform ideal for conducting brainstorming and developing ideas and scenarios in large groups of dozens of experts.

The platform has been described in at least one review as facilitating “faster synthesis and analysis amongst analyst teams” and enabling multiple teams to work in parallel while still being exposed to each other’s work and benefiting from it [20].

Wikistrat has a community of over 2,500 experts and analysts that come from a variety of backgrounds, and the company verifies each expert’s background before he or she is allowed to enter the community and take part in ongoing research. For the current research, we sent an invitation to Wikistrat’s community, and the experts self-selected themselves by taking part in the discussions. Altogether we had fifty experts in the discussions and voting sessions. Out of those fifty, 33 had knowledge and background in security, cyber-security or antiterrorism. The others had various backgrounds, mostly in the social sciences. We believe that this diversity is crucial in any effort to create scenarios that combine both understanding of novel technologies like the IoT, and their potential impact on nations, governments and citizens.


We conducted the research in the following three steps:

  1. 1.

    Factors Identification: we identified 6–9 factors in each category of methods, motives or targets.

  2. 2.

    Scenario Development: the experts were asked to match together any three of the factors – one from each category – and to develop scenarios that depict ways in which criminals and terrorists utilize the IoT for their purposes.

  3. 3.

    Determining Plausibility: the experts were asked to grade each scenario according to its plausibility.

Each step is presented in detail in the following sections.

First step: identifying factors

The factors were identified in previous research (unpublished as yet) by the same experts, and ranked according to their impact and likelihood. We selected between six and nine factors in each category, and those factors were presented to the experts in the second step.

Second step: scenario development

The factors were presented to the experts, who were then asked to match them together and develop plausible scenarios for future crime and terrorist acts relying on the IoT. The experts were encouraged to work together, to give feedback about each other’s scenarios and even ‘barge in’ and rewrite scenarios written by their colleagues. This part of the research only took 4 days – a time that has been found to be optimal in similar research conducted in the past on Wikistrat’s platform, to ensure that the experts’ attention is kept at a maximum.

Third step: determining plausibility

The scenarios were ranked by the experts according to their plausibility. The final plausibility score for each scenario was calculated according to the following formula –

$$ Plausibility\; Score=\frac{\left(1*{N}_1\right)+\left(2*{N}_2\right)+\left(3*{N}_3\right)}{N_{all}} $$

With N1, N2, N3 being the numbers of participants who voted for low, medium or high plausibility, respectively. Nall is the total number of participants who took part in the rankings for each scenario.

Results and discussion

Factors identification

A total of nine factors in the motives category, eight factors in the targets category and five factors in the methods category were selected for the next phase (see Table 1). Since some of the participants were not experts in cyber-security and did not understand some of the methods suggested by their peers, we added a sixth generic method – “Genius Hacker” – basically a ‘joker’ that does not have to be explained any further. The analysts could use that method as a generic catchphrase to describe a crime or a terrorist act which they could not explain otherwise how it would be performed.

Scenario development

The experts worked together to create 24 scenarios. Three of the scenarios ended up being redundant, and some of their ideas were combined with other similar scenarios, for a final count of 21 finished scenarios.

The experts provided constant feedback for each other’s work. Each scenario received anywhere between zero and ten comments, with the median number of comments for each scenario being 4. The median number of revisions for each scenario, including revisions by the original author and by other participants, was 3. These results indicate that the experts were indeed involved in each other’s work, consulted each other, provided feedback and made corrections in their writings. It is also likely that some experts exchanged private messages on the platform concerning the scenarios, but such private discussions were not monitored for obvious reasons.

Determining plausibility

Following the scenario development process, the experts ranked each scenario according to its perceived plausibility. The final results appear in Table 2, along with a brief description of each scenario.

In-depth scenario analysis

While an in-depth analysis of all the scenarios had been conducted as part of the research, this paper’s constraints allow us only to focus on the four most plausible scenarios, present evidence for their feasibility, and explain their significance.

Smart home blackmailing

In this scenario, the IoT appliances in smart homes allowed criminal hackers to spy on the lives of private citizens and blackmail them using sensitive material. Such crimes seem highly likely in light of the common use of ransomware in the present, especially ones tapping into webcams [21]. Similar ransomware that could tap into the smart house appliances and record the victims could be used to blackmail people in the near future as well.

This scenario is based on the fact that smart homes are rapidly turning from an abstract concept to a reality. IoT devices can be found everywhere, and include smart door locks,Footnote 1 virtual assistants like Amazon Echo,Footnote 2 smart baby monitors and security cameras,Footnote 3 smart thermostats,Footnote 4 and even smart grillsFootnote 5 and household robots.Footnote 6 All of the above can be connected to the internet and be controlled by their owners via dedicated apps or platforms. They can also be hacked, as has already been demonstrated in 2016, when inherent flaws in Samsung Smart Home platform allowed hackers to control people’s light bulbs and even door locks with ease [22]. By the time the flaw was discovered, the system was already installed in at least a hundred thousand homes (according to the number of downloads of the app in the Google Play Store).Footnote 7

Insider information

In this scenario, a wealthy business man’s wearable devices are hacked by criminals, and used to gather information about that person’s financial decisions. Criminals and crime organizations that manage to conduct such attacks successfully could remain unknown and unseen for a long time, while getting consistently richer by means of their insider information.

This scenario seems especially likely since sophisticated emerging technologies like wearable devices and smart home appliances and platforms are often being used by the wealthy before they become everyday utilities. As a result, these technologies are not as secure as they should be in their early stages. Wealthy individuals could easily find themselves under surveillance by criminals who will break into their IoT devices and track and record their every movement and doings.

Smart city under attack

The participants highlighted two potential highly-plausible scenarios relating to cyber-attacks on smart cities:

  • Cyber-attack as a precursor to a physical attack: a highly capable terrorist group could remotely conduct a cyber-attack to essentially shut down or disrupt the ongoing affairs of a city. The cyber-attack would then enable and be followed by a more conventional attack enacted by terrorists with guns or explosives.

  • Cyber-hacktivists disrupting city functions: cyber-hacktivists would shut down or disrupt some key infrastructure units in a smart city, leading to political embarrassment, economic damage and potentially even loss of human lives. Such incidents can be particularly expected during an important and highly visible political, sporting or economics event stage in the city.

Additionally, the analysts indicated that two of the top-impact targets for shutting down a smart city would be the traffic management systems and the electrical grid, which includes an actual disruption of the workings of nuclear and energy power plants.

Smart cities are beginning to form around the world. Nicolas Reys, in his report for the ControlRisks consultancy, explains that they are the natural outcome of three technologies being combined together: cheap logic controllers, a large number of sensors spread all over the city, and a network that connects them all together. Several cities are well on their way towards becoming ‘smart’, including Amsterdam, Barcelona, Santa Cruz and Stockholm [23].

Sex and the smart home

Sex crimes could be enacted by relying on the IoT. Examples for IoT-based sex crimes, outlined by the analysts, include –

  • Sexual assault: by gathering information from smart home appliances about the victim’s whereabouts and habits, the attacker could know exactly when and where to strike.

  • Obscenity (communicating sexual meaning to the victim): by using IoT speakers, the offender could broadcast obscene sexual messages to people, including children (as may already have happened when hackers took control of IoT-connected baby monitors and used them to chat with babies in their cribs) [24].

  • Exhibitionism (displaying sexual content to a victim for pleasure): similarly to obscenity, the offender could use connected speakers and/or TV sets in other people’s houses to enact an exhibitionism crime on a scale unrealized before.

  • Voyeurism (observing others for a sexual motive): by hacking into the various appliances in the smart home, the offender could spy on the inhabitants sexual or daily activities for his or her sexual relief.

In addition, one of the most plausible scenario described by the analysts was that in which an offender stole sex-related amateur videos recorded in people’s homes or hotels. The videos could either have been recorded intentionally by the inhabitants themselves, or by the hacker controlling their home cameras and microphones. These videos could be used for blackmail purposes or even for political gains in cases where high-caliber political actors are recorded.

It should be noted that similar cases have happened before, for example in the case of Miss Teen USA whose webcam had been hacked into, and used to take her nude photos in her bedroom. The offender was only discovered when he tried to blackmail the victim and force her to send him more nude photos [25]. He had been arrested, along with 97 other offenders who hacked into victims’ webcams to spy on them remotely, using software commercially sold for less than $170 [26]. While in these cases the offenders hacked into their victims’ computer webcam, similar crimes can be expected to occur using IoT devices as well.


The IoT holds great potential to make a positive impact on the world, but it also makes us highly valuable to cyber-attacks. As Marc Goodman wrote, “when everything is connected, everyone is vulnerable” [27]. The digital world is filled to the brim with digital criminals, hackers, virus programmers, ransomware spreaders, hacktivists and all possible kinds of people who skirt on the edge of the law at best, or violate it completely at worst. As we connect our things to the internet, we will give all of the above access to our critical infrastructure, our houses and even our bodies.

In this research we created a list of scenarios, ranked by plausibility, that describe novel ideas for acts of crime and terror that rely on the IoT. We described in length the four most plausible scenarios and have shown that they are indeed highly likely – and some have already began happening in some preliminary versions.

While we do not believe that these 21 scenarios can even come close to describing the full use that criminals and terrorists will make of the IoT, we see this paper as a starting point for more in-depth research on the issue. Hopefully, such research will shed more light on this urgent issue, and will serve to warn governments, private companies and individuals of the dangers ahead of time.
