2024 has seen several significant data breaches across different sectors, affecting millions of users globally. These incidents underscore the growing cyber-security challenges faced by companies and the importance of strong data protection measures. Let’s take a closer look at some of the most notable breaches of the year involving AT&T, Star Health, WazirX, and Change Healthcare.
1. AT&T: Telecommunications Giant Under Attack
AT&T, a leading telecommunications provider, experienced two major breaches in 2024. The first, which occurred in July, resulted in the exposure of customer phone numbers and call records. This breach was caused by a vulnerability through an external account with Snowflake, a data cloud company, rather than through AT&T’s internal systems. The attack affected nearly all of AT&T’s customers, highlighting the interconnected risks posed by third-party systems. Earlier in March, another breach involving 73 million customer records was leaked, making it a challenging year for the telecom company. These incidents stress the importance of ensuring security not only in internal systems but also in external partnerships.
2. Star Health: A Critical Hit to Healthcare Data
Star Health, one of India’s largest health insurance companies, also suffered a significant data breach this year. Sensitive medical data of millions of policyholders was compromised, potentially leading to identity theft and misuse of personal health information. Healthcare organizations are particularly vulnerable to such attacks due to the highly sensitive nature of the data they handle, and the breach at Star Health demonstrates the urgent need for enhanced cybersecurity protocols in this sector.
3. WazirX: Cryptocurrency Exchange Faces New Threats
The growing popularity of cryptocurrency has made exchanges like WazirX attractive targets for hackers. WazirX, one of India’s largest crypto exchanges, was hit by a breach in 2024 that exposed user data and raised concerns about the security of digital currencies. The breach highlights the need for stronger security measures within the cryptocurrency industry to prevent unauthorized access to financial assets and personal data.
4. Change Healthcare: Disrupting Healthcare Services
Change Healthcare, a U.S.-based health insurance company, faced a massive cyberattack that affected a large portion of its user base. The breach resulted in the exposure of sensitive medical records, causing significant disruptions to healthcare services across the country. Hospitals and healthcare providers relying on Change Healthcare’s platforms experienced service outages, making this one of the most disruptive attacks on the healthcare sector in 2024.
Lessons from 2024’s Major Data Breaches
The data breaches of 2024 serve as a reminder that no industry is immune to cyberattacks. Whether in telecommunications, healthcare, or cryptocurrency, businesses must prioritize cybersecurity and take proactive steps to safeguard sensitive information. As cyber threats continue to evolve, organizations should invest in robust security measures, regular system updates, and comprehensive incident response plans.
