`` There have not been any breaches Attack.Databreach in any of Apple 's systems including iCloud and Apple ID , '' an Apple representative said in an emailed statement . `` The alleged list of email addresses and passwords appears to have been obtained Attack.Databreach from previously compromised Attack.Databreach third-party services . '' A group calling itself the Turkish Crime Family claims to have login credentials for more than 750 million icloud.com , me.com and mac.com email addresses , and the group says more than 250 million of those credentials provide access to iCloud accounts that do n't have two-factor authentication turned on . The hackers want Apple to pay Attack.Ransom $ 700,000 -- $ 100,000 per group member -- or `` $ 1 million worth in iTunes vouchers . '' Otherwise , they threaten to start wiping data from iCloud accounts and devices linked to them on April 7 . In a message published on Pastebin Thursday , the group said it also asked for Attack.Ransom other things from Apple , but they do n't want to make public . `` We 're actively monitoring to prevent unauthorized access to user accounts and are working with law enforcement to identify the criminals involved , '' the Apple representative said . `` To protect against these type of attacks , we recommend that users always use strong passwords , not use those same passwords across sites and turn on two-factor authentication . '' However , the unusually high numbers advanced by the group are hard to believe . It 's also hard to keep up with the group 's claims , as at various times over the past few days , it has released conflicting or incomplete information that it has later revised or clarified . The group claims that it started out with a database of more than 500 million credentials that it has put together over the past few years by extracting Attack.Databreach the icloud.com , me.com and mac.com accounts from stolen databases its members have sold Attack.Databreach on the black market . The hackers also claim that since they 've made their ransom Attack.Ransom request public a few days ago , others have joined in their effort and shared even more credentials with them , putting the number at more than 750 million . The group claims to be using 1 million high-quality proxy servers to verify how many of the credentials give them access to unprotected iCloud accounts . Apple provides two-factor authentication for iCloud , and accounts with the option turned on are protected even if their password is compromised Attack.Databreach . The latest number of accessible iCloud accounts advanced by the Turkish Crime Family is 250 million . That 's an impressive ratio of one in every three tested accounts . The largest ever data breach Attack.Databreach was from Yahoo with a reported 1 billion accounts . `` At best they ’ ve got some reused credentials , but I wouldn ’ t be surprised if it ’ s almost entirely a hoax . '' Hunt has n't seen the actual data that the Turkish Crime Family claims to have , and there is n't much evidence aside from a YouTube video showing a few dozen email addresses and plain text passwords . However , he has significant experience with validating data breaches Attack.Databreach and has seen many bogus hacker claims over the years . To be on the safe side , users should follow Apple 's advice and create a strong password for their account and turn on two-factor authentication or two-step verification at the very least
