Just recently on May 12 (Friday), 2017, this malware has spread over the internet and affected 150 countries around the globe, infecting more than 2,30,000 computers till now. WannaCrypt ransomware is also known with its popular names as "WanaCrypt0r" or "Wanna Decryptor" or "WannaCry" malware. This ransomware intrudes on Microsoft Windows operating devices and encrypts data files stored on the computer. To decrypt and restore the files back, it then demands for hefty payments as ransom fee through the renowned Bitcoin cryptocurrency, leaving no way to get traced.

After WannaCrypt ransomwares intrude on your device, the first step of it is to drop a password protected .zip file where this infection is stored. It contains files names as b.wnry, c.wnry, r.wnry, s.wnry, t.wnry, u.wnry, taskse.exe, taskdl.exe.

It then initiates its encrypting process by connecting through servers and running some administrative commands in the background. With the commands executed, it encrypts the vital files of the victim's computer. It first makes a copy of original file, encrypts it and deletes the original file. In addition to this, WannaCrypt also installs a timer program called as WanaDecryptor 2.0. This program highlights "Oops, your files have been encrypted!" message and runs a real-time timer with a payment method involved to pay a hefty amount through bitcoin cryptocurrency as a fee to restore files. Also, if the timer runs out, the fee to restore the files back may get doubled up. It also makes periodic changes to your wallpaper and messages on the screen to annoy you and fall in the trap for a ransom payoff.

Part 3. How to Protect Your Computer from Virus-Like WannaCrypt

Despite the fact that WannaCrypt largely affected businesses and organizations, most people are worried about their personal computers being targeted. This is after the group that leaked the U.S National Security Agency hacking tools used to launch WannaCrypt claimed that it would release malicious codes. So how do you protect your computer from the possible wave of viruses, malware and cyber threats that may be looming?

1. Stay up-to-date

OS developers like Microsoft periodically update computer operating systems to fix security holes and stay in tune with the latest advances in technology. Upgrade to the latest operating system, or you install the latest software updates and manufacture’s patches. This should be done regularly to ensure that your computer has the latest protection. We recommend that you turn on auto updates where available.

How to Install Windows Updates On Windows 7

2. Install Antivirus Software

A reliable security software will prevent attacks from most common threats, but it won’t provide you with “full protection.” This is because when hackers come up with something new, it takes a little while before developers can add it to their anti-virus definitions. So you should always ensure that your anti-virus software has the latest definitions. Don’t forget to run it every day.

3. Keep Your Firewall Turned On

Firewalls protect your computer from fraudsters who might be trying to gain access to your PC to steal passwords or other sensitive information. Note that Both Mac and PCs operating systems come with built-in firewalls that need to be enabled. When setting up your computer for the first time, you simply need to say “Yes” to this security protection option. You can also purchase firewall software programs.

How to Turn On Windows Firewall in Windows 10: Press both "Win + X" key combination and select "Control Panel". Type "firewall" in the search box and click the "Windows Firewall" link. Select the "Turn Windows Firewall On or Off" link located on the left pane. Check the "Turn on Windows Firewall" and then click the "OK" button.

4. Always Stay Alert

Don’t ever download files from unknown sources or click on links that you don’t recognize. Exercise extra caution with your emails since there could be an embedded link or attachment that’s infected. WannaCrypt is a perfect example of ransomware that gains access to computer systems via email attachments. The ransomware locks you out of your computers and then encrypts your files. To receive a decryption key, you are expected to pay $300 in Bitcoin, a price that’s doubled after three days. Just be cautious, and you’ll avoid viruses like WannaCrypt.

5. Prepare for the Worst- Back Up Your Data

At times, you can do everything right and still fall prey to virus attacks. There’s no full proof protection since hackers are always a little bit ahead. If you don’t already have a backup routine, we recommend that you start saving copies of all your important files and make it a regular habit. Once you have backups, you’ll also be protecting your computer from other data loss scenarios such as hard drive failure, accidental formatting, your house burning down, etc. There are multiple backup programs to choose from including the use of External Hard Drives, Windows Backup, Free Backup Programs (Cobian Backup), Paid Backup Programs (Paragon Hard Disk Manager Suite), Cloud Backup (Dropbox, Google Drive, SkyDrive and more), etc.
