Top Breaches of 2023 and How You Can Protect Yourself

Computer Security

The battle against cyber threats is an ongoing challenge and unfortunately there is no one thing that will protect you 100% and 2023 has proven to be a watershed year for data breaches. Data compromises have surged to an all-time high in the U.S. This is based on data from the first 9 months of the year. Meaning that numbers will only end up higher for the year.

The last data breach record was set in 2021. That year, 1,862 organisations reported data compromises. Through September of 2023, that number was already over 2,100. In Q4 of 2023, some companies and organisations that experienced data compromises in Australia were:

  • Woollahra Council Library
  • Yakult Australia
  • St Vincent’s Health Network
  • Melbourne Arts Centre
  • University of Wollongong
  • DP World
  • Queensland Rural Fire Service

This data underscores the relentless efforts of cybercriminals to exploit vulnerabilities, as well as access sensitive information. The above list shows some of the larger companies and organisations (with dedicated IT security staff) that had gotten hit but doesn’t list the thousands of smaller business that were affected but may not have been reported.

Let’s take a look at the main drivers of this increase and the urgent need for enhanced cybersecurity measures for organisations both big and small.

1. The Size of the Surge

The above numbers are staggering with data breaches in 2023 having reached unprecedented levels compared to previous years. The scale and frequency of these incidents is very concerning. They emphasise the evolving sophistication of cyber threats. As well as the challenges both big and small organisations face in safeguarding their digital assets.

2. Healthcare Sector Under Siege

One of the most disturbing trends is the escalating number of breaches in healthcare. Healthcare organisations store highly sensitive patient information and as a result, they have become prime targets for cybercriminals. The breaches jeopardise patient privacy and also pose serious risks to the integrity of medical records. This creates a ripple effect that can have long-lasting consequences.

3. Ransomware Reigns Supreme

Ransomware attacks continue to dominate the cybersecurity landscape. Cybercriminals are not merely after data but also monetary returns and they are wielding the threat of encrypting valuable information and then demanding ransom payments.

The sophistication of ransomware attacks has increased with threat actors employing advanced tactics to break into networks and encrypt their data. They are also using many different methods to extort organisations for financial gain.

4. Supply Chain Vulnerabilities Exposed

In todays modern world, business ecosystems have an interconnected nature witch has made supply chains a focal point for cyberattacks. The compromise of a single entity within this chain can have cascading effects throughout the organisations in the chain. Cybercriminals are exploiting these links and are using less defended networks to attack other interconnected businesses.

5. Emergence of Insider Threats

External threats remain a significant concern, but the rise of threats from the inside is adding a layer of complexity. Whether through malicious intent or unwitting negligence, insiders contribute significantly to data breaches. Organisations are now grappling with a challenge and they need to distinguish between legitimate user activities and potential insider threats.

6. IoT Devices as Entry Points

The proliferation of Internet of Things (IoT) devices (a lot of which have little or no security) has expanded the attack surface and subsequently there has been an rise in data breaches originating from compromised IoT devices. These connected endpoints range from smart home devices to industrial sensors and the rise in compromises are directly related to the fact that they are often inadequately secured. This provides cyber criminals with entry points to exploit vulnerabilities within networks.

7. Critical Infrastructure in the Crosshairs

Critical infrastructure is a high value target for cyber attackers. These networks  include energy grids, communication infrastructure, water supplies and transportation systems. The potential consequences of a successful breach in these sectors are often financial, but can be extended to public safety and national security. As cyber threats evolve, safeguarding critical infrastructure has become an urgent imperative for governments and large organisations.

8. The Role of Nation-State Actors

Geopolitical tensions have spilled into the digital realm with nation-state actors, driven by political and economical motives, increasingly playing a role in sophisticated cyber campaigns. They often use previously unknown (zero day) techniques to compromise sensitive data and disrupt operations to advance their own strategic interests in the global cyber landscape.

9. The Need for a Paradigm Shift in Cybersecurity

The surge in data breaches underscores the need to rethink cybersecurity strategies. It is no longer a question of if an organisation will be targeted but when. Also, no business is safe, with business both very large and very small (and everyone in between) are in the crosshairs of all the unscrupulous hackers out there.

Proactive measures include:

  • A culture of cyber awareness amongst staff.
  • Robust cybersecurity frameworks.
  • Continuous monitoring.

These are essential for mitigating the risks posed by evolving cyber threats.

10. Collaboration and Information Sharing

We will never be 100% safe and secure but collaboration among organisations and information sharing within the cybersecurity community are critical to help slow down and alleviate as much as we can. Especially as cyber threats become more sophisticated. Threat intelligence sharing enables a collective defence against common adversaries and allows organisations to proactively fortify their defences. They do this based on insights gained from the broader cybersecurity community.
