Overview
- Quest Diagnostics, which discovered the intrusion on Wednesday, Oct. 21, disabled access to its Quanum Lab Services Manager and said it has stopped the unauthorized activity while investigators assess the impact.
- The company filed an 8-K with the SEC, told federal law enforcement, and hired outside cybersecurity experts to investigate who accessed the system and what records were taken.
- Quest says core lab operations and most ordering channels remain functional and that providers can use paper requisitions or alternate electronic systems to place tests.
- The firm has not disclosed how many patients were affected or which specific data fields were exposed, and it will notify individuals as required by law after the investigation.
- Quanum is used by many clinicians across North America and Quest’s prior breaches in 2016 and 2019 raise the prospect of regulatory scrutiny, litigation and risks such as medical identity fraud if sensitive data is confirmed stolen.
