I just got called by a hacker/scammer trying to steal my hotmail account

http/www.tomshardware.com/news/gmail-hotmail-yahoo-email-hacked,31743.html Was a breach that hit the news a couple days ago.

He was not only trying to steal your e-mail account, he's probably trying to steal your identity and may have already gained access to your email account since a) an amazon reset code would be sent to your email, b) to know the number of logins or attempts he'd need to access your email, c) he may have found your phone number in one of your emails, or maybe from some acquaintance's email or may know your full name and location and ultimately your phone number from browsing through your emails (*)... also many programs carry potentially unwanted programs piggy-backing on them that can steal personal information. So, the means to get your personal information are quite a few for a cybercriminal.

It would be wise to change all your passwords, and scan your computer for bugs and hacking tools to protect your private information, credit and banking information as well as those of your family, friends and acquaintances whose names may be found in your computer or emails.

Go through a few tips on online security.

Because it's supposedly a single hacker and the guy did only ask for less than a dollar and liking his social media pages. As long as you have 2 step verification, they couldn't even get into your accounts.

Have you contacted Hotmail directly to notify its admins of what happened? It could be that this guy calling you was the real deal. After all, it doesn't sound like you actually gave him any information, and your account got hijacked anyway.
