​TalkTalk has been urged to take its cybersecurity more seriously after failing to take action to fix a website vulnerability caused by an anonymous hacker . Sky News journalists were told of the scripting error and shown how it allowed the hacker to take control of the website and potentially target users to steal their data . The firm was told to "be more diligent and more vigilant", and was fined a further £100,000 after data belonging to 21,000 customers was exposed to "rogue" staff at a call centre in India. The company fixed the problem after being contacted by Sky but the hacker said TalkTalk was first made aware of the issue in 2016 and had not responded to demand it be addressed .
