Abbott Discloses Cyberattack on Cancer Diagnostics Business
Abbott Laboratories confirmed a cyberattack targeting its cancer diagnostics business, which includes systems from Exact Sciences a company it acquired in a $21 billion deal earlier this year. The incident involved unauthorized access to a limited number of internal systems, though Abbott stated that the attack did not disrupt business operations, product availability, manufacturing, or patient services. The company also noted that no other Abbott businesses, sites, or systems were affected and that it does not expect a material financial impact.
Details on the type of information accessed or the timeline of the attack remain undisclosed. Upon discovery, Abbott engaged third-party cybersecurity experts and notified law enforcement, with an ongoing investigation into the breach. The legacy systems of Exact Sciences were reported to be separate from Abbott’s infrastructure.
This incident follows a recent surge in cyberattacks targeting medtech companies, including a March breach at Stryker and a separate attack on Medtronic. The manufacturing sector, particularly healthcare-related industries, has seen increased targeting due to vulnerabilities in IT/OT convergence, prompting leaders to bolster cybersecurity defenses. Abbott’s disclosure underscores the growing cyber risks facing critical industries amid evolving threat landscapes.
