A 17-year-old has appeared in court today and admitted seven offences in relation to last October's TalkTalk hack.
The teenager, who cannot be named for legal reasons, was arrested in Norwich in November 2015 and charged with breaching the Computer Misuse Act 1990.
The attacks on TalkTalk resulted in the personal data of almost 160,000 people, and the banking details of 15,656 people, being accessed.
TalkTalk was fined £400,000 for the breach, which was discounted by 20 per cent for early payment, in an attack that Christopher Graham, information commissioner at the time, described as a "car crash".
The attack exposed lackadaisical security at the internet service provider, which has more of a reputation for "value" than "quality", and cost the company £42m in total.
The teenager will almost certainly be handed a custodial sentence, and should probably be thankful that he chose a British organisation to attack, rather than an American one, and that he's therefore not being extradited to the US.
As many as five suspects across the country were arrested following the attacks, and it's not clear whether they are linked or whether they sought to take advantage of the original attack by, for example, some form of cyber extortion.
The hacker's day in court comes as TalkTalk warned that the firm still struggles in its core broadband subscription market in the wake of the attack. The company lost 98,000 retail subscribers in the first half of the year, but gained 69,000 via wholesale deals with third parties, resulting in a net loss of 29,000 subscribers.
However, these wholesale customers are much less profitable than retailers that subscribe to TalkTalk directly.
The loss of customers followed a big exodus to more competent ISPs immediately following the attack.
The company managed to post a £46m pre-tax profit in the six months to the end of September, largely as a result of slashing marketing spend prior to an October relaunch.
TalkTalk said that CEO Dido Harding claimed that the company had switched its marketing guns back on in a bid to staunch the flow of customers to Sky, Plusnet, BT and other rivals.
