Twitter unveils weapon vs. email impostors

By Benjamin Pimentel, MarketWatch

SAN FRANCISCO (MarketWatch) ? Twitter on Thursday said it has begun using a technology to make it harder for impostors to send Twitter members forged emails purportedly from the social microblogging site.

Twitter?s DMARC aims to combat email imposters.

The new system, called DMARC, for ?Domain-based Message Authentication, Reporting & Conformance,? is aimed at making it ?extremely unlikely that most of our users will see any email pretending to be from a Twitter.com address,? Twitter said in a company blog post.

?While this protocol is young, it has already gained significant traction in the email community with all four major email providers ? AOL /quotes/zigman/577531/quotes/nls/aol AOL -0.69% ?, Gmail /quotes/zigman/93888/quotes/nls/goog GOOG +0.28% ?, Hotmail/Outlook /quotes/zigman/20493/quotes/nls/msft MSFT -1.24% ?and Yahoo Mail /quotes/zigman/59898/quotes/nls/yhoo YHOO -0.60% ?? already on board, rejecting forged emails,? Twitter said.

The announcement follows the high-profile hacking of the Twitter pages of Burger King and Jeep, and admissions by Facebook Inc. /quotes/zigman/9962609/quotes/nls/fb FB -4.37% ?and Apple Inc. /quotes/zigman/68270/quotes/nls/aapl AAPL -0.55% ?that their networks got hacked.

In the wake of the Twitter page hacks, the company on Tuesday posted a ?friendly reminder? to users regarding password security.

?Watch out for suspicious links, and always make sure you?re on Twitter.com before you enter your login information,? a company blog post said. ?Be cautious when clicking on links in Direct Messages.?
