Can’t install fresh version of Magento

Trying tom install a new Magento with composer:

composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition store

Result:

 [Exception]
  Higher matching version 1.8.0 of magento/composer was found in public repository packagist.org
                               than 1.7.0 in private https://repo.magento.com. Public package might've been taken over by a malicious entity,
                               please investigate and update package requirement to match the version from the private repository

I know Magento released something to detect disparities in pub/private repos, but if this is off a fresh install, what am I supposed to do?
