At the same time, it's just the source-code for a WordPress (which is already public).
It also contained passwords and such though so he could've done worse.
um eBay runs on Wordpress?
No, ebay as the auction site does not. ebay.co.jp does
That seems kinda strange. What business is ebay.co.jp in then if they don't run an auction site?
after translating the site, it appears to be purely informational with the intent of helping/convincing Japanese businesses to start cross border eCommerce using ebay.
If ebay doesn't offer an award, doesn't e.g. google offer one? iirc they have a bug bounty program for stuff that they don't own as well.
Its more for things that affect an OS or browser I thought but I could be misremembering, project zero or whatever is relevant to their efforts in securing software.
There’s IBB; the internet Bug Bounty. But it’s for widespread open source software. Typically FOSS that isn’t well funded yet is critical to massive parts of the internet. Popular libraries, email & DNS infrastructure etc.
Ebay being a private company with boatloads of money is definitely not a part of that.
