Tackling Cybersecurity in the Legal World – Common Cyber Attacks (Part 1)

As judicial institutions embrace technology, they open doors to innovation but also vulnerabilities. These series of articles delve into the rising threats of cyberattacks on the legal sector, the profound consequences of breaches, and the comprehensive strategies necessary to build resilient defences and safeguard justice in the digital age.

The integration of technology into judicial institutions has revolutionised legal operations, making processes more efficient, accessible, and transparent. From digital case management systems to virtual courtrooms, technology has empowered legal professionals to deliver justice swiftly and effectively. These advancements are ushering in an era of streamlined legal practices, ensuring that justice extends even to the most remote corners.

However, this reliance on digital tools comes with its own set of challenges. While technology enhances efficiency, it also opens doors to vulnerabilities that cybercriminals are waiting to exploit. Judicial institutions, as custodians of sensitive data and critical legal processes, have become prime targets for such cyber-attacks. Yet, rest assured, the solution lies within the same technological framework. Cybersecurity experts are constantly innovating to counter these threats. By employing advanced encryption, AI-driven threat detection, and robust security protocols, judicial bodies can not only secure their systems but continue to innovate with them.

Technology, therefore, is a mixed blessing that offers unprecedented benefits along with significant risks. By proactively addressing potential vulnerabilities, judicial institutions can create a resilient digital infrastructure that upholds the integrity of the justice system. This article delves into the rising threats of cyberattacks on the legal sector, the different ways cybercrime has evolved over the years, and cites real-life examples of threats and attacks that have disrupted operations and businesses around the world.

Understanding Common Cyber Attacks Targeting Legal Institutions

Legal institutions, entrusted with critical client information, confidential case records, and private communications, have become prime targets for cybercriminals. These attackers exploit vulnerabilities in both technology and human behaviour. Understanding how these digital threats operate is the first step towards building effective defences.

“Bait and Switch”

Phishing attacks remain a significant threat to legal organisations, cleverly executed through deceptive emails or messages that appear to come from trusted sources – clients, colleagues, or reputable suppliers. The goal? To lure recipients into clicking malicious links, downloading harmful software, transferring funds, or divulging sensitive credentials.

For example, just earlier this year, a prominent Sydney-based firm experienced a data breach where hackers gained access to sensitive client information, including case strategies and personal details. The breach was traced back to a phishing email that duped an employee into revealing their login credentials.

“Seize and Extort”

Ransomware attacks are both disruptive and financially damaging. These attacks encrypt critical files, rendering them inaccessible until a ransom is paid. Imagine a court system brought to a standstill because its essential operations are locked behind encrypted files – such scenarios have far-reaching consequences.

In 2021, a U.S.-based law firm suffered such a ransomware attack that encrypted client contracts and active court documents. Beyond the financial burden of the ransom demand, the firm’s reputation was tarnished as clients questioned its ability to protect sensitive information.

“Hack and Hijack “

Data breaches strike at the core of legal institutions’ duty to maintain confidentiality. Cybercriminals infiltrate databases to steal sensitive client information, such as financial data, intellectual property, or strategic business plans. These breaches can lead to severe financial losses, reputational damage, and legal penalties.

A prominent example is the Panama Papers incident, where over 11 million confidential files were leaked from a global law firm. This breach not only exposed private client data but also sparked worldwide debates in politics and finance.

“Eavesdrop and Exploit”

MITM attacks occur when a cybercriminal intercepts communications between two parties, typically a user and an application, or even lawyers and their clients. A cybercriminal can readily get sensitive data by quietly interfering with a trusted system, such as a website or application. The users believe they are only engaging with a trustworthy site and voluntarily provide login credentials, financial information, or other compromising data.

In 2017, Equifax experienced a verified data breach that compromised over 143 million users. As a result, Equifax launched a website named equifaxsecurity2017.com to help consumers determine whether the incident affected them. The problem was that the website was hosted using a shared SSL certificate, which was also used by hundreds of other sites. DNS (via bogus domains) and SSL spoofing were used to redirect users to a fraudulent website or intercept data from it. The man-in-the-middle assaults affected 2.5 million more consumers, bringing the total damage at Equifax to 145.5 million.

“Flood and Disrupt”

DDoS attacks overwhelm servers or networks with excessive traffic, causing systems to crash. For legal institutions, this can disrupt e-filing systems, court portals, and other essential services, leading to operational delays.

In 2019, a European court network faced a DDoS attack that disrupted its case-handling systems for several days, significantly delaying judicial proceedings and creating widespread frustration.

“Trust and Betray”

While external cyber threats often dominate headlines, insider threats – whether intentional or accidental – can be just as damaging. A disgruntled employee might misuse confidential resources, or an uninformed team member might unknowingly expose the system to vulnerabilities. A court clerk installing unauthorised software on a work device could inadvertently introduce malware into the institution’s network. Monitoring staff access and ensuring compliance with security protocols are critical in mitigating these risks.

In May 2023, a German newspaper received more than 23,000 of Tesla’s internal documents – nearly 100 gigabytes of confidential data in total. The documents included employees’ PII, customers’ financial information, Tesla’s production secrets, and customer complaints about Tesla’s electric car features. Investigations revealed that two former Tesla employees misappropriated the information and shared it with the media outlet.

“Break & Breach”

Legal institutions often depend on third-party vendors for services such as cloud storage, transcription, or case management software. Cybercriminals target these vendors to infiltrate the supply chain and, ultimately, the judicial institution.

A notable incident was in 2020 when attackers injected a backdoor into a software update of SolarWinds, a popular networking tool used by many high-profile companies and government agencies. The backdoor allowed attackers remote access to thousands of corporate and government servers. The global-scale attack led to many data breaches and security incidents.

Understanding the nature of common cyber threats targeting legal institutions is the first step in building effective defences. From phishing and ransomware to insider threats and supply chain vulnerabilities, these challenges underscore the urgent need for vigilance and robust cybersecurity measures.

The stakes are high; breaches not only compromise sensitive data but also undermine the trust and efficiency of legal and justice systems. However, the journey does not end with identifying threats. In the next few articles in the series, we will delve deeper into the consequences of these attacks and explore strategies to build resilient defence systems. From advanced technological tools to comprehensive security frameworks, these insights will aim to empower legal institutions to safeguard their operations and uphold the integrity of justice in an increasingly digital world.
