Re: Pending Review
Disaster Recovery plan.  Business continuity.  Your six points do not address this one.  After September 11, and I am a survivor of the south tower so I know something of the subject, my manager became a certified expert in this area.  It is crucial that IT departments have a plan, test it and update it every six months.  It is crucial to have offsite, rotating backup media.  It is crucial to consider that at 2:30 am working on a data center restoration is a mental nightmare.  TEST the plan ensures that staff knows what they ARE doing.  Our data tapes for Aon went offsite on September 10 and thus we had our portion of the network up FAR faster than Risk services.  They were months recovering data.  Now the destruct of a data center is AS bad as ransomware if not worse if not addressed.  So once again plans gone bad and rebuild of everything seems the only process known.  I have said this a thousand times here. HAVE A PLAN, TEST AND UPDATE.

Re: Pending Review
Second the off-site backup. Datto Box (cloud) might be one place to start. We do a "fire drill" every year - stress test UPS's, Restore servers from the cloud, restore desktops, restore NAS's Kill the power to the building to insure that the on-site generator kicks in and the auto cut-over operates nominally.

Desktops are backed up concurrently with timestamped histories

Same with servers.

It all goes out to the cloud.

We're a tiny little outfit. Others should try and do at least these things. Especially larger organizations.

I hope you all land on your feed at the firm. Good luck.

Re: Pending Review
Testing a plan has a real purpose beyond finding out what works and does not work.  These are critical of course but i will guarantee you that making such discoveries at 2:30 AM when nobody is thinking is FAR harder than finding out in the afternoon under a planned environment.  I'm not awake at that hour.  Nobody is.  And when you have real work to do make sure it is a known variable.  Because if it is not tested, then mistakes will happen and a recovery plan can destroy even more material than intended.   Or make it impossible even to recover.  At 2:30 am I am on a serious coffee burn!!!!

Different scales
It is essential to know that attacks do not often target finances alone. Sometimes their intention is just to destroy or at least slow down operations. This is basically the reason why we need to stop any potential attacks regardless of their individual scale before they can even hit.

More Definitive Security Required
Additionally, for critical industrial infrastructure we are finding success with a more effective application process and filesystem monitoring in conjunction with fileless attack protection and a full-scale memory defense.

fileless attack protection and a full-scale memory defense. It sounds like fileless attacks are becoming common. Good point.

Ransomware
Ransomware-related events have declined 91% year over year and the number of new ransomware families in the marketplace has declines 32%, Some good news. May be we are becoming more carefull clicking the links anymore.

consequence
"The consequence is that in many cases, the victim may not even be able to view the ransom note, let alone attempt to comply with any ransom demands," Interesting. What would be the purpose of attach in that case I wonder.

re-imaging
The goal is "to further isolate the affected computer and to complicate recovery, necessitating direct local intervention." This beings up image to my mind. Less about recovery more about re-imaging.

Copy files
"indicates the actors simply manually copy files from computer to computer," They would need network interface for that to work.

AD
An example is where an attacker might have access to the Active Directory infrastructure Once you ave AD access you can even deploy ransomware to other part of the network.
