Last week, one of the UK's largest providers of pay-TV, landline and broadband services, TalkTalk, revealed that its website had been subjected to a "significant and sustained cyberattack". The company admitted that customer data, including banking details, "may have been accessed", and its CEO revealed that she had received a ransom demanding a payment in Bitcoin.
London's Metropolitan Police, whose Cyber Crime Unit (MPCCU) has been leading the investigation into the attack, said today that an arrest has been made.
In the last few hours, the Police Service of Northern Ireland (PSNI), working with detectives from MPCCU, arrested a 15-year-old boy, after gaining a warrant to search an address in County Antrim, Northern Ireland. The boy has been detained on suspicion of offences related to the Computer Misuse Act, and will be interviewed later.
The arrest doesn't bring an end to the investigation, though - the PSNI's Cyber Crime Centre and MPCCU will continue to look into the cyberattack in conjunction with the UK National Crime Agency.
