We've looked forward to this release since March and have incorporated these sub-techniques in our threat modeling process. We've found the increased technique fidelity and the ability to address more nuanced adversary behaviors to be really impactful.
From MITRE ATT&CK:
"We’re excited to announce the release of ATT&CK with sub-techniques! We released a beta preview of the content in March, and now (with some small updates and fixes) it has become the current version of ATT&CK. Our hope is that this sets up ATT&CK on a much more sustainable path for the years to come. You can find the new version of ATT&CK and what's changed on our website (https://lnkd.in/e_DrbMC).
We've also released a new blog post pulling together what's changed, why, and how to shift to this new version of ATT&CK."
