Seeking to keep details of the vulnerability hidden at least a month to give people time to protect computers from attacks, computer industry engineers that labored in secret to solve the problem, releasing a software “patch” two weeks ago.

“We are in a lot of trouble,” said IOActive security specialist Dan Kaminsky, who stumbled upon the Domain Name System (DNS) vulnerability about six months ago and reached out to industry giants to collaborate on a solution.

“This attack is very good. This attack is being weaponized out in the field. Everyone needs to patch, please. This is a big deal.”

DNS is used by every computer that links to the Internet and works similar to a telephone system routing calls to proper numbers, in this case the online numerical addresses of websites.
