After we reported the vulnerability, both automakers fixed it within about two hours and rotated the affected credentials. The affected systems served customers in multiple regions; we tested the complete chain only with US accounts and vehicles.
and I suspect there may have been a ninja edit- I swear blind I read a throw away line about why they were keeping the company name suppressed an hour or so ago, now I cannot find it in either article. As I recall, they "normally would disclose" but "times are busy and security folks are hard pressed" (paraphrasing) - they were giving the auto folks a bit of leeway for a bit (likely by request).Often when the situation is "Most makers are 1/10, but we're 0/10" a small amount of effort can get you to 4/10 and until the attackers up their game you look stellar, even though in reality you're still doing a poor job, everybody else was much worse
