Tenga Data Breach

On February 13, 2026, Tenga discovered that an unauthorized party had gained access to the professional email account of one of its employees. The intrusion occurred between 12:00 a.m. and 1:00 a.m. PT, during which the unauthorized actor used the compromised account to send unsolicited spam emails to contacts found in the account history.

Following the incident, Tenga took immediate steps to secure the compromised account and launched an internal investigation.

Tenga is a global consumer product company that maintains customer communication records for order support and customer service inquiries.

After the incident was confirmed, Tenga enacted enhanced security protocols and initiated forensic review processes to verify that no other company systems had been compromised.

Tenga notified law enforcement of the unauthorized access and issued data breach notifications to affected individuals whose information may have been viewed or acquired within the compromised inbox.

If you received a Data Breach Notification Letter from Tenga, it confirms that your information may have been impacted.

What information is involved in the Tenga Data Breach?

Compromised information may include:

Tenga confirmed that no Social Security numbers, credit card numbers, debit card numbers, or billing information were involved in this incident. However, exposed email content can still pose risks, including phishing attempts, impersonation schemes, and unauthorized account access attempts.

Your Personally Identifiable Information (PII) includes details that can be used to identify you. Organizations are legally required to protect this information, and when compromised, consumers may face risks of identity theft and fraud.

A specific category of PII is Protected Health Information (PHI), which pertains to personal medical data. PHI is safeguarded under both federal and state regulations. Entities such as healthcare providers and businesses that manage PHI must ensure its security. Just like PII, compromised PHI can be misused by identity thieves, and it’s common for cybercriminals to use both types of information together.

To protect affected individuals, Tenga recommends deleting any suspicious messages sent from hayato@tenga.co.jp between February 12 and February 13, 2026, updating passwords—particularly if the same credentials are used across multiple services—and monitoring personal accounts for unusual or unauthorized activity.

Residents of California benefit from additional privacy protections under the California Consumer Privacy Act (CCPA), which grants enhanced rights regarding personal data. Additionally, California residents also benefit from medical privacy protections under the Confidentiality of Medical Information Act (CMIA), which specifically grants enhanced protections for confidential medical data.

If you received a NOTICE OF DATA BREACH letter from Tenga, your personal information and email communications may be at risk. Information exposed in email accounts can be exploited by cybercriminals for phishing, fraud, or other forms of digital exploitation.
