tell me about it.. it happened to me (who's never been hacked, ever- and had my yahoo! account for over 15 yrs) which then same hack affected family members as well. I don't use an email client, I keep emails on their servers. After said hack, my yahoo! email settings were then changed as well
to their newer and crappier format which one canNOT change back to the old & more readable formatting way. This infuriated me much more than the stupid spamming.
One terrible effect of it was a family members yahoo mail is also received on her smart phone, which somehow the hack changed her AT&T settings! One other reason why I do not own or use a smart phone, nor even have a cell phone account.
Don't use those email clients (Windows Live et al) as those messages are stored on your computer instead of staying on the yahoo server, but to most if not all of you guys on this board that advice is probably just preaching to the choir. I'd also like to state that I don't open unknown files or click links in email so I wonder how this hack happened?
About to read the huffpo link I hadn't seen- but this yahoo hacking seems a bit more than just a simple annoying spamming deal. It's gone into my basic settings on my account also, and my family's phone settings. I caught it quickly and changed my passwords of course and I hope this does not happen again.
I'd like to find a good web based email provider (free) that does not have the option of signing in with other accounts- seems all of the providers I find have the "Sign in with your Google/Facebook/etc" I do not trust those types.
