Infection live with WANNA CRY Ransomware and methods of protection
The destructive infection in recent years is a computer which is called Ransomware WannaCry.
Where did WannaCry?
Where he did not know exactly, but we know it was built on the stage of spyware tools subtracted from NSA (SRI Americans) that the NSA used them for espionage. The tools were based on some vulnerabilities in Windows that NSA has not reported to Microsoft, were stolen and put on the Dark Web, where some ideas put them to work.
Actually very suspicious!

WannaCry has affected almost all the American continent.
How does a Ransomware?
Simple:
1. get infected
2. The files are encrypted ICI
3. You have to pay if you want to decrypt them
If you are an individual and you have two or three selfies soaked on a PC, not a big problem, but if you are a big company and your entire database is encrypted, then… .Oops - WannaCry.
What says the message displayed WannaCry?
In short, it says to pay $ 300 if we want to decrypt the files, if not… .adio.
There was even a time limit, 7 days, then you can not decrypt the files.
After three days the redemption amount is increased from the 300 600 dollars as moneylenders.
Below is the message in Romanian!
How do we protect the ransomware?
1. You update to Windows. (important)
2. Back up important data on an external hard drive that you will be disconnected after backup. (very important)
3. Use a security solution against ramsomware's
4. Do not install pirated software.
5. Do not visit suspicious sites.
6. Do not click on any attachments from email.

The best solution against viruses of all kinds is: Better safe than bad.
It's bad parse this ransomware.
Cristi that free tool launched by Bitdefender anti-ransomware is for all types of ransomware, or just one?
We'll test and see ... in another tutorial. I couldn't say "belly" because I didn't use such tools.
Bitdefender is software that against ransomware and is doing great for any attack before!

Known threats are eliminated by antiviruses. The unknowns, ie "zero days" (https://en.wikipedia.org/wiki/Zero-day_(computing) ) infects you without the possibility of detection.

4. When PC window
5. You put your head and pray quilt

False, on the contrary you can always connect to it a usb, cd, dvd or even a viral external HDD and let's not forget that an antivirus that is not updated in time becomes useless.
The safest PC is the one who has installed and Linux Mint no longer joking about viruses in linux just does not exist like that just the bad Windows suffer.
I think the best solution would be the dedication laptops / PCs and a virus not to touch your devices
I I put a picture Patriarch Daniel Desktop and screen saver bell Dani so I'm sure that will not have problems with virus
His Holiness Patriarch aka Daniel is overkill in my opinion. A bottle of holy water-original that work wonders on the base plate.
Hello.
How can I download virus to test a virtual machine? Specifically, from where you downloaded. I'd like to try it on linux.
Now seriously, as I see I see that has asked anyone above about that, we leave nine download virus PTR test the virtual machine or not ptr our revenge on enemies, sending them on facebook, mail and they obviously choir click :))
I can not do it, sorry.
"Back up important data to an external hard drive that you will disconnect after backup"
But a backup to the cloud (like OneDrive) ???
Go, but I thought the safest way (fenced external disk) where, even if you fall the net, you will still be able to access the data.
Last year my PC was infected with the LOCKY virus. I noticed that it encrypted certain files e.g. doc, jpg, dbf etc ... but on the computer I had a file that had the extension .jpg-large and I didn't know how to encrypt those. I would like to ask you if you would rename an extension to an archive ex. from .zip to do it .arhivvv does it still encrypt the file?
Thanks a lot!
Cloud is affected by WANNA CRY Ransomware?
Unaffected, but it may be a way of spreading.
From the "cloud" you can receive an email with an attachment, or a month on a social network, which is also in the "cloud".
Suffered with another version of Ransomware - it encrypted the files in Dropbox. After synchronizing the affected computer, the ones from Dropbox were also encrypted.
Only 100% secure solution for now is to save data periodically.
