# [Myriad Genetics detects unauthorized access, temporarily suspends testing operations](https://securteksecurity.com/news/myriad-genetics-unauthorized-access-suspends-testing-operations)

   5th Nov 2026  

Myriad Genetics disclosed in a Form 8-K filed with the SEC on November 5, 2026 that it detected unauthorized access to its information technology network on November 2, 2026. The company temporarily suspended its testing operations and order management systems while it contained the activity, reset certain system credentials, and engaged external experts. Most systems have since returned to normal operations, and the company says it does not currently believe the incident will have a material adverse effect on its business. No affected count has been disclosed, and whether any patient records were accessed is still under investigation, so this item is prepared as a Cybersecurity item and not a Breaches add.

This report rests on a single reporting chain: every account of the incident found in this cycle derives from Myriad Genetics' own SEC filing, and no independent second outlet has reported facts beyond that filing. The figures and status above are the company's own statements in that filing, and this item will be updated when independent confirmation or further disclosure appears.
