Update — July 16–17, 2026: Abbott Laboratories confirmed unauthorized access to limited Cancer Diagnostics / legacy Exact Sciences systems. See also our Abbott confirmation brief.
Unverified claim — July 15, 2026: Extortion group ShinyHunters listed Abbott-owned Exact Sciences Corporation on its pay-or-leak site, according to Ransomware.live and HookPhish. Actors framed a July 18, 2026 deadline. Exact Sciences had not confirmed a breach at indexing time.
What the listing says
The ShinyHunters post is classic final-warning copy: reach out before the deadline or face a public leak plus "annoying digital problems." Trackers do not show an attested victim count or a field-by-field inventory. Treat any social post inventing "millions of patient records" as marketing until Exact Sciences, Abbott, a regulator, or HIBP publishes numbers.
Why this name matters
Exact Sciences makes at-home cancer screening products including Cologuard. Abbott closed its acquisition of Exact Sciences in March 2026. A leak-site hit on a diagnostics brand is high-signal even when still unverified—patient and employee phishing almost always follows these headlines.
What this is not
This is not a company-confirmed incident in the BreachHistory catalog yet. Consumer attorneys have opened investigations based on the same reports; that is not independent forensic validation.
Who should care
People who used Exact Sciences screening kits, clinic partners who share PHI with Exact labs, and employees/contractors with Exact or Abbott email accounts.
Action items
- Ignore "leak download" DMs claiming Exact Sciences patient files.
- Verify any notice through exactsciences.com or Abbott channels—not reply links.
- Watch Cologuard / results-portal phishing that drops real names.
- Enable MFA on health portals still running password-only login.
