U.K. telecoms giant TalkTalk has confirmed that it is investigating a data breach after a hacker claimed to have stolen the personal information of millions of customers.<\/p>\n

In a post on a popular cybercrime forum seen by TechCrunch, an individual using the alias \u201cb0nd\u201d claimed to have stolen the personal data of more than 18.8 million current and former TalkTalk subscribers. This data, which the threat actor is offering for sale, supposedly includes customer names, email addresses, IP addresses, phone numbers and subscriber PINs.\u00a0<\/p>\n

In a statement to TechCrunch, TalkTalk spokesperson Liz Holloway confirmed the company is investigating the data breach, but said the 18.8 million figure claimed by the hacker is \u201cwholly inaccurate and very significantly overstated.\u201d<\/p>\n

TechCrunch understands that TalkTalk currently has app<\/a>roximately 2.4 million customers.<\/p>\n

\u201cAs part of our regular security monitoring, given our ongoing focus on protecting customers\u2019 personal data, we were made aware of unexpected access to, and misuse of, one of our third-party suppliers\u2019 systems,\u201d Holloway told TechCrunch. \u201cOur Security Incident Response team are continuing to work with the supplier regarding this matter and protective containment steps were taken immedia<\/a>tely.\u201d<\/p>\n

Holloway declined to name the third-party supplier, but screenshots shared by b0nd suggest the data was stolen from CSG\u2019s Ascendon platform, which TalkTalk uses for subscription management. <\/p>\n

CSG did not immediately respond to TechCrunch\u2019s questions.\u00a0<\/p>\n

TechCrunch understands that the personal details of a small subset of TalkTalk customers are stored in Ascendon. Holloway confirmed to TechCrunch that \u201cno billing or financial information was stored on this system.\u201d<\/p>\n

TalkTalk was previously fined \u00a3400,000 after a 2015 data breach in which hackers stole the personal data of 157,000 customers, including some financial information. The U.K.\u2019s Information Commissioner said at the time that TalkTalk had failed to implement \u201cthe most basic cyber security measures,\u201d enabling hackers to \u201cpenetrate its systems with ease.\u201d<\/p>\n<\/div>\n
