It’s just been announced that Yahoo! experienced a data breach that caused more than 1 billion accounts to be compromised.  Hopefully everyone knows not to store or transmit sensitive information on ‘public’ email systems, meaning email providers that give you a ‘free’ account as they’re often the target of hackers.  Also your emails are searched for marketing and sales opportunities.  In any regards, if you have a Yahoo! account, keep a lookout for suspicious activity – and consider moving on to a different platform.
