A month after the hackers got access to the system, the Interlock ransomware gang claimed responsibility for the attack; the threat actors have also leaked a total of 2.6 TB of data allegedly stolen from the HSCs to their extortion portal on the dark web where it is available for download.

In its website notice, Texas Tech University Health Sciences Centers indicates that the organizations are sending out data breach letters to anyone who was affected by the recent data security incident. These letters should provide victims with a list of what information belonging to them was compromised.

The breach affected 650,000 individuals at TTUHSC’s Lubbock campus and 815,000 at its El Paso branch. As well as causing prolonged disruption to classes and patient services, communication systems, including the Texas Tech Physicians’ patient portal, were impacted.

The Texas Tech University Health Sciences Center and its El Paso counterpart suffered a cyberattack that disrupted computer systems and applications, potentially exposing the data of 1.4 million patients.
