Impact of Proactive Cyber Threat Intelligence on Exploits from the Dark Web

Impact of Proactive Cyber Threat Intelligence on Exploits from the Dark Web

Lawrence J. Awuah

 

Abstract: The desire to defend against the ever-growing cyber threat landscape necessitates the need to link exploits from the Dark Web to known vulnerabilities with the sole aim of proactively utilizing Cyber Threat Intelligence (CTI) solutions, with Deep Learning (DL) model and Exploit Vulnerability Attention Deep Structured Semantic Model (EVA-DSSM), to maximize data protection, privacy, and security.

 

A review of “Linking Exploits from the Dark Web to Known Vulnerabilities for Proactive Cyber Threat Intelligence: An Attention-based Deep Structured Semantic Model”. By Samtani, S., Chai, Y., & Chen, H. (2022). MIS Quarterly, 46(2), 911-946. DOI: 10.25300/MISQ/2022/15392

Summary: “Black hat hackers use malicious exploits to circumvent security controls and take advantage of system vulnerabilities worldwide, costing the global economy over $450 billion annually. While many organizations are increasingly turning to cyber threat intelligence (CTI) to help prioritize their vulnerabilities, extant CTI processes are often criticized as being reactive to known exploits. One promising data source that can help develop proactive CTI is the vast and ever-evolving Dark Web. In this study, we adopted the computational design science paradigm to design a novel Deep Learning (DL)-based Exploit Vulnerability Attention Deep Structured Semantic Model (EVA-DSSM) that includes bidirectional processing and attention mechanisms to automatically link exploits from the Dark Web to vulnerabilities. We also devised a novel Device Vulnerability Severity Metric (DVSM) that incorporates exploit postdate and vulnerability severity to help cybersecurity professionals with their device prioritization and risk management efforts. We rigorously evaluated the EVA-DSSM against state-of-the-art non-DL and DL-based methods for short text matching on 52,590 exploit-vulnerability linkages across four testbeds: web application, remote, local, and Denial of Service. Results of these evaluations indicate that the proposed EVA-DSSM achieves Precision at 1 scores 20% – 41% higher than non-DL approaches and 4% – 10% higher than DL-based approaches. We demonstrated the EVA-DSSM’s and DVSM’s practical utility with two CTI case studies: openly accessible systems in the top eight US hospitals and over 20,000 Supervisory Control and Data Acquisition (SCADA) systems worldwide. A complementary user evaluation of the case study results indicated that 45 cybersecurity professionals found the EVA-DSSM and DVSM results more useful for exploit-vulnerability linking and risk prioritization activities than those produced by prevailing approaches. Given the rising cost of cyber-attacks, the EVA-DSSM and DVSM have important implications for analysts in security operations centers, incident response teams, and cybersecurity vendors.” 

Keywords: cyber threat intelligence, deep learning, deep structured semantic models, vulnerability assessment, hacker forums, dark web, security operations, cybersecurity analytics 

The desire for researchers and subject matter experts to help organizations understand the complexity of attack vectors and support their cyber defense with automated incident response capabilities, driven by machine intelligence, has become so critical in today’s world. We have reached a point where cybersecurity trainees, researchers, and professionals need to continuously gain insights into innovative cybersecurity solutions in the field. The fact that malicious actors consistently use hacking techniques to circumvent security controls and exploit system vulnerabilities in the wake of the current threat landscape motivated Samtani et al. [1] to develop proactive Cyber Threat Intelligence (CTI) model from the perspective of the Dark Web. More to the point, pattern recognition, anomaly detection, and predictive analytics remain to offer threat intelligence and cybersecurity analytics capabilities that are key ingredients in automated incident response and threats mitigation efforts in the ever-evolving threat landscape.

Additionally, machine intelligence has become so ubiquitous and an indispensable tool, in defensive and offensive operations, that it remains to be a useful resource to cybersecurity leaders and device vendors. As part of their study, the authors adopted a novel Deep Learning (DL)-based model, an Exploit Vulnerability Attention Deep Structured Semantic Model (EVA-DSSM), which comprises bidirectional processing and attention mechanisms with the capability to automatically link exploits from the Dark Web to known vulnerabilities [1]. Additionally, a Device Vulnerability Severity Metric (DVSM) model was developed to be employed by cybersecurity professionals when engaging in device prioritization and risk management activities. A high-Level CTI Framework that captures EVA-DSSM and DVSM models is depicted in figure 1.

In another study, Zhu et al. [4] adopted a computational design science solution to develop a DL-based, hierarchical, multi-phase Activity of Daily Living (ADL) framework to address similar concerns. Yet, others deployed Tor-use Motivation Model (TMM) and found a network impacted by illicit commerce and money laundering and concluded that criminality on this dark web is based more upon greed and desire, rather than any particular political motivations [3]. These models and frameworks play key roles in emerging cybersecurity mitigation strategies.

Moreover, the vulnerability assessment as part of the automated CTI process, coupled with analytics, facilitate intelligence required by CTI professionals to conduct initial triage of security incidents for anticipated mitigation strategies. Motivated by the dynamic threat landscape, the authors develop a CTI framework and compared the operational differences between the conventional DSSM and their proposed EVA-DSSM [1]. When the proposed EVA-DSSM model was evaluated against both non-DL and DL-based methods for exploit-vulnerability linkages across selected testbeds (figure 1), the DL-based technique was determined to have achieved a much higher precision than the non-DL counterpart.

Furthermore, when a user evaluation of the CTI case study was conducted, the results indicated that a number of cybersecurity professionals found the EVA-DSSM and DVSM to be more efficient in exploitation-vulnerability linking and risk prioritization activities than those produced by conventional solutions. On the other hand, the user evaluation indicated that these professionals serving in the Security Operations Center (SOC), Incident Response (IR), Vulnerability Management (VM), and Operational Cybersecurity (OS) domains of practice found the EVA-DSSM and DVSM results more useful than those generated without these two models (figure 1). Given the rising cost of cyber-attacks, the EVA-DSSM and DVSM have perceived practical significance and important implications for analysts, for example, in the areas of security operations centers, incident response teams, and cybersecurity vendors.

In summary, there is a strong desire to support the fact that the practical and theoretical significance of the proposed EVA-DSSM and DVSM models evidently benefits analysts in SOC and IR teams, as well as security operations vendors. From the preceding analysis, there is also evidence to suggest that DL-based machine intelligence, as noted by the authors, plays a key role in SOC-related engagements. To that end, in mitigating evolving threats, organizations should empower the security operations teams and vendors with automated AI-based mitigation solutions. To efficiently mitigate these threats, organizations should endeavor to empower the security operations team and leadership with appropriate strategies needed to offer security orchestration and response processes to fully automate and manage the complexity of the SOC ecosystems [1-2]. In other words, the ability to seamlessly automate and manage the complexity of security operations to address the dynamic threat landscape remains an important challenge for security researchers, cybersecurity professionals, and cybersecurity vendors. Finally, from the preceding analysis, the EVA-DSSM and DVSM models certainly have crucial implications for those analysts in the SOC-based environment and cybersecurity vendors. Researchers and professionals alike have a major role to play in search of broader cybersecurity solutions for the interest of society.

Non-consensual Pornography: How petty desire becomes a tragedy to an individual.

Viewpoint by Heeju ROH (Harvard Business School)

There was a woman.
She did an ordinary love.

It was not a love life that bares all things, believes all things, hopes all things, and endures all things. But there was an affection: she and her lover couldn’t say each other’s name without smiling. There was a trust. The two people did not feel guilty about their own unspoken things. There were a lot other things and the love brought all of them. They thought, as it is commonly said, that they fell in love. However, it was wrong. By nature, love is not something you can consciously fall into. Love strikes people as if it is an accident. So it was rather obvious that it was also the love who called the end.

As left-overs, they did not know how to deal with the situation because they were both victims. Since the love already left them, their frustration lost its direction to head and destined to wrong targets – each other. Through the time of hurting each other more and more, they somehow survived as two separate individuals. And that was supposed to be it. But one day, she was told that there are pictures and videos of her privacy online. Records of their love, including evidences of the intimacy. Indeed, she could see two bodies. One of those had the same face with hers. However there was a difference between the face in the monitor with the face that she reflects on a mirror every morning. The face in the monitor did not have dignity or self-respect. It did not have a name or identity. It was merely a visual material to facilitate the ejaculation. Yet, it was undoubtedly her face and body.

I admit. Above case cannot possibly be the only background story of nonconsensual pornographies (NCP) in this big world. Maybe there are other victims who has been through a bad breakup, an abusive relationship, or other terrible situation before the leakage. Even if an uploader has built an aggression toward a victim, he or she does not earn an authority to share the private moment with unspecified mass viewers. We all should agree that the distribution of such material cannot be justified under any circumstance, period. However, we are often misled by the name ‘Revenge Porn.’ We are misled in a way that the victims are deserved to be revenged. More importantly, this perception results a general tendency to highlight an interpersonal and emotional conflict between the perpetrator and the victim, while diluting the fact that the NCP is a collective cybercrime. No wonder why bystanders who are unlikely to commit such crime shows certain level of approval upon NCP[i].

So, do I want to claim that NCPs are not really the result of ‘revenge’? Maybe, but that’s not the point. Currently, frequently suggested strategies to stop the NCP is more focused to victims’ protecting themselves. The reasons said are 1) that the victim must’ve agreed on the intercourse itself and 2) that, due to the highly viral environment of online platforms, the identification of the victim and instant reaction is better taken by the first party, the victim, than by the third party, the law enforcement for example. This could be also why even well-respected Medias rather recommend victims to “make sure that your face is not on the picture” or “use more secured application.”[ii] This tendency is an unfiltered evidence of our ignorance. The ignorance about the magnitude of the damage to the victims and the ignorance about the nature of the situation – the crime. The society forces the victims should be the one taking the burden of erasing fees and legal procedures, while dealing with PTSD, trust issues, and hostile social perception of “you deserve it”[iii]. Compare to the severe physical and psychological pain of the victims, the purpose of the NCP is ridiculously shallow – the amusement.

In the online world, we easily let ourselves indulge. Online world is the perfect place to let all of us to swim in the sea of our own gluttony, envy, greed and lust. Of course, it is rather acceptable if the voyeurism is directed to something not ethically challenging, such as mother’s recipe for the banana cake. Sharing information is the accomplishment of the 3rd industrial revolution. However, behind the curtain of anonymity, we also can consume other people’s private life easily and casually. And as the word ‘we’ suggests, there hardly is a sole perpetrator in the online world. They commit to this cyberbullying by creating, consuming, distributing, and making profit from NCPs. When facing the collective wave of violent behavior, individual victims always fail to protect themselves. Examples of victories are absolute minority considering the entire number of victims. The victory has to become our social norm, the general outcome, and expected result.

I believe that laws, policies, and systems are to stand at the front line of this battle. People’s feeling safe from possible harassments is the first job for normal nations to achieve. If people can hurt others and be hurt by the technology facilitated sexual violence without any rational expectation to be salvaged, that status is rather similar to the fight of all against all. To end this fight, we need more victim-focused responses. From the investigation processes, which are often traumatic for victims, to subsidy for erasing the materials and punishing the distributors[iv]. There have been studies and implementation of policies conducted. However, in reality, victims are rather to rely on civil associations than on law enforcement, because the civil associations tend to have more experience in such cases[v]. While the NCPs have become more accessible and affordable, the prosecutorial process has not become victim-friendly. Victims have to endure the ongoing tragedy until the legal process is over, which does not guarantee a fresh clean-up. As a result, the victims are easily left in the blind spot of the system.

Screaming requires a lot more effort than you think. It is not a knee-jerk reflection. Firstly the lungs have to be inflated as big as possible. Then your abdomen has to be flat and tighten in order to expectorate the air. At the moment of exhalation, the vocal cord tremors to deliver the sound wave. It’s a duty of nasal cavity to increase the sound frequency. Finally, as a quasi-verbal communication, this single-syllable sound has to deliver a message: Somebody help me. Unfortunately, the brain cannot often orchestrate the process. It endeavors to send signals to your lungs, abs, and vocal cords, but they simply fails in doing their works.

She felt that she had to scream at the moment she found her pictures. If the screaming was a cardio exercise, her brain must have sweated to be dehydrated. But the brain cannot sweat. So something else did instead: Her eyes released vast amount of salty water. Taking that as a signal, the other body parts finally responded. But it was different from what she imagined. The sound was rather low and growling. It was similar to something that every creatures make in the time of tragedy. It was an ordinary end of an ordinary love. However, because tragedies does not have an eye, they sometimes just barge into an ordinary life. So her ordinary life suddenly became tragic.

On the website, she also found other women. The women who also had faces and bodies without the name and dignity. She wondered what made all these women exposed. What have they done? And she realized that she already knew the answer – an ordinary love. They all did an ordinary love – no more, no less. Just an ordinary love.

Viewpoint – Trolling: annoyance or real threat?

Trolling: annoyance or real threat?

Viewpoint by Daniel Grieb, Flora Guise, Léontine Paquatte (ESSEC Business School)

 

Macy’s 2008 Thanksgiving Parade, New York City: American music artist Rick Astley surprises spectators with a live performance of his 1987 song “Never gonna give you up”. Leading up to his performance, the year 2008 saw the rise of a mass internet phenomenon called “Rickrolling”, where millions of users were enticed to click on hyperlinks leading to the music video of the Astley’s song. From this innocent internet prank, trolling has evolved to much more: during the US presidential election of 2017, the concern of the impact of trolling on the public’s opinion has become evident. This paper aims to explore the internet phenomenon “Troll” and will cover their motivations to their impact and current, relevant examples of trolling.

As the phenomenon of “trolling” is a rather recent emergence, there is still no clear, universally agreed upon definition in the academic field. However, a common definition reflects the most observed “trolling behavior”: it describes the act of agonizing others online “by deliberately posting inflammatory, irrelevant, or offensive comments or other disruptive content” “with no apparent (…) purpose”. [1] [2] The troll’s motivation can be categorized in three categories: (1) Personal enjoyment (pleasure seeking through “trolling”), (2) Revenge (as a reaction to being trolled) and (3) Thrill-seeking (deriving joy from the reaction of others to their trolling behavior). [3] It becomes evident that the current definition and motivation associated with trolling focuses on the individual level: it assumes that trolling is exclusively done by individuals and with no external goal. However, numerous, recent examples, show that trolling has evolved.

Trolling basically manifests itself in a malevolent, interpersonal and antisocial individual behavior. Concretely its about “deliberately [provoking], upsetting others by starting arguments or posting inflammatory messages on online comment sections.”[4] The manifestation of individual trolling through online comment sections can be observed through the increasing phenomenon of cyberbullying, identity theft and cyberstalking, therefore putting flesh on the Dark Tetrad personality traits: narcissism, sadism, Machiavellianism and psychopathy.

Quantitative analysis have shown that the online context tends to exacerbate psychopathic behaviors: anonymity, normlessness, asynchronicity on the internet are putting more psychological distance between the troll and his/her target, therefore encouraging him/her to have a sharper and more violent reaction than in an offline context.[5]

The impact of this individual cybertrolling can be seen on many aspects of the life of some victims ever since the phenomenon appeared: the Youth Risk Behavior Surveillance System (YRBSS) identified behavior such as drug use, unhealthy diets and numerous other examples linked with cyberbullying.[6] Even though social networks and interpersonal websites have implemented rules and means of empeaching of trolls, the line between elements considered bullying and justified opinions is not clear, allowing internet trolls to adapt their behavior without being reprimanded.

Looking at the nefarious effect internet trolls can cause on an individual level, the threat of trolls on a societal level seems to arise.

The digital transition has brought the Greek ideal of the public agora to a brand new level: the internet turned into a global, geography-free space where almost anyone can express one’s opinion.[7] Roger Silverstone designated it in 2006 as the “Mediapolis”[8], where people can gather and participate to the virtual debate without being present, reminding the theory of “Global Village” of Marshall McLuhan.[9] It looks like the internet allowed us to become an egalitarian network society with a perfect level of freedom of speech. As it turns out however, that space of freedom became the playground of trolls and haters, breaking down this utopia and questioning models such as deliberative democracy: Trolls, fake news and hate speech occupy so much space on forums, that this may lead to eventually silencing some citizens as they do not want to become the target of trolls or to making citizens lose touch with what is true or not.[10] Disinformation, hate-speech and cyber-harassment have become real threats for democracies as they impede a reasonable, objective public debate which is the basis of this political system. It is therefore necessary to take measures to resolve this problem, however without falling into censorship: a very sensitive, but essential endeavor.

To illustrate this problem, let us take a look at the propaganda movement led by “Reconquista Germanica” that became active during the last Germany’s general election.[11] This group of online extremist used trolling to manipulate the election by spreading hate, fake news and Kremlin propaganda. The techniques used for their “Blitzkrieg against the Old Parties” proved to be very efficient. First, they trolled their opponents by spreading illegally obtained, compromising private content or even manipulated photos and collage, in the hopes that these would become “viral hits”. They also tried to manipulate public opinion by conducting a “war on information” with disinformation, hateful memes and bots sending automated messages. This way, Reconquista was able to get great visibility and influence the opinion particularly among a large proportion of undecided voters. Moreover, these techniques are becoming more and more professionalized and globalized since some groups of activists claim that they influenced Russian, American, British, German and French elections. They now apply very detailed action plans and have become organized world-wide. Yet, while it is still difficult to measure their real influence, trolls have become a cyber-threat that should in no way be neglected.

It became evident that internet trolling can become more than just a simple annoyance: the organized and strategic implementation of “trolling tools” on social media such as hate speech and doxing, can not only have a significant effect on the trolled “victims” but also on societies. Influencing public opinions has become the new goal of organized trolling networks and their first implementation prior to elections can be seen. While the lone internet troll may seem harmless, the influence and impact of an organized community of trolls should not be underestimated. Just like in many aspects in life, Paracelsus’ rule remains true – even on the internet: Sola dosis facit venenum “The dose makes the poison”. And the instrumentalization of this dose by different interest groups has become a new form of cyberthreat.

Blockchain Regulatory Framework, Legal Challenges and the Financial Industry

Blockchain Regulatory Framework, Legal Challenges and the Financial Industry

Camille Madec

Introduction

In order to stay competitive, financial industry must seize the opportunities of the on-going technological disruption, and particularly with the recent so-called blockchain innovation when some argue that this new technology has the potential to replace banks as financial intermediaries for transfer and exchanges of money. In this transitional context, financial sector could face new cybersecurity risks, with sophisticated attacks, which eventually call for a renewed regulation framework. Here the financial sector means banks, insurers, asset managers, and advisory firms.

Blockchain can be defined as “a peer-to-peer operated public digital ledger that records all transactions executed for a particular asset (…) The Blockchain maintains this record across a network of computers, and anyone on the network can access the ledger. Blockchain is ‘decentralised’ meaning people on the network maintain the ledger, requiring no central or third party intermediary involvement. […] Users known as ‘miners’ use specialized software to look for these time stamped ‘blocks’, verify their accuracy using a special algorithm, and add the block to the chain. The chain maintains chronological order for all blocks added because of these time-stamps.” (Alderman, 2015)

Hence, Blockchain, well known through the so-called bit coin, could open much more perspective and should guaranty security and the validation of all the exchange of data. In addition to open room for new business opportunities, this new technology could disrupt the legal conception of privacy, intellectual property right, and presents some issues regarding financial institution accountability given the new associated risks. As a consequence while financial institutions have been under strengths by the new regulatory requirements in the aftermath of the 2008 financial crisis, they might see their accountability rises again to address cybersecurity risks and associated prejudices related to blockchain innovation.

This paper explains how business compliance to new cyber regulatory framework is a strategic issue for financial institutions. It presents the financial institutions specific data profile and linked eventual collateral damages. It highlights blockchain innovation opportunities and associated new cybercrime challenges. It describes the current European regulatory framework and legal accountability scenarios. It then finally supports the hypothesis of cyber compliance as a corporate competitive advantage and maps out some elements
of potential recommendations to strengthen cybersecurity resilience.

How is Cybercrime Evolving? (editorial)

How is Cybercrime Evolving? (editorial)

Jean-Loup Richet, Sorbonne Business School (IAE de Paris)

Abstract

Firms spend enormous resources on digital advertising and promoting their brand online. In the meantime, ad-fraud undertaken by cybercriminals cost $42 billion in 2019 and could reach $100 billion by 2023. However, while digital advertisers continue to wrestle with how to effectively counteract ad-fraud, the topic of advertising fraud itself has received little academic attention. Here, we investigate this gap between practice and research through an exploration of ad-fraud communities. Our research implemented a multimethod approach for data collection in a longitudinal (18 months, October 2017 to April 2019) online investigation of this phenomenon. Integrating qualitative and quantitative analysis, we examined (1) internal interactions within ad-fraud communities and (2) ad-fraud communities’ performance and growth. Our online investigation extends our conceptual understanding of ad-fraud and explains how ad-fraud communities innovate. Our findings indicate that capabilities enacted by some communities foster requisite variety and enable the coordination of complex, iterative, and incremental dynamics (cocreation of artificial intelligence-based bots, customer involvement, and reinforcing capabilities). This research has both theoretical and practical implications for innovation in cybercriminal communities. Furthermore, we provide practical guidance for policy-makers and advertisers regarding how to improve their response to business threats. Indeed, a better understanding of how ad-fraud communities innovate enables organizations to develop countermeasures and intelligence capabilities.

Highlights

• This is one of the first studies documenting the way ad-fraud communities innovate and create value for their criminal customers.
• A multimethod approach was applied for data collection, integrating qualitative and quantitative assessment of six cybercriminal communities.
• Specialized ad-fraud communities provided a wealth of knowledge and incremental innovations in ad-frauds.
• General and customer-oriented ad-fraud communities showcased the most internal interactions, as well as exhibiting better performance and growth.
• General and customer-oriented ad-fraud communities have developed specific capabilities, focusing on innovation through artificial intelligence, which fuels customer engagement and fosters (criminal) attractiveness.

Cybersecurity and the Internet of Things

Cybersecurity and the Internet of Things

Sarah Baker, Grégoire Frison-Roche, Barbora Kuncikova

Abstract:

The Internet of Things (IoT) is a topic that gets a lot of attention and has become somewhat of buzzword in business and technology today. In many ways, this hype and excitement is not misplaced, as IoT has fascinating implications and opportunities for both consumers and businesses. However, the cybersecurity threats that this explosive growth represents are sometimes overlooked or not clearly understood. This paper will introduce the concept of IoT, including the definition, trends and applications. The next section will discuss the potential cybersecurity risks for IoT, for both industries and consumers. Finally, the last section will discuss recommended preventative measures and defense mechanisms available, while considering the fast changing nature of IoT technology.

Introduction: What is the Internet of Things?

The past decades have seen huge advances in electronic communications, from the rise of the Internet to the ubiquity of mobile devices. However, this communication is now shifting from devices that simply connect users to the Internet, to communication linking the physical world to the cyber world (Borgia, 2014). Generally speaking, this notion is called Cyber Physical Systems (CPS) and includes technologies such as (i) automation of knowledge work, (ii) Internet of Things, (iii) advanced robotics, and (iv) autonomous/ near autonomous vehicles (Borgia, 2014). However, IoT is considered to be the CPS technology with the largest expected economic impact (Manyika et al., 2013).

Given IoT is one of the most talked about trends in IT, there are as many definitions of the phenomena as there are angles to study. The origins of the concept IoT can be traced back to a group at MIT, who defined it as “an intelligent infrastructure linking objects, information and people through the computer networks, and where the RFID technology found the basis for its realization’’ (Brock, 2001). Today, IoT extends far beyond RFID technology. A more recent definition describes IoT as “a highly interconnected network of heterogeneous entities such as tags, sensors, embedded devices, handheld devices and backend servers” (Malina et al., 2016). The International Telecommunication Union (ITU) describes IoT as “anytime, any place connectivity for anyone… connectivity for anything. Connections will multiply and create an entirely new dynamic network of networks – an Internet of Things’’ (ITU, 2005).

Therefore, the defining attribute of IoT is that it involves things, moving beyond networked computers, tablets or smartphones to include just about any physical object that can be connected and communicate. The value offered by IoT comes from the fact that these objects which are not machines, and do not function like machines are able to gather and communicate data, which means information can be translated into action at astounding rates (Burrus, 2014). The concept behind IoT was aptly captured back in 1999:

If we had computers that knew everything there was to know about things — using data they gathered without any help from us — we would be able to track and count everything, and greatly reduce waste, loss and cost. We would know when things needed replacing, repairing or recalling, and whether they were fresh or past their best. The Internet of Things has the potential to change the world, just as the Internet did. Maybe even more so” (Ashton, 2009)

Cybersecurity & Cyber Threats in Healthcare Organizations

Cybersecurity & Cyber Threats in Healthcare Organizations

Aurore Le Bris, Walid El Asri

Abstract:

Cybersecurity has become a strategic issue for healthcare facilities. This current risky situation comes from an internal double threat: the misuse of IT systems by employees due to their low risk awareness and the lack of proper funding dedicating to Information Security. Simultaneously, the democratization of hacking techniques has also increased the number of potential perpetrators and the variety of their profile. The multiplication of healthcare facilities hit by such attacks reveals how absolutely necessary the question of cybersecurity is. Thanks to the mediatization of these incidents, concerns now grow among general public and authorities, which trigger more and more initiatives to turn things around: FDA, AHA, HITRUST in the USA. A move towards more coordination in necessary. Furthermore, facilities’ staff is essential in solving the hacking issues. Indeed, cybersecurity cannot be improved without training employees to use devices properly, raising their awareness on cyber threats and ensuring their compliance with security policies.

Introduction

Cybersecurity has become a crucial issue for many organizations but also for private individuals. As well as for “regular” crime, anyone may become a target of ill-intentioned people, exploiting the vulnerabilities of information systems (IS) in any possible way. Healthcare organizations are some of the entities we trust the most and that hold the most sensitive information about us: name, date and place of birth, medical records, social security details, etc. Suffering from many flaws (low budget, lack of IT organization, excessive use of legacy systems…), healthcare actors have become easy targets for hackers, facing more and more pressure and threats from them (Fu and Blum, 2013).

This article aims at depicting the current state of cybersecurity in healthcare organizations as well as at understanding the main cyber threats they face and how these last ones could be addressed.

First of all, the stakes and risks associated to the healthcare environment will be presented. The different types of assets likely to be targeted will be reviewed as well as the profile of the potential attackers/threats and their objectives. Then, examples of attack scenarios – that occurred in real life or pentests – will be studied in order to highlight the consequences they may have on healthcare IS. Finally, the current state of cybersecurity in healthcare facilities will be portrayed and possible measures to enhance it will be discussed.

The following strategic report assess new risks and threats towards healthcare facilities and organizations. Read the full report here:

A Strategic Approach to the Tor Network

A Strategic Approach to the Tor Network

Why should firms go dark?

François Courset,­ Margot Favennec, Candice Hamou

Abstract:

The dark web should be considered by companies for various reasons. It offers a large panel of useful tools that can be crucial for negotiation or security. Moreover, even if it can appear as a niche network, opening an onion version of the companies’ websites might help them to boost their image. It can also bring new users to the website, users that usually cannot reach it because of censorship issues. Finally, we have seen new emerging trends related to the dark web. The Tor network might be seen in the future as a guarantee of security online but it can also deeply change the way data are used. Taking into consideration the dark web, not only as a place of illegal activities, but also as a new channel with its own opportunities and constraints is thus essential for all decision-­makers.

Introduction: For the Web is dark, and full of terrors?

The Dark Web has been fascinating and fueling the imagination of many Internet users for a few years now. The collective art group Mediengruppe Bitnik even created a Random Darknet Shoper, a bot which bought a random object from the darknet market place Agora and then sent it to the two artists in charge of the project. This artistic project, aiming at debunking consumerism, showed yet that drugs are not the only things you can find on the Dark Net. You can also find everything you buy in the “clean world”, and buy these with a refund service -­ the two artists received a refund for a bag that was no longer available.

The Dark Web, instead of being the place gathering the worst side of humanity (drugs, pedophilian contents…) could also thus be a place where a real economy grows and prospers.

That’s why the following question deserves to be asked: can the Dark Web be profitable for firms then? Could a reliable “dark” business model exists and could the dark web be used as a almost regular tool to increase a firm’s profit?

First things first, the Dark Web is often misperceived among the global population since the media hype mainly focuses on scandals such as Silk Road’s. This tends to depict it as a place where you can find barely anything illegal, from drugs to hitmen. Yet the Dark Web is not only about illegal traffic. It is much more than that. What’s more, a distinction has to be made, a distinction that is far to often forgotten or neglected. As shown by the two pictures you will find in the report (page 3), there are different levels beneath the “Surface Web” we all know. First comes the “Deep Web”, where you can find many reports, storage datas, and again underneath this Deep Web comes the “Dark Web”, where all communications are encrypted. Now let’s clarify what each term means:

Deep Web: information not accessible with a regular search engine. It is a Web concept regarding search engine (Bergman, 2001).

DarkNet = Dark Web = Tor = information not accessible with a regular search engine or a browser.

The Deep Web has a far larger content that the Surface Web: 1GO of indexed page versus 550GO of deep web page and 19TB of indexed content versus 7500 TB of deep web content, to quote only but a few numbers from a recent study. To be really thorough, Dark Nets are all the overlay networks on the Deepweb, and Dark Web is the content of some Darknets. Thus one DarkWeb may be considered as a small portion of Deep Web. Deep Web and DarkWeb are very often confond, yet they are not the same!

We chose to focus on Tor since this is what most people use to get into Darknets and to browse the Web anonimously. Tor enables you to protect your privacy while looking at any webcontent, and from our point of view, this is one crucial asset for a business model based on the use of Darknets. In the wake of the growing yearn for privacy and of protest against wild data collection, Tor is definitely something firms should get interested in.
