TalkTalk Investigates Data Breach Linked to Supplier

/ 1 min read

🔍 TalkTalk investigates potential data breach linked to third-party supplier. UK telecommunications company TalkTalk is probing a data breach involving a third-party supplier after a hacker began selling alleged customer data online. The company stated that no billing or financial information was compromised and that the number of affected customers claimed by the hacker is significantly overstated. The data, reportedly stolen from the Ascendon SaaS platform, includes names, emails, and phone numbers of subscribers. CSG, the platform provider, confirmed unauthorized access to a single customer’s data but denied any breach of its systems. TalkTalk’s security team is actively working with the supplier to address the situation.
