Earlier in April, a number of Microsoft Outlook email users’ email accounts were accessed by hackers, seemingly intent on stealing the users’ cryptocurrency.

Motherboard is reporting that not only the meta data attached to the emails was hacked, but content too. Once a hacker has access to a user’s emails, then it’s an easy thing to change passwords to any other online accounts which are confirmed with that email.

This is exactly what happened to one user. Jevon Ritmeester has had the equivalent of 1 Bitcoin (approx. $5,200 value) taken from his Kraken exchange account. Ritmeester only realised that he’d been hacked after he checked the trash of his email account, and saw that his passwords had been changed without his knowledge.

A Microsoft spokesperson said: “Customers who believe they have been impacted beyond what was outlined in the company’s notification should contact the Microsoft support team for assistance.”

This is another reason to have two factor authentification set up on any accounts that you own. A pain in the a** if you lose your phone of course, but better than losing your bitcoin.
