Royal Mail is currently investigating a data breach after a threat actor leaked over 144GB of data allegedly stolen from its systems. The breach is believed to have originated from a compromise at Spectos GmbH, a third-party data collection and analytics service provider for Royal Mail. The leaked data includes sensitive information such as customer personally identifiable information (PII), internal communications including Zoom meeting recordings, operational data like delivery routes, and marketing infrastructure data including Mailchimp mailing lists.

The investigation is ongoing to determine the full extent of the breach and its potential impact. Royal Mail has stated that there is currently no impact on operations. The incident serves as a stark reminder of the vulnerabilities inherent in modern supply chains and the critical need for robust vendor management and security protocols. The breach highlights the potential for identity theft, phishing attacks, and reputational damage arising from compromised vendor access.
