ABBOTT Laboratories is investigating two separate cyber incidents involving its Cancer Diagnostics business and the externally hosted LabCentral portal, denying any operational disruptions or data exposure. The hacker groups ShinyHunters and ShadowByt3$ claim to have stolen significant amounts of sensitive data, including millions of patient records and PII, while Abbott asserts no evidence of such exposure has been found.
Abbott has acknowledged unauthorized access and activated incident response, yet the attackers have threatened to release the stolen data unless contacted by July 21, 2026. Meanwhile, Abbott customers are advised to follow various security measures to protect their information.
