Top 8 Recent High-Profile Company Data Breaches in 2023

1. T-Mobile: May 2023 (and January 2023)

It was announced in May that T-Mobile suffered its second data breach of 2023, after a hack revealed the PINs, full names, and phone numbers of over 800 customers. This is its ninth data breach since 2018 and the second this year already. In early January 2023, T-Mobile discovered that a malicious actor gained access to their systems in November last year and stole personal information, like names, emails, and birthdays, from over 37 million customers. Once they identified the data breach, they were able to track down the source and contain it within a day. T-Mobile claims they may “incur significant expenses” from this data breach, which will be on top of the $350 million they agreed to pay customers in a settlement related to an August 2021 data breach. Not only has T-Mobile lost hundreds of millions of dollars because of their poor security, but they have also lost customers’ trust after multiple breaches of personal information.

2. Yum Brands (KFC, Taco Bell, & Pizza Hut): April 2023

Yum Brands, the parent company of popular fast food chains KFC, Taco Bell, and Pizza Hut, announced in April of 2023 that a cyber-attack that occurred earlier this year in January. They initially believed the attack to only have directly affected corporate data, however they are now being cautious and notifying employees who may have had their personal data breached. In a statement provided to Electric, a representative from Yum! says, “In the course of our forensic review and investigation, we identified some personal information belonging to employees was exposed during the January 2023 cybersecurity incident. We are in the process of sending individual notifications and are offering complimentary monitoring and protection services. We have no indication that customer information was impacted.” The attack resulted in the company closing down almost 300 locations in the UK back in January and has continued to cost the company money by adding security measures, alerting customers, and brand perception. Proving once again, that data breaches are a dangerous financial burden to big companies in 2023.

3. ChatGPT: March 2023

ChatGPT has been in the public discourse for months now because of its revolutionary AI capabilities, but some bad news came in late March when they announced they experienced a data breach. Officials from OpenAI, ChatGPT’s parent company, said “In the hours before we took ChatGPT offline on Monday, it was possible for some users to see another active user’s first and last name, email address, payment address, the last four digits (only) of a credit card number, and credit card expiration date. Full credit card numbers were not exposed at any time” (via CMSWire). The company is handling the aftermath by notifying impacted users, confirming their emails, and adding additional security measures. Many Americans are skeptical of ChatGPT and AI in general, and this data breach is only going to diminish trust more.

4. Chick-fil-A: March 2023

The popular fast-food joint Chick-fil-A confirmed a data breach of their mobile app that exposed customers’ personal information. The company noticed unusual login activity, investigated the anomaly, and determined the cyber-attack happened within the first few months of 2023. The hacker used email addresses and passwords from a third-party to get into the system and acquire info like membership numbers, names, emails, addresses, and more. Although less than 2% of customer data was breached, Chick-fil-A is already taking measures to prevent any future cyber-attacks. The restaurant announced they would increase online security and monitoring, and also reimburse any accounts that suffered from the attack. If you think your account was affected, here is how you can secure your account and get reimbursed for any unauthorized transactions.

5. Activision: February 2023

The video game publisher behind the Call of Duty franchise, Activision, confirmed on February 19th, that they had suffered a data breach back in December. The hacker used an SMS phishing attack on an HR employee to gain access to employee data, including their emails, cell phone numbers, salaries, and work locations. Activision claims that the attack was addressed swiftly and that there was not sufficient data obtained to warrant alerting their employees directly after the data breach. However, a security research group investigated the breach and reported that the hacker had also gained access to the gaming companies 2023 release schedule, along with the sensitive employee info. Due to California law, if 500 or more employees’ data. is breached, the company must alert the team. Time will tell if the hesitation to alert employees of the issue will result in legal, and possibly financial, trouble.

6. Google Fi: February 2023

Google Fi is the most recent high-profile data breach, but it comes as a consequence of the T-Mobile data breach that happened earlier in 2023 (discussed below). Because Google doesn’t have its own network infrastructure and had to piggyback on T-Mobile’s network, they were affected by their massive data breach, compromising their customers’ phone numbers. Although it’s simply phone numbers, there is a lot cybercriminals can do with that kind of customer information, including phishing attacks intended to deceive users into clicking links that allow the hackers access to other info. If you are a Google Fi user, be extra careful of suspicious messages in 2023.

7. MailChimp: January 2023

MailChimp, the email marketing platform, alerted customers that they had suffered a data breach due to a social engineering attack that allowed unauthorized users into an internal customer support tool. The hackers gained access to employee information and credentials, but the company has since identified and suspended those accounts. In response to the data breach, MailChimp has said “Our investigation into the matter is ongoing and includes identifying measures to further protect our platform”, according to Bleeping Computer. This is MailChimp’s first attack of 2023, but they also had data breaches in April and August of 2022. It’s important to know what to do after a data breach to stop hacking attempts before they compromise information multiple times, as MailChimp now knows.

8. Norton Life Lock: January 2023

Norton Life Lock sent a notice to their customers in mid-January that over 6,000 of their customer accounts had been breached in recent weeks due to a “stuffing” attack. Stuffing attacks are when previously compromised passwords are used to hack in to accounts that use a shared password, another reason why multi-factor authentication is so important. Gen Digital, Norton Life Lock’s parent company, sent the notice to accounts they believe could have been compromised and recommended changing passwords and enabling two-factor authentication.

Companies with the Most Data Breaches in 2023

Some of the most high-profile company data breaches are notorious for their frequency as well as the damage caused. Facebook is one of the most popular websites in the world today. However, the company has faced numerous privacy issues over the years. Their most recent attack occurred in 2021, affecting 533 million users. Before that, Facebook was also hacked in 2018 and 2014, leaving 2.2 billion and 50 million people (about twice the population of Texas) impacted, respectively. Yahoo is another infamous victim of back-to-back cybersecurity incidents. The company was hacked in 2013 and 2014, leaving 1 billion and 500 million people affected, respectively. Their most recent attack in 2017 impacted 32 million users. Other companies that have experienced repeat data breaches in the recent past include Amazon, Twitter, Microsoft, Uber, AOL, Dropbox, eBay, and more. But why do these companies experience repeat attacks? Here’s a quick overview of three common reasons:
  • Old vulnerabilities: It’s not uncommon for a hacker to leave a secret window that they can use to access a company’s systems again after a successful first attempt. Failing to patch these vulnerabilities can lead to a second attack.
  • Human error: Employees using weak passwords may expose a company’s systems to subsequent attacks. Other common human errors include employees clicking on malicious links and visiting phishing sites. Unless you perform follow-up security training following an initial breach, employees can repeat previous mistakes that leave your business vulnerable.
  • Malware: Hackers use malicious software such as viruses, ransomware, Trojans, spyware, adware, etc., to steal confidential information from an organization’s network system. If a company fails to step up monitoring protocols after its first breach, there is nothing to stop repeat attacks from occurring.
