1/ could it be that #SUNBURST introduced #SUPERNOVA, but only to victims of interest (not the whole 18K)?
Abusing #Solarwinds Orion vulns with #SUPERNOVA , attackers can bypass auth and get access to Orion.
From there they get access to cloud cert to Sign #GoldenSAML
2/ If so this explains a lot:
It means no mysterious second actor as originally claimed by Microsoft reducing the complexity of this story
microsoft.com/security/blog/…
3/ it explains why the #SUPERNOVA webshell was not signed (because it's not part of the backdoor payload, but introduced later)
And finally, it tightly connects the method of entry to the #GoldenSAML post exploitation.

1/ IT politics is part of the "physics" of the security problem, much like friction, noise and air resistance in the physical world.
An often overlooked aspect of security solutions is that they empower CISOs to mitigate issues without asking others for help
2/ Per the "Kerberoasting" example mentioned by @jaredhaight, the naive solution would be to just ask service account owners to upgrade password strength.
However, the CISO may have a security solution that monitors Kerberos requests to the DC and blocks massive harvesting
3/ while it might not be the perfect solution, but the CISO can do it right away without asking anyone and buy precious time to fix the root cause of the problem.

1/ Adding details from #NSO Group request for injunction against #Facebook
#NSOgroup
2/ The gist of it: Facebook breached their TOS as it allows blocking only in cases the blocked user actually violated the TOS and requires informing the blocked user
3/ some of the plaintiffs were blocked from both #Facebook and #instagram, while others were only blocked from FB
