On October 13, 2026, a class action lawsuit was filed against Dexcom Inc. in California, alleging that weak data security allowed hackers to steal personal and medical information of customers and employees. The cybercriminal group ShinyHunters claimed responsibility for the breach, threatening to publish the stolen data unless contacted by Dexcom. The lawsuit cites various security failures, including inadequate employee training and violations of HIPAA regulations. Dexcom disclosed on October 10 that unauthorized access occurred due to voice phishing, but it has not confirmed if this incident is linked to ShinyHunters. The stolen data reportedly includes names, birthdates, driver's license numbers, financial information, and medical records. The lawsuit claims Dexcom failed to notify affected individuals promptly, causing them distress and anxiety.
