CryptoLocker – Virus Alert

It’s time to warn you again.

Dear customers & business partners, associates and friends.

This is Mark from Advanced Technology. It is important that you take the time to read this entire e-mail, to protect your data and your business. You might have heard about this in the news over the last couple of days.

Please pass on this message to your staff, so that they are aware of the current threat.

Some of you might remember me sending a similar warning to everybody about a virus call “CryptoLocker”.

In the last couple of days, new variants of these viruses have hit clients in the Coffs Harbour area.  This one is called “CryptoWall 4.0” and it has already impacted businesses in our area!

It is a another bad wave of this type of virus, and again virus protection companies are scrambling to catch up with this one, as it changes frequently to elude the virus scanners. In other words: it can affect you if you are not careful even though your virus protection is active and up-to-date.

About the virus:
This time the virus came as a link in an email claiming to be Australia Post trying to deliver a package.

The link will send you to a very authentic looking web page where you’ll be asked to complete a CAPTCHA and it can either send you a file or run a script in the background which will kick off the process infecting your computer.

The below image is a screen shot from a similar fake Australia Post website, as you can see it is a very authentic looking web page and even the domain name appears, at a glance, to be correct but in actual fact is completely fake and its only function is to trick us into downloading a ransom-ware virus.

At the end the users gets a warning on a their files have been encrypted, while presenting information directing people to pay to decrypt all of their files.

It’s an especially dangerous situation in a business network, where the majority of the work is being completed and transferred on computers. What is even more treacherous about CryptoWall is its ability to hide itself on your computer, while encrypting your files and make them unusable.

How to protect your data:

  • NEVER open an attachment from an unknown source, which is vague, or is delivered via an “outside” third party with no personal name attached to it.  If this occurs in your email, delete it immediately.
  • NEVER click on a link in an email from an unknown source, which is vague, or is delivered via an “outside” third party with no personal name attached to it.  If this occurs in your email, delete it immediately.
  • ALWAYS check the URL that you are directed to is actually what you are expecting, for example, the Australia Post website is auspost.com.au not aus-post.org

 

What if one of our computers gets infected?

  • Shut down your computer immediately.
  • Unplug your network connection immediately (your blue network cable if your computer is a part of a network).
  • Contact Advanced Technology or your computer department immediately.
  • Get your IT help desk to clean out the virus and restore your data from the latest backup.

In closing, the message I am trying to spread is: Don’t panic but you need to be vigilant with files sent to you by other people.

Kind regards,
Mark
