Hackers in Microsoft's webmail breach could read some users' messages


For some users, that Microsoft webmail breach was worse than first thought.


Microsoft has confirmed a Motherboard source's claims that the hackers had access to a portion of the email content, not just email addresses and subject lines.


It's not clear if the intruders read the email before Microsoft blocked access, but the company told the The Verge in a statement that the subset received "additional guidance and support."


The attack was apparently part of an effort to hijack the accounts of iCloud users, making it possible to disable the Activation Lock that prevents thieves from wiping a stolen iOS device's data.


However, Microsoft has hundreds of millions of webmail users with Outlook.com, Hotmail and MSN accounts.


Even a fraction of a percent could still represent a large number of compromised accounts.
