Mac's and machines with Lynux OS get hit too.
Ransomware locks down important file folders. Has little to do with the operating system being used. The way the vast majority of ransomware attacks occur is; if some employee clicks on the wrong E-mail link, opens a file sent by a Facebook 'friend', or sticks an infected USB drive in their work machine.
Actually, to even function, it kinda does. I'll explain.
You see, for the ransomware to know what files to lock down, it first has to know which OS it's dealing with in order to know where all the necessary files are to infect/create to gain control of your computer. And it has to know the common pathways are to each file. This differs between Windows and Linux.
It cannot think this on it's own. This information has to be pre-programmed into the source code of the ransomware itself. And the typical OS of choice for ransomware is Windows. Because it's so ubiquitous and universally share the same file structure. If you're a ransomware creep and you want to get the most return from your scam, you want to infect as many computers as possible, This can only be done on a mass scale with Windows computers.
That's why the operating system matters and Windows ransomware doesn't work in Linux and vice-versa. Both systems are completely different in both their language and file structure.
That's not to say there isn't Linux/Mac malware/ransomware in the wild. There is. But because of the extra security hoops of Linux, it's still extremely rare because it still can't get very far. For Linux malware to get into your core system to access your files, you have to give it I.T. level root access permissions.
So if somebody in sales clicks on that irresistible "TRIPLE YOUR SALES OVERNIGHT!!!" email attachment, they will only get a prompt for a system admin log-in warning if the attachment contains system modification instructions for Linux. And if the user doesn't have root level system access, the file is unusable. Which will automatically give away what it is because any untainted, standard file won't do that. And the whole thing can be contained, right there.
Windows is a sieve because nearly all kinds of ransomware/malware instructions look for that ubiquitous C:\WINDOWS\ file to begin their dirty work. It's the most popular OS. And that's why it's such a target. Core system files used to execute the ransomware are found in exactly the same places across all Windows systems. It's the fatal flaw that's even making Microsoft yell uncle and embrace Linux.
In security enhanced, proprietary versions of Linux. (Not the free consumer garden varieties out there like Ubuntu or Debian, I'm talking about the high end kind you'll need a massive team of professional system developers to create via a license), you could change the entire system and kernel itself completely to customize it into a proprietary systemwide OS, encrypted on every level from music servers to receptionist desks. It's what Oracle does. That could only run on specific proprietary security enhanced hardware, if you like extra layers, too.
And as long as the proprietary source code remains a guarded corporate secret that would make the Coca-Cola formula and KFC chicken look like Jell-O recipe ads in
Better Homes & Gardens, everything should be fine. The tech is already here.
The trouble with that though is such a elaborate system won't be cheap and it will probably take several years to develop into something professional major-market cluster grade. And since what I've described would be (and not just theoretically, but
is) a complete, in-house OS of itself (not a prefabricated patchwork of Windows computers and servers), specifically designed top to bottom for broadcast media, it would need
constant ongoing upgrade and development.
So there's
another brand new sub-industry within an industry. Just
bustling with tech jobs nobody ever saw coming 20 years ago.
But seriously, if the suits were smart, they'd get right on it and put together a team with a mission. Media of any kind, especially radio, can't afford this. And consumer grade solutions like Windows won't do anymore.
