What happened in the Dexcom data breach
According to the notice letter Dexcom ("Dexcom") filed with the California Attorney General, on November 2, 2026, Dexcom determined that some individuals' information may have been involved in an incident involving unauthorized access to certain employee accounts. The letter states that Dexcom engaged outside counsel and a cybersecurity firm to investigate, and that the investigation determined an unauthorized third party gained access through social engineering and was able to download certain files. Dexcom says it took steps to contain the incident, including revoking the compromised accounts' access, and that the investigation found no ongoing evidence of any unauthorized activity.
The letter states that, following the investigation, Dexcom reviewed the affected files. It says the information that may have been involved includes one or more of the following: name, Social Security number, date of birth, and government identification information. The California Attorney General lists the notice with a reported date of November 13, 2026. The date on the posted letter is a placeholder, and the filing does not state how many people were affected. Dexcom is offering a complimentary two-year membership through Kroll that includes single bureau credit monitoring, fraud consultation, and identity theft restoration.
Whether Dexcom's security practices met legal standards, and how the incident affected the people who received notices, are among the issues being evaluated.
