5 Lessons Organizations Can Learn from the Worst Data Breaches of 2020

While data breaches are invariably costly for organizations, the fallout from a data breach isn’t always the same. There are numerous motivations for threat actors and an even greater number of strategies that they employ to achieve their varied goals. As such, it falls to security professionals can continuously learn from the ongoing cyberattacks the best ways to predict and prevent cyber breaches in a constantly evolving threat landscape.

In this article, we take a look at 5 of the lessons that can be learnt from some of the biggest cyberattacks of 2020.

1. 3rd party integrations create new attack surfaces

The recent breach of SolarWinds allowed foreign agents to access and spread malware to numerous government agencies and high-value US targets. These threat actors knew they could likely never penetrate these targets directly, and instead discovered they all used the same software for network management - SolarWinds. 

The attack spread a malware which lay unnoticed in the system for months as the attackers are believed to have observed and gathered data on their targets.

The key take away from this hack is that no matter how excellent and strict your own system’s security is, if the 3rd party systems you use have a weakness, then so do you. This is especially important as systems become increasingly interconnected, with a myriad of moving parts provided by dozens of different vendors. 

While you can’t and shouldn’t simply wall of your systems with a trust no-one approach, organizations also mustn’t take third-party solution provider’s security for granted. Conduct rigorous, ongoing security audits of your systems to be sure there’s not a nasty surprise hiding around the corner.

2. You need clarity across your organization’s security

As an organization grows in size and complexity, often, as we mentioned above, integrating and employing 3rd party vendors, the number of attack surfaces grows too. Organizations need systems in place to maintain clarity over the entirety of their IT security.

In July, Garmin was locked out of its own systems by ransomware and ended up having to pay millions in ransom for the decryption key. 

Garmin faced an impossible situation. While law enforcement officials and cybersecurity experts repeatedly warn companies not to pay ransomware attackers as it encourages further ransomware attacks, companies like Garmin are often left with no other choice. 

As such, companies need to employ systems, security protocols, and training to prevent ransomware.

For businesses like this, it’s vital to have systems in place to maintain a vigilant security posture toward every possible vector for attack.

3. Humans are the weakest link

Social engineering tactics can range from rather obvious emails from Nigerian princes to complex multi-step and highly targeted spear-phishing campaigns. In late 2020 the latter is what happened to Twitter, with numerous employees targeted with a strikingly elaborate spear-phishing campaign. The strategy involved multiple steps including tricking an employees phone carrier, pretending to be a member of the I.T. team, and creating fake login pages.

Once they had an employees admin account login they hijacked multiple high profile Twitter accounts and launched a Bitcoin scam that saw them making off with over $100,000 in less than an hour before it was stopped. Though this attack certainly could have been worse, it shows how one of a companies biggest vulnerabilities is compromised employee credentials. 

There are a couple of things that can be done to protect against employee weakness in your security defences. These include restricting employee access to sensitive data. Ensuring you offboard, and remove access to systems for old employees, implementing strong authentication protocols such as multi-factor authentication, and regular security training sessions for staff 

4. Only store data vital to providing your service

In July of 2020 GEDMatch, a DNA genealogy site was hacked. The hackers changed the user’s privacy settings - opting everyone in to share their data with law enforcement. The hack exposed the data of around 1.4 million people.

Thankfully, GEDMatch later announced that no raw DNA files had been compromised as no raw data is stored on the site. Instead, the data is encoded when it’s uploaded and the raw file deleted immediately. The key lesson here is that GEDMatch followed good practice, not storing any sensitive raw data and thus eliminating a potentially serious attack vector meaning the failure of one control did not lead to the attackers progressing beyond their initial intrusion.

If you can avoid storing highly sensitive data — such as passwords, payment information, or biometric data — on your own servers, do so. Deleting raw DNA data helped minimize the damage to GEDMatch in this breach.

5. People aren’t going to stop reusing passwords

The majority of people on the internet don’t know the best online security practices and many reuse the same tired old password across numerous websites. This has lead to a rise in popularity of one of the most common attack strategies employed by threat actors, credential stuffing. This is when they buy large datasets of login details, eg. passwords and user names, and apply them to other sites. While the strike rate is generally quite low, this strategy of credential stuffing does work. This is what happened to several insurance companies in 2020 including Independence Blue Cross. 

Independence Blue Cross reported that their member portals had been improperly accessed by hackers reusing credentials stolen from MyFitnessPal in an attack from 2018.

People aren’t going to stop reusing passwords anytime soon, but businesses can still guard against credential stuffing. One crucial step is to implement strong authentication protocols such as multi-factor authentication or adaptive authentication, which asks users for more credentials if their behavior is suspicious. In this case, it could have noticed that members were logging in with new I.P. addresses or at an unusual time of day, and asked them to confirm their identity.

Final Words

Organizations are increasingly connected online, using a myriad of integrations and tools to create better, more user-friendly solutions. Additionally, as we all become more technologically literate and engage more and more online there is an increasing amount of users data stored on organizational systems.

This means that the number of attack surfaces that organizations have to be aware of is continuously growing, and so too are the opportunities for attackers to achieve their goals. Whether it’s foreign espionage, idealogical fanatacism, or for personal financial gain.

Ultimately, we’re all in this together, a data breach or successful attack on one company could easily have ramifications against your own organizations. As such, employing the right tools, such as an OSINT tool like Signal, to monitor, detect and better protect against potential threats in this growing threat landscape has never been more important. 

The Threat of Doxing to Organizational Security

What is Doxing?

The term itself originates from the phrase “dropping docs” and was later shortened to “docs” and then “dox”. As the original term suggests, doxing is when someone collects and then shares information about another person or organization.

There are numerous reasons someone might dox someone else or be the victim of doxing. It could be for revenge or a personal grudge, a disgruntled ex-employee might target their previous employer, for example. In 2014, Sony was the victim of a doxing attack backed by, experts believe, the North Korean government after they released a film which made fun of their leader. Other motivations include harassment and cyber-bullying, vigilante justice (for example, exposing neo-Nazi’s), and doxing for financial gain. 

Organizational doxing is on the rise and can be immensely damaging, exposing company secrets and customer data, or more directly exposing executives to new levels of threats.

Doxing Strategies and Goals

Traditionally doxing started with an online argument escalating to one person digging out information on their adversary and sharing it online. More recently though, doxing has become more of a cultural tool with hackers taking down people or groups with opposing ideologies. When it comes to organizations, threat actors have been known to both target an organizations reputation and to use information gained through a doxing attack to leverage financial reward.

For example, in one scenario an employee at a bank was blackmailed after a doxing attack into using his position in the bank to steal over $100,000 from customers for his blackmailers. 

The fallout is generally reputational with the victim suffering from online abuse such as death threats to them and their family in lieu of the new information shared. However, on occasion, the fallout can be significantly worse. There have been examples of mobs dishing out physical vigilante justice after a person's information, such as an address, was shared online.

There are numerous ways you can be identified online. By following ‘breadcrumbs’ of information a dedicated doxxer can assemble an accurate picture of a person - even if they were using an alias. The kind of details they might look for include, full name, current address, email address, phone number etc. Additionally, some doxxers might buy information from data brokers.

IP/ ISP Dox

There are various methods that can be used to locate your IP address, which is linked to your location. With just your IP address a doxxer could then use social engineering tactics against your Internet Service Provider (ISP) to discover the information they have on file such as:

• Your full name

• Email address

• Phone number

• ISP account number

• Date of birth

• Exact physical address

• Social security number

This requires the doxxer to go through a dedicated process, which may not even work, however, it’s just one strategy they can employ, and even if they are unable to gather further information through a gullible ISP worker they still have the first parts of the puzzle - your IP address and a rough location.

Doxing with Social Media

If your social media accounts are public then anyone can view them. Often things a threat actor can find out include your location, place of work, your friends, your photos, some of your likes and dislikes, places you’ve been, names of family members, names of pets, names of schools you attended, and more.

With this kind of information, they can then find out even more about you, or even discover the answer to your security questions helping them break into other accounts such as your online banking.

As such it’s recommended to keep your social media profiles private, and if you use multiple online forums to use a different name and password for each to help prevent doxxers from compiling information from across multiple online forums and social media sites. 

Data Gathered through Brokers

Data brokers on the internet collect information from publicly available sources and then sell the data for profit. Generally speaking, they sell this data to advertisers - if you’ve ever found yourself randomly receiving emails from companies you’ve never heard of before, this is why. However, for a doxxer it could be an easy way to start building a detailed profile of their target.

How Might Doxing be Used Against Your Organization?

For organizations to be successful with their media strategies they necessarily need to share relevant information and regularly engage with their customers through social media channels. This provides a substantial opportunity for doxxers.

By combining publicly-available data with basic attack techniques, such as phishing campaigns or credential stuffing, malicious actors can uncover large quantities of supposedly secure data. For consumers, exposed information could lead to identity theft or public shame. Meanwhile, companies face the prospect of large-scale reputation damage or lost revenue if proprietary project briefs or intellectual properties are leaked to the public.

Additionally, doxing can be used as an incentive to expedite the resolution of ransomware attacks. This is where the cyber attacker threatens to release documents or information to the public should their target not pay the ransomware fee promptly. This adds to already serious financial implications.

How Can you Prevent Doxing?

Unfortunately, it's nearly impossible to completely remove personally-identifying information from the internet, especially parts which are part of public records. Still, there are some tips to reduce your attack surface.

Keep your profiles private 

People and organizations do have a lot of say as to what gets published on the internet. Make sure to practice general data privacy best practices.

• Avoid posting identifying information

• Keep all social media settings at the most private level, and don't accept friend requests from people you don't know

• Change the settings on Office and your phone's photo app so personal info isn't embedded in those files

• Use a "burner" email address for signing up for accounts when possible.

• Set the ‘whois’ records on any domains you own to private

• Ask Google to remove personally available information about you, and request the same from data broker sites

Implement Safe Browsing Measures

These steps are good internet hygiene in any case, but can also prevent a breach that can lead to your info being exposed to a potential doxxer:

• Use a VPN, especially when using insecure public Wi-Fi networks

• Switch to a secure email system with built-in encryption

• Vary your usernames and passwords

Self-Doxing

Humans remain the weakest link in the security chain. In most cases, malice isn’t the problem or the intent when someone lets a threat actor in. Instead, employees overshare personal data on corporate platforms by accident or use insecure third-party applications. In both cases, however, following the breach and identifying the potential compromises is difficult when IT teams start from the side of defenders. 

By flipping the script and looking at your organization from the view of potential doxxer it becomes easier for IT and security teams to spot key areas of weakness. They can then develop strategies and staff training programs to protect against them.

Final Words

Doxing represents a growing threat to organizations and individuals. However, by self-doxing with security intelligence gathering strategies, security teams can create accurate attack surface maps. With this intelligence, they can then enhance threat modelling and deliver actionable insights to staff to reduce overall risks.

Using OSINT software like Signal you can learn about potential threats as or before they occur, learn about potential exploits targeting your organization, and self-dox to help identify weaknesses and shore-up defences.

How Machine Learning is Changing Modern Security Intelligence

A key challenge facing modern security teams is the explosion of new potential threats, both cyber and physical, and the speed with which new exploits are taken advantage of. Additionally, in our globalized world threats can evolve from innumerable sources and manifest as a diverse range of hazards.

Because of this, security teams need to efficiently utilize automation technology and machine learning to identify threats as or even before they emerge if they want to mitigate risks or prevent attacks.

Artificial Intelligence in the Cyber Security Arms Race

Today, AI and machine learning play active roles on both sides of the cybersecurity struggle, enabling both attackers and defenders to operate at new magnitudes of speed and scale.

When thinking about the role of machine learning for corporate security and determining the need, you first need to understand how it is already being used for adversarial applications. For example, machine learning algorithms are being used to implement massive spear-phishing campaigns. Attackers harvest data through hacks and open-source intelligence (OSINT) and then can deploy ‘intelligent’ social engineering strategies with relatively high success rate. Often this can be largely automated which ultimately allows previously unseen volumes of attack to be deployed with very little effort.

Another key example, a strategy that has been growing in popularity as the technology evolves, making it both more effective and harder to prevent, is Deepfake attacks. This uses AI to mimic voice and appearance in audio and video files. This is a relatively new branch of attack in the spread of disinformation and can be harnessed to devastating effect. For example, there are serious fears of the influence they may bring to significant future political events such as the 2020 US Presidential Election.

These are just two of the more obvious strategies currently being implemented in a widespread fashion by threat actors. AI supported cyberattacks though have the potential to go much further. IBM’s DeepLocker, for example, describes an entirely new class of malware in which AI models can be used to disguise malware, carrying it as a ‘payload’ to be launched when specific criteria are met - for example, facial recognition of its target.

Managing Data Volumes

One of the primary and critical uses of AI for security professionals is managing data volumes. In fact, in Capgemini’s 2019 cybersecurity report 61% of organizations acknowledged that they would not be able to identify critical threats without AI because of the quantities of data it is necessary to analyze.

“Machine learning can be used as a ‘first pass’, to bring the probable relevant posts up to the top and push the irrelevant ones to the bottom. The relevant posts for any organization are typically less than 0.1% of the total mass of incoming messages, so efficient culling is necessary for the timely retrieval of the relevant ones.” - Thomas Bevan, Head Data Scientist at Signal.

Without the assistance of advanced automation softwares and AI, it becomes impossible to make timely decisions - impossible to detect anomalous activity. The result of which is that those organizations who don’t employ AI and automation softwares for intelligence gathering often miss critical threats or only discover them when it’s too late.

Signal OSINT and Machine Learning

Signal OSINT platform uses machine learning and automation techniques to improve data collection and aggregation. The platform allows you to create targeted searches using Boolean logic, but it is our machine learning capabilities which allow us to go beyond Boolean keyword searches. 

“By recognising patterns in speech and relations between commonly used words, one can find examples of relevant posts even without keywords. While phrases like ‘I’m gonna kill the boss’ can be picked up by keywords easily, keyword searches alone struggle with more idiomatic speech like, ‘I’m gonna put the boss six feet under’, and will incorrectly flag posts like ‘Check out the new glory kill animation on the final boss’. Machine learning, given the right training data, can be taught to handle these sorts of examples,” says Thomas Bevan.

Signal continuously scans the surface, deep, and dark web and has customizable SMS and Email alert capability so that security teams can get real-time alerts from a wide array of data sources such as Reddit, 4Chan, 8Kun etc. Additionally, Signal allows teams to monitor and gather data from dark web sources that they would otherwise be unable to access either for security reasons or because of captive portals.

Finally, the software allows users to analyze data across languages and translate posts for further human analysis. There are additional capabilities, such as our emotional analysis tool Spotlight, which can help indicate the threat level based on language indicators.

Complementing AI with Human Intelligence

In order to stay ahead of this rapidly evolving threat landscape, security professionals should be using a layered approach that pairs the strategic advantages of machine learning to parse through the vast quantities of new data with human intelligence to make up for current flaws in AI technology.

Machines have been at the forefront of security for decades now. Their role though is evolving as they get passed the heavy lifting, allowing analysts and security professionals to analyse hyper-relevant data efficiently. 

Why organizations need threat intelligence tools as part of their security defences

What is Threat Intelligence?

Those very same technologies that have allowed globalization, which have brought us all closer together and enabled organizations and brands to achieve the current growth and success they enjoy today, have simultaneously brought with them increased risks. These risks come in the form of increased vulnerabilities and exploitable attack vectors for cyber attackers. Threat intelligence is all about gathering data and knowledge to combat and mitigate these threats. 

Threat intelligence provides organizations with information and context required to effectively predict and even prevent cyberattacks. Additionally, it helps inform security teams of the best practice for both preventative measures and response measures to ensure if there is a cyberattack the resulting costs are minimal. 

In short, threat intelligence is the gathering of evidence-based knowledge to inform action-oriented preventative and reactionary responses to an ever-evolving cyber threat landscape.

The Importance of Threat Intelligence

Threat actors are increasingly persistent, and their persistence pays off. Even the most dedicated professionals can’t help but struggle to keep abreast of every new cybersecurity development. New exploits are constantly being discovered or developed and strategies such as social engineering are increasing in complexity. Security teams need up to date data and intelligence on evolving threats if they are going to be able to develop effective responses.

Additionally, within the corporate world one of the key buzzwords of the last two decades has been “accessibility”. Accessibility to data means organizations have necessarily become reliant on digital processes and almost everything is stored on the cloud. Unfortunately, while accessibility is essential to developing efficient processes, and effectively using big data, it also increases the number of threat vectors that attackers can exploit. According to the IBM 2020 data breach report the longer a data breach goes undetected the more expensive it ends up being for the organization. Primarily then, threat intelligence gathered using tools like Signal OSINT can help organizations detect data breaches earlier, mitigating the eventual costs both reputational and monetary.

The final reason that threat intelligence plays such a pivotal role in today’s security is the distinct lack of skilled cybersecurity professionals. Threat intelligence is a time-consuming business that requires a skilled deft hand to manage. The best threat intelligence solutions use machine learning to automate data collection, then filter and structure data from disparate sources to present only hyper-relevant information to a skilled security team for final analysis. The security team can then use this data to create effective actionable plans based on evidential knowledge. This approach optimizes the performance of both the cybersecurity professional and the intelligence tools being used.

Threat intelligence is actionable — it’s timely, provides context, and is able to be understood by the people in charge of making decisions.

Use Case Examples for Threat Intelligence 

Threat intelligence can be used in a diverse range of strategies which makes it an essential tool for security teams in any organization. It’s most immediate value is in helping prevent an attack by gathering intel on threats in real-time, however, it’s also useful for a broad scope of activities such as managing vulnerabilities, informing decision making, and responding to attacks as or after they happen.

Prevent an attack

From the time that a vulnerability is found to the time an exploit targeting that vulnerability is available for threat actors is shortening. Security professionals need to know about the vulnerability fast so that they can implement a patch and prevent it from being exploited.

Respond to a Data Breach

Data breaches are costly and often go unnoticed. With the right threat intelligence tools you can determine when a data breach happens fast and take suitable actions to mitigate the costs of any following repercussions.

Manage a Vulnerability

The approach of “patch everything, all the time” is impractical and will likely see organizations fall behind - leaving more serious vulnerabilities open for longer. Threat intelligence can help security teams effectively manage vulnerabilities by giving the salient data to allow them to prioritize patches based on actual risk. 

Risk Analysis

This leads on nicely from the last point. Threat intelligence can help security teams determine the actual risks associated with potential vulnerabilities or attacks by providing additional contextual information. For example, threat intelligence can help security professionals  answer the following questions:

• Which threat actors are using this attack, and do they target our industry?

• How often has this specific attack been observed recently by enterprises like ours?

• Which vulnerabilities does this attack exploit, and are those vulnerabilities present in our enterprise?

• What kind of damage, technical and financial, has this attack caused in enterprises like ours?

Fraud Prevention

Fraud can encompass anything from a fraudulent use of your brand, data, or even impersonation of your employees. For example, an individual might impersonate a doctor and sell fake versions of your prescription medication online.

Incident Response

Having the ability to gather and filter through threat intelligence from across the surface, deep, and dark web in real-time allows security teams to effectively and appropriately respond to incidents as they are happening.

How can Signal threat intelligence improve your organization’s security?

Signal allows our customers to analyze emerging global trends, detect threats in real-time, and then form appropriate security strategies to counter these potential threats as or even before they fully reveal themselves.

One of the key issues that security teams and analysts face is the sheer amount of noise that might surround their brand. Invariably much of this noise is irrelevant to their purposes, however, some of it will be bad. This is why Signal assists with advanced filters with boolean logic as well as features such as our emotional analysis tool.

How Can Organizations Combat Increasing Cybersecurity Gaps due to Remote Working During COVID-19?

Whether they like it or not, many organizations have been forced to adopt work from home practices to continue operating. Working from home isn’t new. In fact, between 2005 and 2017 the numbers of people that were able to work from home grew 156%. However, it has generally been seen as a bonus rather than a given and more traditional workplaces have been resistant. 

Despite the fact that 49% of office workers have never experienced working from home before, this experiment has largely been a success. Empowered with communication tools like Slack, Microsoft Teams, Google Hangouts. and Zoom, teams have had deep connectivity even from their own living rooms and many organizations have actually seen increased productivity.

Even so, the challenges of working from home are enormous and are invariably compounded by technological difficulties and poor home security practices.

Security teams, in particular, are feeling the pressure. With numerous workers now operating outside the corporate network security controls, new attack vectors have been opened up which are being exploited by cybercriminals.

Cybercriminals Taking Advantage of the Pandemic

Several security providers have put together data sets which show clear spikes in malicious activity since the beginning of the pandemic. McAfee created its own coronavirus dashboard which shows malicious detections quickly growing from the hundreds into the thousands over the last six months. The most common threat type has been Trojans with Spain and the US being clear outliers in the number of threats detected.

As of August, there were nearly 2 million malicious detections against over 5,500 unique organizations. McAfee go into detail about the families and types of attacks that they’ve seen a spike of cases in since the pandemic began.

WFH challenges for security teams

We’ve established that cybercriminals are taking advantage of the security breaches created by a sudden adoption of working from home but what is it exactly that makes working from home lees secure and what exactly are the security flaws threat actors are targeting?

Working from home doesn’t necessarily mean working from home, it could also mean working from anywhere and many workers have already figured that out. This means workers can (in theory) escape their houses and head out to cafes, restaurants, libraries or other public spaces with free WiFi networks. Zoom, with its virtual background feature, has incidentally supported this. The key issue with this is when workers operate on unsecured open networks. 

Ultimately security professionals have to try and ensure device security and data protection in the work from anywhere model - a challenge made significantly harder with over 50% of employees using their own devices during this period. IT teams have tried to make the security transition easier, with some 70% increasing VPN use among employees, however, 1 in 4 workers according to the Morphisec report were unfamiliar with their company’s security protocols.

This challenge for security professionals has resulted in the majority of security professionals seeing a sizeable increase in workload since their companies began corporatewide remote work. And while most of the transition to WFH went smoothly, respondents reported an increase of security incidents, with the top issues including a rise in malicious emails, non-compliant behavior by employees and an increase in software vulnerabilities.

What can be done to improve WFH security?

Security teams have had years to develop best practices for combating the ever-evolving cyber threat landscape. The sudden move to work from home though has shifted power away from them and brought a greater reliance onto workers who simply do not have the expertise to maintain proper cybersecurity protocols. 

Worryingly, 20% of workers said their IT team had not provided any tips as they shifted to working from home. This has opened exploitable attack vectors and introduced new challenges for security professionals. This though isn’t to say that there is nothing that can be done.

Step 1: Control the WFH Environment

This is all about educating employees about best practice and the reasons for these practices when working from home. For example, informing them not to use open networks.

Step 2: Control the WFH Computer

It’s a good idea to supply the computer being used so that you can install the proper security softwares and control access to sites which might offer security risks as well as maintaining control over permissions.

Step 3: Improve your Phishing Responses 

The crossover between home life and work life extends beyond the location. People are more likely to spend time on social media networks and working on private projects than they would be if they were in the office. This opens them up to more phishing campaigns so it’s important they know how to avoid falling for them.

Step 4: Restrict Remote Access to Sensitive Documents and Data

Lockdown permissions and access to sensitive documents and data. If they really need access they can communicate this need with you directly and you can ensure it is done securely and safely. 

Step 5: Monitor Surface, Deep and Dark Web for Emerging Cyber-Threats

Use an OSINT tool like Signal to monitor for cyber threats, planned attacks and data breaches.

Step 6: Encourager VPN Usage

VPNs are a simple and easy way to improve security. It’s worth ensuring the company has a quality VPN service that doesn’t slow a users internet connection unnecessarily as this might persuade workers to turn it off.

Step 7: Don’t Allow Split-Tunnels

Split-tunnelling allows a user to access networks through both the encrypted VPN service and a potentially unsecure network simultaneously.

The Role of Threat Intelligence for Improving Work From Home Cybersecurity

One of the key benefits of using an OSINT solution like Signal is the ability to create customized searches with Boolean logic to uncover hyper-relevant threats in real-time with SMS and email alerts. 

Ways that this has been used in the past to improve cybersecurity include:

• Early detection of data breaches. The average cost of a data breach in 2020 is $3.86 million. The earlier you catch a data breach the faster you can take action to mitigate the associated financial and reputational damage.

• Discovery of new cyberattack strategies, exploit kits, phishing tactics which were talked about or for sale on the dark web.

• Organizations have uncovered attacks that are yet to be carried out. This is true for both physical attacks against an asset or person as well as cyberattacks. For example, details of a phishing strategy and the targets within the organization were discovered after being talked about in a darknet forum. 

• Monitor employee online activity. For example, this can allow security teams to identify employees who have been targeted and even blackmailed by cyber attackers for access to company data.

What Security Professionals need to know about Dark Web Forums

The dark web isn’t inherently bad or evil. It’s not illegal to be anonymous on the web. However, the unfortunate truth is that there are plenty of people who are willing to take advantage of the anonymity lent by the dark web and to undertake some form of illicit activity.

Cybercriminals use the dark web as a means to communicate about all manner of activities, from planning cyberattacks to the selling of illegal goods or stolen data.

On top of this, with distrust growing towards governing bodies and large corporations around data privacy dark web communities are thriving. More people are becoming familiar with the dark web for both legitimate and illegitimate reasons, a fact that should cause security professionals increasing concern.

On the flip side, many security professionals actually shy away from the dark web. It is an online region surrounded by an ether of mystery and myth. However, while certain parts of the dark web should only be accessed with the utmost skill and caution, the basics of the dark web need to be understood by all members of the security community.

The difficulties of accessing dark web forums

There are numerous challenges that security professionals face when they come face to face with the dark web. The first of which is actually finding the dark web forums where illicit activity is taking place.

The first step to locationg dark websites is through various directory lists. These easy to locate sites and forums, however, are unlikely to be where the really important things are happening. Instead it’s more likely to be filled with amateurs and more innocent activity. Additionally, these lists often become outdated quickly as dark web domains change frequently.

In order to locate more relevant darknet forums for the purposes of security research, there are strategies which can be employed, for example, snowball sampling.

Snowball sampling is a method which involves creating a web crawler that takes a root URL and crawls the website for outgoing links. Generally, this will then return a large number of dark web URLs. This works particularly well for dark web forums as people often link to other sites in comments or posts. Done incorrectly though could draw attention to your bot and have the admin block you.

The dangers of accessing dark web forums

Accessing the dark web should be done with care and caution. It is in some ways like the last frontier, the wild west. It provides a training ground for new techniques and strategies for experienced and inexperienced hackers alike. For a security professional, getting to know these new techniques is vital for the efficacy of your security strategies.

A few key safety concerns and the dangers of the dark web are as follows:

• Breaking the law. Law enforcement officials operate on the dark web to catch people engaged in criminal activity. Like others on the dark web, law enforcement can do their work under a cloak of anonymity. It’s important to remember that you can be prosecuted for things you do on the dark web and thus to behave in an appropriate and legal manner.  

• Viruses. Unsurprisingly a lot of hackers on the dark web would be more than willing to turn their talents and attention to you should you accidentally cross them. Some websites will infect your device with viruses and any and all links or downloads should be viewed with suspicion. There are a lot of viruses to watch for, from ransomware to spyware and everything in between. Additionally, if you do click any links you may be taken to the material you don’t want to see that many people would find disturbing. 

• Webcam hijacking. It’s smart practice to cover your webcam with a piece of tape or plastic when you’re not using it. This is because some people may attempt to gain access to your device’s webcam by using a remote administration tool (RAT). The risk of this happening increases exponentially when you enter the dark web.

Remember: You use the dark web at your own risk and you should take necessary security precautions such as disabling scripts and using a VPN service.

Why do security professionals need to surveil dark web forums?

We’ve talked about the dangers and difficulties of accessing and finding relevant dark web forums for security research. Why though should accessing these dark web forums be a priority for security professionals and how can one effectively monitor these forums for potential threats?

Identify new hack strategies. 

The dark web is where many cyber criminals go to learn as well as to purchase things like exploit kits. Monitoring the dark web, being able to investigate and understand the methods and mindsets of hackers is essential to enable security professionals to develop counter strategies.

Discover physical threats or plans against your organization or executives.

Terrorist organizations, violent far-right dissenters, and others who intend to commit or openly discuss violence against others can be found on dark web forums. One example of this is the shooting which took place in a mosque in New Zealand on the 15 March 2019 which killed 51 people.

This attack was talked about before and during the attack on forums such as 8chan. Pictures of the weapons that would be used were shared along with a 74 page manifesto. Conversations around the event appeared with numerous like-minded individuals actively in support.

This is an extreme, worst-case scenario. But it absolutely highlights the necessity for security teams to have the tools to effectively monitor dark web forums.

Listen and filter noise around your organization’s name. 

There is a lot of noise on the internet. Inevitably some of it may be about your organization and it’s more than likely that not all of it will be good noise. Because of the nature of dark web forums, there is an increased likelihood of discovering negative noise about or relating to your organization.

With the right tools, such as Signal paired with our emotional analysis tool Spotlight, you can identify persons of interest and more closely monitor future activity around them. 

Additionally, discussions around stolen data for sale, as well as things like exploit kits are often discussed on the dark web. Identifying these threats as soon as they appear will allow you to take appropriate action to mitigate these threats and reduce any potential damages.
