TCS Denies Customer Data Breach After Employee Data Leak Claims
A big technology company called Tata Consultancy Services, or TCS, helps other companies with their computers.
Someone sent TCS alerts saying that some information about its workers might have been seen by people who should not see it.

TCS explained that the information mentioned in the alerts was very old, more than four years old.
It said the information was only basic details about its workers, not anything secret.
TCS also said its own computer systems were not harmed, and it has had safety measures in place for over two years that work against this type of attack.
