How do you know they use TeamSite? A similar hack occurred against TicketMaster. I wonder if they use TeamSite as well. Maybe a 0day?
How can you tell it is Teamsite?
I love it how big companies still use legacy CMS like Teamsite thinking it is too expensive to move to something modern.
If you have a large customer-facing website retail website, redoing the whole thing in something "modern" (which will only be "modern" for a year or so) is actually very expensive. Have you ever migrated a non-trivial website from one platform to another?
Uhh, yeah, it wasn’t such a bad choice 20 years ago. I had no idea they were still using it lol. Interwoven we called it back then.
