Sorry, but you're wrong: "Stop paying ransoms" is the only long term solution. As long as there is a profit in it, they will keep doing it - and some of them aren't too scrupulous about "encryption" rather than "randomization".
If your company doesn't have a good disaster recovery plan which includes a good, solid backup regime, then you are elephanted anyway - it's not just ransomware that can ruin your day. Even in the days of paper, companies went bust because of fires which meant they had no idea who owed them money and who didn't. If you don't prepare for a problem in your core systems - be they paper, people, or computers - then one day you are going to get bitten, and bitten hard.

True an effective backup is required, but if they don't have that and they have contracts to fulfil then it's pay or die, those are the only 2 options, there is no in-between.
The very next step should be to fire the entire IT department and walk them right out the door (perhaps less practical but they should be damn close to it... the in-charge for sure should be instantly terminated.)

Wrong. In the long run, especially if word gets out that the security isn't there, it's "pay AND die".
And firing your entire IT department makes no sense at all. That's just stupid to have your ENTIRE knowledge base walk out the door. Yes, they need training. Yes, they need network and security consultants.
NO, they do NOT need to be lined up and executed. That solves NOTHING as you'll be stuck without an IT department, hiring new people, and having them spend a sh*t ton of time retrain themselves on your environment and reworking it.

Wrong. You're getting rid of your ENTIRE IT department, not the people responsible for the security. That means all of your application and data knowledge goes out the door too. What did they do to deserve such treatment?
You're putting the entire IT department in one bucket. You're also doing it with the discussion here. We say one thing and you drop it into an "all or nothing" bucket. That's the wrong way to think about things.

Have a solid image backup in place that runs nightly, swapping media every day.
Then upon infection of any kind you can just restore from yesterday.

You're right. Protecting yourself against Ransom attacks is not that complicated, even for people who are not totally computer savvy.
Also: I have a second drive in my machine where I store all my data. Data can be backed up by simple copying to a normally disconnected external drive. My systems drive is only for Windows and applications. This means my systems drive images are slim and trim and not bloated with data.

What can a particular day of the year bring? Over time... many different things and emotions.
Many years ago, today, my great-grandfather passed on. It was long before I was born, but my grandmother - his daughter - wrote a couple of books about her life and said what a sad Christmas it was for her.
As a child, we would spend Christmas Eve with my grandparents, those mentioned above, who lived next door. That is when all of the cousins would gather at their house. What I remember from the house is a coffee table with blue glass - no idea what happened to it, but that is my I remember from those nights.
On this day, in 1990, I traveled to my home town to spend Christmas with my parents; I didn't know then it would be my last Christmas with my mother; she passed 4 weeks later. I am grateful for the time I had with her and cherish the memories of that Christmas.
On this day, 14 years ago, I asked my now wife to marry me; she stills says she didn't say, "Yes", but she did say, "I do".
So, whatever a day may bring over time, it will be mixed with various emotions and memories; I hope and pray that you can find something pleasant in each day to remember.

I had to think of my grandmother (father's side) too these days, especially her cooking which was fantastic. No wonder as she was of Belgian origin. She made a very good Flemish stew, called 'hutsepot', which is something totally different than the Dutch 'hutspot', the recipe seems to date way back from the 13th century: Hochepot - Wikipedia[^]

At least once a year we all should be grateful for not having forgotten to check the Jesus nut:
YouTube[^]
This particular Jesus nut is not a religious fanatic. It's the nut that holds a helicopter's main rotor on the shaft[^].
And I just love the song in the video ("If that jesus nut comes off, you can kiss your a** goodbye.")

I'd like to see someone beat this algorithm for true randomness. 
class Program
{
static void Main(string[] args)
{
for (int i = 0; i < 10; i++)
{
var random = BitcoinRandom().Result;
Console.WriteLine(random);
Thread.Sleep(15 * 1000);
}
}
static async Task<double> BitcoinRandom()
{
var client = new HttpClient();
var response = await client.GetStringAsync("https://api.coindesk.com/v1/bpi/currentprice.json");
var data = JsonConvert.DeserializeObject<BitcoinInfo>(response);
return data.Bpi.Usd.RateFloat;
}
}
public partial class BitcoinInfo
{
[JsonProperty("bpi")]
public Bpi Bpi { get; set; }
}
public partial class Bpi
{
[JsonProperty("USD")]
public Currency Usd { get; set; }
}
public partial class Currency
{
[JsonProperty("rate_float")]
public double RateFloat { get; set; }
}

Wrote and ran that as a joke, but was stunned to see it fluctuate like that every minute or so.

All of the random number generators based on a commodity's price produce "brown" noise - the price varies in a manner similar to Brownian motion.
Any idea how to convert this to "white" noise?
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

It's intended for an 8 bit processor and can be asembled for 8 bit random values or for 16 bit. When i tested it. it had a nice Gaussean bell curve distribution, so the random values are indeed random enough for noncritical applications.

What processor? I don't recognize "GLO" and "PLO", etc.

I have not checked, but it may even work on a CDP1801, and certainly it will also run on a CDP1804. CDP1805 or a CDP1806.
