Abbott Laboratories, one of the world’s largest healthcare and medical device companies, is investigating two apparently unrelated cyber incidents after confirming unauthorized access to internal systems. While Abbott says there has been no impact on manufacturing, laboratory operations, or patient care, cybercriminal groups ShinyHunters and ShadowByt3$ claim the breaches were far more extensive. Those claims remain unverified at the time of writing and, so far, unsupported by publicly leaked data.

The incidents reportedly involve Abbott’s Cancer Diagnostics business and its LabCentral customer portal for core laboratory diagnostics.

Several news outlets point to an official statement by Abbott, which has since been removed:

“Unauthorized access was limited to internal systems of the Cancer Diagnostics business only, with no impact to other Abbott businesses, sites, systems, product availability, manufacturing, or lab operations.”

Regarding LabCentral, Abbott told reporters that it is an externally hosted portal and that there has been “no known exposure of sensitive customer or business information.”
