TalkTalk investigating data breach after hacker claims theft of customer data | TechCrunch
Briefly

TalkTalk is conducting an investigation into a suspected data breach after a hacker claimed to have stolen personal information from over 18.8 million customers. The company refuted these claims, stating they have approximately 2.4 million customers. The breach reportedly resulted from unauthorized access to a third-party supplier's system called Ascendon, which handles subscription management for TalkTalk. No billing or financial data was compromised. TalkTalk's proactive security measures and ongoing cooperation with the supplier's response team underscore the seriousness with which they are addressing the situation.
TalkTalk is currently investigating a significant data breach claimed to involve the personal information of millions, although they contest the hacker's figures as exaggerated.
The data breach involved unexpected access to a third-party supplier's systems, with indications that customer details were extracted from CSG's Ascendon platform.
