As I repeatedly point out, lateral movement may be exploits/vulns like Eternalblue or Bluekeep, but much more it's through credential stealing and logins, without exploits/vulns. This is now the #1 concern for all cybersecurity: how to handle credential stealing.
If "credential stealing" through such tools like mimikatz isn't your cybersecurity organization's #1 concern, then you are doing it wrong. If you are instead focused on anti-virus and vuln patching, you are doubly doing it wrong.
You've patched all your important systems against the Bluekeep vuln, and thus think you are secure. But that still leaves unimportant systems open to exploitation, at which point credential stealing can be used to move laterally to the important systems.
That above story is about a phishing attack. The flaw wasn't that the user infected themselves, the story is how such desktops have such poor security that allows credential stealing.
Q: How about end user training/education?
A: It's impossible to tell good phishing emails from legitimate emails. Thus, you can only train users to spot bad phishing emails. That's of limited usefulness.
Anyway, this thread is nothing new. It's what I've been saying for years. I'm just pointing out this latest story "It started with a phishing email, but the damage was due to lateral movement (probably of the mimikatz/psexec style)".
