The email message below with the subject: "Yahoo! Notice: Confirm Your Mailbox," which claims that an automated request to temporarily suspend the recipients’ mailboxes has been initiated, is a phishing scam. The fake email message is being sent by cybercriminals to trick Yahoo users into sending them their Yahoo account credentials, by asking them to click on a link in the same email message that goes to a phishing Yahoo website. The phishing website, which looks exactly like Yahoo's sign-in page, will ask potential victims to sign-in with their Yahoo accounts credential, but once potential victims attempt to sign-in, their Yahoo account credentials will be sent to the cybercriminals responsible for the fake website. The cybercriminals will then use the stolen credentials to hijack their victims' Yahoo accounts and use them fraudulently.

Yahoo users should never click on a link in an email message to sign into their accounts. It is recomended that they go directly to www.yahoo.com or mail.yahoo.com, and sign into their accounts from there. If there is something wrong with their accounts, they will be notified after signing in. Going directly to Yahoo's website is the best way to protect against phishing scams created by cybercriminals to steal online account credentials (user names and passwords).
