No worries, guys, the webstore has NOT been hacked.
See yourself:

Our webstore page which contains links to the webstore, has been hacked. All Joomla pages have been hacked because we used 1.5.04 and the current version is 1.5.10 so we missed a few security updates.

Please don't worry, this is just an automated hacker thing, they do not get any credit card info or stuff like that because we don't have any CC data on our server at all.
