Protecting your personal information online is important, and news of data breaches can be worrisome when your data may have been compromised. Sometimes hackers force a data breach, which can happen through malware, a ransomware attack, or other types of cyberattacks. Other times, data may be leaked through a vulnerability in the code of a website or app and end up in the hands of cybercriminals. 

Regardless, protecting your personal information is important for you and critical to the companies that have your data — even small businesses.

One of the latest data breaches involves more than 70,000 people whose information was held by Lending Tree, LLC. The breach was caused by issues with the coding of its website that led to hackers gaining unauthorized access. As part of this breach, individuals' names, Social Security numbers, addresses, and dates of birth were compromised. Lending Tree alerted individuals whose information may have been compromised.

Companies have a duty to inform you if your sensitive data has been part of a data leak. However, in many cases, the companies send out those notifications after doing a lengthy investigation, which means your information could be exposed for a while before you know. 

It is important that you also protect your data by using strong passwords and checking your credit reports for suspicious activity.

We suggest staying informed on recent data breaches in case any of these organizations have your data. The sooner you know your information is at risk, the sooner you can protect yourself, your accounts, and your identity.

7. May 2022: Texas Department of Insurance

A web application used to manage worker’s compensation information was the culprit for a recent data breach of the Texas Department of Insurance. The breach took place on Jan. 4, 2022, due to a programming issue that allowed access to protected information.

8. April 2022: Block and Cash App

However, the forensic report concluded that the hackers did not gain access to any Okta accounts or make any configuration changes.

The Lapsus$ hacking group has been the instigator behind dozens of recent cybercrimes. Run by teens, Lapsus$ successfully hacked well-known companies through ransomware and social engineering attacks, including Microsoft, Nvidia, Samsung, T-Mobile, Okta, and EA Games.

12. March 2022: Comstar

Comstar, an ambulance billing service, notified customers about a security breach on March 26. The Comstar network was accessed by unauthorized users and Comstar launched an investigation.

More than 4,000 organ donors and recipients had their data leaked for more than 16 years as part of a data breach on Virginia Commonwealth University Health System.

19. January 2022: Twitter

In January, a hacker alerted Twitter to security flaws on the popular social media website. The hacker said Twitter was vulnerable to hackers seeking to use information maliciously. Twitter said it fixed the problem, but shortly after, a different hacker began selling more than 5 million Twitter users' information on the dark web. The hacker was seeking at least $30,000 for the data. The information in the hack included phone numbers and email addresses.
