Abbott's cancer diagnostics business includes Exact Sciences, which the company acquired earlier this year in a$21 billion deal to acquire Exact Sciences. According to the statement, Exact Sciences' legacy systems are independent of Abbott's systems.

Abbott said: "This does not affect any business operations, products, or product supply, manufacturing, or laboratory operations, nor our ability to serve patients." Currently, the company does not expect the incident to have a material impact on its business or financial results.

After discovering the attack, Abbott has contacted third-party cybersecurity experts and law enforcement, and is currently investigating the information that was accessed.

Abbott did not disclose the type of information accessed. The company declined to further respond to MedTech Dive's request for comment regarding when the attack was discovered and the type of information accessed.
