Under Armour cyberattack may put over 7 million at risk - but it's staying quiet

• Everest ransomware group leaked 72.2m Under Armour accounts after failed negotiations
• Data includes names, emails, birthdates, purchase history, and possibly loyalty program details
• Under Armour remains silent; class action lawsuit filed on behalf of affected customers

Online chatter have claimed Under Armour suffered a major ransomware attack and a data breach, but so far, the sports apparel giant is staying tight-lipped.

Have I Been Pwned? (HIBP), a free online service that lets people check whether their email address or phone number appeared in known data breaches, said it added 72.2 million accounts stolen in a recent Under Armour breach.

Under Armour has not denied, nor confirmed, the breach, staying quiet - its dedicated newsroom site, as well as socials, do not mention the incident.
