You've no doubt received an email or two (or thirty) telling you that your PayPal account has been compromised. Or that someone has a question about an item you're not selling on eBay. And maybe you even fell for it (hey, it looked official enough) and unwittingly gave up your precious password to digital thugs who swiped it and ran amok with your identity.
Thugs, beware! As of today, it'll be much harder for these malcontents to scam unsuspecting Yahoo! Mail account owners. We've teamed up with eBay and PayPal to become the first Web mail service to block the delivery of unauthenticated eBay and PayPal emails, reducing your risks of receiving phishing scams or fraudulent emails. Our weapon is a technology Yahoo! spearheaded called DomainKeys, which uses cryptography to verify the domain of the sender. In overly simplified terms, if the email's originating domain ain't really eBay.com or PayPal.com, it ain't going through. More detailed and accurate description here. The technology will be rolled out globally over the next several weeks to all Yahoo! Mail users.
DomainKeys is seeing terrific industry adoption, in part due to the widespread consensus about the promise of proposed internet standard DomainKeys Identified Mail. About 40% of the email we deliver on Yahoo! Mail is signed with DomainKeys. And we hope today's news gets the attention of information security officers at some of the more obvious phishing targets so we can help protect even more consumers from the havoc these scams wreak. We're already actively working with many financial institutions, for example, and hope to continue the momentum.
We're doing our best to make your inbox safe from bad guys. We want to make sure they don't get the best of you.
