Healthcare giant Abbott acquired Exact Sciences Corporation in March of 2026. Formerly Exact Sciences Corporation, now Abbott, specializes in cancer screening and diagnostic tests. It is the company behind Cologuard and Cancerguard. It recently experienced a data security incident, potentially impacting sensitive information belonging to an undisclosed number of Abbott customers.
According to an article published by technology news outlet Bleeping Computer, a hacking and extortion group listed “Exact Sciences Corporation” as a victim on its data leak website. Bleeping Computer says the group, called ShinyHunters, claims to have stolen over “30 million rows of customer personally identifiable information (PII) from multiple datasets containing names, email addresses, phone numbers, physical addresses, dates of birth, and more than one million Social Security numbers. The group also claimed to have stolen over 22 million client notes containing doctor-patient conversations, more than 20 million medical orders, and customer agreements and NDAs.” However, Bleeping Computer was unable to independently verify these claims. Abbott released a statement on July 16, 2026, confirming its Cancer Diagnostics business experienced a data breach. The company emphasizes that a limited number of its internal systems were impacted, and no other Abbott businesses, sites, or systems were breached.
