Yahoo!'s UK limb has finally been handed a £250,000 fine for the 2014 cyber attack that exposed data of half a million Brit users.

Russian hackers broke into Yahoo!'s servers and slurped info on circa 500 million international account holders, including names, email addresses, phone numbers, birthdates, hashed passwords and encrypted or unencrypted security questions and answers.
