Yahoo and auction web site eBay are teaming up to crack down on fake email. EBay is using Yahoo’s anti-phishing technology to support domain keys according to the BBC News Technology section. Domain keys block fake email by verifying sender with a digital signature.
DomainKeys Identified Mail (DKIM) will be offered to Yahoo Mail users to keep out unwanted mail. John Kremer, vice president of Yahoo Mail told Reuters “It is a big step forward for consumers in defense against the bad guys.”
Paypal and eBay are the two most targeted companies for phishing emails according to Trend Micro. It is estimated that one out of every 173 emails sent worldwide contains phishing attacks.
DKIM detects encrypted digital signatures to verify the origin of the message. However for the DKIM technology to be effective, both the user sending and the user receiving the email need to have their mail services signed up to DKIM.
Security analyst with Forrester Research, Chenxi Wang said to Reuters “Two years ago if you asked companies whether they were using e-mail authentication, most people wouldn’t have cared. The industry is slowly coming around.”
