Year of Cybersecurity Failures: The Biggest Data Breaches and Missteps of the Year

Every year, a new crop of companies falls victim to catastrophic data breaches, leaving millions of people exposed to risks of identity theft and fraud. Despite growing awareness and lessons from past incidents, this year brought a troubling repeat of poorly handled cybersecurity failures. From healthcare giants to retail chains, here’s a look at some of the most notable breaches that shaped 2023.

23andMe: Shifting Blame Amid a Genetic Data Disaster

In one of the most high-profile breaches of the year, genetic testing company 23andMe suffered a massive hack that exposed the genetic and ancestry data of nearly 7 million users. Hackers exploited weak security measures, gaining access to thousands of accounts and scraping sensitive data.

Instead of taking accountability, 23andMe initially blamed users for not adequately securing their accounts. Legal representatives of affected customers denounced this stance as “absurd,” and regulatory bodies in the U.K. and Canada launched investigations into the breach. While the company eventually implemented multi-factor authentication, critics argue it was too little, too late. Adding to its woes, 23andMe later laid off 40% of its workforce, leaving questions about the security of its vast database of genetic information.

Change Healthcare: A Prolonged Healthcare Crisis

Change Healthcare, a key player in the U.S. healthcare system, found itself at the center of chaos following a February cyberattack. The breach disrupted its entire network, affecting billing and insurance services for millions of Americans. Patients faced delays in receiving medications, and hospitals struggled to gain approval for critical procedures.

The hack, stemming from a compromised user account without multi-factor authentication, led to a $22 million ransom payment. Despite this, stolen data remained in the hands of cybercriminals, forcing the company to pay additional ransoms. It wasn’t until October — seven months later — that Change Healthcare revealed the full extent of the breach: over 100 million individuals’ private health data had been compromised.

Synnovis: Months of Disruption in the U.K.

The U.K.’s National Health Service (NHS) faced months of turmoil after a ransomware attack on Synnovis, a London-based pathology services provider. The June attack disrupted blood tests, led to the cancellation of thousands of outpatient appointments, and delayed over 1,700 surgeries.

The Qilin ransomware group claimed responsibility, leaking 400GB of sensitive data, including patient names, health records, and blood test details. Experts criticized Synnovis for failing to adopt two-factor authentication, which could have prevented the breach. The incident also took a toll on staff, with unionized workers staging strikes over increased workloads and insufficient support during the crisis.

Snowflake: A Cloud Computing Giant Under Fire

Cloud computing company Snowflake became embroiled in a series of mass data breaches involving high-profile clients like AT&T and Ticketmaster. Hackers exploited malware-infected employee devices and Snowflake’s lack of enforced multi-factor authentication to infiltrate and steal vast amounts of data.

Snowflake’s response was muted, though it eventually made multi-factor authentication mandatory for all customers. The breach underscored the risks companies face when relying on single-factor security, highlighting the importance of robust authentication protocols.

Columbus, Ohio: Silencing the Messenger

In an unusual twist, the city of Columbus, Ohio, faced criticism not just for a ransomware attack but for its response to a whistleblower. After a cyberattack exposed sensitive data for over 500,000 residents, including Social Security numbers and domestic violence records, the city assured the public that the stolen data was unusable.

A security researcher, however, found evidence to the contrary and alerted journalists. Rather than addressing the breach, the city sued the researcher to prevent further disclosures. Facing public backlash, Columbus eventually dropped the lawsuit, but the incident raised questions about transparency and accountability in the wake of cyberattacks.

Salt Typhoon: Exploiting Legacy Laws

A 30-year-old U.S. law designed to aid law enforcement became a vulnerability exploited by Salt Typhoon, a China-backed hacking group. The attackers gained access to wiretap systems mandated by the 1994 CALEA law, targeting major phone and internet providers.

Among their victims were senior U.S. officials and presidential candidates, whose real-time communications and metadata were compromised. In response, federal authorities urged the public to adopt end-to-end encrypted messaging apps to safeguard their privacy.

MoneyGram: A Silent Breach with Major Fallout

MoneyGram, a leading money transfer company, confirmed a cybersecurity incident in September but provided few details. Weeks later, it was revealed that hackers had stolen sensitive customer information, including Social Security numbers, transaction histories, and government IDs. Despite these revelations, MoneyGram has yet to disclose the total number of affected customers, drawing criticism for its lack of transparency.

Hot Topic: Ignoring a Massive Retail Breach

Retail giant Hot Topic made headlines after a data breach exposed the personal information of 57 million customers. Stolen data included email addresses, phone numbers, and partial credit card details. Despite the scale of the incident, the company has not publicly acknowledged the breach or notified affected individuals.

Have I Been Pwned, a breach notification platform, stepped in to alert users, emphasizing the importance of proactive communication in the aftermath of cyberattacks.

Key Takeaways for the Future

This year’s string of cybersecurity failures highlights recurring themes: inadequate security measures, poor incident response, and a lack of transparency. Companies must prioritize robust protections like multi-factor authentication and adopt clear communication strategies during crises. As cyber threats continue to evolve, proactive security and accountability will remain critical to safeguarding sensitive data and maintaining public trust.
