Under Armour Data Breach Lawsuit Alleges Failure to Protect Customer and Employee Data
Under Armour Inc. faces a proposed class action lawsuit tied to a data breach disclosed in November 2025. The lawsuit claims the apparel company failed to protect sensitive personal information belonging to both customers and employees. The filing points to cybersecurity failures and delayed response measures.
The U.S. District Court for the District of Maryland received the complaint. Court records identify Under Armour as the sole defendant. The case centers on alleged lapses in data security safeguards.
What the Lawsuit Alleges
The lawsuit states that unauthorized parties accessed Under Armour’s computer systems. Court filings describe access to internal databases that stored personal information. Plaintiffs claim those systems held customer and employee records at the time of the breach. The complaint lists names as exposed data. The complaint also references contact details. The filing includes email addresses and similar identifying information. No filing confirms exposure of financial account numbers. The lawsuit focuses on personal identifiers.
The complaint asserts that Under Armour controlled how data was collected and stored. Plaintiffs argue the company required users and employees to provide information as a condition of business or employment. The filing states that the duty created a legal obligation to protect that data. Plaintiffs argue that Under Armour failed to implement reasonable cybersecurity safeguards. The complaint points to alleged gaps in network monitoring. The filing claims security controls failed to prevent unauthorized access. The lawsuit describes those failures as inconsistent with industry standards.
The complaint alleges delayed detection of suspicious activity. Plaintiffs argue that earlier detection could have reduced exposure. The filing claims Under Armour lacked adequate alert systems. The lawsuit states that the absence increased the duration of unauthorized access. The complaint also alleges delayed notification to affected individuals.
Plaintiffs state that Under Armour did not promptly inform customers or employees. The filing argues that the delay prevented early protective steps. The lawsuit links that delay to increased risk of identity theft and fraud. Plaintiffs describe the breach as preventable. The complaint argues that stronger safeguards could have reduced the risk. The lawsuit frames the incident as the result of internal security failures rather than an unavoidable external attack.
Customers and Employees Named as Affected Groups
The proposed class includes Under Armour customers who provided personal information through the company’s platforms. The filing also includes current and former Under Armour employees. Court papers state both groups faced exposure through the same compromised systems. Customers appear in the complaint as account holders. Plaintiffs describe data stored through retail platforms, mobile applications, and digital services. The filing references personal identifiers linked to customer profiles. Email addresses and contact details appear as primary examples.
Employees appear in the complaint as data subjects tied to internal records. Plaintiffs describe information connected to employment relationships. The filing references personnel data maintained for business operations. Court documents treat that data as part of the same security environment. Plaintiffs argue that both groups relied on Under Armour to safeguard information. The complaint states that Under Armour exercised exclusive control over storage systems. The filing asserts that control imposed identical duties on customers and employees.
The lawsuit applies a unified data security theory. Plaintiffs argue that cybersecurity failures affected all stored records. The complaint does not separate safeguards by user type. The filing instead frames the breach as system-wide. No allegation confirms misuse of exposed information. Court filings do not cite identity theft incidents. Plaintiffs focus on the increased risk of future harm. Monitoring costs appear as a claimed burden.
Plaintiffs seek relief for time spent on protection efforts. The complaint references credit monitoring and identity protection measures. The lawsuit frames those costs as foreseeable consequences of the breach.
Timeline of the Alleged Breach
Under Armour disclosed the data breach in November 2025. The company issued a public notice that acknowledged unauthorized access. Public statements confirmed exposure tied to internal systems. The lawsuit states the breach occurred before that disclosure. Court filings argue unauthorized access continued for a period of time. Plaintiffs claim the company did not identify the intrusion immediately.
Court filings do not list a precise intrusion date. The complaint emphasizes delayed detection rather than a single event. Plaintiffs argue that security controls failed to flag suspicious activity at an early stage. The filing alleges internal monitoring gaps. Plaintiffs argue that those gaps allowed unauthorized access to persist. The complaint states that earlier alerts could have limited the scope of exposure.
The lawsuit also focuses on notification timing. Plaintiffs argue affected individuals did not receive prompt notice. Court papers state delayed notice reduced the ability to take early protective steps. Under Armour’s public breach notice plays a central role in the case. Plaintiffs cite that notice as confirmation of unauthorized access. The filing treats the disclosure as an acknowledgment of a security failure rather than a precautionary statement.
The complaint frames the timeline as critical to liability. Plaintiffs argue that delayed detection and delayed notice compounded the risk. Court filings describe those delays as avoidable under reasonable cybersecurity practices.
Legal Claims Raised in the Complaint
The lawsuit raises negligence claims against Under Armour. Plaintiffs allege the company failed to implement reasonable cybersecurity measures. Court filings argue that those failures exposed stored personal information to unauthorized access. The complaint describes a duty to protect personal data. Plaintiffs state that Under Armour collected and retained information as part of normal business operations. The filing argues that the duty requires safeguards consistent with modern security standards.
Negligence allegations focus on prevention and response. Plaintiffs argue that Under Armour failed to maintain adequate system monitoring. The complaint also alleges failure to promptly detect and contain unauthorized access. Court papers frame those failures as breaches of ordinary care. The lawsuit also raises unjust enrichment claims. Plaintiffs argue that Under Armour benefited financially from collecting personal information. The complaint states the company avoided adequate security investment while retaining those benefits. Court filings argue that the imbalance supports restitution.
State consumer protection claims appear in the filing. Plaintiffs allege deceptive or unfair practices tied to data security representations. The complaint argues that Under Armour implied data protection that did not exist in practice. Court papers treat those claims as separate legal violations. The complaint seeks injunctive relief. Plaintiffs request court-ordered improvements to cybersecurity systems. The filing references updated safeguards and monitoring controls as requested remedies.
Monetary relief also appears in the lawsuit. Plaintiffs seek damages tied to the increased risk of identity theft. Court papers include requests for reimbursement of monitoring expenses. Attorneys’ fees and costs also appear in the requested relief. The lawsuit frames those claims as corrective. Plaintiffs argue court oversight remains necessary. Court filings present the case as an effort to force long-term security reform rather than punishment alone.
