How to Defend Against Ransomware Attacks

Ransomware is bad  i.e. your files are encrypted – what should be done?  At this point it is too late – the computer and or files are encrypted and the only way to recover them is to decrypt or restore from backup. (THIS IS WHY A BACKUP IS SO IMPORTANT).

 

There are some possible ways to decrypt a few select ransomware infections. _If_ the criminal hacker wrote a bad program that allows an ingenious  programmer to develop a decrypt program. These  are very rare and you can count your lucky stars if that is the case for you (search decrypt ransomware – and your mileage may vary).

The best way to recover from a ransomware attack is to have a restore data and operating system method. This will take time, but at least you can come back from this attack.

Her is also an image I have previously put out – the abbreviated history of Ransomware – Notice in 2014 the game changed when criminals made hundreds of million$ of dollars.

Let’s say you do _not_ have a backup, and thus cannot have a restore ready. Now what?  Now you can reinstall from scratch – reinstall your operating system – like Windows10 (or a server OS if it is a server). then you have to reinstall all the applications (Office, accounting, adobe, and more).

What about your data? I.e. maybe a resume, or the actual IRS tax data from the last 5 years?  Hmmm, yes it is gone. since you cannot decrypt, it is history.

So can you keep operating your business with no data? Maybe – do you have any paper copies? did you keep some data on the cloud? with a friend? In your email stream?  So maybe you can recover a few files here and there.

But one can see that in 6 months some businesses have called it quits instead of doing all this work.
