The lab-testing company told the SEC it discovered unauthorized access on October 21 to Quanum LSM, the system some clients use to order tests and look up results. Quest paused the system, notified federal law enforcement and is still working out how many patients are affected and what data was involved.
Why it matters: medical offices, clinics and their patients across Los Angeles use lab portals like this every day. Breaches like this are often followed by phishing that uses real patient or test details to look legitimate.
One step today: be skeptical of emails, texts or calls about “lab results” or “billing issues,” and log in only through the provider’s official site or app. Practices should turn on multi-factor authentication for every portal account.
