What Happened
Dexcom’s 2026 incident appears to have been a third-party disclosure error, not a direct hack: on April 29, 2026, Lockton reportedly sent an Excel file to three vendors for a Dexcom employee family-forming benefits RFP, and the file accidentally included employee personal information that was not meant to be shared. The exposed data may have included names, Social Security numbers, dates of birth, and limited benefits election information, but the available source does not provide a confirmed record count.
