Major retailers handle vast amounts of sensitive customer data, from payment card details to personal contact information and online account credentials. Unfortunately, this makes them prime targets for cybercriminals. Over the years, numerous retail giants have suffered significant data breaches, exposing millions of customers to potential identity theft, financial fraud, and privacy violations. These incidents often lead to lawsuits, regulatory fines, and severe damage to customer trust. Examining these past events highlights the ongoing challenge of data security in the retail sector. Here are nine notable examples of major retailers or related companies facing backlash after data breaches compromised customer privacy.

1. Target (2013)
One of the most infamous retail breaches involved Target during the 2013 holiday season. Hackers gained access via credentials stolen from a third-party HVAC vendor. They installed malware on point-of-sale (POS) systems, capturing payment card data (estimated 41 million cards) and personal contact information (for up to 70 million individuals). The breach resulted in massive financial costs for Target, including settlements, security upgrades, and reputational damage. It served as a major wake-up call for the retail industry regarding POS security and third-party vendor risks.
2. The Home Depot (2014)
Shortly after the Target breach, The Home Depot suffered a similar large-scale attack in 2014. Using a vendor’s stolen credentials, cybercriminals deployed custom malware on self-checkout terminals across US and Canadian stores. This malware scraped payment card data (affecting an estimated 56 million cards) over several months before detection. The attackers also stole millions of customer email addresses. Home Depot faced significant costs, including providing identity protection services, settling lawsuits, and implementing enhanced security measures like chip-card readers.
3. TJX Companies (TJ Maxx, Marshalls) (2005-2007)
One of the earliest massive retail data breaches involved TJX Companies, parent of TJ Maxx, Marshalls, and HomeGoods. Disclosed in 2007, hackers exploited vulnerabilities in the company’s wireless network (using weak WEP encryption) over an extended period starting potentially in 2005. They accessed systems storing payment card data, compromising an estimated 45 million (or potentially far more) credit and debit card numbers. The breach highlighted the risks of insecure wireless networks and inadequate data encryption practices in retail environments.
4. Equifax (2017 – Credit Bureau with Retail Impact)
While not a retailer itself, the Equifax data breach had enormous implications for retail and consumer privacy. Hackers exploited a known web application vulnerability to access sensitive personal information (names, Social Security numbers, birth dates, addresses, driver’s license numbers) of roughly 148 million Americans. This type of data is gold for identity thieves, who can use it to fraudulently open retail credit accounts or commit other financial crimes, impacting both consumers and retailers dealing with fraud attempts. It underscored systemic vulnerabilities in data protection.
5. Marriott International (Starwood Guest Database) (Announced 2018)

Marriott disclosed a massive breach in 2018 affecting the guest reservation database of its Starwood division (acquired in 2016), which included brands like Sheraton, Westin, and St. Regis. Unauthorized access occurred over four years prior. The breach exposed personal information (names, addresses, emails, phone numbers, passport numbers, reservation details) of up to 500 million guests, with some encrypted payment card data possibly compromised as well. This breach highlighted risks in integrating systems after mergers and protecting vast hospitality databases.
6. eBay (2014)
The online marketplace giant eBay experienced a major breach in 2014 where attackers compromised employee login credentials. This allowed them access to a database containing customer names, encrypted passwords, email addresses, physical addresses, phone numbers, and dates of birth for approximately 145 million users. While eBay stated financial data was stored separately and not compromised, the stolen personal information could be used for phishing or identity theft. The incident forced a massive password reset for all users, highlighting risks from compromised internal accounts.
7. Neiman Marcus (Multiple Incidents)
Luxury retailer Neiman Marcus has unfortunately experienced multiple data security incidents. One notable breach occurred between 2013 and 2014 involving malware on POS systems capturing payment card data. Another breach, disclosed in 2021 but occurring in 2020, involved unauthorized access to online customer accounts, potentially exposing names, contact info, payment card details (numbers, expiration dates), and gift card numbers for millions of customers. These recurring issues highlight the persistent challenges even high-end retailers face against cyber threats.
8. Under Armour (MyFitnessPal App) (2018)
Under Armour’s popular fitness tracking app, MyFitnessPal, suffered a breach in early 2018. An unauthorized party accessed account data for approximately 150 million users. Compromised information included usernames, email addresses, and hashed passwords (though payment data was stored separately and not affected). While not directly involving retail transactions, the breach impacted a massive user base associated with the retail brand, highlighting security risks for companies managing large datasets via apps connected to their brand ecosystem.
9. Forever 21 (2017 & 2023 Incidents)
Fast-fashion retailer Forever 21 confirmed a breach in 2017 affecting payment card data from POS systems in some stores over several months, partly due to incomplete encryption implementation. More recently, in 2023, the company reported another breach involving unauthorized access to systems containing personal information primarily of current and former employees (over 500,000 individuals). These separate incidents demonstrate ongoing vulnerabilities, whether through POS systems or internal data storage, that retailers must continuously address to protect sensitive information.
The Ongoing Battle for Customer Data Security
These examples underscore the significant and persistent threat of data breaches in the retail sector. Attackers use various methods, from malware on POS systems to exploiting web vulnerabilities or stealing employee credentials. The consequences for consumers include potential financial loss and identity theft, while retailers face enormous costs, lawsuits, and damage to customer trust. Protecting customer privacy requires constant vigilance, robust security investments, employee training, and rapid incident response. As consumers, practicing good password hygiene and monitoring accounts remains a crucial defense against the fallout from these unfortunately common breaches.
