You have to remember that eBay is an ancient tech company run by the old MBA types that didn't really understand what value to place on engineering. All their internal systems are maintained by vendors, VARs, and contractors. So weird stuff like the ebayinc.com domain is to be expected. As is this hack. Also it'd be interesting to know how it was detected, and how the extent of access was determined. But if my prediction is correct, we will never see a truly open blog post about it. First, because it's not clear to me that eBay "infosec" is up to the task. Second, because eBay believes more in compartmentalization, secrecy, misdirection etc. than 'openness'.
