On October 10, 2026, ransomware intelligence trackers reported that the group "Redact" had listed DexCom — the Nasdaq-listed continuous glucose monitoring maker with roughly 4.97 billion dollars in revenue and about 11,100 employees — on its dark-web leak site, alleging it exfiltrated 3.3 terabytes of company data. Treat that claim carefully: this is an attacker-side allegation only. DexCom has not publicly confirmed any incident, no regulatory filing has surfaced, and no independent forensic evidence has corroborated the listing.

A ransomware group calling itself Chaos announced on October 9, 2026 that it had exfiltrated 1,500 gigabytes of data from Astrana Health, Inc., a California-based physician-management company whose network supports roughly 20,000 affiliated medical providers. The group claims the theft followed Astrana's decision not to negotiate with the attackers, and says the stolen trove includes patient diagnoses and personal information.
