Here We Go Again – Another Round of Yahoo Accounts Hacked
At this point, if you're still using Yahoo for your email and messaging then you're just asking for no privacy. They just announced another breach of many user accounts.
As Yahoo calls it, it's a "state-sponsored actor" breach. The way the hackers got into your accounts was through cookie-forging. Cookies are a file that's placed on your computer to associate you with an ID to enter without having to login. When a user's cookie is forged by another user, it essentially will bring them directly into your account.
The folks at Yahoo aren't saying exactly "how many" accounts were breached, but it's presumed to be in the billions of users in a period of 2015 to 2016. Hackers had access to user's email addresses, security question, and birth dates.
It's unknown how many Yahoo users still exist in Minnesota, but it's very likely you know somebody who's still using their service. You may want to forward this to them, or even better, tell them to change their password. I had Yahoo mail for exactly 6 months, and will never go back. I appreciate what Gmail has to offer, and have never had an issue.
