Mail security issues."},"content":{"rendered":"

I’m seeing a lot of issues with Yahoo Mail accounts being compromised, so I\u2019m posting my notes here and will update as I understand the problem better.  An example is when you get e-mail from friends with a single, SPAM URL in the message and it\u2019s sent to 10-15 people (in alpha order) from their Yahoo! Contacts. <\/p>\n

I suggest that you NOT check the box ‘keep me signed in’ when you log into Yahoo Mail (highlighted in red rectangle on screen shot below).  From what I can tell, some web sites with malicious content take advantage of cached Yahoo credentials and send mail with these SPAM links to everyone in your Yahoo contact list. <\/p>\n

I also recommend using “two factor authentication” wherever possible.  Two factor authentication uses something you know (your password) with something you have (phone number, cell phone).  When accessing a web site, you enter your password (something you know), and then are prompted to enter a code sent to your phone (voice), or your cell (text), which are things you possess.  This is used when resetting passwords on your bank or credit card web sites. <\/p>\n

Another option is to consider moving to Google Mail which appears to be more secure, and I know from testing that Google’s two factor authentication is quite comprehensive and I use an Android app on my cell phone to generate a code. <\/p>\n
