biggest data breaches of 2024

This year has been a wake-up call for cybersecurity, with significant data breaches shaking companies across various sectors and costing them millions. From healthcare to ticketing services, no industry is safe from cyber threats. For small and midsize businesses (SMBs), these breaches highlight vulnerabilities that could lead to dire consequences if left unaddressed. Let’s explore the five most impactful breaches of 2024 and outline steps your business can take to enhance its security.

National Public Data

Earlier this year, a hacking group announced it had stolen an astonishing 2.7 billion personal records from a well-known background checking and public data site. This breach included sensitive information such as Social Security numbers and addresses. While some data has surfaced on the dark web, experts are still verifying its authenticity. Regardless, the potential compromise of countless Social Security numbers means individuals should act quickly to protect themselves. Key steps include freezing credit to prevent identity theft and monitoring financial accounts closely. Find out if you were exposed here!

  1. Ticketmaster
    1. A major breach at Ticketmaster exposed personal and financial details of over 560 million customers, including names, emails, phone numbers, and payment information. The hackers gained access during a two-month window, raising serious questions about Ticketmaster's security protocols. Many customers reported unauthorized transactions and identity theft in the aftermath. This incident further complicates Ticketmaster’s legal challenges, as it is already under scrutiny from the US Department of Justice.
  2. Change Healthcare
    1. In February, Change Healthcare suffered a massive ransomware attack that compromised the personal data of more than 145 million individuals. This incident marked one of the largest healthcare breaches in history, revealing sensitive data such as names, Social Security numbers, and medical records. The fallout prompted a reevaluation of cybersecurity practices across the healthcare sector, as many organizations recognize the urgent need to bolster defenses against similar attacks.
  3. AT&T
    1. In March, AT&T reported a breach that exposed the personal information of approximately 73 million customers. This incident involved sensitive data, including Social Security numbers and account passcodes, with links to data breaches from as far back as 2019. Following the breach, AT&T initiated an investigation while facing potential class action lawsuits. This incident underscores the importance of robust cybersecurity measures, even for large corporations.
  4. Dell
    1. In May, Dell experienced a security breach through a brute-force attack on a reseller’s client portal, compromising 49 million records. This data included customer names, email addresses, and payment information. Dell’s response included a public apology and commitments to enhance security measures, but the breach raised questions about their overall cybersecurity practices and exposed them to regulatory scrutiny.

 

What These Breaches Mean for You

If you’ve been affected by any of these breaches, immediate action is crucial. Freezing your credit and checking bank accounts regularly can help mitigate potential damage. Utilize resources like www.haveIbeenpwnd.com to determine if your email has been compromised.

 

Implications for Your Business

While these incidents primarily impacted large organizations, SMBs are not exempt from cyber threats. In fact, they are increasingly targeted due to often weaker security defenses. A single breach could cost a small business significantly in terms of downtime, lost data, and reputational harm.
