What is Ransomware?


Actually Ransomware is a tool created by American Security Agency NSA and stolen by hackers called Shadows Brokers and they edited and misuse as destroying other system for getting money.
Ransomware is a type of hacker virus attack for stealing your money. They will lock your computer and ask money to get back your system. Normally Ransomware are two types.

Second one encryption Ransomware allows you to open your system but all your files are encrypted with a secret code. So you can’t open your files. In both case, hacker demands money to get back your computer or files.

When I heard about Ransomware first, I thought that I can remove the virus and get back my file by formatting my Operating System. But after I learnt more, I understood that normal recovery is not possible because new Ransomware WannaCry or WannaCry   viruses lock the system as well as encrypt files. So we can’t get back our files even you connect your storage hard disk into a non-attacked system.

Email Attachments

Normally email attachments are the main source of the virus. In my case, I got many spam emails with unknown attachments that says a package of item is waiting for home delivery and attached file of data contains more details.

One day I downloaded the attachment to understand the file, which was an encrypted zip file contains a single JavaScript js file.

Ransomware spread though network from a system to another connected system through networks mainly LAN network in offices.

Removable Devices like Pen drive

How can you rid out from Ransomware?


Prevention is better than cure. Let us prevent the virus. So we must take care about the attacks. Now there is no much time to do. So these are the security or prevention methods in order of security.

  • Backup up your sensitive and important files.

You must backup your files by copying into another independent, secured, and not networked system using a pen drive. Or make a copy of files in to a pen drive, portable hard disk or to online cloud storage. Remember that, if you get attacked, then you can’t get back your files without paying money to them.

Now I started to back up my important files into my desktop system.

  • Use updated Security Software

You must use a security providing software like antivirus, defender, security essentials, etc. If you are at Windows, then it is best to use Windows Security Essentials with an extra antivirus.
It is true that most of people use outdated antivirus. Most of antivirus provide freeware for personal usage. But people download and use their paid version up to the free date. After date validity they will not protect you. So always use freeware if you can’t buy an original one. And update antivirus regularly or turn on auto-updating. ( I use Avira)

  • Update your Windows Version:

This is the very important method to protect your system. I make this point into third one because it is not easy to update the system if it is an office system.
       Many offices still use 20 years old, outdated, non-supported operating system Windows XP. Windows officially stopped their support for Windows XP. So never give you any security update for protect your system. So you must update your OS into a latest version like Windows 10. Ransomware already affected on Windows 7 in many countries. Try to buy a genuine version always.

  • Download and Install Windows Security Update MS 17010 Patch


       If you are using old Windows version including all versions before Windows 10, then that contains a security loophole SMB, then download and install Windows Security Update MS 17010 Patch to overcome this issue.

  • Block 139,445,3389 Ports on Firewalls

Normally Ransomware access your system though ports 139, 445 and 3389. If you are using old operating systems like Windows XP, then just open your Windows Firewall and block these ports.

  • Never download Unknown Email Attachments:

As we shown in above, email attachments are the main source of this attack. So never open any unknown email attachments.

  • Don’t open unknown Links:

Like email attachments, virus may get downloaded to your system by clicking unknown links that shown in emails, untrusted websites etc.

  • Use Pop blocked in your Browser:

Most of virus links comes on popup browser windows by visiting untrusted websites. If you install any popup blocker, that protects you from generating such popup windows.

  • Disconnect from Networks if you attacked

If your system is attacked, then kindly remove network connection for preventing spreading out to other devices.
