**BREAKING: 72 Million Under Armour Customer Records Surface Online in Massive Data Breach**

In a disturbing turn of events, American sportswear giant Under Armour has confirmed that it is investigating a massive data breach after a staggering 72 million customer records were posted online by a cybercriminal. The incident, which occurred in November last year, was initially claimed by the Everest ransomware gang, who allegedly attempted to extort a ransom from the company.

According to Have I Been Pwned, an organization that tracks and notifies affected individuals of data breaches, the stolen data includes sensitive information such as names, dates of birth, genders, geographic locations, and purchase records. The cybercriminal, who posted the data on a popular hacking forum in January, shared a sample with TechCrunch, which revealed millions of Under Armour customer purchase records and employee email addresses.

"In November 2025, the Everest ransomware group claimed responsibility for a massive cyberattack on Under Armour, exfiltrating ~343 GB of sensitive data," Have I Been Pwned reported. "After Under Armour reportedly failed to pay the ransom within the 7-day deadline, the stolen data was published publicly online."

The compromised data includes customers' dates of birth, email addresses, genders, geographic locations, names, and purchases. While Under Armour has confirmed that payment systems and passwords were not affected, it is believed that only a small percentage of customers may have had sensitive information exposed.

In response to the breach, Under Armour has stated that it is investigating claims with the help of external cybersecurity experts. The company denies that tens of millions of sensitive records were compromised, but has acknowledged that a data breach did occur.

This incident serves as a stark reminder of the growing threat of cybercrime and the importance of robust security measures in protecting customer data. As this story continues to unfold, Under Armour customers are advised to remain vigilant and monitor their accounts for any suspicious activity.
