Case Study #1: A Medical Practice is Hit with Ransomware

Medical practices are a prime target for ransomware attacks due to the amount of valuable data they hold. In addition to a potential ransom payment, personal data and credit card information can be sold by cybercriminals on dark web marketplace forums. Small individual and group practices may also lack comprehensive cybersecurity, making them an easy target for malicious attacks.

Ransomware frequently enters your system via a virus on an email attachment. It searches on the computer for data to encrypt and then spreads to other computers and files on your network. The virus encrypts your data, making it unreadable and unusable. The attacker then demands an untraceable digital payment in exchange for a decryption key. The data may or may not be released after payment.

The Cybersecurity Challenge

The billing department of a medical practice received a ransomware demand on their desktop screen. The practice manager contacted their IT support person. IT shut down the network and began investigating. The practice had no access to anything on their network and switched to handwritten paper records for scheduling, clinical notes and prescription writing.

The IT support provider was not able to solve the issue, and needed cybersecurity expertise to investigate and halt the attack. Cybersecurity experts determined that the virus had entered the system as an email attachment that resembled an invoice. Once it was on the computer, the virus searched for data to encrypt and then spread to the rest of the network.

Fortunately, the practice had offsite physical backup of most of the records and did not need to pay the requested ransom. The backup data was requested from storage, shipped, cleared of any remnants of the virus and then reloaded back onto the network. Unfortunately, recovery took more than a week due to the method of backup and created unexpected additional charges for recovery services.

Recovery Solutions and Lessons Learned

This practice averted devastating failure by having backup data available to reload. The cybersecurity team provided disaster response, mitigation and recovery services and then implemented updates and additional protections to lessen the risk of cyberattacks and data breaches. Many of the security products in use at the practice were unpatched and outdated and had not been reviewed for years. The team conducted a full assessment and submitted a comprehensive plan. Here are some of the changes, updates and improvements put in place:

Technical Controls:

• Email filters
• Antivirus software update
• Local and cloud data backup
• Firewall updates
• Administrative access restrictions
• HIPAA policy and procedure controls addressed

Employee Awareness Training:

• Recognizing suspicious emails
• Downloading from unfamiliar websites
• Recognizing phishing attempts
• Using approved portable storage devices
• New employee HIPAA security and privacy training
• Physical safeguards for data
• Updated policies and procedures enacted

Disaster Response and Business Continuity Planning:

• Data backup plan
• Backup testing
• Disaster recovery plan

Monitor Staff Usage and Practices:

• Phishing assessments

Case Study #2: Phishing Attack and Employee Password Compromise

Phishing attacks are a type of social engineering attack designed to steal data, login credentials and credit card numbers. Cybercriminals masquerade as a fellow employee or other trusted entity and trick users with a malicious link. The link may be used to spread ransomware in the system or get information such as passwords and logins or credit card numbers. These attacks can have devastating results, including financial loss and damage to credit and reputation, and can also be part of a scheme to gain access to a larger partner company’s data.

The Cybersecurity Attack Challenge

An employee at a regional grocery retailer received an email from his coworker, informing him that she was sharing a document with him. He had received documents from her before, but wasn’t expecting one that day. The email was vague and had no project details, which was unusual. He clicked the link, and it opened to what looked like the usual file-sharing site the company typically uses. He was asked to enter his login and password, then got an error message. He tried again and got another error message.

The employee contacted his manager to request a password reset and report trouble downloading a shared document. He also mentioned that he called the coworker, and she said she had not sent him anything. The manager was suspicious that this was likely a hacking incident.

Remediation, Recovery and Awareness Training

The cybersecurity team was contacted and immediately reset everyone’s passwords. They verified that the email was a phishing attempt using a fake site. They also checked security settings for any suspicious rule changes, and informed everyone at the company about the incident. Two-factor authentication for signing into accounts was implemented to alert users to any new sign-ins from their account. The security team also scheduled security awareness training and testing for this company. Employees who receive comprehensive training are better able to spot phishing attempts by learning techniques such as checking the URLs of any suspicious emails and verifying with the sender directly about anything that appears unusual.

Thankfully, the employees alerted management right away, which helped prevent data theft and compromise. Management made the decision to engage the cybersecurity team to respond quickly, halt the attack and verify no other systems were compromised. The phishing attack alerted upper management to the need for additional security training to educate and reduce cyber risk in this area.

Case Study #3: Infrastructure Monitoring and Weak Passwords

An industrial thermostat manufacturer noticed unusual activity on the network. The cybersecurity team examined logs that indicated someone was logging in to networks and servers at unusual times using company credentials. No evidence of malware or Trojans was found. The cybercriminal logged in at will using a very weak, common password. After changing the password, the team investigated to determine whether anything was stolen and whether the attacker was still getting into the system.

The cybersecurity experts were able to remotely image the servers and preserve the forensic data of the incident and remediation for reporting and insurance purposes. The investigation revealed that the cybercriminals stole a large amount of data by converting it into an image and hiding it on the website. They could revisit at any time to retrieve the image without logging in.

Incident Response and Recovery Objectives

The data stolen was not considered confidential or protected by regulations, so no customers or regulators had to be notified. The incident did serve to highlight cyber defense weaknesses in the company’s daily practices and infrastructure monitoring. A remediation plan was put in place by the cybersecurity consultants that included these items:

• Update security policy and regularly test for compliance
• Conduct regular employee security awareness training
• Regularly change strong passwords
• Monitor administrative accounts for unusual usage
• Monitor network traffic and data access
• Protect and monitor infrastructure security

Cyber Case Study: Marriott Data Breach

by Kelli Young | Oct 11, 2021 | Case Study , Cyber Liability Insurance

In the final months of 2018, Marriott International—a hospitality company that oversees one of the biggest hotel chains in the world—discovered that cybercriminals had compromised its guest reservation system. This Marriott data breach exposed the personal information of hundreds of millions of customers from various countries who had made bookings with the company’s Starwood properties over the past several years. As a result of the incident, Marriott faced significant recovery expenses, legal ramifications and reputational damages.

This breach—which ultimately stemmed from existing security vulnerabilities that carried over during Marriott’s 2016 acquisition of Starwood—has since become known as one of the largest cyber incidents the world has ever seen, showcasing the importance of prioritizing cybersecurity during merger and acquisition (M&A) events. In hindsight, there are various cybersecurity lessons that organizations can learn by reviewing the details of this incident, its impact and the mistakes Marriott made along the way. Here’s what your organization needs to know.

The Details of the Marriott Data Breach

In 2014—two years before Marriott even acquired Starwood—the latter company’s guest reservation system was infiltrated by cybercriminals via remote access trojan (RAT). Put simply, a RAT is a harmful computer program that grants the perpetrator unauthorized administrative control of their victim’s technology. A multitude of digital vulnerabilities at Starwood’s properties could have contributed to the success of the cyber-criminals’ RAT. Namely, these properties were using outdated versions of Windows Server across their computer systems and had left their remote desk protocol (RDP) ports open to the internet. Despite this intrusion within the guest reservation system, Starwood was unable to detect the cybercriminals’ activity—allowing them to remain unnoticed.

Moving forward to September 2016, Marriott officially acquired Starwood. During the acquisition process, Marriott failed to complete a detailed cybersecurity audit of Starwood’s networks and technology. As such, Marriott was also unable to identify the cybercriminals’ activity within Starwood’s guest reservation system—permitting them to stay undetected throughout the acquisition. Additionally, Marriott didn’t discover that Starwood had been further targeted by separate attackers in an unrelated incident during 2015, leaving its workplace devices infected with malware.

Rather than adopt uniform networks and technology following the acquisition, Marriott allowed Starwood properties to move forward with their current operations—thus utilizing a compromised guest reservation system and malware-ridden devices. Marriott also began migrating information from several databases housed within Starwood’s guest reservation system. This information included a variety of customers’ personal details—such as names, addresses, phone numbers, email addresses, passport numbers and credit card numbers.

While the information in these databases was encrypted, the cybercriminals were eventually able to locate their associated decryption keys and subsequently unlock the information. From there, the cybercriminals began exfiltrating the information. After transporting this information, the cybercriminals then re-encrypted it in an effort to remain undetected within the system.

In September 2018—a full two years after the acquisition—Marriott finally identified the breach due to a system security alert. Upon this discovery, Marriott reported the incident to law enforcement officials and consulted forensic specialists to launch an investigation. On Nov. 30, 2018, Marriott revealed the details of the breach to the public in an official statement. At this time, Marriott confirmed that the personal information of nearly 500 million customers around the world—including the United States, Canada and the United Kingdom—had been compromised.

The Impact of the Marriott Data Breach

In addition to exposed data, Marriott faced several consequences following the large-scale breach. This includes the following:

Recovery costs Marriott incurred nearly $30 million in overall recovery expenses as a result of the breach. This total includes costs related to investigating the cause of the breach, notifying impacted customers of the breach, providing these customers with year-long access to security monitoring software, developing an international call center related to the breach and implementing updated cybersecurity measures to prevent future incidents.

Reputational damages Apart from recovery costs, Marriott also received widespread criticism for its cybersecurity shortcomings after the incident. In particular, the media and IT experts scrutinized Marriott’s failures to perform its due diligence on Starwood’s existing security vulnerabilities prior to the M&A process and detect the cybercriminals’ activity after the acquisition was finalized—essentially allowing the cybercriminals to access and exfiltrate customers’ personal information for nearly four years. Consequently, Marriott’s stocks dropped by 5% almost immediately after it announced the details of the breach. What’s more, the company is estimated to have suffered over $1 billion in lost revenue due to diminished customer loyalty following the incident.

Legal ramifications Lastly, Marriott encountered costly legal ramifications from various avenues because of the breach. Since the incident affected individuals from the United Kingdom, the Information Commissioner’s Office fined Marriott over $120 million for violating British customers’ privacy rights under the General Data Protection Regulation. In North America, Marriott was met with multiple class-action lawsuits after announcing the breach—one of which requested $12.5 billion in damages, or $25 for every impacted customer.

Lessons Learned

There are several cybersecurity takeaways from the Marriott data breach. Specifically, the incident emphasized these important lessons:

RDP ports require proper safeguards. Exposed RDP ports were another potential culprit of this costly incident. Although RDP ports are useful workplace tools that permit employees to connect remotely to other servers or devices, leaving these ports open can allow cybercriminals to leverage them as a vector for deploying malicious software or other harmful programs (including RATs). That being said, RDP ports should never be unnecessarily left open to the internet. Virtual private networks (VPNs) and multi-factor authentication protocols can also be utilized to help keep RDP ports from being exploited by cybercriminals.

Cybersecurity must be considered during M&A events. Marriott neglecting to prioritize cybersecurity amid its acquisition of Starwood proved detrimental in this breach. Primarily, Marriott should have diligently assessed Starwood’s IT vulnerabilities throughout the M&A process. Further, Marriott should have ensured an effective cybersecurity infrastructure between the combined companies once the acquisition took place. Especially as cyber incidents continue to surge in both cost and frequency, cybersecurity should be top of mind during any M&A activity. In particular, each company involved in the M&A process should be carefully evaluated for potential cybersecurity gaps. A proper plan for rectifying or—at the very least—mitigating these exposures should be developed prior to the finalization of the M&A event. In many cases, it can also be advantageous for merged companies to adopt shared digital processes and security policies in order to maintain uniform defense strategies against cybercriminals.

Effective security and threat detection software is critical. A wide range of security and threat detection software likely could have helped both Starwood and Marriott identify and mitigate this breach in a much faster manner—thus reducing the resulting damages. Although this software may seem like an expensive investment, it’s well worth it to minimize the impacts of potentially devastating cyber incidents. Necessary software to consider includes network monitoring systems, antivirus programs, endpoint detection products and patch management tools. Also, it’s valuable to conduct routine penetration testing to determine whether this software possesses any security gaps or ongoing vulnerabilities. If such testing reveals any problems, these issues should be addressed immediately.

Proper coverage can provide much-needed protection. Finally, this breach made it clear that no organization—not even an international hospitality company—is immune to cyber-related losses. That’s why it’s crucial to ensure adequate protection against potential cyber incidents by securing proper coverage. Make sure your organization works with a trusted insurance advisor when navigating these coverage decisions.

State Cybersecurity Governance Case Studies

In recognition of the importance of governance in addressing cyber risks, the Cybersecurity and Infrastructure Security Agency's (CISA) Cybersecurity Division and the National Association of State Chief Information Officers (NASCIO) partnered to develop a State Cybersecurity Governance Report and series of State Cybersecurity Governance Case Studies exploring how states govern cybersecurity. The Homeland Security Systems Engineering and Development Institute (HSSEDI), a DHS owned Federally Funded Research and Development Center (FFRDC), developed the case studies. The report and case studies identify how states have used laws, policies, structures, and processes to help better govern cybersecurity as an enterprise-wide strategic issue across state governments and other public and private sector stakeholders. The report and case studies explore cross-enterprise governance mechanisms used by states across a range of common cybersecurity areas and offer insight on trends and concepts useful to other states and organizations that face similar challenges.

How AI Is Being Used to Improve Cybersecurity for Businesses of All Sizes Discussing the role of AI in cybersecurity, the challenges that cybersecurity teams are facing and future trends that governments and businesses need to be aware of.

By Jessica Wong Edited by Chelsea Brown Jul 17, 2024

Key Takeaways

• Artificial intelligence plays a dual role in cybersecurity as a protector and an antagonist.

Threat detection and data protection are two cornerstones of effective cybersecurity, and AI can enhance both.

• Governments and businesses must ensure AI-based protection, detection and resolution outpace the growth of cybercrime in the next few years.

Opinions expressed by Entrepreneur contributors are their own.

Cybercrime is on the rise across the United States and globally. Over the past decade, online crimes caused more than $12 billion in damage , a twelve-fold increase compared to 2015. Where companies used to fear physical threats such as bank robberies, they are now guarding against far less visible attacks.

As the world's reliance on digital technologies grows, artificial intelligence (AI) has the potential to enhance cybersecurity measures for businesses of any size.

The role of AI in cybersecurity

Cybersecurity has changed dramatically over the past decade. Ten years ago, more than one in five cybersecurity incidents involved paper records. This year, the figure has dropped to an almost negligible 2%. Cyber attacks involving paper records have been replaced by phishing incidents, which nearly doubled throughout this time.

The growth of ransomware attacks is even more obvious. Virtually unknown in 2015, they now account for nearly one in three cyber attacks in the U.S. At this time, AI plays a dual role in cybersecurity as it is used by both perpetrators of online crimes and those looking to secure data. The World Economic Forum has spoken of an AI arms race .

Chief Information Security Officers (CISOs) around the world are leveraging technologies like machine learning and deep learning to stay several steps ahead of their adversaries. Thanks to its fundamental capacity to analyze huge amounts of data, AI allows CISOs and their teams to monitor network activity and spot anomalies early. Identifying suspicious behavior or fraudulent activity early becomes not only easier but may be the key to effectively preventing monetary and other damage.

At the same time, utilizing AI frees up analysts' time, allowing them to concentrate on more strategic activities.

Key AI technologies in cybersecurity

Amazon GuardDuty is an AI-based threat detector that uses machine learning (ML) and Amazon Web Services' (AWS') own integrated threat intelligence to protect AWS accounts and associated data. The software detects suspicious activities such as the removal of AI security guardrails and investigates those faster than human analysts could. Users can also automate threat remediation.

In addition, Amazon GuardDuty protects against ransomware uploads and scans for the presence of malware, including cryptocurrency-related threats.

IBM Watson for Cybersecurity is another heavy hitter in AI-based threat detection. Watson analyses security data from different sources, including security alerts and logs. By combining information gathered in more than one place, Watson can detect threats the non-AI security software may have missed. The company's range of IBM Security® solutions offers more customized tools to meet the cybersecurity needs of today's businesses.

Challenges and limitations

One of the challenges of using AI in cybersecurity is the speed at which the field is expanding. Research firm Gartner predicts that by 2026, four out of five businesses will have used generative AI -enabled applications. By comparison, just one year ago, only 5% of all enterprises were employing these emerging technologies.

Given the rate of acceleration, one of the challenges of cybersecurity professionals is to safeguard these projects. According to IBM , less than a quarter of generative AI projects are secured adequately right now, leaving three-quarters open to malicious attacks.

Cybersecurity teams are facing internal and external challenges. Externally, cyber attacks are becoming more sophisticated as the volume and value of data grow. Potential attackers no longer need excessive computing power to develop harmful products.

At the same time, teams looking to protect an organization's data are dealing with internal problems like the sheer volume of data and increasingly complex data infrastructures. They also have to balance users' need for access with security concerns.

Case studies

Cyber attacks are not limited to specific verticals. As companies' dependency on data grows, so does the potential of cybercrime. Industrial solutions provider Andritz AG noticed an increase in security breaches in 2020. With nearly 50% of its 27,000-strong workforce relying on remote network access, the company needed to find a solution that protected proprietary information and allowed its teams to continue working.

With customers operating power stations and chemical plants among other applications, cybersecurity breaches could quickly become catastrophic. The team implemented an AI-based solution to visualize threats and neutralize them fast, protecting its employees and clients.

China-based United Family Healthcare (UFH) turned to AI-based cybersecurity solutions when a combination of compliance regulations, external threats and employee behaviors like password sharing put data at risk.

The company needed a solution that streamlined security operations in one central location, allowing a relatively small cybersecurity team to monitor and detect suspicious activities across different locations. Once online, their AI-based system provided an overview of the company's security situation within minutes. The application has also had a positive effect on internal operations, with risks and alarms decreasing since its implementation four years ago.

Future trends

As the use of generative AI continues to expand throughout all verticals and society as a whole, the need for equally powerful cybersecurity will increase.

While it may still be easy to look at cybersecurity as something that may not apply to small businesses, few businesses will be able to overlook cyber threats for much longer. Losing access to an ecommerce website or compromising customer data on social media platforms can threaten a company's future.

As cyber threats evolve and expand their reach, AI-based cybersecurity needs to evolve to detect and neutralize them before damage occurs. In the future, we are likely to see AI-based security elements incorporated into widely used applications such as social media content generation, scheduling tools and more.

When it comes to cybersecurity, AI has a dual role as an antagonist and a protector. Over the coming years, governments and businesses need to ensure that AI-based protection, detection and resolution outpace the growth of cyber threats and cybercrime.
