Protect yourself from Ransomware

How devastating would it be for your business if your computers were locked?

  • No access to customer files

  • POS locked

  • forms, documents, LOGOS, photos all locked

What is ransomware?

Ransomware is a sophisticated piece of malware that blocks the victim’s access to their files, and the only way to regain access to the files is to pay a ransom (but this also rarely works).

There are two types of ransomware in circulation:

  1. Encrypting ransomware, which incorporates advanced encryption algorithms.
    It’s designed to block system files and demand payment to provide the victim with the key that can decrypt the blocked content.
    Examples include CryptoLockerLockyCrytpoWall and more.
  2. Locker ransomware, which locks the victim out of the operating system, making it impossible to access the desktop and any apps or files. The files are not encrypted in this case, but the attackers still ask for a ransom to unlock the infected computer.
    Examples include the police-themed ransomware or Winlocker.

Some locker versions can even infect the Master Boot Record (MBR).
The MBR is the section of a PC’s hard drive which enables the operating system to boot up.
When MBR ransomware strikes, the boot process can’t complete as usual and prompts a ransom note to be displayed on the screen.
Examples include Satana and Petya families, these are the one from the latest attacks that have had devastating effects in the Ukraine and Russia.

Petya is the version that took down the Cadbury factory this week in Tasmania.

So how do you protect yourself against these attacks?

  1. Keep your operating system up to date. are you running the latest version of Windows (Windows 10)
  2. Make sure you have Windows automatic updates turned on (this will keep any patches and security updates applied to your PC)
  3. Do you have a quality anti-virus software installed with the latest updates? (The Valaxus team can install or update anti-virus software)
  4. Hard backups or sercure cloud storage with multiple versions of files that can be resorted (Valaxus can offer secure off-site cloud backup solutions using only the best secure Australian data centers)
  5. Be vigilant, alway be wary of email from someone you don’t know. (we have email come through a couple of times a month that are suspicious with attachment to open. some examples are below)
