Royal Mail is investigating claims of a security breach after a threat actor leaked over 144GB of data allegedly stolen from the company's systems.
While the British postal service has yet to confirm that its systems were breached, a spokesperson told BleepingComputer that Royal Mail is aware of an incident at Spectos GmbH, a third-party data collection and analytics service provider.
"We are aware of an incident which is alleged to have affected Spectos, a supplier of Royal Mail. We are working with the company to investigate the issue and establish what impact there may be regarding their data," BleepingComputer was told. "We can confirm there has been no impact on Royal Mail operations and services continue to function as normal."
Spectos also confirmed in a statement shared with BleepingComputer that its systems were breached on March 29, and the attackers gained access to customer data.
