Ransomware attack by RansomHouse results in a telecom giant, Cell C, losing approximately 2TB of data.
The stolen data includes sensitive information of about 7.7 million customers, such as full names, contact information, ID numbers, banking details, and more.
It is unclear why a telecom provider would store medical information.
Cell C is taking steps to mitigate the damage and has brought in international cybersecurity experts to counteract RansomHouse's actions.
