The ransomware outbreak continues running out of control. It preys on an increasing number of businesses and home users making important data files useless by utilizing powerful crypto systems such as AES or RSA.

This sector of cyber-crime creates an enormous under-ground market. Based on a fairly recent investigative study, just one ransomware type known as Cerber is able to drive an annual profit of around} 2 million dollars.

How should computer users withstand such a robust enemy? Surprisingly, it is very easy to prevent disastrous ransomware consequences in many cases. Please note, it also doesn’t actually mean any additional fees or charges. Below is a bunch of helpful protection ideas to remain safe and do not pay a cent.

  1. Improve your spam defense

Ransomware creators use botnets to deliver significant portions of spam emails distributing their destructive malware. Fortunately, newest email solutions include modifiable anti-spam capabilities. Think about modifying your spam filtration system. Crank it up to maximum to ensure that virus-related messages cannot get in your mail box.

  1. Block dangerous file extensions

Nearly all ransom Trojans come with infected email attachments. For that reason, it’s a smart idea to configure your email program to stop incoming emails with potentially unsafe items on board. Our list of such extensions: .pif, .cmd, .bat, .scr, .vbs, .rtf. docm, .rar. .zip, .js, .exe.

Any attachment that asks to activate macros in Office docs or wants to execute scripts should be blocked too. So it’s seriously the right time to make sure you toggle {your|to check your email security settings} email security settings.

  1. Create Software Restriction Policies

In contrast to your everyday programs, ransomware is most likely to execute from LocalAppData, AppData, or Temp folders on host devices. By configuring the proper Software Restriction Policy within Local Group Policy Editor, you may be certain nothing dangerous executes from these locations.

  1. Change the name for vssadmin.exe

Having infected your PC, new ransomware infections will try to erase all Shadow Volume Copies by launching the vssadmin.exe and entering the: Delete Shadows/All/Quiet command. By doing this, the virus does not give an opportunity to its victims to restore files from previous versions. That is why it’s advised to change the name of the vssadmin.exe process a different name in order that ransomware could not allocate and delete previous versions of your files.

  1. Maintain Windows Firewall and additional firewalls turned on

Nearly all ransomware families have to connect to their C&C servers to get necessary keys needed during the encryption process. Although, Windows Firewall and additional firewall app may detect and stop this kind of traffic and activity preventing the virus from encrypting data thus making the attack unfinished.

  1. Beware of remote services

A virus called the Surprise Ransomware hit the news in March 2016. The attackers exploited the TeamViewer remote desktop program app to mount and manually run ransomware on remote devices. To prevent such issues, make sure to establish two-factor authentication when logging into remote services.

  1. Back up

Lastly, the most important rule is to create backups of most valuable data files that you cannot lose. You will find plenty of various cloud providers offering free storage space. You can also use removable disks to keep additional copies of important files. Do not backup your data using mapped drives or solutions that are syncing on regular basis. Do the backup once in the evening and immediately disconnect that storage device till the next time.

These methods are no panacea; however, they will keep the greater part of ransomware infections away from your devices. Again, it’s hard to overestimate the significance of data backups.
