The email message was NOT sent by Microsoft or Yahoo and is a phishing scam created by cybercriminals to steal Microsoft, MSN, Hotmail, Live, Outlook, and Yahoo usernames, and passwords. Therefore, recipients of the fake email message are asked not click on the links or follow the instructions in it. Microsoft or Yahoo email users who have received similar emails and who want to know if there is something actually wrong with their accounts should go directly to www.outlook.com or yahoo.com and sign into their accounts. If there is something wrong, or if there is something that needs to be done on their accounts, they will be notified after signing in. It is recommended that Microsoft Hotmail, Live or Outlook users never click on a link to sign into their accounts. They should go directly to www.outlook.com, www.hotmail.com or www.live.com sign-in from there instead. And, Yahoo users go directly to mail.yahoo.com.The "We Have Detected Unusual Activity With Your Yahoo and Microsoft Account" ScamFrom: "Yahoo Accounts" <41019353.E9439FFCA25C570FDBD420tuwgmtbbmior@kwrthjwikhyo.com>Date: December 6, 2017 at 2:15:31 PM CSTSubject: We Are Blocking Your IPWe Have Detected Unusual Activity With Your Yahoo and Microsoft Account on Your ComputerLogin Has Occurred on 12/6/2017 @ 7:53 AM ESTFrom IP: 34.125.12.1 Geo Location Found: Eastern RussiaIf This Was Not You Please Call the Microsoft/Norton Joint Security Team(Be at your computer as it is at risk)1 855-203-6080Microsoft and Yahoo users who have already been tricked by the phishing scam are asked to change their passwords immediately before their accounts are hijacked and used fraudulently.
