Case Study: Northeast Healthcare Company achieves zero breaches and remediates Qbot with Carbon Black (Cb Protection)

Healthcare Company Prevents QBot Breach with Carbon Black

A major Northeast healthcare company was hit by the Qbot virus, which compromised about 4,000 PCs, triggered a Code Yellow HCIS incident, and caused six hours of clinical downtime. After the anti‑spyware tool CounterSpy failed to remediate the infection, the organization turned to Carbon Black and its Cb Protection product for endpoint security.

Carbon Black deployed Cb Protection across 4,800+ endpoints, eliminating all Qbot variants, restoring systems, and mitigating the risk of federal fines and reputational damage. Since the deployment Carbon Black reports zero breaches despite daily attack attempts, with measurable impact including full remediation of infected machines and continuous blocking of new Qbot variants.
