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. 

12 of the Biggest Ransomware Attacks of 2020

Ransomware is a form of malware which is installed on a victims device or devices with the main objective of seizing and/or locking away sensitive data. As the name suggests in order for a victim to regain access to their data and systems they need to pay a ransom. More often than not, the two options a victim is presented with when they succumb to a ransomware attack is to either rebuild their systems from scratch and potentially have the attacker leak the data online - or pay up.

As such, it’s unsurprising that, in our increasingly digital age with more and more data on the cloud, that the number of attacks and the success of ransomware attacks is on the rise. Approximately 58% of ransomware victims paid in 2020, compared to 39% in 2017.

Ransoms for these kinds of attacks range from a few hundred dollars to thousands or even millions of dollars payable in cryptocurrency such as Bitcoin. In return for the payout, the attackers will release a decryption key allowing the organization to return to business. Certain industries, such as government organizations and hospitals are more susceptible to ransomware attacks due to the nature of the work that they do often being time-sensitive. For example, a ransomware attack crippled a hospital in Germany, leading directly to one patient’s death.  

There are numerous strategies that ransomware attackers employ to gain access to a victims database. One of the most common though is through social engineering tactics, such as phishing emails. Cybercriminals can make these emails look exactly like trustworthy emails from official sources, tricking victims into downloading compromised software onto their device. 

Because of the nature of social engineering tactics, and the evolving cyber threat landscape no organization can ever be fully secure from malware threats. Below we outline 12 of the biggest ransomware attacks that occurred in 2020.

12 Ransomware Attacks that Happened in 2020

1. ISS World 

Estimated cost: $74 million 

In February of 2020 ISS world, a Denmark based company went down due to a ransomware attack. Thousands of employees were left without access to their systems and emails. This cost them an estimated $74 million which includes regaining control of the affected IT systems and re-launching critical business systems. 

2. Cognizant

Estimated cost: $50 million

A ransomware attack on the organization Cognizant in April of 2020 is said to have cost the company over $50 million, potentially as much as $70 million, including legal and consultation costs and data recovery costs, along with the financial loss reflected in their second-quarter earning in 2020.

3. Sopra Steria 

Estimated cost: $50 million

The company Sopra Steria revealed that they were hit by hackers using a new version of the Ryuk ransomware in October.

They estimate that the fallout, including dealing with the various systems that went out of action, is likely to have a gross negative impact on operating margin of between €40 million and €50 million.

4. Redcar and Cleveland Council 

Estimated cost: $14 million

Redcar and Cleveland Council in the UK suffered an attack on their systems in February of 2020 costing the council an estimated $14 million.  The ransomware attack is said to have disrupted the company’s network, tablets, computers, and mobile devices for 3 full weeks. The council announced that in March, that it could take months for a full recovery and estimated the overall costs to be between $14 - $21 million.

5. Software AG

Estimated cost: $20 million

Software AG is the second-largest software vendor in Germany. They were reportedly hit with the Clop ransomware in an attack in October of 2020. The company disclosed that the ransomware attack disrupted a part of its internal network but didn’t affect customer services. The cybercriminal group responsible demanded a $23 million ransom.

7. Travelex

Estimated cost: $2.3 million

It was reported that Travelex the money exchange firm was hit with a file-encrypting malware attack which shut down its internal networks, website and apps for several weeks. Reportedly Travelex paid a ransom of $2.3 million in BTC to the dark actors to regain access to their data and restore services.

8. University of California San Francisco (UCSF)

Estimated cost: $1.14 million

UCSF was targeted by a malware attack which encrypted servers used by the school of medicine impacting students in June of 2020. The ransomware was prevented from travelling to the core UCSF network and causing more damage. The authorities negotiated with the cybercriminals and UCSF ended up paying approximately $1.14 million in ransom of the $3 million demanded. 

9. Shirbit Insurance 

Estimated cost: $1million

After a cyberattack on the Israeli Insurance provider Shirbit in December of 2020 the attackers demanded roughly $1 million in Bitcoin. In order to pressure the company into paying they demanded immediate payment or an increase in the ransom cost, doubling after 24 hours. Additionally, to show they weren’t empty threats they dumped the first 300 records online, again threatening to dump additional records every 24 hours until they received payment.

10. Communications and Power industries 

Estimated cost: $500,000

California-based Communications & Power Industries (CPI) makes components for military devices and equipment, like radar, missile seekers and electronic warfare technology. The company counts the U.S. Department of Defense and its advanced research unit DARPA as customers. Reportedly, CPI paid $500,000 to obtain the decryption key to unlock their servers and return services.

11. Grubman Shire Meiselas & Sacks 

Estimated cost: $365,000

Grubman Shire Meiselas & Sacks is a law firm that specializes in law for those in the media and entertainment industry. Their clients consist of a range of A-list celebrities and, with such high profile individuals on the line, the stakes for them were extremely high. They were targeted and files encrypted by REvil ransomware. The firm agreed to pay an estimated $365,000, however, the attackers started demanding more afterwards and the company has since kept quiet on what it has or is willing to pay.

12. Tillamook County 

Estimated cost: $300,000

Tillamook county in the US was attacked by cyber attackers in January. The attack interrupted their email network, phone systems and website. After exhausting alternative options, they estimated the costs to restore service would cost well over $1 million and take several years and opted instead to pay the $300,000 ransom. 

Keeping your data and organization secure

1. Never click on suspicious links or any links attached in unsolicited emails. 

2. Back up systems and data continuously. Create a separate data-backup in an external hard drive that is not connected to your computer, so that you don’t have to pay the ransom if a ransomware attack happens.

3. Never disclose personal information over the phone or over email. 

4. Educate employees of cybersecurity best practices and social engineering tactics that may be used against them.

5. Limit employee access to sensitive data to reduce attack surfaces.

OSINT Tools and Mitigating Costly Ransomware Attacks

Early warning of data beaches through OSINT tools can help you predict and prevent cyber attacks as well as enable organizations to take mitigating actions faster. While open-source intelligence tools can’t prevent ransomware, they can help organizations reduce the risks and potential damages. 

OSINT tools can be used by organizations to monitor their supply chains, allowing them to learn of potential disruptions in real-time and enabling them to implement contingency plans fast. 

Additionally, organizations can use tools like Signal to monitor for ransomware and malware currently being used. This can help security teams determine emerging threats being used against other organizations in their industry to better inform ongoing cybersecurity best practices.

Ultimately, by using OSINT to monitor darknet forums and market places security professionals are able to learn about the newest strategies being employed, the most recent weaknesses being exploited, and the most current software being utilized. Armed with this knowledge they are much more able to develop effective countermeasures as well as actively prevent ransomware infection.

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 does Darknet Intelligence help us Fight Cybercrime?

Sites on the dark web are marketplaces for emerging cyber threats. As such, these are rich sources of intelligence, often relevant to a broad spectrum of potential targets.

Signal’s AI and emotion analysis paired with customisable alerts allows you to identify potential relevant threats from sites on the dark web to other threat sources, enabling you to more quickly identify, profile, and mitigate risks to your organization.

Cybersecurity Threats from the Dark Web

With enough knowledge, you can create actionable insights. To understand and counter cyber threats we need developed intelligence and actionable insights and details of those threats.

Three of the main forms of threat identified on the dark web are: 

• Physical threats. 

• Data for sale online. 

• Fraudulent activity.

What we know is that the darknet contains difficult-to-locate hacker websites and tools which are the basis of cybersecurity threats. To understand how to counter these cyber-threats, we need to develop intelligence about the details of those threats.

Before we start looking at how that intelligence is gathered, let’s look first at what sort of things we are looking for. 

Content to Look out for on the Darknet

The darknet isn’t itself criminal or illegal. Rather it provides a platform of anonymity which makes it a very attractive prospect for criminals. There have been cases where contract killers have been hired, or terrorist cells have organised attacks.

On top of this, the darknet hosts various items related to cybercriminals as well as the more traditional criminal activities. It is worth noting though that the majority of traffic that goes through Tor browsers is not criminal activity.

1. Malware

You don’t need to be a proficient software coder any longer to become a hacker. Malware, and things like phishing and exploit kits, are freely available to purchase on the dark web if you know where to look.

2. Data for Sale

It’s common to discover stolen data for sale on the dark web. This often includes non sensitive data such as account logins and email addresses which will be used in credential stuffing attacks. However, more concerning is the amount of credit card and PII (Personal Identifiable Information) that can be found for sale.

Read: Mitigating the threat of credential stuffing.

3. Cyber Security Vulnerabilities

Another item hackers and cybercriminals sell on the dark web are “exploits”. These are when exploitable vulnerabilities in a companies security is discovered. Then the cybercriminal sells the exploit to a hacker who can use the information to create tailored malware.

On a positive note, it has been found that the number of exploits for sale on the dark web have declined in recent years. One potential reason for this decline is due to an increasing number of companies offering a bug bounty program. These programs offer a legitimate financial reward to those that discover potential security flaws.

4. Distributed Denial of Service (DDoS) BOts and Tools

Kaspersky has found that cybercriminals are reaping rewards of up to 95% profit by selling DDoS-as-a-service. Cybercriminals offer a sophisticated pricing plan for customers wanting to attack websites. Cheap and dangerous darknet botnets, for sale from $20, can cause havoc.

5. Discussion Forums for Cyber Criminals

Hackers come together on darknet forums to plan, share details, and exchange goods and information. And while the use of a Tor browser grants them anonymity, discovering their conversation allows security teams to potentially spot threats as or even before they are emerging.

What is Darknet Intelligence?

The darknet hosts a huge amount of valuable insights and data that could make all the difference to your security teams success. Understanding the kind of information you are looking for and how the dark web is used by cyber criminals allows you to effectively monitor criminal forums on the dark web and evolve effective plans to counter impending threats.

However, there is one fundamental problem. How do you do efficiently scan or monitor the dark web? 

Due to the nature and structure of the dark web, finding relevant sources, gaining access to criminal forums, and obtaining information is a huge undertaking that requires specialised knowledge. 

Manually Gathering Darknet Intelligence

Skilled security analysts can spend time building up knowledge around darknet based threats, locating relevant forums and gathering access via pseudonyms. Understandably this approach is wrought with difficulties such as:

• Expense.

  A skilled security analyst is expensive, the average salary being over $99,000 a year. And there aren’t that many out there. By 2022 there will be an estimated shortfall of around 1.8 million skilled cybersecurity professionals. 

• Efficiency.

  The darknet is disparate and deep. The names dark web or darknet are themselves misnomers. They suggest that the dark web exists somewhat like the World Wide Web in a state of connectivity. However, many of the websites on the dark web, especially the criminal ones do not want to be found. They aren’t indexed and other sites don’t link to them. Many of them require you to form an account and to be vetted by admin before you can gain access. 

  One individual is going to have an incredibly hard time finding, gaining access to and manually monitoring relevant dark web sites. One solution could be employing a team of security analysts - however, that brings us back to the first point; expense.

• The changing nature of the darknet.

  Sites on the darknet come and go quickly. Again this is especially true for the criminal websites that you would want to be monitoring. This means that anybody wanting to monitor these sites would need to regularly research and find the same sites as well as continuously looking for new ones.

Thankfully, there is an alternative and you don’t need to waste hours of a skilled analysts time trawling through an almost endless see of data in the dark. This alternative requires you to utlize automation tools such as Signal or our recently launched product LERTR. 

Automating Darknet Intelligence with Signal or LERTR

Darknet intelligence-gathering tools work by running automated searches of darknet websites and forums. Using Signal you can create customised alerts filtered via specific keywords, phrases or even locations. We also have a built-in translation tool so that data can be searched across languages and automatically translated into your default language.

On top of this, you can run alerts through our emotional analysis tool to determine how much of a threat any particular alert is. Finally, get our optional Sapphire bolt-on and utilise our skilled data analysts to further refine your results. 

This approach allows your leave your dark web monitoring on autopilot and not only effectively reduce costs but vastly increase the scope of your monitoring ability and the overall amount of hyper-relevant intelligence at your fingertips.

All of this allows you to gather actionable intel in realtime.
