Backups 'no longer effective' for stopping ransomware attacks:
The growth of double extortion – and even triple extortion – ransomware attacks is in danger of rendering common, traditional methods of mitigating the impact of a ransomware hit, such as well-maintained backups, less efficacious, according to a report from machine identity specialist Venafi.
Data collated from Venafi's worldwide survey of IT and security decision-makers reveal that 83% of successful ransomware attacks now involve alternative extortion methods – for example, using stolen data to extort customers (38%), leaking data to the dark web (35%), and informing customers that their data has been compromised (32%). A mere 17% of attacks merely ask for money for a decryption key.
Venafi said that this means that because ransomware attacks now rely on data exfiltration, effective backup strategies are therefore to some extent "no longer effective" for containing a breach.
"Ransomware attacks have become much more dangerous. They have evolved beyond basic security defences and business continuity techniques like next-gen antivirus and backups," said Kevin Bocek, vice-president of business development and threat intelligence at Venafi.
Venafi also found that cyber criminals are increasingly following through on their threats whether or not they get paid. Indeed, 18% of victims had their data leaked despite paying, while more than the 16% who refused outright to pay anything and had their data leaked. Some 8% refused outright, but then had their customers extorted; and 35% paid, but were left hanging, unable to retrieve their data.

Good advice, but usually it's not the NAS or servers themselves which get attacked, but workstations that access the data on daily basis. You can't expect the workstations to be off the Internet when most of the work depends in some way on it.
Proper design of data access policies, permissions, auditing and active monitoring of access patterns is the proper solution. If you detect that one workstation is modifying huge amounts of data, then it's time to check it out, for example. As always proper security is expensive, and most of the time only considered AFTER a huge breach has happened.

Is keeping TWO damn boxes connected to two damn LCDs on same desk SO damn hard?
An Internet connected one for emails, searches, and online timewasting; and another on the internal network where sensitive data are, and no Internet-connected device allowed in.
If something from the sensitive-data network ever need be emailed for some reason, then damn print it out, then scan it in, and send. Or do a photo of the screen and send that. If that is "too hard", then your data are not sensitive enough.

Yes, it is that damn hard. Normal people barely comprehend a single PC, and you expect them to handle two with no method of sending data from one to the other?
Your solution is clearly not a realistic one. We're talking about normal companies handling client data, like internet shops and so on, not NSA state secrets.

Those "normal companies" can choose; either they do NOT gather and keep sensitive client data, or they are fully liable for criminal negligence when the mis-kept data get stolen from them.
If people cannot be bothered to handle sensitive data with proper care, they SHOULD NOT BE HANDLING THEM AT ALL.

Then by the finest capitalist principles they choose not to care unless they are in the EU and are bound by the GDPR rules.
