Yahoo said on Wednesday that it had discovered another major cyber-attack.
They said that data from more than 1 billion user’s accounts was compromised.
“Don’t panic,” security expert Graham Cluley told the BBC, although he does add that there are plenty of reasons to be concerned.
The problem is that they have only just found out that this happened and it happened in August in 2013. 3 years ago!
Yahoo has also said it is investigating a more recent, separate issue that might have made some accounts accessible without passwords.
This means that there is another problem that Yahoo isn’t telling everyone that could have something to do with the hacking of the accounts. Another problem is that they have only just told people about the hack now so if they would have said about this in 2013 this might have been sorted but it’s a been 3 years so loads of more information has been compromised. The hacker(s) could have got used to the system and found out more ways to access the private information.
“Your email account is the central hub of your entire online existence – if they own that they can ask for password resets on other accounts you have online as well,” explains Mr Cluley. This isn’t very reassuring for people, this just makes them more worried.
Yahoo own many accounts but Yahoo has said, though, that accounts for Tumblr – which it also owns – would not have been affected.
