Data Breaches That Have Happened in 2022 and 2023 So Far

Apple, Meta, and Twitter have all disclosed cybersecurity attacks over the past 12 months. We track the latest data breaches.

Data breaches have been on the rise for a number of years, and sadly, this trend isn't slowing down. The last year or so has been littered with thefts of sensitive information. Data breaches have affected companies and organizations of all shapes, sizes, and sectors, and they're costing US businesses millions in damages.

The widely-covered T-mobile data breach that occurred last year, for instance, cost the company $350 million in 2022 – and that's just in customer pay outs. This puts more onus than ever on businesses to secure their networks, ensure staff have strong passwords, and train employees to spot the telltale signs of phishing campaigns.

Below, we’ve compiled a list of significant, recent data breaches (and a couple of important data leaks) that have taken place since January 1, 2022, dated to the day they were first reported in the media.

December 11

Norton Healthcare Data Breach: Norton Healthcare has suffered a data breach impacting an estimated 2.5 million people. The firm, based in Kentucky, says that threat actors gained unauthorized access to personal information about millions of patients, as well as a considerable number of employees.

Although the data breach happened between May 7 and May 9, it only came to light this month when it was filed with Maine's attorney general. An internal investigation by Norton suggests the threat actors had access to a broad selection of sensitive information.

Data Breaches vs Data Leaks vs Cyberattacks

This article largely concerns data breaches. A data breach occurs when a threat actor breaks into (or breaches) a company, organization, or entity’s system and purposefully lifts sensitive, private, and/or personally identifiable data from that system. When this happened, companies are sometimes forced to pay ransoms, or their information is stolen ad posted online. According to one estimate, 5.9 billion accounts were targeted in data breaches last year.

This is different from a data leak, which is when sensitive data is unknowingly exposed to the public/members of the public, such as the Texas Department for Insurance leak mentioned above. The term “data leak” is often used to describe data that could, in theory, have been accessed by people it shouldn't of, or data that fell into the hands of people via non-malicious means. A government employee accidentally sending someone an email with sensitive data is usually described as a leak, rather than a breach.

Although all data breaches fall under the umbrella of a “cyberattack“, cyberattacks are not limited to data breaches. Some cyber attacks have different motivations – such as slowing a website or service down or causing some other sort of other disruption. Not all cyberattacks lead to the exfiltration of data, but many do.

How Can I Protect My Organization From Cyber-Attacks?

Ensuring you take steps to protect your company from the sorts of cyber attacks that lead to financially fatal data breaches is one of the most crucial things you can do. It's not just businesses that are at risk, however – schools and colleges are some of the most frequently targeted organizations that suffer huge financial losses.

Some companies and organizations – like Lincoln College – have had to shut down due to the fallout costs of a cyberattack. There has never been more of an onus on companies, colleges, and other types of organizations to protect themselves.

Unauthorized access to networks is often facilitated by weak business account credentials. So, whilst passwords are still in use, the best thing you can do is get your hands on a password manager for yourself and the rest of your staff team. This will allow you to create robust passwords that are sufficiently long and different for every account you hold. However, you'll also need to use additional security measures, like 2-Factor Authentication, wherever possible, to create a second line of defense.

Another thing you must do is ensure your staff has sufficient training to spot suspicious emails and phishing scams. Around 70% of cyberattacks target business email accounts, so having staff that can recognize danger when it's present is just as important as any software.
