02 customer data for sale on dark web, claims the BBC
Data belonging to 02 customers is being sold by cyber-criminals on the dark internet, a report by the BBC claimed yesterday.
The Victoria Derbyshire programme said it was shown adverts for the data by an "ethical hacker", with the contents believed to come from the hacking of gaming website XSplit in 2013.
Details from that breach were matched with O2 accounts in a practice called "credential stuffing", in which the details are used to log in to other websites.
Among the information allegedly for sale was customers' phone numbers, email addresses and passwords, though O2's security systems were not breached as part of the process.
The firm said in a statement it was aware of the situation and had notified police. "We have not suffered a data breach," the telecoms company added.
The dark web is a subsection of the internet that can only be accessed via specialised software. It is used for a large number of illegal activities, including the sale of stolen data and drugs.
