We have thousands of Supermicro servers...

Although everyone is shocked, panicking, and DHS is trying to cover it up and/or minimize the panic, the public was warned specifically about SuperMicro doing precisely this by both the Gartner Group and the DoD several years ago (at least 6 or 7 years ago).

(We use Dell servers almost exclusively, whose motherboards are mostly made by Intel, but when we whitebox we use ASRock Rack motherboards...but almost everyone else it seems relies on SuperMicro for everything server-side.)

Thanks for the info! We did know about the hack several years ago. Scary that the problem is still occurring.

I have read that all the issues with these mobos is with blade servers. Let's try and keep this thread updated with what we find out. Scary even if we're not using blades.

Perhaps Supermicro will release a list of compromised product. Ya never know.

Might just be false. So far there is no hard proof. 

In the following article, it is strongly suggested that the problem is global, and that Supermicro is being scapegoated by bigger players:
