O2 customer data for sale
Hackers have managed to gain access to O2 customer data, which has been put up for sale on the dark web. Data was likely obtained by using usernames and passwords which were stolen from gaming website XSplit, 3 years ago. These were then used to gain access to the O2 accounts. Once the login credentials matched, the hackers could gain access to the O2 customer data using a process called “credential stuffing”.
Hackers gained access to all sorts of sensitive data including dates of birth, emails, phone numbers and passwords. This ultimately relies on password reuse. Cases such as this one just highlight the true dangers of password reuse.
This case goes to show using the same usernames and passwords across multiple sites isn’t a good idea. Also using passwords that aren’t complex enough and are easily guessable is also a bad idea.
