📰 What Happened
Quest Diagnostics has confirmed that hackers got into its systems and reached patient records. The lab testing giant said it found the break-in on Wednesday. The attack hit Quanum, a system that doctors and hospitals use to order tests and handle billing.
Quanum holds a lot of private data, including test results and billing details. Quest told US regulators that some patient records were accessed. The company said it has called in law enforcement and is still working out how many people were affected.
🔍 The Backstory
Quest is one of the largest lab testing firms in the United States, so a breach there can touch millions of people. It had to report the incident to the Securities and Exchange Commission within days because it is a public company.
Health firms have become a favourite target for criminals. Stolen medical records sell well because they cannot be cancelled like a credit card. This year has already brought a damaging attack on device maker Stryker and a hack at Boston Scientific.
🎯 Why It Matters
Medical records can hold your test results, address and insurance details. Once stolen, that data can be used for fraud for years, so watch for odd bills or messages.
