Solarwinds accidentally leaked (via Github) the FTP credentials to the infrastructure used to distribute builds in late 2019 [1].

I'd be curious to see if the digitally signed bad versions are similar to digitally signed good versions, i.e. if there's any chance the attacker found/developed a hash collision against an otherwise legitimate build. AIUI it'd be a pretty big deal since it would point to a vulnerability in SHA-256 (which is usually how Windows binaries are signed), but this is apparently a nation state we're dealing with? ¯\_(ツ)_/¯

They did sign it with the key they found there, virus vendors detected fancy bear or such, customer support was in denial and recommended all customer to ignore this warning and disable scanning this binary, whitelist.

You don't need the GRU with such a company. Microsoft Defender would not help. Even a 12 year old from mom's basement could have intruded the nuclear arsenal this way. The nation state allegation came from the stealth CC stuff they found. But apparently someone else also took the invitation via writable ftp.
