Abbott confirms a Cancer Diagnostics cyber incident; ShinyHunters claims a vished Entra SSO account and 30M+ records
Abbott Laboratories is investigating a cyber incident and states there was "unauthorized access to a limited number of internal systems in our Cancer Diagnostics business only," adding that there is "no impact to any other Abbott businesses, sites or systems" and that the legacy Exact Sciences systems (Exact Sciences was folded into Abbott's diagnostics business in a 2026 acquisition) remain separate from Abbott's core infrastructure (Abbott, 2026-07-16). Abbott has not named an actor, confirmed a method, or disclosed what kind of information was accessed (MedTech Dive, 2026-07-17).
The ShinyHunters extortion group (registry-tracked, alias UNC6240) claims responsibility, saying the intrusion began with a vishing (voice-phishing) attack targeting several Abbott employees that compromised a Microsoft Entra ID single-sign-on account, which was then used to "exfiltrate data from Microsoft Entra, ServiceNow, SharePoint, Databricks, and Coupa" — the actor's leak-site posting claims more than 30 million customer records, medical notes and orders, and set a leak deadline it later pushed to 21 July (BleepingComputer, 2026-07-17). A second, separate claim by an actor calling itself "ShadowByt3\$" alleges compromise of an externally facing LabCentral portal, which BleepingComputer reports houses publicly available technical product reference documents and does not contain proprietary or sensitive customer or business information (BleepingComputer, 2026-07-17). The record counts and the specific SaaS platforms are the actor's unverified claim, not Abbott's confirmation.
