#hacking In anticipation of the presidential election, Microsoft Corporation and the US Cyber Command started taking down Bots that Russian and Iranian hackers used to launch cyberattacks.
The hackers struck back. They took over the computers of two hospital systems and a small town in Georgia (Voting). They have warned that they have 400 other hospitals as targets. They have demanded big payments in cryptocurrencies to give an encryption key to allow the owners of the computer systems to get their computers back. (People who pay the ransom sometimes do not get their computers back.)
Early last year, I got hit with ransomware. A sinister machine voice came on my computer and warned me to pay $5,000 in Bitcoins to get my computer back. I do not bow down to black mailers. I took my computer to The Geek Squad. It took them a week, but they got control of my computer back to me. The bill was $250.00.
Everyone hackers use a trick to get into computers. They send out a very convincing email with an innocent-looking link. Some hapless person clicks on the link. The hackers are now inside the computer and can look at data, steal data, destroy data, or lock up the computer and demand a ransom to give it back.
Elena's employer puts every employee who uses the computer system through intense training in computer awareness and security. The moral of this story is that you should be super careful before you click on any link.

Haha, I don't believe it. You got a sinister voice, and that's it.

The way ransomware works is that it encrypts all your files and to decrypt it, you have to get the key from them - otherwise it's trivial to get around it.

This is really the fault of Microsoft. It's actually easy to prevent viruses. The way the XBox and PlayStation works is that executables are checked for a signed signature. If it's not properly signed, it doesn't run. It would be trivial to have all executables be signed, even if signed by the user themselves, and if a program is causing havoc, just disable all programs signed with that signature.

You would have to manually OK (just once) a new signature, or, have a 3rd party sign off on the executable taking liability for the program.

This problem was solved 20 years ago, and it's not implemented because there's no interest in actually securing your machines and devices - at least from the point of view of the government.
